ProcessMention: "Forum Mentions" style page link autocomplete for CKEditor

Recommended Posts

Since I was stuck to my flat today I took up a wish and rolled a Process module / CKEditor plugin combo that adds @-autocomplete like the mentions here in the forum to CKEditor fields. It's configurable, but only in module settings for now, the positioning of the select list is quite off and there's still some visual work to be done, so it is in early alpha state.

Nonetheless, if you want to take a look, here it is:



After installation, you may want to look into the "Additional selector" entry in the module's settings. You will most likely want to limit results to certain templates there.


Edit: Updated to version 0.0.30 with fixed positioning of the dropdown.
Edit2: Settings are configurable in field context now. If pwmentions is enabled, the according settings are shown on the "Input" tab.

thank you for your effort. ;)

I tried your ProcessMention module, and it does not work (see below). However, ...

... I could suggest:

  • In the file > Installation, you can add the step "Copy ProcessMention.css and ProcessMention.module from the module folder to the site/modules/InputfieldCKEditor directory.

... I have to say:

  • Rather than querying the server every time via Ajax to get mentions, you could cache the mentions client-side (in a hidden HTML element, local storage or JS config) - credit
  • Of course, the output  (e.g. fix positioning of selection list in plugin.js) is important.

Regarding my issue with the ProcessMention module, when I type the e.g. @Sca text then the Ajax-HTTP request is fired but I get the following Network Headers:


Note: In the image, the gray-covered areas are the path to access the admin of my PW installation.

P.S.: I read the code and I would help someway, but I have to learn a little more about github and the languages. :rolleyes:

@LAPS: thanks for the feedback. I'm not sure how the redirect comes to be and need to ponder that and perhaps run some more tests. What PW version are you on? Do you have languages active?

The positioning issue has meanwhile been fixed.

This isn't necessary. The .module and .css file are fine in their own module directory underneath site/modules (and keeping two copies under site/modules is like to lead to trouble). It's just the plugin.js that needs to go into the InputfieldCKEditor/plugins/pwmentions path so both the editor and PW can pick it up.

I'm not sure client side caching is much of an issue, as every keystroke will change the result list and the unfiltered list might be far too long to download. I usually only do that with decent sized lists when I perform client-side filtering.

Update: settings can now be changed on per-field basis on the fields' "Input" tab. Latest version is on github.

@BitPoet The module doesn't remove the mention page on uninstall, it's not found because it's hidden.

If you create it in the getModuleInfo method it will be removed by PW on uninstall.

public static function getModuleInfo() {
	return array(
		"page" => [
			"name" => "mention",
			"title" => "Mention",
			"status" => "hidden"

I am using ProcessWire 3.0.62 and I do not have languages active.

I installed the latest version of ProcessMention, but I continue to get the '301 Moved Permanently' from http://localhost:8888/ADMIN-PATH/mention.

However, if I use, it seems to work a little more: I get a 200 OK response but the "list of mentions" is not populated because the response code is an entire HTML page (including css, js, etc.).

@LAPS: I just tested it with a stock 3.0.62 (basic profile) in different browsers and the module works there, so it's likely some leftover / failed cleanup from an older install. Can you uninstall the module in the backend and make sure that you don't have any pages named "mention" in the page tree under Admin? If yes, just delete it manually. Also, please check that you don't have an older module version lying around in the InputfieldCKEditor directory.

Then, best download the very latest version (0.0.70) from the github repo  and install that. Don't forget to copy plugins.js into the correct path, and best clear your browser cache. After installing the module, you should see a page titled "Mention Autocomplete" in the page tree under Admin.

Glad to hear :) Then all that's left is a webserver or hostname lookup configuration issue. Probably related to IPv6. Disabling IPv6 in the web server may be enough to fix this.

      I've created a small module which lets you define a timestamp after which a page should be accessible. In addition you can define a timestamp when the release should end and the page should not be accessable any more.
      PageAccessReleasetime can be installed like every other module in ProcessWire. Check the following guide for detailed information: How-To Install or Uninstall Modules
      After that, you will find checkboxes for activating the releasetime-fields at the settings-tab of each page. You don't need to add the fields to your templates manually.
      Check e.g. the checkbox "Activate Releasetime from?" and fill in a date in the future. The page will not be accessable for your users until the given date is reached.
      If you have $config->pagefileSecure = true, the module will protect files of unreleased pages as well.
      How it works
      This module hooks into Page::viewable to prevent users to access unreleased pages:
      public function hookPageViewable($event) { $page = $event->object; $viewable = $event->return; if($viewable){ // If the page would be viewable, additionally check Releasetime and User-Permission $viewable = $this->canUserSee($page); } $event->return = $viewable; } To prevent access to the files of unreleased pages, we hook into Page::isPublic and ProcessPageView::sendFile.
      public function hookPageIsPublic($e) { $page = $e->object; if($e->return && $this->isReleaseTimeSet($page)) { $e->return = false; } } The site/assets/files/ directory of pages, which isPublic() returns false, will get a '-' as prefix. This indicates ProcessWire (with activated $config->pagefileSecure) to check the file's permissions via PHP before delivering it to the client.
      The check wether a not-public file should be accessable happens in ProcessPageView::sendFile. We throw an 404 Exception if the current user must not see the file.
      public function hookProcessPageViewSendFile($e) { $page = $e->arguments[0]; if(!$this->canUserSee($page)) { throw new Wire404Exception('File not found'); } } Additionally we hook into ProcessPageEdit::buildForm to add the PageAccessReleasetime fields to each page and move them to the settings tab.
      In the current version, releasetime-protected pages will appear in wire('pages')->find() queries. If you want to display a list of pages, where pages could be releasetime-protected, you should double-check with $page->viewable() wether the page can be accessed. $page->viewable() returns false, if the page is not released yet.
      If you have an idea how unreleased pages can be filtered out of ProcessWire selector queries, feel free to write an issue, comment or make a pull request!

      Thanks to the great Pro module "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 this module on a different page (e.g. in the same design), you have to rebuild each item manually every time.
      With this proof of concept I have created a module which adds the feature to copy a repeater item to the clipboard so that you can paste this item to another page with the same repeater field. The module has been developed very rudimentarily so far. It is currently not possible to copy nested items. There is also no check of Min/Max. You can also only copy items that have the same field on different pages. And surely you can solve all this more elegantly with AJAX. But personally I lack the deeper understanding of the repeaters. Also missing on the Javascript side are event triggers for the repeaters, which would make it easier. Like e.g. RepeaterItemInitReady or similar.
      it would be great if @ryan would implement this functionality in the core of RepeaterMatrix. I think he has better ways to implement this. Or what do you think, Ryan?
      Everybody is welcome to work on this module and improve it, if it should not be integrated into the matrix core. Therefore I put it for testing and as download on GitHub:
      You can best see the functionality in the screencast:

      Please take a look at this:
      The upper nav bar, including dropdowns like "pages" and "portfolios", what do you call this whole thing? At first I guess it's called "dropdown nav bar", but seems not.
      AND of course, what's the simplest way/module to achieve this in PW?
      Thanks in advance.

      Hey, I'm new and I created a simple module for tagging pages because I didn't found a module for it (sadly this is not a core feature). This module is licensed under the GPL3 and cames with absolutly no warranty at all. You should test the module before using it in production environments. Currently it's an alpha release. if you like the module or have ideas for improvements feel free to post a comment. Currently this fieldtype is only compatible with the Inputfield I've created to because I haven't found  an Inputfield yet, that returns arrays from a single html input.

      I'm creating a module to integrate into ProcessWire. You actually don't even need a module. You could just use the "Other Websites" javascript provided by PushAlert for basic functionality, ie send a broadcast notification to all subscribers. This is essentially what all the other integrations, including WordPress, do. The WP integration installs a widget with a form enabling the admin to enter details such as title, message, etc from a blog post. It does not:
      collect any statistics within the CMS about the notification enable audience fine tuning to eg a particular subscriber or subscriber segment within WP. The admin needs to use the PA dashboard for that functionality PushAlert has a javascript and REST API. It's intended that this module will use both. 
      What my module does so far:
      associate a subscription with a user. FE user clicks a button on the website front end to subscribe and/or agrees to the browser popup to accept notifications from this site send broadcast push alerts from a page within admin It doesn't have a 'widget' but easy enough to create a fieldsetpage with the relevant fields and add that fs page to any appropriate templates, then with a hook, send the notification. Need to be careful that once published/sent, the notification is not automatically re-sent on subsequent page edits.
      Looking for help/collaboration on how best:
      to send a notification, eg from a blog post, then track the statistics. Dilemma is that the push notification must come from the admin page. Responses go to the sending page which, as it's an admin page, is restricted and will not accept the https response. This is where the other CMS integrations stop. The only json response from PushAlert is the status, eg 'success', and the notification id. There is no opportunity at this point to capture the sending page id. handle, 'once sent on page publish', do not automatically resend on future page edits Am thinking along the lines that FS Page will have a @kongondo runtime markup field to pull the stats from PushAlert. Every time an admin visits the page, the stats will update.
      Once an admin checks the 'Send notification on page publish' checkbox, a hook creates new front end page that records the 'sender page', sends the notification request to PA, which then uses that newly created frontend page, as the response endpoint. Another rook re-associates the front end page with the admin page (eg blog post), to update the stats.
      Potential use cases:
      Notify individual and/or users with a particular role of an event, eg "New work opportunity" for job seekers; new blog post published; entries now open, etc...
      Looking for help/ideas/collaboration on this module. Please let me know if you're interested and as I do, believe this would be a great addition to ProcessWire
