GraphQL for ProcessWire

Recommended Posts

@Nurguly Ashyrov Hi, is there a way to add images/files to a page with the updatePage method ? If not, do you plan to implement it or do I have to do this another way ?

Thanks again :)

Unfortunately not yet. I am planning to implement them. But I am a bit busy now and it would definitely take some time to implement it. For now, you will have to do it some other way. Sorry :(

When I go to GraphiQl interface, selector argument for template fields does not appear to be optional as it's in the screencast. However, if I provide a selector, it works as expected. Do I need to set up something on backend?

How it looks on my GraphiQL:

How it is in the screencast

Hi @abdus. You are good to go actually. The argument is required only when there is an exclamation mark after it. It does not have to be = false. Sorry for the confusion, the way I explain it in screencast is a bit misleading. To sum it up, if there is an exclamation mark "!" at the end, it means it is required, of not then it is optional. The = false part means, the default value is false. I know, it sounds stupid. It was a bug in the library I used for this module. I updated it to the latest version since the screencast and now it shows correctly. The = false part is actually is a bug in older version of the module. You probably installed the latest version which shows correctly.

So, your version is actually is the way it supposed to be. The version in the screencast is a bit misleading, but still correct.

Thanks for the clarification. The problem is that if I dont specify any selector, I get empty array, also an error

chrome_2017-04-06_15-50-19.thumb.png.00e9aa75f76ebead5470e0a37f80b24b.png

But if I specify a selector, it all works fine

I'm not sure if this is the expected behavior.

Well now I am embarrassed. :( So sorry. It turns out upgrading to the latest graphql library broke some stuff. For some reason I did not check the queries without the selectors. I made some fixes. This should solve your problem. Please get the latest version and try again.

Thanks a lot for the changes, it works without a problem now :)

Also, is it possible for you to add some hookable functions to the module so that we can add custom queries and mutations? Inside Schema::build(), query and mutation fields are defined, maybe split build() method into ___getMutations and ___getQueries, then we can modify $event->returns inside hooks to add our own fields? Something like this maybe:

<?php
// maybe build parameters in 
// /ProcessGraphQL/ProcessGraphQL.module

public function ___getQueries() {
  // build an assc. array of FieldInterface objects
  return [...];
}

public function ___getMutations() {
  // build an assc. array of FieldInterface objects
  return [...];
}

public function executeGraphQL()
{
  // instantiating Processor and setting the schema

  $schema = new Schema($this->___getQueries(), $this->___getMutations());
  $processor = new Processor($schema);

  // ...
}

then inside Schema.php you would just use the provided fields.

<?php
class Schema extends AbstractSchema {
    private $queries = [];
    private $mutations = [];

    public function __construct($queries, $mutations)
    {
        // populate fields, perform checks etc
    }

    public function build(SchemaConfig $config)
    {
        $moduleConfig = Utils::moduleconfig();
        $query = $config->getQuery();
        $mutation = $config->getMutation();

        // add other query fields
        $query->addFields($this->queries);
        $mutation->addFields($this->mutations);
    }
}

It's a proof of concept, needs better separation of concerns etc, but it should work, why wouldn't it.

Or maybe use $moduleConfig instead of causing fragmentation.

<?php // Schema.php
public function build(SchemaConfig $config)
{
	// $moduleConfig is an instance of ProcessGraphQL module
	$moduleConfig = Utils::moduleconfig();
	$customQueries = $moduleConfig->___getQueries();
	$customMutations = $moduleConfig->___getMutations();

	$query = $config->getQuery();
	$mutation = $config->getMutation();

	$query->addFields($customQueries);
	$mutation->addFields($customQueries);
	// then populate your own fields etc.
}

Done! :)

The latest version now allows you to hook into getQuery & getMutation methods of the ProcessGraphQL class. Those hooks are solely there so you could modify the query and mutation operations. Here how it might look like in your template file.

<?php namespace ProcessWire;
use Youshido\GraphQL\Type\Scalar\StringType;

$processGraphQL = $modules->get('ProcessGraphQL');

wire()->addHookAfter('ProcessGraphQL::getQuery', function ($event) {
    $query = $event->return;
  
    $query->addField('hello', [
        'type' => new StringType(),
        'resolve' => function () {
            return 'world!';
        }
    ]);
});

echo $processGraphQL->executeGraphQL();

The above code will add a hello field into your GraphQL query that responds with the string "world!". You'll have to use the Youshido\GraphQL library that ProcessGraphQL module uses internally. The same thing could be done with the mutation operation via getMutation  hook method.

@Nurguly Ashyrov I am trying to build a mutation field for mailing list subscription that takes in email address and returns status code and error messages, if any. 

<?php namespace ProcessWire;
// /site/templates/graphql.php

use ProcessWire\Api\SubscriptionField;
require_once '../modules/ProcessGraphQL/vendor/autoload.php';

$processGraphQL = modules()->get('ProcessGraphQL');

wire()->addHookAfter('ProcessGraphQL::getMutation', function ($event) {
    $query = $event->return;
    $query->addField(new SubscriptionField());
});

echo $processGraphQL->executeGraphQL();

Here's my SubscriptionField definition

Spoiler

<?php namespace Processwire\Api;
// /site/templates/api/SubscriptionField.php

use Youshido\GraphQL\Config\Field\FieldConfig;
// others

class SubscriptionField extends AbstractField
{
    public function getType()
    {
        return new SubscriptionType();
    }

    public function resolve($value, array $args, ResolveInfo $info)
    {
        return [
            'statusCode' => 200,
            'errors' => [
                'no error'
            ]
        ];
    }

    public function build(FieldConfig $config)
    {
        $config->addArgument('email', new NonNullType(new StringType()));
    }
}

and my SubscriptionType class

Spoiler

<?php namespace ProcessWire\Api;
// /site/templates/api/SubscriptionType.php
use Youshido\GraphQL\Type\ListType\ListType;
// others

class SubscriptionType extends AbstractObjectType
{

    public function getName()
    {
        return 'Subscription';
    }

    public function build($config)
    {
        $config->addField('statusCode', [
            'type' => new NonNullType(new IntType()),
            'description' => 'The subscription status code. E.g. 200 if successful.',
            'resolve' => function ($value) {
                return (integer)$value->statusCode;
            }
        ]);

        $config->addField('errors', [
            'type' => new ListType(new StringType()),
            'description' => 'Human readable subscription errors. E.g. "Added to list!"',
            'resolve' => function ($value) {
                return (string)$value->errors;
            }
        ]);
    }

}

When I open the GraphiQL console, I get this error

chrome_2017-04-09_17-44-58.png.e7445fbe2fd0a032a0fcf2d9444d5ce0.png

I am not sure why PHP can't find the class, any ideas?

When I manually require field class (require_once 'api/SubscriptionField.php';), it resolves the class, but then cannot resolve others (error: Class 'Youshido\GraphQL\Field\AbstractField' not found)

@abdus First of all you don't need to import ProcesGraphQL's vendor.php file. It is done automatically when you do 

$processGraphQL = modules()->get('ProcessGraphQL');

Second is, I don't see where you include your /site/templates/api/SubscriptionField.php file into graphql.php. So replace the 

require_once '../modules/ProcessGraphQL/vendor/autoload.php';

with

require_once "./api/SubscriptionType.php";

in your graphql.php and it should work.

Also, your SubscriptionField class requires the public function getName().

Thanks for the guidance @Nurguly Ashyrov. The problem was that I wasn't including calling the module (and therefore not autoloading GraphQL classes) before I included mine. That was why it wasn't resolving.

<?php
// CORRECT
$processGraphQL = modules()->get('ProcessGraphQL');
require_once 'api/SubscriptionField.php';
require_once 'api/SubscriptionType.php';

// INCORRECT
require_once 'api/SubscriptionField.php';
require_once 'api/SubscriptionType.php';
$processGraphQL = modules()->get('ProcessGraphQL');

For reference here's a simple mutation field implementation

<?php
wire()->addHookAfter('ProcessGraphQL::getMutation', function ($event) {
    $query = $event->return;
    $query->addField('log', [
      	// define return object under type
        'type' => new ObjectType([
            'name' => 'Log',
            'fields' => [
                'result' => [
                    'type' => new StringType()
                ]
            ]
        ]),
      	// available arguments for the query
        'args' => [
            'text' => new StringType()
        ],
      	// what to do with the request
        'resolve' => function ($value, $args) {
            // process given input
          	// return object outline should be same as 'type'
            return [
                'result' => 'done. ' . $args['text']
            ];
        }
    ]);
});

When you refresh GraphiQL console, you get your new field!

Hi,

I just tried the module and get a JSON.parse Error because the query responded  this error:.

EDIT: Running on PHP 7.1 on Heroku and ext-mbstring was missing. I installed it and the error is away :-)

hi @Nurguly Ashyrov, I am planning to use this module to share content from one site to another. I got it up and running on my staging server but I would like to restrict access to the API data. How would you set up authentication to consume GraphQL data remotely?

Thx
Rudy

I Just played around with it a little. Looks awesome so far! It would be great if PageTable was supported, or is it already possible with a workaround?

Hey, Rudy! I couldn't fully understand your use case. I guess you want to restrict access to certain entities, like your other site. It is very easy to restrict access to certain ip address. Just before serving GraphQL API you could check for the requested entities ip address and behave accordingly. For example:

<?php
if ($_SERVER['REMOTE_ADDR'] == 123.234.34.1 ) {
  echo $modules->get('ProcessGraphQL')->executeGraphQL();
} else {
  echo 'Access Denied';
}

I can't say for sure if that's what you are asking though. If not, please give more details on what you are trying to achieve.

@Nurguly Ashyrov,

Your solution is actually quite simple and should work in my current case. A proper authentication (oAuth or JWT or even a simple token exchange) would be ideal.

My current use case: I have a master PW website with all the content. I also have 5 other websites that draw content from the master site. Essentially I want to treat the master site as an API server, serving data via GraphQL.

Thx
Rudy

PageTable is not supported yet. To be honest I am very busy right now and don't have much time to update this module. So I can't say when additional features will be added. Until then, you'll have to figure out your own way. Sorry :)

Hi @Nurguly Ashyrov, this looks like a great module - thank you for developing it!

I'm a complete noob to the world of GraphQL, and have been trying for two days to get this module running in combination with Ember.js. If I could get it to work, it sure would be a glorious combination. But so far it has been pretty frustrating :o

One thing that I keep running into, is that your implementation always returns an array of pages, using the 'list' field* inside the query.
However, this makes it impossible to request a single page. Even when using something like limit=1 in the selector. 

For instance, I could imagine this to work fine

{
  basic_page(s: "name:contact") {
    first {
      id
      name
    }
  }
}

Which then could return 

{
    "data": {
        "basic_page": {
            "first": {
                "id": "1017",
                "name": "contact"
            }
        }
    }
}

Basically, any of PW's regular PageArray methods to find something would be a welcome addition ( ie. ->eq(n), ->get(selector), ->first(), ->last(), etc.)

Is this something I can achieve with the getQuery hook? Or in another way?
Thanks in advance for any pointers or help. 

(* I have to say, this use of the field keyword is very confusing for a long time PW user).

Hey everyone!

It's been a while since I last had a time to work on this module. But now I finally managed to focus on this module. So here are the latest updates.

The codebase of the module grew very big and the more features I added the more time I had to spend to make sure the changes I made does not break anything. Because I had to manually verify if everything works as expected. After long night hours of trial and error I managed to setup tests for this module. Tests will help us quickly add/remove features as needed, because now there is no need for manually verifying all edge cases. Also I setup the Travis-CI so people can contribute more confidently and I can merge pull requests without worrying! There are already bunch of tests, but there is still some I'll be adding.

🎉 ProcessGraphQL.svg?branch=master 🎉

I will add some documentation on how to run tests locally in github wiki pages soon and let you know here.

Another thing to note is that the master branch of our module no longer tracks the vendor code. This means that if you download the master branch and put it into your /site/modules directory it will not work. Instead you should use release builds that are a cleaned version of the module. It includes required vendor codes and does not have extra files that are not relevant to ProcessWire. Like presentation gif images, test files and so on. This makes the module size smaller!

Hey @eelkenet!
That seems reasonable to me. I was planning to add those fields. Didn't have time till now. I'll let you know as soon as I implement them.

You won't be able to add those fields via getQuery hook btw. The getQuery hook is there for very trivial custom fields to be honest. Like your api version number, or your contact data or anything you want to send via GraphQL api without creating templates, fields and pages for it.

More updates!

Here is what was added since my last post:

  • FieldtypeDatetime now supports format argument. Which allows you to pass PHP date format string and retrieve your datetime values formatted the way you want. Besides FieldtypeDatetime fields, the built-in fields created and modified are also support new format argument.
  • FieldtypeOptions is now supported.
  • first and last fields on PageArray types are now supported. As per @eelkenet's request. See above post for details on those.
  • Finally, now there is a way to add support for any fieldtype you want via third-party module. What you need to do is create a module with the name exactly as the fieldtype you want to add support for with "GraphQL" prefix. So for FieldtypeMapMarker it would be GraphQLFieldtypeMapMarker. Then you need to add three required methods and install it. This will automatically add GraphQL support for your desired fieldtype and it will be available in your GraphQL api. Checkout the documentation and an example module for reference.

      ---- INITIAL POST FROM 2019-05-25 ----
      I wanted to let you know that I am currently working on a new ProcessWire module that fully integrates the Snipcart Shopping Cart System into ProcessWire. (this is a customer project, so I had to postpone the development of my other module GroupMailer).
      The new module SnipWire offers full integration of the Snipcart Shopping Cart System into ProcessWire.
      Here are some highlights:
      simple setup with (optional) pre-installed templates, product fields, sample products (quasi a complete shop system to get started immediately) store dashboard with all data from the snipcart system (no change to the snipcart dashboard itself required) Integrated REST API for controlling and querying snipcart data webhooks to trigger events from Snipcart (new order, new customer, etc.) multi currency support self-defined/configurable tax rates etc. Development is already well advanced and I plan to release the module in the next 2-3 months.
      I'm not sure yet if this will be a "Pro" module or if it will be made available for free.
      I would be grateful for suggestions and hints!
      (please have a look at the screenshots to get an idea what I'm talking about)

      I have had this module sitting in a 95% complete state for a while now and have finally made the push to get it out there. Thanks to @teppo for his Hanna Code Helper module which I referred to and borrowed from during development.
      http://modules.processwire.com/modules/hanna-code-dialog/
      https://github.com/Toutouwai/HannaCodeDialog
      HannaCodeDialog
      Provides a number of enhancements for working with Hanna Code tags in CKEditor. The main enhancement is that Hanna tags in a CKEditor field may be double-clicked to edit their attributes using core ProcessWire inputfields in a modal dialog.
      Requires the Hanna Code module and >= ProcessWire v3.0.0.
      Installation
      Install the HannaCodeDialog module using any of the normal methods.
      For any CKEditor field where you want the "Insert Hanna tag" dropdown menu to appear in the CKEditor toolbar, visit the field settings and add "HannaDropdown" to the "CKEditor Toolbar" settings field.
      Module configuration
      Visit the module configuration screen to set any of the following:
      Exclude prefix: Hanna tags named with this prefix will not appear in the CKEditor toolbar dropdown menu for Hanna tag insertion. Exclude Hanna tags: Hanna tags selected here will not appear in the CKEditor toolbar dropdown menu for Hanna tag insertion. Background colour of tag widgets: you can customise the background colour used for Hanna tags in CKEditor if you like. Dialog width: in pixels Dialog height: in pixels Features
      Insert tag from toolbar dropdown menu
      Place the cursor in the CKEditor window where you want to insert your Hanna tag, then select the tag from the "Insert Hanna tag" dropdown.

      Advanced: if you want to control which tags appear in the dropdown on particular pages or templates you can hook HannaCodeDialog::getDropdownTags. See the forum support thread for examples .
      Edit tag attributes in modal dialog
      Insert a tag using the dropdown or double-click an existing tag in the CKEditor window to edit the tag attributes in a modal dialog.

      Tags are widgets
      Hanna tags that have been inserted in a CKEditor window are "widgets" - they have a background colour for easy identification, are protected from accidental editing, and can be moved within the text by drag-and-drop.

      Options for tag attributes may be defined
      You can define options for a tag attribute so that editors must choose an option rather than type text. This is useful for when only certain strings are valid for an attribute and also has the benefit of avoiding typos.
      Add a new attribute for the Hanna tag, named the same as the existing attribute you want to add options for, followed by "__options". The options themselves are defined as a string, using a pipe character as a delimiter between options. Example for an existing attribute named "vegetables":
      vegetables__options=Spinach|Pumpkin|Celery|Tomato|Brussels Sprout|Potato You can define a default for an attribute as normal. Use a pipe delimiter if defining multiple options as the default, for example:
      vegetables=Tomato|Potato Dynamic options
      Besides defining static options as above, you can use one Hanna tag to dynamically generate options for another. For instance, you could create a Hanna tag that generates options based on images that have been uploaded to the page, or the titles of children of the page.
      Your Hanna tag that generates the options should echo a string of options delimited by pipe characters (i.e. the same format as a static options string).
      You will probably want to name the Hanna tag that generates the options so that it starts with an underscore (or whatever prefix you have configured as the "exclude" prefix in the module config), to avoid it appearing as an insertable tag in the HannaCodeDialog dropdown menu.
      Example for an existing attribute named "image":
      image__options=[[_images_on_page]] And the code for the _images_on_page tag:
      <?php $image_names = array(); $image_fields = $page->fields->find('type=FieldtypeImage')->explode('name'); foreach($image_fields as $image_field) { $image_names = array_unique( array_merge($image_names, $page->$image_field->explode('name') ) ); } echo implode('|', $image_names); Choice of inputfield for attribute
      You can choose the inputfield that is used for an attribute in the dialog.
      For text attributes the supported inputfields are text (this is the default inputfield for text attributes so it isn't necessary to specify it if you want it) and textarea. Note: any manual line breaks inside a textarea are removed because these will break the CKEditor tag widget.
      Inputfields that support the selection of a single option are select (this is the default inputfield for attributes with options so it isn't necessary to specify it if you want it) and radios.
      Inputfields that support the selection of multiple options are selectmultiple, asmselect and checkboxes.
      You can also specify a checkbox inputfield - this is not for attributes with defined options but will limit an attribute to an integer value of 1 or 0.
      The names of the inputfield types are case-insensitive.
      Example for an existing attribute named "vegetables":
      vegetables__type=asmselect Descriptions and notes for inputfields
      You can add a description or notes to an attribute and these will be displayed in the dialog.
      Example for an existing attribute named "vegetables":
      vegetables__description=Please select vegetables for your soup. vegetables__notes=Pumpkin and celery is a delicious combination. Notes
      When creating or editing a Hanna tag you can view a basic cheatsheet outlining the HannaCodeDialog features relating to attributes below the "Attributes" config inputfield.
      Advanced
      Define or manipulate options in a hook
      You can hook HannaCodeDialog::prepareOptions to define or manipulate options for a Hanna tag attribute. Your Hanna tag must include a someattribute__options attribute in order for the hook to fire. The prepareOptions method receives the following arguments that can be used in your hook:
      options_string Any existing string of options you have set for the attribute attribute_name The name of the attribute the options are for tag_name The name of the Hanna tag page The page being edited If you hook after HannaCodeDialog::prepareOptions then your hook should set $event->return to an array of option values, or an associative array in the form of $value => $label.
      Build entire dialog form in a hook
      You can hook after HannaCodeDialog::buildForm to add inputfields to the dialog form. You can define options for the inputfields when you add them. Using a hook like this can be useful if you prefer to configure inputfield type/options/descriptions/notes in your IDE rather than as extra attributes in the Hanna tag settings. It's also useful if you want to use inputfield settings such as showIf.
      When you add the inputfields you must set both the name and the id of the inputfield to match the attribute name.
      You only need to set an inputfield value in the hook if you want to force the value - otherwise the current values from the tag are automatically applied.
      To use this hook you only have to define the essential attributes (the "fields" for the tag) in the Hanna Code settings and then all the other inputfield settings can be set in the hook.
      Example buildForm() hook
      The Hanna Code attributes defined for tag "meal" (a default value is defined for "vegetables"):
      vegetables=Carrot meat cooking_style comments The hook code in /site/ready.php:
      $wire->addHookAfter('HannaCodeDialog::buildForm', function(HookEvent $event) { // The Hanna tag that is being opened in the dialog $tag_name = $event->arguments(0); // Other arguments if you need them /* @var Page $edited_page */ $edited_page = $event->arguments(1); // The page open in Page Edit $current_attributes = $event->arguments(2); // The current attribute values $default_attributes = $event->arguments(3); // The default attribute values // The form rendered in the dialog /* @var InputfieldForm $form */ $form = $event->return; if($tag_name === 'meal') { $modules = $event->wire('modules'); /* @var InputfieldCheckboxes $f */ $f = $modules->InputfieldCheckboxes; $f->name = 'vegetables'; // Set name to match attribute $f->id = 'vegetables'; // Set id to match attribute $f->label = 'Vegetables'; $f->description = 'Please select some vegetables.'; $f->notes = "If you don't eat your vegetables you can't have any pudding."; $f->addOptions(['Carrot', 'Cabbage', 'Celery'], false); $form->add($f); /* @var InputfieldRadios $f */ $f = $modules->InputfieldRadios; $f->name = 'meat'; $f->id = 'meat'; $f->label = 'Meat'; $f->addOptions(['Pork', 'Beef', 'Chicken', 'Lamb'], false); $form->add($f); /* @var InputfieldSelect $f */ $f = $modules->InputfieldSelect; $f->name = 'cooking_style'; $f->id = 'cooking_style'; $f->label = 'How would you like it cooked?'; $f->addOptions(['Fried', 'Boiled', 'Baked'], false); $form->add($f); /* @var InputfieldText $f */ $f = $modules->InputfieldText; $f->name = 'comments'; $f->id = 'comments'; $f->label = 'Comments for the chef'; $f->showIf = 'cooking_style=Fried'; $form->add($f); } }); Troubleshooting
      HannaCodeDialog includes and automatically loads the third-party CKEditor plugins Line Utilities and Widget. If you have added these plugins to your CKEditor field already for some purpose and experience problems with HannaCodeDialog try deactivating those plugins from the CKEditor field settings.

      Wire Mail SMTP

      An extension to the (new) WireMail base class that uses SMTP-transport

      This module integrates EmailMessage, SMTP and SASL php-libraries from Manuel Lemos into ProcessWire. I use this continously evolved libraries for about 10 years now and there was never a reason or occasion not to do so. I use it nearly every day in my office for automated composing and sending personalized messages with attachments, requests for Disposition Notifications, etc. Also I have used it for sending personalized Bulkmails many times.

      The WireMailSmtp module extends the new email-related WireMail base class introduced in ProcessWire 2.4.1 (while this writing, the dev-branch only).
       
      Here are Ryans announcement.



      Current Version 0.4.2
      Changelog: https://github.com/horst-n/WireMailSmtp/blob/master/CHANGELOG.md
      get it from the Modules Directory Install and Configure

      Download the module into your site/modules/ directory and install it.

      In the config page you fill in settings for the SMTP server and optionaly the (default) sender, like email address, name and signature.
      You can test the smtp settings directly there. If it says "SUCCESS! SMTP settings appear to work correctly." you are ready to start using it in templates, modules or bootstrap scripts.


      Usage Examples
      The simplest way to use it:
      $numSent = wireMail($to, $from, $subject, $textBody); $numSent = wireMail($to, '', $subject, $textBody); // or with a default sender emailaddress on config page This will send a plain text message to each recipient.
       
      You may also use the object oriented style:
      $mail = wireMail(); // calling an empty wireMail() returns a wireMail object $mail->to($toEmail, $toName); $mail->from = $yourEmailaddress; // if you don't have set a default sender in config // or if you want to override that $mail->subject($subject); $mail->body($textBody); $numSent = $mail->send(); Or chained, like everywhere in ProcessWire:
      $mail = wireMail(); $numSent = $mail->to($toEmail)->subject($subject)->body($textBody)->send(); Additionaly to the basics there are more options available with WireMailSmtp. The main difference compared to the WireMail BaseClass is the sendSingle option. With it you can set only one To-Recipient but additional CC-Recipients.
      $mail = wireMail(); $mail->sendSingle(true)->to($toEmail, $toName)->cc(array('person1@example.com', 'person2@example.com', 'person3@example.com')); $numSent = $mail->subject($subject)->body($textBody)->send(); The same as function call with options array:
      $options = array( 'sendSingle' => true, 'cc' => array('person1@example.com', 'person2@example.com', 'person3@example.com') ); $numSent = wireMail($to, '', $subject, $textBody, $options); There are methods to your disposal to check if you have the right WireMail-Class and if the SMTP-settings are working:
      $mail = wireMail(); if($mail->className != 'WireMailSmtp') { // Uups, wrong WireMail-Class: do something to inform the user and quit echo "<p>Couldn't get the right WireMail-Module (WireMailSmtp). found: {$mail->className}</p>"; return; } if(!$mail->testConnection()) { // Connection not working: echo "<p>Couldn't connect to the SMTP server. Please check the {$mail->className} modules config settings!</p>"; return; }  
      A MORE ADVANCED DEBUG METHOD!
      You can add some debug code into a template file and call a page with it:
      $to = array('me@example.com'); $subject = 'Wiremail-SMTP Test ' . date('H:i:s') . ' äöü ÄÖÜ ß'; $mail = wireMail(); if($mail->className != 'WireMailSmtp') { echo "<p>Couldn't get the right WireMail-Module (WireMailSmtp). found: {$mail->className}</p>"; } else { $mail->from = '--INSERT YOUR SENDER ADDRESS HERE --'; // <--- !!!! $mail->to($to); $mail->subject($subject); $mail->sendSingle(true); $mail->body("Titel\n\ntext text TEXT text text\n"); $mail->bodyHTML("<h1>Titel</h1><p>text text <strong>TEXT</strong> text text</p>"); $dump = $mail->debugSend(1); } So, in short, instead of using $mail->send(), use $mail->debugSend(1) to get output on a frontend testpage.
      The output is PRE formatted and contains the areas: SETTINGS, RESULT, ERRORS and a complete debuglog of the server connection, like this one:
       
      Following are a ...


      List of all options and features


      testConnection () - returns true on success, false on failures


      sendSingle ( true | false ) - default is false

      sendBulk ( true | false ) - default is false, Set this to true if you have lots of recipients (50+)


      to ($recipients) - one emailaddress or array with multiple emailaddresses

      cc ($recipients) - only available with mode sendSingle, one emailaddress or array with multiple emailaddresses

      bcc ($recipients) - one emailaddress or array with multiple emailaddresses

       
      from = 'person@example.com' - emailaddress, can be set in module config (called Sender Emailaddress) but it can be overwritten here

      fromName = 'Name Surname' - optional, can be set in module config (called Sender Name) but it can be overwritten here


      priority (3) - 1 = Highest | 2 = High | 3 = Normal | 4 = Low | 5 = Lowest

      dispositionNotification () or notification () - request a Disposition Notification


      subject ($subject) - subject of the message

      body ($textBody) - use this one alone to create and send plainText emailmessages

      bodyHTML ($htmlBody) - use this to create a Multipart Alternative Emailmessage (containing a HTML-Part and a Plaintext-Part as fallback)

      addSignature ( true | false ) - the default-behave is selectable in config screen, this can be overridden here
      (only available if a signature is defined in the config screen)

      attachment ($filename, $alternativeBasename = "") - add attachment file, optionally alternative basename


      send () - send the message(s) and return number of successful sent messages


      debugSend(1) - returns and / or outputs a (pre formatted) dump that contains the areas: SETTINGS, RESULT, ERRORS and a complete debuglog of the server connection. (See above the example code under ADVANCED DEBUG METHOD for further instructions!)


      getResult () - returns a dump (array) with all recipients (to, cc, bcc) and settings you have selected with the message, the message subject and body, and lists of successfull addresses and failed addresses,


      logActivity ($logmessage) - you may log success if you want

      logError ($logmessage) - you may log warnings, too. - Errors are logged automaticaly
       
       
      useSentLog (true | false) - intended for usage with e.g. third party newsletter modules - tells the send() method to make usage of the sentLog-methods - the following three sentLog methods are hookable, e.g. if you don't want log into files you may provide your own storage, or add additional functionality here

      sentLogReset ()  - starts a new LogSession - Best usage would be interactively once when setting up a new Newsletter

      sentLogGet ()  - is called automaticly within the send() method - returns an array containing all previously used emailaddresses

      sentLogAdd ($emailaddress)  - is called automaticly within the send() method

      Sanitizer EasySlugger
      Allows the use of the EasySlugger library as Sanitizer methods.
      Installation
      Install the Sanitizer EasySlugger module.
      Usage
      The module adds four new sanitizer methods.
      slugger($string, $options)
      Similar to $sanitizer->pageName() - I'm not sure if there are any advantages over that method. Included because it is one of the methods offered by EasySlugger.
      $slug = $sanitizer->slugger('Lorem Ipsum'); // Result: lorem-ipsum utf8Slugger($string, $options)
      Creates slugs from non-latin alphabets.
      $slug = $sanitizer->utf8Slugger('这个用汉语怎么说'); // Result: zhe-ge-yong-han-yu-zen-me-shuo seoSlugger($string, $options)
      Augments the string before turning it into a slug. The conversions are related to numbers, currencies, email addresses and other common symbols.
      $slug = $sanitizer->seoSlugger('The price is $5.99'); // Result: the-price-is-5-dollars-99-cents See the EasySlugger readme for some more examples.
      seoUtf8Slugger($string, $options)
      A combination of utf8Slugger() and seoSlugger().
      $slug = $sanitizer->seoUtf8Slugger('价钱是 $5.99'); // Result: jia-qian-shi-5-dollars-99-cents $options argument
      Each of the methods can take an $options array as a second argument.
      separator (string): the character that separates words in the slug. Default: - unique (bool): Determines whether a random suffix is added at the end of the slug. Default: false $slug = $sanitizer->utf8Slugger('这个用汉语怎么说', ['separator' => '_', 'unique' => true]); // Result: zhe_ge_yong_han_yu_zen_me_shuo_3ad66c4

      If you've ever needed to insert links to a large number of files within CKEditor you may have found that the standard PW link modal is a somewhat slow way to do it.
      This module provides a quicker way to insert links to files on the page being edited. You can insert a link to an individual file, or insert an unordered list of links to all files on the page with a single click.
      CKEditor Link Files
      Adds a menu to CKEditor to allow the quick insertion of links to files on the page being edited.

      Features
      Hover a menu item to see the "Description" of the corresponding file (if present). Click a menu item to insert a link to the corresponding file at the current cursor position. The filename is used as the link text. If you Alt-click a menu item the file description is used as the link text (with fallback to filename if no description entered). If text is currently selected in the editor then the selected text is used as the link text. Click "* Insert links to all files *" to insert an unordered list of links to all files on the page. Also works with the Alt-click option. Menu is built via AJAX so newly uploaded files are included in the menu without the page needing to be saved. However, descriptions are not available for newly uploaded files until the page is saved. There is an option in the module config to include files from Repeater fields in the edited page. Nested Repeater fields (files inside a Repeater inside another Repeater) are not supported. Installation
      Install the CKEditor Link Files module.
      For any CKEditor field where you want the "Insert link to file" dropdown menu to appear in the CKEditor toolbar, visit the field settings and add "LinkFilesMenu" to the "CKEditor Toolbar" settings field.
