An inputfield module that brings EasyMDE Markdown editor to ProcessWire.

EasyMDE is a fork of SimpleMDE, for which there is an existing PW module. Inputfield EasyMDE has a few advantages though:

  • EasyMDE seems to be more actively developed than SimpleMDE, which hasn't seen any updates for several years.
  • You can define options for Inputfield EasyMDE.
  • Inputfield EasyMDE can be used in Repeater fields and in custom fields for File/Image fields.

 

Inputfield EasyMDE

EasyMDE (Easy Markdown Editor) as an inputfield for ProcessWire.

EasyMDE is a Markdown editor with some nice features, allowing users who may be less experienced with Markdown to use familiar toolbar buttons and shortcuts. More information is at the EasyMDE website.

easy-mde

Installation

Install the Inputfield EasyMDE module.

Usage

Create a new textarea field, and in the "Inputfield Type" dropdown choose "EasyMDE". Save the field and if you like you can then configure the EasyMDE options for the field as described below.

To convert Markdown to HTML you can install the core TextformatterMarkdownExtra module and apply the textformatter to the field. Alternatively you can use $sanitizer->entitiesMarkdown() on the field value, e.g.

echo $sanitizer->entitiesMarkdown($page->your_field_name, ['fullMarkdown' => true]);

Configuration

On the "Input" tab of the field settings you can define EasyMDE options for the field in JSON format. Refer to the EasyMDE documentation for the available options. Keys in the JSON must be surrounded with double quotes.

Example:

"toolbar": ["bold", "italic", "heading", "|", "side-by-side"],  
"sideBySideFullscreen": false

This is great! Finally it is easily possible to ditch CKEditor. Thank you so much Robin!

You might want to add that using the Markdown/Parsedown Extra textformatter is needed as well. It might be obvious to some, but first time I tried without it 😛

Thx Robin for another great module! 🙂 

I'm always stripping down the interface of CKEditor as much as possible using your great hooks. I wonder where and why you'd be using this field? I think markdown is still too complicated for clients.

I'm not using any of those nowadays. Maybe that's why I can't think of where to use this field at the moment. But I'd be happy to hear where you are using it and what you dislike with ckeditor (or why you built the module in the first place). The only thing that I really don't like is copy/paste issues with custom formatting that can get annoying. But there's also a solution for this here.

@Robin S I cannot figure out how to style the preview. Have you already done that? Looks like the option named "previewClass" should be used somehow but I do not get what exactly this means: "previewClass: A string or array of strings that will be applied to the preview screen when activated. Defaults to "editor-preview".

Also, the example provided does not help much either:

previewClass: "my-custom-styling",
previewClass: ["my-custom-styling", "more-custom-styling"],

my-custom-styling it says, but where is it defined and how?

This module is just the inputfield and doesn't get involved with what the user might want to do with the field contents. But I take your point that some users might not know how to convert Markdown to HTML, so thanks for raising it. Using the textformatter you suggested is one way to get HTML from Markdown, or alternatively you could use $sanitizer->entitiesMarkdown() on the field value. I've added a paragraph to the readme.

For me personally, the current application is for getting HTML out of custom fields for File/Image fields because CKEditor isn't supported there. Although I emailed Ryan today with some suggested fixes for getting CKEditor working there so hopefully that might change soon.

More broadly I think some people just prefer working with Markdown rather than a full-blown WYSIWYG, so this is an inputfield for them. 🙂

I don't think EasyMDE has options for loading custom CSS - the previewClass option is just if you want to specify a different class name than the default on the preview wrapper element. If you want to target the preview element with custom CSS in Page Edit you could write style rules like this:

.InputfieldEasyMDE .editor-preview h1 { color:red; }

And load your custom CSS file with AdminOnSteroids or with a hook like this:

$wire->addHookBefore('ProcessPageEdit::execute', function(HookEvent $event) {
	$config = $event->wire()->config;
	$config->styles->add($config->urls->templates . 'custom-styles.css');
});

Thanks for the explanation, now it all makes sense to me 🙂

      Hey folks,
      for a module (a pagebuilder based on PageTable) I need to save some settings as JSON. The values are saved for each page table item (a pw page). It's working well, but I am looking for ways to improve the structure I have. As I'm not that experienced with JSON, maybe someone more experienced can take a look and tell me if my approach is good practice. 

      My goal is to make all the items accessible by page id, without looping over them (using objects instead of arrays):
      // access from template with pw page var $jsonObject->items->{$page}->cssClass; Her is an example of my JSON structure:
      { "items": { "3252": { "id": "3252", "cssClass": "pgrid-main", "breakpoints": { "base": { "css": { "grid-column-end": "auto", "grid-row-end": "auto", "grid-column-start": "auto", "grid-row-start": "auto", "align-self": "auto", "z-index": "auto", "padding-left": "60px", "padding-right": "60px", "padding-top": "60px", "padding-bottom": "60px", "background-color": "rgb(255, 255, 255)", "color": "rgb(0, 0, 0)" }, "size": "@media (min-width: 576px)", "name": "base" } } }, "3686": { "id": "3686", "cssClass": "test_global", "breakpoints": { "base": { "css": { "grid-column-end": "-1", "grid-row-end": "span 1", "grid-column-start": "1", "grid-row-start": "auto", "align-self": "auto", "z-index": "auto", "padding-left": "0px", "padding-right": "0px", "padding-top": "0px", "padding-bottom": "0px", "background-color": "rgba(0, 0, 0, 0)", "color": "rgb(0, 0, 0)" }, "size": "@media (min-width: 576px)", "name": "base" } } }, "3687": { "id": "3687", "cssClass": "block_editor-3687", "breakpoints": { "base": { "css": { "grid-column-end": "span 2", "grid-row-end": "span 1", "grid-column-start": "auto", "grid-row-start": "auto", "align-self": "auto", "z-index": "auto", "padding-left": "0px", "padding-right": "0px", "padding-top": "0px", "padding-bottom": "0px", "background-color": "rgba(0, 0, 0, 0)", "color": "rgb(0, 0, 0)" }, "size": "@media (min-width: 576px)", "name": "base" } } }, "3696": { "id": "3696", "cssClass": "block_editor-3696", "breakpoints": { "base": { "css": { "grid-column-end": "span 2", "grid-row-end": "span 1", "grid-column-start": "auto", "grid-row-start": "auto", "align-self": "auto", "z-index": "auto", "padding-left": "0px", "padding-right": "0px", "padding-top": "0px", "padding-bottom": "0px", "background-color": "rgba(0, 0, 0, 0)", "color": "rgb(0, 0, 0)" }, "size": "@media (min-width: 576px)", "name": "base" } } } }, "breakpointActive": "base", "breakpointActiveSize": "@media (min-width: 576px)" }

      Fieldtype Page Table Grid
      This is a sneak preview of a side project I've been working on for quite some time now. A lot of work and thought has gone into this, so I will most likely release this as a commercial module at some point in the near future. 

      As a designer (and developer) I get the appeal of a WYSIWYG editor. After playing around with some WYSIWYG page builder tools, I always felt something was wrong about them. So I decided to build my own PW version based on PageTable.

      Here is a small demo (using AdminThemeCanvas, but its working with other admin themes as well) :
      There is also a complete website that I built for a friend of mine using this module and some custom blocks.
      Concept
      This fieldtype shares a lot of features with PageTableExtended: it's also an extension of PageTable and renders the block templates in the backend and frontend (native PW templates and fields). You can also add your own css via module settings.
      The difference is, this fieldtype also gives you the ability to rearrange and resize elements in a visual way as well as enable inline editing for text, ckeditor and file fields. Similar (and promising) attempts have been made, but I wanted something based on native CSS grid instead of a CSS framework...so I built my own version. Most CSS frameworks are based on flexbox, which is great for layouting elements horizontally. With CSS grid, you can place elements horizontally and vertically, allowing for layouts that were not previously possible with CSS. Similar to webflow, this fieldtype uses javascript (in the backend) to let you manipulate CSS grid in a visual way to design fully responsive websites (or parts of them). It should still be possible to include a CSS framework if you like (just add the classes to your block markup and include the CSS via module settings).
      The CSS grid layout manipulations are saved in a single field as a JSON array and used to generate a dynamic stylesheet that you simply include in your main template (no inline styles). The styles are saved within the breakpoint you select and cascade down to smaller breakpoints. That means you can specify just the basic breakpoint and adjust other breakpoints if needed. The exception is the mobile breakpoint which will display everything in one column as a default (you can change the layout here too).
      The fieldtype also comes with an optional style panel to manipulate some additional CSS properties directly on the page. You can customize the panel or disable it completely from the module settings (and just use a CSS file that you include via module settings). The style panel is based on inputfields (nothing is saved to the database). This means that you just have to install the module and all fields are available to all blocks automatically (this can be customized). It also has the benefit that your installation is not flooded with fields; this module only installs one field.
      Don't want to give your customer all that power? Design features can be disabled for certain roles. The grid editor role can just edit the content and use the inline editing feature to edit content quickly. You can then also grant access individually to the style panel, resize or drag functionality.
      Features
      Blocks are just pages Blocks are defined by native PW templates and fields Manipulate CSS grid in a visual way to design fully responsive websites (or parts of them) Design features can be disabled for certain roles Inline editing of text, ckeditor and file fields The layout is 100% CSS grid (very small css file size) Simply drag and resize to manipulate grid items directly inside the backend Manipulate grid columns and rows directly on the page (use any number of columns you want) All style manipulations are saved as JSON and used to generate a dynamic stylesheet that you just include in your main template (no inline styles) Nested groups/grids (child pages of nested blocks are created under group parent) Global blocks work with page reference field (changes on one page, changes all blocks on all pages) Manual and auto placement of grid items Define custom icons for your blocks via native template settings (template -> advanced -> icon) Option to load lazysizes in the backend to enable lazy loading of assets with class lazyload Works with all default and ui-kit based admin themes If you have any questions or feedback, let me know.

      I built this module because I needed a versatile solution to replace tags and simple if-blocks in some E-Mails and PDF documents.
      If you only need to replace static tags (no if-conditions), then you can use default PW api and need no module:
      $str = "My favourite color is {color}."; $texttools = $sanitizer->getTextTools(); echo $texttools->populatePlaceholders($str, ['color' => 'red']); // output: My favourite color is red. Usage:
      See the two example Files in the folder /replacements

       
      Methods:
      replacementsTable()
      Renders an overview of all available replacements (see the example in the Module's config file:
       
      Create new Replacements:
      Simply copy the sample file and adopt to your needs.

      DEPRECATED
      I'm using this module in several projects, but it will likely not see any updates in the future. I'm not happy with it and I'm looking for ways to develop better solutions. RockTabulator was my first try, but I'm also not 100% happy with that. The tabulator library is great, but my module implementation is not. I hope to get a good solution soon, but it will be a lot of work...
      ---
      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.

      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 (please contact me via PM).
       
      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:

      Hi there. I wrote a custom module for one of my projects. In fact I maybe want to use my module in other projects too. In order to be variable and customizable  I need to implement some custom hooks into my module. So I can afterwards hook into the my functions in order to modify them to match the needs of the new project.
      I tried simply defining functions with the '__' prefix. But that did not work. I'm imagining something like the following:
      <?php class MyClass { public function ___someFunction() { // Do something } } // ready.php $this->addHookBefore('MyClass::someFunction', function($event) { // some customization }); Is there a way to accomplish that?
