Newsletter Subscription

Recommended Posts

This module allows users to subscribe and unsubscribe to a newsletter, it doesn't handle newsletter creation and delivery (I use a foreign service for this).

There is one method to subscribe (by using a form) and there are two methods to unsubscribe (by using a form or by providing a link in the newsletter). Furthermore you can notify any person e.g. an administator via email when an user has subscribed/unsubscribed.

For detailed information have a look at Github.

I have a question about this module, I've followed the installation steps:
— created first_name and last_name fields
— added those fields to user template
 
Then I created a newsletter template in which I called the module as mentioned:
 

$options = array (
  'markup' => array(
    'InputfieldSelect' => array(
      'item' => "{out}"
    )
  ),
  'classes' => array(
    'form' => 'form  form__super-special-class',
    'InputfieldRadios' => array(
      'item' => 'form__item--options'
    )
  ),
  'prependMarkup' => "<div>{$page->prepend_markup}</div>",
  'appendMarkup' => "<p>{$page->append_markup}</p>"
);
 
echo $modules->get('NewsletterSubscription')->render($options);

Finally I created a newsletter page.
I can then open the page and subscribe, I receive the confirmation email but when I click on the link I get those errors (even though I appear in the users panel in pw): 
 

Error: Exception: Method User::setAndSave does not exist or is not callable in this context (in /home/tenutaxyit/www/wire/core/Wire.php line 350)

Your ProcessWire version is not new enough. setAndSave was introduced with version 2.6.9, this was one of the reasons why I set the compatibility for this module to 2.7.

Hi,

i followed the installation process and integrated the form in my page.

If i click on Send then i am getting following error:

Error: Call to undefined method WireInput::text() (line 367 of /xxxxxxxxx/site/modules/NewsletterSubscription/NewsletterSubscription.module)

This error message was shown because you are logged in as a Superuser. Error has been logged.

 

What can i do?

Hi, sorry for taking that long to answer. 

I made a silly mistake that slipped through regarding sanitizing input. It's fixed. Thanks for reporting.

You're able to send an email to any service you want to after successful subscription / unsubscription.  Calling an api endpoint isn't implemented yet (there are too much different services). If you miss a hookable function just let me know, I'll go ahead and add it. If everything works out (if the customer agrees to use ProcessWire), perhaps I'll soon be given an opportunity to implement a connection to mailchimp by myself.

Could I use a plain html form with this module, instead of using the render() tag? I want to have more control over style etc. without having to use the complicated classes and markup overwrite methods.

What would I have to add to a plain html form to let the module take care of processing the data?

My html output of the tag looks like this:

Spoiler

<form id="subscribe-form" class=" form InputfieldForm" name="subscribe-form" method="post" action="./" data-colspacing="1">
	<div class='form__item form__item--fullname' id='wrap_Inputfield_fullname'>

		<label class='form__item--label' for='Inputfield_fullname'>Full name</label><input id="Inputfield_fullname" class="InputfieldMaxWidth" name="fullname" type="text" maxlength="2048" />
	</div>
	<div class='form__item form__item--email field--required' id='wrap_Inputfield_email'>

		<label class='form__item--label' for='Inputfield_email'>E-Mail Address</label><input id="Inputfield_email" name="email" class="FieldtypeEmail required" type="email" size="70" maxlength="255" />
	</div>
	<div class='form__item form__item--submit' id='wrap_Inputfield_submit'>
<button id="Inputfield_submit" class="button" name="submit" value="Send" type="submit"><span class='ui-button-text'>Send</span></button>
	</div>
<input type='hidden' name='TOKEN1009186866X1485168757' value='qqpdZc2cDDarCajU/Ns/VlbjtZtavbjX' class='_post_token' /></form></div>

 

Could I just use a restyled version of this form? Minus the input with the TOKEN# I guess and plus some PHP magic?

Another issue:

The 'success' message replaces the form, but not the text I had added above the form. How can I make that added text disappear/go display:none along with the form?

If I could use plain html, I could just include the intro within the form tag.

hi, it's not possible (out of the box) to use a plain form instead of the render() tag. The processing of the form includes several error checks and a lot of additional logic. I solved it this way because my experience has shown that it's really difficult to support plain html. Most users break the form which leads to increased overhead. I'm not a fan of generated content therefore I added all possible options to customize the output. 

How did you add the content above the form? Do you use the option `prependMarkup`? If the content above is still there after submitting the form, this is ProcessWire Core behaviour I don't want to change. Just use `display: none` to hide the content (there should be a parent element containing a class which indicates that the form has been submitted successfully. If not, please let me know,  I'll add such a class).

Thanks justb3a. I will use the module as is.

1. To change the subject line of the emails sent to the user I had to edit the the module file. Is that correct or did I miss an edit option in the admin area somewhere?

2. There are ways to turn labels into placeholders via CSS...

https://css-tricks.com/float-labels-css/

...but they require <label> to come after <input> or/and have 'required' in the input tag. This would also require editing the module - and I can't figure out where/how.

 @modifiedcontent Actually it's pretty funny you're asking this right now. Some hours ago I opened a feature request regarding this because at the moment it's not possible to swap the order without using regex.

The subject is translatable. So even if the page is not multi-lingual, you can overwrite the subject this way.

@justb3a, I have started researching how to build forms - with generous help from fbg13 - because my employer/client wants more fields in the newsletter signup.

Wouldn't it be better to store newsletter subscribers under a new page instead of in users/access management?

I guess roles etc. would not be available if you have a custom members/subscribers table as a page? That could be a problem if the signup is for a community/social network, but not so much for a basic newsletter.

Btw, I used a SuperLabels jquery plugin to turn your labels into pseudo-placeholders. It's actually a nice-looking solution.

The module offers the possibility to add as many fields as you want. Why not using this in-build functionality?

Sure, you can store newsletter subscribers under another page or inside of a repeater or in a pagetable or ... There are a lot of options. For my use case it was the easiest solution to store them as a user with a specific role. Users are pages as well! If you want to change this behaviour, you need to rewrite a lot.

I wrote a few lines of JavaScript myself to achieve this. This project has no jQuery dependency. Furthermore I do not swap the order, I just need to know, whether the input is empty, focused or filled to be able to set the desired styling. See it in action!

@justb3a thanks for providing this module!

Before starting to use it to collect new subscribers, I had to import a list of existing newsletter subscribers from our old system.

The list is just a text file with one email address per line.

The amazing BCE didn't help in this case because PW users - while still pages - are somewhat special.

I came up with a little script which can be invoked from a browser window:

<?php namespace ProcessWire;

include("../index.php"); // bootstrap PW

/*
 * import newsletter subscribers
 * from a file 'subscribers.txt'
*/

$file = fopen("subscribers.txt", "r");

$i = 0;

while(!feof($file)) {
    $line = fgets($file);
    if($line == '') {
        continue;
    }
    $email = $sanitizer->email($line);
    if($email == '') {
        echo 'misformed email rejected: ' . $line . '<br>';
        continue;
    }
    $name = 'zzz-import-' . sprintf('%05d', $i);

    $u = new User();
    $u->of(false);
    $u->name = $name;
    $u->email = $email;
    $u->addRole('newsletter');
    $u->save();

    $log->save('newsletter', "User {$u->name} has been successfully subscribed with email {$u->email}");
    $i++;
}

fclose($file);

echo "<br>{$i} subscribers imported.<br>";

I am not sure if a lot of other poeple need something like that as well - if so, maybe adding an "import" feature for the NewsletterSubscription module would make sense.

Thanks for considering and greetings from the neighborhood!

Hey there,

 

Great module. Thanks for the functionality.

I am using checkboxes of a multi-lang page reference field in the subscription form and I was wondering if multi-lang fields are supported by default, because the checkboxes are not translated. The Label of the field is translated correctly, but not the rest.

Thanks for some information.

You can define an unsubscribe messge In the module config (E-Mail Messages section), for example:
 

To unsubscribe from this newsletter please follow this link:
%link%

I wonder how the module can be made GDPR conform.
As far as I can see only the unsubscription proccedure needs some tweaks in the private function validateUnsubscribeToken():

$this->users->delete($user);
$this->log->save('messages', "User has been successfully deleted with id `{$user->id}`.");

First line: Can anyone confirm, that the whole entry is fully deleted and cannot be restored? (At the moment I have no testsystem to check it)
Second line: Switching the log from email to id, as the id is no personal data. But the id could be used as unique identifyer for deleted users when syncing with / exporting to other systems . Maybe adding a timestamp also would be good.

Another point to consider is neutralizing the optional email notifications to the admin.
Any other issue?

Hello @justb3a,

first of thank you for this and your other modules. 😃

I wanted to ask if it is possible for subscribers to let them change their preferences after the initial subscription? In my use-case I want to build a website, where subscribers can choose different newsletter channels via checkboxes (page field) on the initial subscription. This part is working fine, but after the subscription it is only possible for subscribers to change their preferences, if they unsubscribe and then re-subscribe.

Could I provide a link with the ID or token and maybe a timestamp in the subscription email to a custom front-end form, where they can change and save their settings? It should be a verified and save address, so that no other user could guess the url and change settings of other users.

I would be happy about some inspiration. 😉

Regards, Andreas

      After some years with a website working perfectly, Page Clone started to display some strange behaviour:
      1. When cloning some pages, it takes forever. The waiting icon is displayed but the page never appears. Only after I refresh the tree page, the new page appears:

      2. The other thing is that some pages can't be copied. The pages have the same templates but the users are able to copy some and other don't. It gives this error:

      (the URL is .../page/clone/?id=76376&login=1)
      Does someone have a clue why this is happening. I can't find any real difference between the pages that I'm trying to copy.
      One more thing: If the user is a super user, he's able to copy every page without problems.
      I think both errors might be related. Thanks!

      ---- 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"):

      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
