CKEditor - PDF upload module (like image upload)

Recommended Posts

Hi!

I'm relatively new to the world of Processwire, but so far I'm really impressed by this CMS and its ease, power and speed.

I've been looking at the different field types and also existing CKEditor modules (pwimage and pwlink).

Here's what i want to achieve:

I would like to use or create a own module which allows my admin users to upload pdf files inline in a CKEditor field (page content) the same way images are handled. It should be possible to upload a pdf file and specify its name and from the file uploaded and name i want to show an icon or image inline in editor and the output for that upload should be customized based on the module. Lets make it simple and say that i upload datasheet-1.pdf and want it to be named "My product datasheet", i want the output to be:

<a href="{ link to uploaded pdf file }">My product datasheet</a>

 

Also the uploaded pdf files should be related to the page the user is editing.

 

Is this doable? 

 

Any guidance would be greatly appreciated! Thanks in advance.

PS. I'm a PHP programmer so i know it would require some custom code, but the real question is where do i start, what should it take and is it even possible to do?

2 approaches:

  1. Textformatter
    Use a textformatter like https://modules.processwire.com/modules/process-hanna-code/
    or create your own. Use this as a starting point: https://modules.processwire.com/modules/textformatter-page-images/
  2. CKEditor Plugin
    Use a Filefield to upload files.
    Enable pwlink module in your CKEditor which allows you to link PW pages and files too.
    Add a css class to show the icon

Hi @kixe

Thanks for your reply (and sorry for my late response)!

I'm trying something like "2. CKEditor Plugin", but not with existing pwlink since it needs further customization.

 

A couple of questions:

  1. I'm looking at /wire/modules/Inputfield/InputfieldCKEditor/plugins/pwlink/plugin.js but i can't figure out how to create my own modalUri (var modalUri = config.urls.admin + 'page/image/';). I want to create the following path "https://www.domain.tld/processwire/page/pdf/?id=10&modal=1&modal=1" so that i can implement my own modal. Where do i find this?
  2. Do i need to create a module in order to get the above link and be able to create a modal with custom input fields?

I'm going to copy pwlink and modify to my needs but I'm stuck with the question:

Where can i create the routing for my modal (iframe url that loads the form created in ProcessPageEditLink.module, in my case ProcessPageEditPDF.module)?

PWlink uses:

https://www.domain.tld/processwire/page/link/?id=10&modal=1&modal=1

I want to use:

https://www.domain.tld/processwire/page/pdf/?id=10&modal=1&modal=1

 

How can i achieve that?

I want to clarify the reason i'll modify pwlink instead of using it.

 

Our users/administrators need to be able to click on one button in editor, select the file and write a anchor text and from that input we'll then generate something like this: 

<span class="row"><a href="/path/to/selected/pdf" class="pdf-link">Anchor text written by user</a></span>

If I understand you right you want to provide a simple file select if a user click the link icon in the CKEditor. I would do this with a hook in ProcessPageEditLink. Place the code in your ready.php

wire()->addHookAfter('ProcessPageEditLink::execute', null, function ($e) {
    // exit if page OR template doesn't match (modify for your needs)
    $pageID = wire('input')->get('id');
    if ($pageID != 1234) return;
    $templateID = wire('pages')->get($pageID)->template->id;
    if ($templateID != 123) return;

    $form = $this->modules->get("InputfieldForm");
    $form->attr('id', 'ProcessPageEditLinkForm');

    $field = wire('modules')->get('InputfieldSelect');
    $field->label = $this->_("Select File");
    $field->attr('id+name', 'link_page_file');
    $field->icon = 'file-pdf-o';

    // TODO: create an options array (path => label) from files stored in a file field (multi values) via ProcessWire API
    // example
    $options = array('/path/to/file/example.pdf' => 'nicePDF');

    $field->addOption(''); // allow unselect
    $field->addOptions($options);
    $form->add($field);
    // we need something like this to get the nice JS generated preview
    $markup = '<span id="link_page_url_input"></span>';
    $form->set('appendMarkup', $markup);
    $e->return =  $form->render() . "<p class='detail ui-priority-secondary'><code id='link_markup'></code></p>";
});

      Happy new year, everybody 🥬
      I've been sitting on this Dashboard module I made for a client and finally came around to cleaning it up and releasing it to the wider public. This is how it looks.
      ProcessWire Dashboard

      If anyone is interested in trying this out, please go ahead! I'd love to get some feedback on it. If this proves useful and survives some real-world testing, I'll add this to the module directory.
      Download
      You can find the latest release on Github.
      Documentation
      Check out the documentation to get started. This is where you'll find information about included panel types and configuration options.
      Custom Panels
      My goal was to make it really simple to create custom panels. The easiest way to do that is to use the panel type template and have it render a file in your templates folder. This might be enough for 80% of all use cases. For anything more complex (FormBuilder submissions? Comments? Live chat?), you can add new panel types by creating modules that extend the DashboardPanel base class. Check out the documentation on custom panels or take a look at the HelloWorld panel to get started. I'm happy to merge any user-created modules into the main repo if they might be useful to more than a few people.
       Disclaimer
      This is a pre-release version. Please treat it as such — don't install it on production sites. Just making sure 🍇
      Roadmap
      These are the things I'm looking to implement myself at some point. The wishlist is a lot longer, but those are the 80/20 items that I probably won't regret spending time on.
      Improve documentation & add examples ⚙️ Panel types Google Analytics ⚙️ Add new page  🔥 Drafts 🔥 At a glance / Page counter 404s  Layout options Render multiple tabs per panel panel groups with heading and spacing between ✅ panel wrappers as grid item (e.g. stacked notices) ✅ Admin themes support AdminThemeReno and AdminThemeDefault ✅ Shortcuts panel add a table layout with icon, title & summary ✅ Chart panel add default styles for common chart types ✅ load chart data from JS file (currently passed as PHP array) Collection panel support image columns ✅ add buttons: view all & add new ✅

      Hi everyone!
      I'm trying out the Login/Register module for my site. Noted that the module assigns the newly registered user to login-register role. 
      Once you modify the login-register role's permissions, particularly adding page-edit, the new member role will be set to guest. 
      Thing is I'd like to grant my new users the power to create their own pages. Any advice? 
      Thanks.

      Hello
      Till now I hacked something with the twig template but it works no more with new PW versions so I look forward to create a module. I am working on a site in multiple languages : French, English, Italian, German, Spanish, Portuguese, Hebrew, Russian. The new posts are entered in any language with a field for language. Till now, I got twig files to get the translations with constants defined for each part of the pages.
      So I'd like to create a module to include theses files added according to the url /fr/en/...
      Have you some observations to do before I begin about the direction to take ?
      Thank you

      Mystique Module for ProcessWire CMS/CMF
      Github repo : https://github.com/trk/Mystique
      Mystique module allow you to create dynamic fields and store dynamic fields data on database by using a config file.
      Requirements
      ProcessWire 3.0 or newer PHP 7.0 or newer FieldtypeMystique InputfieldMystique Installation
      Install the module from the modules directory:
      Via Composer:
      composer require trk/mystique Via git clone:
      cd your-processwire-project-folder/ cd site/modules/ git clone https://github.com/trk/Mystique.git Module in live reaction with your Mystique config file
      This mean if you remove a field from your config file, field will be removed from edit screen. As you see on youtube video.
      Using Mystique with your module or use different configs path, autoload need to be true for modules
      Default configs path is site/templates/configs/, and your config file name need to start with Mystique. and need to end with .php extension.
      Adding custom path not supporting anymore !
      // Add your custom path inside your module class`init` function, didn't tested outside public function init() { $path = __DIR__ . DIRECTORY_SEPARATOR . 'configs' . DIRECTORY_SEPARATOR; Mystique::add($path); } Mystique module will search site/modules/**/configs/Mystique.*.php and site/templates/Mystique.*.php paths for Mystique config files.
      All config files need to return a PHP ARRAY like examples.
      Usage almost same with ProcessWire Inputfield Api, only difference is set and showIf usage like on example.
      <?php namespace ProcessWire; /** * Resource : testing-mystique */ return [ 'title' => __('Testing Mystique'), 'fields' => [ 'text_field' => [ 'label' => __('You can use short named types'), 'description' => __('In file showIf working like example'), 'notes' => __('Also you can use $input->set() method'), 'type' => 'text', 'showIf' => [ 'another_text' => "=''" ], 'set' => [ 'showCount' => InputfieldText::showCountChars, 'maxlength' => 255 ], 'attr' => [ 'attr-foo' => 'bar', 'attr-bar' => 'foo' ] ], 'another_text' => [ 'label' => __('Another text field (default type is text)') ] ] ]; Example:
      site/templates/configs/Mystique.seo-fields.php <?php namespace ProcessWire; /** * Resource : seo-fields */ return [ 'title' => __('Seo fields'), 'fields' => [ 'window_title' => [ 'label' => __('Window title'), 'type' => Mystique::TEXT, // or InputfieldText 'useLanguages' => true, 'attr' => [ 'placeholder' => __('Enter a window title') ] ], 'navigation_title' => [ 'label' => __('Navigation title'), 'type' => Mystique::TEXT, // or InputfieldText 'useLanguages' => true, 'showIf' => [ 'window_title' => "!=''" ], 'attr' => [ 'placeholder' => __('Enter a navigation title') ] ], 'description' => [ 'label' => __('Description for search engines'), 'type' => Mystique::TEXTAREA, 'useLanguages' => true ], 'page_tpye' => [ 'label' => __('Type'), 'type' => Mystique::SELECT, 'options' => [ 'basic' => __('Basic page'), 'gallery' => __('Gallery'), 'blog' => __('Blog') ] ], 'show_on_nav' => [ 'label' => __('Display this page on navigation'), 'type' => Mystique::CHECKBOX ] ] ]; Searching data on Mystique field is limited. Because, Mystique saving data to database in json format. When you make search for Mystique field, operator not important. Operator will be changed with %= operator.
      Search example
      $navigationPages = pages()->find('my_mystique_field.show_on_nav=1'); $navigationPages = pages()->find('my_mystique_field.page_tpye=gallery');
