HannaCodeDialog

Recommended Posts

@MilenKo, it's not possible to have a required field in the dialog because the dialog form is not submitted anywhere for ProcessWire validation - the field values are just captured via Javascript when the dialog is closed. You should check for empty field values in the code for your Hanna tag.

Incidentally, this is true for any "required" field anywhere in PW because nothing is ever really required - the user can simply abandon the edit process if they want and leave unfilled required fields, so you always need to check that fields are actually populated before doing anything with their value.

@Robin S Thanks for your clarification. I was afraid you would say so, but was just thinking if it would be possible for me to modify the dialogue files and have an extra option added like the other attribute options - something like:

attribute__options=Option1|Option2 but with some extra logic:

attribute__requirements=required or similar.

My idea is that from the dropdown menu, the user is provided a choice of multiple blocks and once one is selected, the dialogue opens up and can intercept an eventual requirement set thorugh the module. Once the user has finished and press OK, if he double clicks on the HC he is still seeing the same code so technically it would be difficult for the user to change the text etc. and is presented a nice "reminder" of an empty attribute or else.

On the other thought, the present functionality might be a better option for me as I am allowing a user to choose a news tab category (1 out of 10) so he can leave 1 empty, 2 empty and then add 3, 4 etc. 

Will see how it would be completted to fit the requirements and avoid any errors as presently I am grouping all the attributes to an array, then have to clean the empty values, then to reorder and then to apply it. But hey, it works and it was super easy for my 8 years old boy I've tested with to add the block, pick categories, limit the number of pages shown etc. GREAT THANK YOU FOR THE EFFORTS AND MODULE!

Btw, is it possible to set the width/height of the dialogue box (width/height) as presently I have about 10 drop-down boxes for categories plus some other limiters to show a specific page count on the block so the scrolling is not very convenient? Maybe I can make the dialogue wider through some options or else? I mean if it is possible to have the options per tag, not by default?

No, that isn't possible in this module - the dialog width and height in the module config applies globally to all Hanna tags.

@Robin S Thank you for your info. Would it be possible to have an option to set the width and height of the dialogue for all Hanna Tags which would make my options visible better or I would have to set the dimensions by editing the module files?

As per my previous reply and the module readme there are config options for dialog width and height.

Or maybe I don't understand your question.

Oh, @Robin S my bad. I don't know how but I've missed to check the module configuration page and was looking at the tag options again. It works perfectly now and I can increase the size from there as most of my tags would require bigger window. Thank you again for the help.

v0.2.1 released.

This is a fairly major update in that there has been quite a bit of refactoring. Please be alert for and report any issues. ProcessWire >= v3.0.0 is now required.

This release adds a new hookable HannaCodeDialog::buildForm() method that lets you build the dialog form in the hook rather than setting inputfield options as pseudo-attributes in the Hanna Code tag settings.

From the readme...

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);

    }

});

      MarkupMenu is a markup module for generating menu trees. When provided a root page as a starting point, it generates a navigation tree (by default as a HTML "<ul>" element wrapped by a "<nav>" element) from that point onwards. If you've also provided it with current (active) page, the menu will be rendered accordingly, with current item highlighted and items rendered up to that item and its children (unless you disable the "collapsed" option, in which case the full page tree will be rendered instead).
      Modules directory: https://modules.processwire.com/modules/markup-menu/ GitHub repository: https://github.com/teppokoivula/MarkupMenu Usage
      As a markup module, MarkupMenu is intended for front-end use, but you can of course use it in a module as well. Typically you'll only need the render() method, which takes an array of options as its only argument:
      echo $modules->get('MarkupMenu')->render([ 'root_page' => $pages->get(1), 'current_page' => $page, ]); Note: if you omit root_page, site root page is used by default. If you omit current_page, the menu will be rendered, but current (active) page won't be highlighted etc.
      A slightly more complex example, based on what I'm using on one of my own sites to render a (single-level) top menu:
      echo $modules->get('MarkupMenu')->render([ 'current_page' => $page, 'templates' => [ 'nav' => '<nav class="{classes} menu--{menu_class_modifier}" aria-label="{aria_label}">%s</nav>', 'item_current' => '<a class="menu__item menu__item--current" href="{item.url}" tabindex="0" aria-label="Current page: {item.title}">{item.title}</a>', ], 'placeholders' => [ 'menu_class_modifier' => 'top', 'aria_label' => 'Main navigation', ], 'include' => [ 'root_page' => true, ], 'exclude' => [ 'level_greater_than' => 1, ], ]); Note: some things you see above may not be entirely sensible, such as the use of {menu_class_modifier} and {aria_label} placeholders. On the actual site the "nav" template is defined in site config, so I can define just these parts on a case-by-case basis while actual nav markup is maintained in one place.
      Please check out the README file for available render options. I'd very much prefer not to keep this list up to date in multiple places. Basically there are settings for defining "templates" for different parts of the menu (list, item, etc.), include array for defining rules for including in the menu and exclude array for the opposite effect, classes and placeholders arrays for overriding default classes and injecting custom placeholders, etc. 🙂
      MarkupMenu vs. MarkupSimpleNavigation
      TL;DR: this is another take on the same concept. There are many similarities, but also some differences – especially when it comes to the supported options and syntax. If you're currently using MarkupSimpleNavigation then there's probably no reason to switch over.
      I'd be surprised if anyone didn't draw lines between this module and Soma's awesome MarkupSimpleNavigation. Simply put, I've been using MSN (...) for a number of years, and it's been great – but there have been some smallish issues with it, particularly with the markup generation part, and it's also doing some things in a way that just doesn't work for me – the xtemplates thing being one of these. In many ways it's less about features, and more about style.
      In MarkupMenu I've tried to correct these little hiccups, modernise the default markup, and allow for more flexibility with placeholder variables and additional / different options. MarkupMenu was built for ProcessWire 3.0.112+ and PHP 7.1+, it's installable with Composer, and I have a few additional ideas (such as conditional placeholders) on my todo list.
      One smallish and rather specific difference is that MarkupMenu supports overriding default options via $config->MarkupMenu. I find myself redefining the default markup for every site, which until now meant that each site has a wrapper function for MarkupSimpleNavigation (to avoid code / config repetition), and this way I've been able to omit that 🙂
      Requirements
      ProcessWire >= 3.0.112 PHP >= 7.1.0 If you're working on an earlier version of ProcessWire or PHP, use MarkupSimpleNavigation instead.

      Repeater Images
      Adds options to modify Repeater fields to make them convenient for "page-per-image" usage. Using a page-per-image approach allows for additional fields to be associated with each image, to record things such as photographer, date, license, links, etc.
      When Repeater Images is enabled for a Repeater field the module changes the appearance of the Repeater inputfield to be similar (but not identical) to an Images field. The collapsed view shows a thumbnail for each Repeater item, and items can be expanded for field editing.
      Screencast

      Installation
      Install the Repeater Images module.
      Setup
      Create an image field to use in the Repeater field. Recommended settings for the image field are "Maximum files allowed" set to 1 and "Formatted value" set to "Single item (null if empty)". Create a Repeater field. Add the image field to the Repeater. If you want additional fields in the Repeater create and add these also. Repeater Images configuration
      Tick the "Activate Repeater Images for this Repeater field" checkbox. In the "Image field within Repeater" dropdown select the single image field. You must save the Repeater field settings to see any newly added Image fields in the dropdown. Adjust the image thumbnail height if you want (unlike the core Images field there is no slider to change thumbnail height within Page Edit). Note: the depth option for Repeater fields is not compatible with the Repeater Images module.
      Image uploads feature
      There is a checkbox to activate image uploads. This feature allows users to quickly and easily add images to the Repeater Images field by uploading them to an adjacent "upload" field.
      To use this feature you must add the image field selected in the Repeater Images config to the template of the page containing the Repeater Images field - immediately above or below the Repeater Images field would be a good position.
      It's recommended to set the label for this field in template context to "Upload images" or similar, and set the visibility of the field to "Closed" so that it takes up less room when it's not being used. Note that when you drag images to a closed Images field it will automatically open. You don't need to worry about the "Maximum files allowed" setting because the Repeater Images module overrides this for the upload field.
      New Repeater items will be created from the images uploaded to the upload field when the page is saved. The user can add descriptions and tags to the images while they are still in the upload field and these will be retained in the Repeater items. Images are automatically deleted from the upload field when the page is saved.
      Tips
      The "Use accordion mode?" option in the Repeater field settings is useful for keeping the inputfield compact, with only one image item open for editing at a time. The "Repeater item labels" setting determines what is shown in the thumbnail overlay on hover. Example for an image field named "image": {image.basename} ({image.width}x{image.height})

      Hello There Guys.

      I am in the process of getting into making my first modules for PW and i had a question for you PHP and PW gurus in here.

      I was wondering how i could use an external library, lets say TwitterOAuth in my PW module.
      Link to library
      https://twitteroauth.com/

      Would the code below be correct or how would i go about this:
      <?PHP namespace ProcessWire; /* load the TwitterOAuth library from my Module folder */ require "twitteroauth/autoload.php"; use Abraham\TwitterOAuth\TwitterOAuth; class EyeTwitter extends WireData,TwitterOAuth implements Module { /* vars */ protected $twConnection; /* extend parent TwitterOAuth contructor $connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, $access_token, $access_token_secret); */ public function myTwitterConnection ($consumer_key, $consumer_secret, $access_token, $access_token_secret) { /* save the connection for use later */ $this->twConnection = TwitterOAuth::__construct($consumer_key, $consumer_secret, $access_token, $access_token_secret); } } ?> Am i on the right trail here or i am barking up the wrong tree?
      I don´t need a complete solution, i just wonder if i am including the external library the right way.
      If not, then give me a few hint´s and i will figure it out.

      Thanks a bunch.

      Hello,
      this module can publish content of a Processwire page on a Facebook page, triggered by saving the Processwire page.
      To set it up, configure the module with a Facebook app ID, secret and a Page ID. Following is additional configuration on Facebook for developers:
      Minimum Required Facebook App configuration:
      on Settings -> Basics, provide the App Domains, provide the Site URL, on Settings -> Advanced, set the API version (has been tested up to v3.3), add Product: Facebook Login, on Facebook Login -> Settings, set Client OAuth Login: Yes, set Web OAuth Login: Yes, set Enforce HTTPS: Yes, add "http://www.example.com/processwire/page/" to field Valid OAuth Redirect URIs. This module is configurable as follows:
      Templates: posts can take place only for pages with the defined templates. On/Off switch: specify a checkbox field that will not allow the post if checked. Specify a message and/or an image for the post.
      Usage
      edit the desired PW page and save; it will post right after the initial Facebook log in and permission granting. After that, an access token is kept.
       
      Download
      PW module directory: http://modules.processwire.com/modules/auto-fb-post/ Github: https://github.com/kastrind/AutoFbPost   Note: Facebook SDK for PHP is utilized.

      FieldtypeRuntimeMarkup and InputfieldRuntimeMarkup
       
      Modules Directory: http://modules.processwire.com/modules/fieldtype-runtime-markup/
      GitHub: https://github.com/kongondo/FieldtypeRuntimeMarkup
      As of 11 May 2019 ProcessWire versions earlier than 3.x are not supported
      This module allows for custom markup to be dynamically (PHP) generated and output within a page's edit screen (in Admin).
       
      The value for the fieldtype is generated at runtime. No data is saved in the database. The accompanying InputfieldRuntimeMarkup is only used to render/display the markup in the page edit screen.
       
      The field's value is accessible from the ProcessWire API in the frontend like any other field, i.e. it has access to $page and $pages.
       
      The module was commissioned/sponsored by @Valan. Although there's certainly other ways to achieve what this module does, it offers a dynamic and flexible alternative to generating your own markup in a page's edit screen whilst also allowing access to that markup in the frontend. Thanks Valan!
       
      Warning/Consideration
      Although access to ProcessWire's Fields' admin pages is only available to Superusers, this Fieldtype will evaluate and run the custom PHP Code entered and saved in the field's settings (Details tab). Utmost care should therefore be taken in making sure your code does not perform any CRUD operations!! (unless of course that's intentional) The value for this fieldtype is generated at runtime and thus no data is stored in the database. This means that you cannot directly query a RuntimeMarkup field from $pages->find(). Usage and API
       
      Backend
      Enter your custom PHP snippet in the Details tab of your field (it is RECOMMENDED though that you use wireRenderFile() instead. See example below). Your code can be as simple or as complicated as you want as long as in the end you return a value that is not an array or an object or anything other than a string/integer.
       
      FieldtypeRuntimeMarkup has access to $page (the current page being edited/viewed) and $pages. 
       
      A very simple example.
      return 'Hello'; Simple example.
      return $page->title; Simple example with markup.
      return '<h2>' . $page->title . '</h2>'; Another simple example with markup.
      $out = '<h1>hello '; $out .= $page->title; $out .= '</h1>'; return $out; A more advanced example.
      $p = $pages->get('/about-us/')->child('sort=random'); return '<p>' . $p->title . '</p>'; An even more complex example.
      $str =''; if($page->name == 'about-us') { $p = $page->children->last(); $str = "<h2><a href='{$p->url}'>{$p->title}</a></h2>"; } else { $str = "<h2><a href='{$page->url}'>{$page->title}</a></h2>"; } return $str; Rather than type your code directly in the Details tab of the field, it is highly recommended that you placed all your code in an external file and call that file using the core wireRenderFile() method. Taking this approach means you will be able to edit your code in your favourite text editor. It also means you will be able to type more text without having to scroll. Editing the file is also easier than editing the field. To use this approach, simply do:
      return wireRenderFile('name-of-file');// file will be in /site/templates/ If using ProcessWire 3.x, you will need to use namespace as follows:
      return ProcessWire\wireRenderFile('name-of-file'); How to access the value of RuntimeMarkup in the frontend (our field is called 'runtime_markup')
       
      Access the field on the current page (just like any other field)
      echo $page->runtime_markup; Access the field on another page
      echo $pages->get('/about-us/')->runtime_markup; Screenshots
       
      Backend
