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

Hey @justb3a I can tell you've done an interesting module and even though I did not test it yet, I could see it already fitting to my needs. Since I see that the module development is discontinued, does anyone know of existing issues for some basic user subscription? I am building a profile for a tech support company and the client would like to collect client's name, email and eventually phone number in order to broadcast occasionally some promotions, discounts, new services etc. Since the client is located in North America, it won't be that much of a problem if GDPR is not fully operational (as far as I understood from the earlier questions), however I would see how to make it work so that any European client does not fall through and complain of non-EU-GDPR-compliant website 😉

So any known issues I should be aware before I implement the module?

      PageImage Manipulator, API for version 1 & 2

      The Page Image Manipulator is a module that let you in a first place do ImageManipulations with your PageImages. - And in a second place there is the possibility to let it work on any imagefile that exists in your servers filesystem, regardless if it is a 'known PW-image'.

      The Page Image Manipulator is a Toolbox for Users and Moduledevelopers. It is written to be as close to the Core ImageSizer as possible. Besides the GD-filterfunctions it contains resize, crop, canvas, rotate, flip, sharpen, unsharpMask and 3 watermark methods.



      How does it work?

      You can enter the ImageManipulator by calling the method pim2Load(). After that you can chain together how many actions in what ever order you like. If your manipulation is finished, you call pimSave() to write the memory Image into a diskfile. pimSave() returns the PageImage-Object of the new written file so we are able to further use any known PW-image property or method. This way it integrates best into the ProcessWire flow.

      The three examples above put out the same visual result: a grayscale image with a width of 240px. Only the filenames will slightly differ.

      You have to define a name-prefix that you pass with the pimLoad() method. If the file with that prefix already exists, all operations are skipped and only the desired PageImage-Object gets returned by pimSave(). If you want to force recreation of the file, you can pass as second param a boolean true: pim2Load('myPrefix', true).

      You may also want to get rid of all variations at once? Than you can call $pageimage->pim2Load('myPrefix')->removePimVariations()!

      A complete list of all methods and actions are at the end of this post.

      Page Image Manipulator - Methods

      * pimLoad  or  pim2Load, depends on the version you use!

      pimLoad($prefix, $param2=optional, $param3=optional)
      param 1: $prefix - (string) = mandatory! param 2: mixed, $forceRecreation or $options param 3: mixed, $forceRecreation or $options return: pim - (class handle) $options - (array) default is empty, see the next method for a list of valid options! $forceRecreation - (bool) default is false It check if the desired image variation exists, if not or if forceRecreation is set to true, it prepares all settings to get ready for image manipulation
      -------------------------------------------------------------------

      * setOptions

      setOptions(array $options)
      param: $options - (array) default is empty return: pim - (class handle) Takes an array with any number valid options / properties and set them by replacing the class-defaults and / or the global config defaults optionally set in the site/config.php under imageSizerOptions or imageManipulatorOptions.

      valid options are:
      quality = 1 - 100 (integer) upscaling = true | false (boolean) cropping = true | false (boolean) autoRotation =true | false (boolean) sharpening = 'none' | 'soft' | 'medium' | 'strong' (string) bgcolor = (array) css rgb or css rgba, first three values are integer 0-255 and optional 4 value is float 0-1, - default is array(255,255,255,0) thumbnailColorizeCustom = (array) rgb with values for colorize, integer -255 - 255 (this can be used to set a custom color when working together with Thumbnails-Module)
        outputFormat = 'gif' | 'jpg' | 'png' (Attention: outputFormat cannot be specified as global option in $config->imageManipulatorOptions!) set {singleOption} ($value)
      For every valid option there is also a single method that you can call, like setQuality(90), setUpscaling(false), etc.
      -------------------------------------------------------------------

      * pimSave

      pimSave()
      return: PageImage-Object If a new image is hold in memory, it saves the current content into a diskfile, according to the settings of filename, imagetype, targetFilename and outputFormat. Returns a PageImage-Object!
      -------------------------------------------------------------------

      * release

      release()
      return: void (nothing) if you, for what ever reason, first load image into memory but than do not save it, you should call release() to do the dishes! 😉 If you use pimSave() to leave the ImageManipulator, release() is called automatically.
      -------------------------------------------------------------------

      * getOptions

      getOptions()
      return: associative array with all final option values example:
      ["autoRotation"] bool(true) ["upscaling"] bool(false) ["cropping"] bool(true) ["quality"] int(90) ["sharpening"] string(6) "medium" ["targetFilename"] string(96) "/htdocs/site/assets/files/1124/pim_prefix_filename.jpg" ["outputFormat"] string(3) "jpg" get {singleOption} ()
      For every valid option there is also a single method that you can call, like getQuality(), getUpscaling(), etc. See method setOptions for a list of valid options!
      -------------------------------------------------------------------

      * getImageInfo

      getImageInfo()
      return: associative array with useful informations of source imagefile example:
      ["type"] string(3) "jpg" ["imageType"] int(2) ["mimetype"] string(10) "image/jpeg" ["width"] int(500) ["height"] int(331) ["landscape"] bool(true) ["ratio"] float(1.5105740181269) ["bits"] int(8) ["channels"] int(3) ["colspace"] string(9) "DeviceRGB" -------------------------------------------------------------------

      * getPimVariations

      getPimVariations()
      return: array of Pageimages Collect all pimVariations of this Pageimage as a Pageimages array of Pageimage objects. All variations created by the core ImageSizer are not included in the collection.
      -------------------------------------------------------------------

      * removePimVariations

      removePimVariations()
      return: pim - (class handle) Removes all image variations that was created using the PIM, all variations that are created by the core ImageSizer are left untouched!
      -------------------------------------------------------------------
      * width

      width($dst_width, $sharpen_mode=null)
      param: $dst_width - (integer) param: $auto_sharpen - (boolean) default is true was deleted with version 0.0.8, - sorry for breaking compatibility param: $sharpen_mode - (string) possible: 'none' | 'soft' | 'medium' | 'strong', default is 'soft' return: pim - (class handle) Is a call to resize where you prioritize the width, like with pageimage. Additionally, after resizing, an automatic sharpening can be done with one of the three modes.
      -------------------------------------------------------------------

      * height

      height($dst_height, $sharpen_mode=null)
      param: $dst_height - (integer) param: $auto_sharpen - (boolean) default is true was deleted with version 0.0.8, - sorry for breaking compatibility param: $sharpen_mode - (string) possible: 'none' | 'soft' | 'medium' | 'strong', default is 'soft' return: pim - (class handle) Is a call to resize where you prioritize the height, like with pageimage. Additionally, after resizing, an automatic sharpening can be done with one of the three modes.
      -------------------------------------------------------------------

      * resize

      resize($dst_width=0, $dst_height=0, $sharpen_mode=null)
      param: $dst_width - (integer) default is 0 param: $dst_height - (integer) default is 0 param: $auto_sharpen - (boolean) default is true was deleted with version 0.0.8, - sorry for breaking compatibility param: $sharpen_mode - (string) possible: 'none' | 'soft' | 'medium' | 'strong', default is 'soft' return: pim - (class handle) Is a call to resize where you have to set width and / or height, like with pageimage size(). Additionally, after resizing, an automatic sharpening can be done with one of the three modes.
      -------------------------------------------------------------------

      * stepResize

      stepResize($dst_width=0, $dst_height=0)
      param: $dst_width - (integer) default is 0 param: $dst_height - (integer) default is 0 return: pim - (class handle) this performs a resizing but with multiple little steps, each step followed by a soft sharpening. That way you can get better result of sharpened images.
      -------------------------------------------------------------------

      * sharpen

      sharpen($mode='soft')
      param: $mode - (string) possible values 'none' | 'soft'| 'medium'| 'strong' return: pim - (class handle) Applys sharpening to the current memory image. You can call it with one of the three predefined pattern, or you can pass an array with your own pattern.
      -------------------------------------------------------------------

      * unsharpMask

      unsharpMask($amount, $radius, $threshold)
      param: $amount - (integer) 0 - 500, default is 100 param: $radius - (float) 0.1 - 50, default is 0.5 param: $threshold - (integer) 0 - 255, default is 3 return: pim - (class handle) Applys sharpening to the current memory image like the equal named filter in photoshop.
      Credit for the used unsharp mask algorithm goes to Torstein Hønsi who has created the function back in 2003.
      -------------------------------------------------------------------

      * smooth

      smooth($level=127)
      param: $level - (integer) 1 - 255, default is 127 return: pim - (class handle) Smooth is the opposite of sharpen. You can define how strong it should be applied, 1 is low and 255 is strong.
      -------------------------------------------------------------------

      * blur

      blur()
      return: pim - (class handle) Blur is like smooth, but cannot called with a value. It seems to be similar like a result of smooth with a value greater than 200.
      -------------------------------------------------------------------

      * crop

      crop($pos_x, $pos_y, $width, $height)
      param: $pos_x - (integer) start position left param: $pos_y - (integer) start position top param: $width - (integer) horizontal length of desired image part param: $height - (integer) vertical length of desired image part return: pim - (class handle) This method cut out a part of the memory image.
      -------------------------------------------------------------------

      * canvas

      canvas($width, $height, $bgcolor, $position, $padding)
      param: $width = mixed, associative array with options or integer, - mandatory! param: $height = integer, - mandatory if $width is integer! param: $bgcolor = array with rgb or rgba, - default is array(255, 255, 255, 0) param: $position = one out of north, northwest, center, etc, - default is center param: $padding = integer as percent of canvas length, - default is 0 return: pim - (class handle) This method creates a canvas according to the given width and height and position the memory image onto it.
      You can pass an associative options array as the first and only param. With it you have to set width and height and optionally any other valid param. Or you have to set at least width and height as integers.
      Hint: If you want use transparency with rgba and your sourceImage isn't of type PNG, you have to define 'png' as outputFormat with your initially options array or, for example, like this: $image->pimLoad('prefix')->setOutputFormat('png')->canvas(300, 300, array(210,233,238,0.5), 'c', 5)->pimSave()
      -------------------------------------------------------------------

      * flip

      flip($vertical=false)
      param: $vertical - (boolean) default is false return: pim - (class handle) This flips the image horizontal by default. (mirroring)
      If the boolean param is set to true, it flips the image vertical instead.

      * rotate

      rotate($degree, $backgroundColor=127)
      param: $degree - (integer) valid is -360 0 360 param: $backgroundColor - (integer) valid is 0 - 255, default is 127 return: pim - (class handle) This rotates the image. Positive values for degree rotates clockwise, negative values counter clockwise. If you use other values than 90, 180, 270, the additional space gets filled with the defined background color.
      -------------------------------------------------------------------

      * brightness

      brightness($level)
      param: $level - (integer) -255 0 255 return: pim - (class handle) You can adjust brightness by defining a value between -255 and +255. Zero lets it unchanged, negative values results in darker images and positive values in lighter images.
      -------------------------------------------------------------------

      * contrast

      contrast($level)
      param: $level - (integer) -255 0 255 return: pim - (class handle) You can adjust contrast by defining a value between -255 and +255. Zero lets it unchanged, negative values results in lesser contrast and positive values in higher contrast.
      -------------------------------------------------------------------

      * grayscale

      grayscale()
      return: pim - (class handle) Turns an image into grayscale. Remove all colors.
      -------------------------------------------------------------------

      * sepia

      sepia()
      return: pim - (class handle) Turns the memory image into a colorized grayscale image with a predefined rgb-color that is known as "sepia".
      -------------------------------------------------------------------

      * colorize

      colorize($anyColor)
      param: $anyColor - (array) like css rgb or css rgba - but with values for rgb -255 - +255,  - value for alpha is float 0 - 1, 0 = transparent  1 = opaque return: pim - (class handle) Here you can adjust each of the RGB colors and optionally the alpha channel. Zero lets the channel unchanged whereas negative values results in lesser / darker parts of that channel and higher values in stronger saturisation of that channel.
      -------------------------------------------------------------------

      * negate

      negate()
      return: pim - (class handle) Turns an image into a "negative".
      -------------------------------------------------------------------

      * pixelate

      pixelate($blockSize=3)
      param: $blockSize - (integer) 1 - ??, default is 3 return: pim - (class handle) This apply the well known PixelLook to the memory image. It is stronger with higher values for blockSize.
      -------------------------------------------------------------------

      * emboss

      emboss()
      return: pim - (class handle) This apply the emboss effect to the memory image.
      -------------------------------------------------------------------

      * edgedetect

      edgedetect()
      return: pim - (class handle) This apply the edge-detect effect to the memory image.
      -------------------------------------------------------------------

      * getMemoryImage

      getMemoryImage()
      return: memoryimage - (GD-Resource) If you want apply something that isn't available with that class, you simply can check out the current memory image and apply your image - voodoo - stuff
      -------------------------------------------------------------------

      * setMemoryImage

      setMemoryImage($memoryImage)
      param: $memoryImage - (GD-Resource) return: pim - (class handle) If you are ready with your own image stuff, you can check in the memory image for further use with the class.
      -------------------------------------------------------------------

      * watermarkLogo

      watermarkLogo($pngAlphaImage, $position='center', $padding=2)
      param: $pngAlphaImage - mixed [systemfilepath or PageImageObject] to/from a PNG with transparency param: $position - (string) is one out of: N, E, S, W, C, NE, SE, SW, NW,
      - or: north, east, south, west, center, northeast, southeast, southwest, northwest
      default is 'center' param: $padding - (integer) 0 - 25, default is 5, padding to the borders in percent of the images length! return: pim - (class handle) You can pass a transparent image with its filename or as a PageImage to the method. If the watermark is bigger than the destination-image, it gets shrinked to fit into the targetimage. If it is a small watermark image you can define the position of it:
      NW - N - NE | | | W - C - E | | | SW - S - SE  
      The easiest and best way I have discovered to apply a big transparency watermark to an image is as follows:
      create a square transparent png image of e.g. 2000 x 2000 px, place your mark into the center with enough (percent) of space to the borders. You can see an example here! The $pngAlphaImage get centered and shrinked to fit into the memory image. No hassle with what width and / or height should I use?, how many space for the borders?, etc.
      -------------------------------------------------------------------

      * watermarkLogoTiled

      watermarkLogoTiled($pngAlphaImage)
      param: $pngAlphaImage - mixed [systemfilepath or PageImageObject] to/from a PNG with transparency return: pim - (class handle) Here you have to pass a tile png with transparency (e.g. something between 150-300 px?) to your bigger images. It got repeated all over the memory image starting at the top left corner.
      -------------------------------------------------------------------

      * watermarkText

      watermarkText($text, $size=10, $position='center', $padding=2, $opacity=50, $trueTypeFont=null)
      param: $text - (string) the text that you want to display on the image param: $size - (integer) 1 - 100, unit = points, good value seems to be around 10 to 15 param: $position - (string) is one out of: N, E, S, W, C, NE, SE, SW, NW,
      - or: north, east, south, west, center, northeast, southeast, southwest, northwest
      default is 'center' param: $padding - (integer) 0 - 25, default is 2, padding to the borders in percent of the images length! param: $opacity- (integer) 1 - 100, default is 50 param: $trueTypeFont - (string) systemfilepath to a TrueTypeFont, default is freesansbold.ttf (is GPL & comes with the module) return: pim - (class handle) Here you can display (dynamic) text with transparency over the memory image. You have to define your text, and optionally size, position, padding, opacity for it. And if you don't like the default font, freesansbold, you have to point to a TrueTypeFont-File of your choice.

      PageImage Manipulator - Example Output


    • By d'Hinnisdaël
      Format Datetime fields as Carbon instances.
      You can find the latest release and the complete readme on Github.
      Installation
      composer require daun/datetime-carbon-format Usage
      All Datetime fields will now be formatted as Carbon instances instead of strings. Some examples:
      // $page->date is a Datetime field // Output format: j/n/Y echo $page->date; // 20/10/2020 echo $page->date->add('7 days'); // 27/10/2020 echo $page->date->format('l, F j'); // Monday, October 20 echo $page->date->year; // 2020 echo $page->date->diffForHumans(); // 28 minutes ago Frontend only
      The ProcessWire admin seems to expect datetime fields to be strings. This module will only return Carbon instances on frontend page views.
      Date output format
      When casting a Carbon instance to a string (usually when outputting the field in a template), the field's date output format will be respected.

      TrelloWire
      This is a module that allows you to automatically create Trello cards for ProcessWire pages and update them when the pages are updated. This allows you to setup connected workflows. Card properties and change handling behaviour can be customized through the extensive module configuration. Every action the module performs is hookable, so you can modify when and how cards are created as much as you need to. The module also contains an API-component that makes it easy to make requests to the Trello API and build your own connected ProcessWire-Trello workflows.
      Warning: This module requires ProcessWire 3.0.167 which is above the current stable master release at the moment.
      Features
      All the things the module can do for you without any custom code: Create a new card on Trello whenever a page is added or published (you can select applicable templates). Configure the target board, target list, name and description for new cards. Add default labels and checklists to the card. Update the card whenever the page is updated (optional). When the status of the card changes (published / unpublished, hidden / unhidden, trashed / restored or deleted), move the card to a different list or archive or delete it (configurable). You can extend this through hooks in many ways: Modifiy when and how cards are created. Modify the card properties (Target board & list, title, description, et c.) before they are sent to Trello. Create your own workflows by utilizing an API helper class with many convenient utility methods to access the Trello API directly. Feedback & Future Plans
      Let me know what you think! In particular:
      If you find any bugs report them here or on Github, I'll try to fix them. This module was born out of a use-case for a client project where we manage new form submissions through Trello. I'm not sure how many use-cases there are for this module. If you do use it, tell me about it! The Trello API is pretty extensive, I'll try to add some more helper methods to the TrelloWireApi class (let me know if you need anything in particular). I'll think about how the module can support different workflows that include Twig – talk to me if you have a use-case! Next steps could be a dashboard to manage pages that are connected to a Trello card, or a new section in the settings tab to manage the Trello connection. But it depends on whether there is any interest in this 🙂 Links

      ProcessWire InputfieldRepeaterMatrixDuplicate
      Thanks to the great ProModule "RepeaterMatrix" I have the possibility to create complex repeater items. With it I have created a quite powerful page builder. Many different content modules, with many more possible design options. The RepeaterMatrix module supports the cloning of items, but only within the same page. Now I often have the case that very design-intensive pages and items are created. If you want to use a content module on a different page (e.g. in the same design), you have to rebuild each item manually every time.
      This module extends the commercial ProModule "RepeaterMatrix" by the function to duplicate repeater items from one page to another page. The condition is that the target field is the same matrix field from which the item is duplicated. This module is currently understood as proof of concept. There are a few limitations that need to be considered. The intention of the module is that this functionality is integrated into the core of RepeaterMatrix and does not require an extra module.
      Check out the screencast
      What the module can do
      Duplicate multible repeater items from one page to another No matter how complex the item is Full support for file and image fields Multilingual support Support of Min and Max settings Live synchronization of clipboard between multiple browser tabs. Copy an item and simply switch the browser tab to the target page and you will immediately see the past button Support of multiple RepeaterMatrix fields on one page Configurable which roles and fields are excluded Configurable dialogs for copy and paste Duplicated items are automatically pasted to the end of the target field and set to hidden status so that changes are not directly published Automatic clipboard update when other items are picked Automatically removes old clipboard data if it is not pasted within 6 hours Delete clipboard itself by clicking the selected item again Benefit: unbelievably fast workflow and content replication What the module can't do
      Before an item can be duplicated in its current version, the source page must be saved. This means that if you make changes to an item and copy this, the old saved state will be duplicated Dynamic loading is currently not possible. Means no AJAX. When pasting, the target page is saved completely No support for nested repeater items. Currently only first level items can be duplicated. Means a repeater field in a repeater field cannot be duplicated. Workaround: simply duplicate the parent item Dynamic reloading and adding of repeater items cannot be registered. Several interfaces and events from the core are missing. The initialization occurs only once after the page load event Attention, please note!
      Nested repeaters cannot be supported technically. Therefore a check is made to prevent this. However, a nested repeater can only be detected if the field name ends for example with "_repeater1234". For example, if your MatrixRepeater field is named like this: "content_repeater" or "content_repeater123", this field is identified as nested and the module does not load. In version 2.0.1 the identification has been changed so that a field ending with the name repeater is only detected as nested if at least a two-digit number sequence follows. But to avoid this problem completely, make sure that your repeater matrix field does NOT end with the name "repeater".
