RockGrid - powerful, performant and beautiful data listing tool

Recommended Posts

Some of you might have followed the development of this module here: https://processwire.com/talk/topic/15524-previewdiscussion-rockdatatables/ . It is the successor of "RockDataTables" and requires RockFinder to get the data for the grid easily and efficiently. It uses the open source part of agGrid for grid rendering.

 

WHY?

ProcessWire is awesome for creating all kinds of custom backend applications, but where it is not so awesome in my opinion is when it comes to listing this data. Of course we have the built in page lister and we have ListerPro, but none of that solutions is capable of properly displaying large amounts of data, for example lists of revenues, aggregations, quick and easy sorts by the user, instant filter and those kind of features. RockGrid to the rescue 😉 

 

Features/Highlights:

  • 100k+ rows
  • Instant (client side) filter, search, sort (different sort based on data type, eg "lower/greater than" for numbers, "contains" for strings)
  • extendable via plugins (available plugins at the moment: fullscreen, csv export, reload, batch-processing of data, column sum/statistics, row selection)
  • all the agGrid features (cell renderers, cell styling, pagination, column grouping etc)
  • vanilla javascript, backend and frontend support (though not all plugins are working on the frontend yet and I don't plan to support it as long as I don't need it myself)

 

Limitations:

While there is an option to retrieve data via AJAX the actual processing of the grid (displaying, filtering, sorting) is done on the client side, meaning that you can get into troubles when handling really large datasets of several thousands of rows. agGrid should be one of the most performant grid options in the world (see the official example page with a 100k row example) and does a lot to prevent problems (such as virtual row rendering), but you should always have this limitation in mind as this is a major difference to the available lister options that do not have this limitation.

Currently it only supports AdminThemeUikit and I don't plan to support any other admin theme.

Contribute:

You can contribute to the development of this and other modules or just say thank you by

 

Support: Please note that this module might not be as easy and plug&play as many other modules. It needs a good understanding of agGrid (and JavaScript in general) and it likely needs some looks into the code to get all the options. Please understand that I can not provide free support for every request here in the forum. I try to answer all questions that might also help others or that might improve the module but for individual requests I offer paid support for 60€ per hour (excl vat).

 

Use Cases / Examples:

Colored grid cells, Icons, Links etc. The Grid also has a "batcher" feature built in that helps communicating with the server via AJAX and managing resource intensive tasks in batches:

Filters, PW panel links and instant reload on panel close:

You can combine the grid with a chart library like I did with the (outdated) RockDataTables module:

Thank you Bernhard for finally releasing this module. I can not wait to play with it and share improvements, if I have any.

I really can think of many use cases where this grid would be mandatory because it offers so much possibilities.

I installed the module and RockFinder, but when calling "Rock Finder Tester" the SQL query works, but no grid is displayed.

There is a JavaScript error in the console which looks like this:

(index):205 Uncaught ReferenceError: RockGrid is not defined
    at initGrid_ProcessRockFinderResult ((index):205)
    at (index):216

The problem was, that I did not rename the downloaded folder from Gitlab from "RockGrid-master" to "RockGrid". After doing this, it works

Installing the zip (either from URL or Upload), rather than manually unzipping takes care of this stuff for you 🙂

Why I'm always the one who still have the error.😂 I did install via upload of zip and I have /modules/RockGrid.

However, I still have errors:

image.thumb.png.1a690cdab44cc61ff9422825ef509b5a.png

1)The path is wrong for js, it should be : localhost/24h/site/assets/RockGrid/fields/test_grid.js

2)error mentioned earlier

 

Also, not related, but playing with the Tester, I wrote some wrong code which gave me a red error page. The problem is that I didn't know how to reset. (finally I reinstalled since of error above).

Thanks!

Hi mel,

thanks for testing and reporting those issues 🙂 

can you please provide a reproducable step-by-step guide what you did so I can look into that?

Thanks, I'm aware of that and it's definitely not nice to have this. I thought I've already fixed that 🙂 If it happens again please just delete the /site/assets/RockFinder/tester.txt file than it will create a new one. Or just edit it in your IDE and fix the problem.

Hope that helps?

Hi

Sorry for the delay, was too sunny to stay inside... 😉

So to recap. I tried on 2 installations (one with my current site and one empty, ie no module). Both are local, running php 7.0. I'm using firefox.

  1. Install rockfinder via module repository
  2. install rockgrid by url (https://gitlab.com/baumrock/RockGrid/-/archive/master/RockGrid-master.zip)
  3. create a "projects" rock-grid field and add it to home template
  4. Go to home template; see an empty white field with this error:
     ReferenceError: RockGrid is not defined[En savoir plus] edit:118:7
    initGrid_projects http://localhost/wire/processwire/page/edit/:118:7
    <anonyme> http://localhost/wire/processwire/page/edit/:129:7
     
  5. Add to /site/assets/RockGrid/fields/projects.js and project.php (copied from usage instructions. Now see this error
    Échec du chargement pour l’élément <script> dont la source est « http://localhost/site/assets/RockGrid/fields/projects.js ». edit:61 

    as mentioned earlier it's not the good address, it missing the domain, in this case : http://localhost/wire/site/assets/RockGrid/fields/projects.

Hope it helps.

PS No error during module installation. Debug info display under the field seems ok (default mysql query):

Same result, juste a name change.

    var gridSettings_rockgriddemo = {
      grid: 'rockgriddemo',
      dataColumns: ["id","title","created"],
      data: "ajax",
      js: {"settings":{"initPageSize":10,"pageSizes":[10,25,50,100],"height":300}},
    };

    var initGrid_rockgriddemo = function() {
      RockGrid.init(gridSettings_rockgriddemo);    //////ERROR IS HERE
      RockGrid.getGrid('rockgriddemo').str = RockGridStr_rockgriddemo    }

    // load the grid automatically or manually?
    if(typeof onLoad_rockgriddemo == 'function') {
      // load grid manually
      // sometimes this is needed when we have to wait for other grids to be loaded
      onLoad_rockgriddemo(gridSettings_rockgriddemo, RockGridStr_rockgriddemo);
    }
    else {
      // load this grid when dom is loaded
      initGrid_rockgriddemo();  ///////ERROR IS HERE
    }
    </script>

 

If I don't put the .js file I have no extra error. If I add it to /site/assets/Rockgrid/fields/

I get error (404) :

Quote

Échec du chargement pour l’élément <script> dont la source est « http://localhost/site/assets/RockGrid/fields/rockgriddemo.js ».

I try add to frontend, but same result, a white space, with same errors than below.

For the tester, don't exactly what means "work" since I never used. But there nothing in "result", but the "resulting sql" is updated accordingly of changes done in "code to execute". 

I certainly do something wrong or don't have something activated correctly. Will give up for now, since I have other things to do. I will continue to follow the thread in case a solution eventually come out. Thanks for you time.

Hi @bernhard I tried to test and reproduce why this isn't working.

When you install RockGrid and RockFinder from URL from Gitlab, then the RockGrid is downloaded and installed into a folder named "FieldtypeRockGrid". But RockFinder tries to look for files in a folder named "RockGrid".

So Rockfinder tester isn't working and shows the error that I described and @mel47 also described. That's the first problem.
You can solve it, if you download the zip file from gitlab, unzip it in your site/modules folder and remove the "-master" from the folder name, so the name of the folder is "RockGrid".

The second problem is, that if your processwire installation is not in the root of the virtual host of Apache (for example in a subdirectory), then the URLs for loading RockGrid's assets isn't correct because it tries to load the files from the root and does not take the subdirectory into account.

In one example installation I have two separate PW installations under the same virtual host but in different subdirectories (mydomain.localhost/pw1, mydomain.localhost/pw2). That might be the exact same problem that @mel47 has. If you open RockTester then it is trying to load http://mydomain.localhost/site/modules/RockGrid/plugins/cellHoverInfo.css instead of http://mydomain.localhost/pw1/site/modules/RockGrid/plugins/cellHoverInfo.css

Thanks for your help @jmartsch !

I renamed all references to FieldtypeRockGrid, so it should work now without renaming the folder. Thanks for that hint! Maybe someone wants to create a PR for the problem of installations inside a subfolder - I don't have any need for that and therefore will not implement it. At least not soon.

I created a screencast of a demo installation via PW Kickstart, the Kickstartfile is here: https://gitlab.com/snippets/1732038 ; Of course you can also install everything manually.

Thanks, looks pretty amazing even for my very small testing. I generally learning by reading other's code examples. Since there mostly anything, I have a quick question.

I could display really easily page and repeater independently. But is it possible to display the title of page found inside a repeater ? For now I only have id. I tried many ways, but without success, but I'm not sure if I'm trying to do something impossible or not.

Thanks!

I think I found a little glitch in the module. I've installed the module within a subdir based pw instance. Then the module won't find the nessecary js and css files. The field shows on the page edit page only a blank value and not that it find's no data.

I fixed it - for me - with the following change at line 64 in file site/modules/FieldtypeRockGrid/FieldtypeRockGrid.module.php:

Quote

// make sure the path is relative to the rootfolder
//$asset = str_replace($this->config->paths->root, '/', $asset);
$asset = str_replace($this->config->paths->root,$this->config->urls->root, $asset);

After that it seems to work for me.

Many thanx for the great module!!!

I am creating an updated web interface for an international proverb database (without pay). RockGrid should go a long way in providing a navigation system for it, so thank you very much for it! However, I can only make it work in the backend.

For the frontend, is it really enough to have $page->rockgrid; in the home.php (using blank profile)? No markup is needed in templates? I mean, it does load all the RockGrid assets in the frontend, but the grid element does not manifest. I did try a variation, where I had a div with id RockGridItem_rockgrid or the wrapper, but it did not help.

Here is my setup:

Field name is rockgrid.

home.php:


include("./basic-page.php");
$page->rockgrid;

basic-page.php loads jquery-3.3.1.min.js

rockgrid.php:


<?php namespace ProcessWire;

// set data for this grid via rockfinder
$this->setData(new RockFinder('template=A-T', ['code', 'variation']));

rockgrid.js:


document.addEventListener('RockGridItemBeforeInit', function(e) {
  if(e.target.id != 'RockGridItem_rockgrid') return;
  var grid = RockGrid.getGrid(e.target.id);

  var col = grid.getColDef('code');
  col.headerName = grid.js.code;

  var col = grid.getColDef('variation');
  col.headerName = grid.js.variation;

});

document.addEventListener('RockGridItemAfterInit', function(e) {
  if(e.target.id != 'RockGridItem_transactions') return;
  var col;
  var colDef;
  var grid = RockGrid.getGrid(e.target.id);  
});

The only JS warning is Loading failed for the <script> with source “http://localhost:2015/site/modules/RockGrid/lib/currency.min.js”, which is irrelevant.

Edit: I also tried putting it in the basic-page template. I installed Tracy Debugger, but I don't know what I should be looking for.

Edit: silly stuff here, nothing to see.

I started fiddling with the InputfieldRockGrid.module.php file. There is something wrong with output buffering. After ob_start(); I put $status = ob_get_status(); var_dump($status); and I get nothing.

PHP setting output_buffering is 4096 in my dev env. What can I do?

Edit: in the same dev env, if I do a simple test file with only ob_start and dump, it works. So what gives in RockGrid's case? I mean, I can get the value of $data just before ob_start.

ob_start works fine in a PW template as well. The problem is only manifesting in the input field PHP.

Edit2: if I comment out ob_start(); and return ob_get_clean();, the page gets rendered twice, but at least in the second rendering the grid is included.

Hi @Beluga please can you provide detailed step-by-step instructions so that I can try to reproduce your issue. I don't really get what is wrong. Is it not working as expected?

Edit: Sorry, I missed your first post.

Please follow the quickstart tutorial here: https://gitlab.com/baumrock/FieldtypeRockGrid/wikis/quickstart

From there you can continue adding features and always check wether it is working on the frontend or not. Some plugins do not have front-end-support yet. Most of the times it should not be hard to make them work on the frontend too.

Please report back if the quickstart tutorial is working for you.

The qs tuto is what I used. Can you shed light on the ob_start() problem? Why is it not working in the context of RockGrid?

Ok, second try, minimal example with enumerated steps.

1. Create PW install with blank profile

2. Install RockFinder & RockGrid

3. Create rockgrid field named "rockgrid"

4. Add the rockgrid field to home template

5. Edit basic-page.php and add


<script src="https://code.jquery.com/jquery-3.3.1.min.js" integrity="sha256-FgpCb/KJQlLNfOu91ta32o/NMZxltwRo8QtmkMRdAu8=" crossorigin="anonymous"></script>

inside the head and


<div><?php $page->rockgrid; ?></div>

inside the body

6. Create the rockgrid.php:


<?php namespace ProcessWire;

// set data for this grid via rockfinder
$this->setData(new RockFinder('template=home', ['title']));

7. Create the rockgrid.js:


document.addEventListener('RockGridItemBeforeInit', function(e) {
  if(e.target.id != 'RockGridItem_rockgrid') return;
  var grid = RockGrid.getGrid(e.target.id);

  var col = grid.getColDef('title');
  col.headerName = grid.js.title;

});

document.addEventListener('RockGridItemAfterInit', function(e) {
  if(e.target.id != 'RockGridItem_transactions') return;
  var col;
  var colDef;
  var grid = RockGrid.getGrid(e.target.id);  
});

8. Navigate to the home page and see that the grid is not rendered. Viewing the source, see that the RockGrid assets are in place. This means the execution of getData function in InputfieldRockGrid has been successful and it trips up at line 110 with ob_start(); for some reason.

hey @Beluga

I tried your steps and cannot reproduce your error:

It works as expected. I used the default profile and the latest versions of rockgrid + rockfinder (used git clone with the master branches).

I tried it without output buffering and it works normally.

Where is this line 110 ob_start() exactly sitting? Do you use a prepend file? Is it in your basic_page.php template?

Is 

<div><?php $page->rockgrid; ?></div>

right after ob_start() ?

I tried it out now like this:

<div id="rockgriddemo">
  <?php
  $grid = $page->rockgriddemo;
  ob_start();
  echo $grid;
  ob_end_flush();
  ?>
</div>

And everything still works normally. But I haven't used output buffering in a long long time. Not even sure I am using it correctly...

        when working with PW version 2.6+, please use Pim2, not Pim!
        read more here  on how to change from the older to the newer version in existing sites
      ---------------------------------------------------------------------------------------------------------------------------------
      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.
       
      You may also visit the post with tips & examples for users and module developers.


      How to Install
      Download the module Place the module files in /site/modules/PageImageManipulator/ In your admin, click Modules > Check for new modules Click "install" for PageImageManipulator Done! There are no configuration settings needed, just install and use it. Download    (version 0.2.0)
      get it from the Modules Directory History of origins

      http://processwire.com/talk/topic/3278-core-imagemanipulation/


      ----------------------------------------------------------------------------------------------------------


      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!
      -------------------------------------------------------------------

      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.

      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()
      -------------------------------------------------------------------

      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".
      Changelog
