CKEditor for ProcessWire

CKEditor is a web text editor like TinyMCE. This module can be used anywhere TinyMCE can be used in ProcessWire.

CKEditor has a nice inline mode that is desirable in the page editor when you may have lots of rich text inputs. The reason for this is that the page editor loads a lot faster. Some people also prefer CKEditor for other reasons.

This module is tested and confirmed compatible with both repeaters and multi-language support.

1. Go to Setup > Fields and locate a textarea field that you want to use CKEditor (or create a new textarea field).

2. When editing the settings for a textarea field, click the Details tab. Change the Inputfield Type to CKEditor and save.

3. While still editing the field settings, click to the Input tab for CKEditor-specific settings you may optionally configure.

Inline Mode vs. Regular Mode

When configuring your CKEditor fields, you may notice the option of either Regular Mode or Inline Mode.

When you should use inline mode

The Inline Mode is new to CKEditor 4.x and is preferable if you need to have several instances of CKEditor on the same page at once. Inline mode editors are not initialized until hovered, making the initial page load time faster (at least versus several Regular Mode editors). Another benefit of inline mode is that the editor interface and buttons are not visible until the field is focused, which some may prefer visually. Another aspect of inline mode worth noting is that the editor area is always as tall as the content it contains... this may be good or bad, depending on your preferences. We recommend using inline mode in these instances:

• Multi-language textarea fields
• Textarea fields in repeaters
• Any instance where you have multiple (3+) CKEditor textarea fields in the same page editor.

When you should use regular mode

If you only have one or two instances of CKEditor on a page, you may prefer to use Regular Mode because it has been around longer and tends to be more reliable. Regular Mode runs in a separate frame, making it more isolated and thus less prone to any other CSS or Javascript interference. Regular mode editors are also more obviously rich text editors, as their interface and buttons are always visible. We recommend using Regular Mode in these instances:

• Page editors with only 1-2 CKEditor textarea fields (like body and sidebar).
• When you do not want CKEditor to consume too much vertical real estate on the editor page.
• When you want the greatest amount of compatibility with other CKEditor plugins.

Advanced Tips

This section contains contextual instructions that are linked to from within the module. These cover specific needs during field configuration and you do not need to read this section in order to use CKEditor.

Custom Editor JS Styles Set

This is an option that appears in your CKEditor field settings when editing a textarea field in the ProcessWire field editor. Use this option if you want to have a Styles dropdown that contains your own custom styles that users can choose from your editor.

Instructions

1. Edit your CKEditor field in Setup > Fields, and click to the Input tab.

2. In the CKEditor Toolbar field, enter Styles somewhere. Here is an example of what my first toolbar line looks like:
   Format, Styles, Bold, Italic, -, RemoveFormat

3. Open the Custom Editor JS Styles Set field, and type or paste in: mystyles:/site/modules/InputfieldCKEditor/mystyles.js

   • ProcessWire's default profile comes with a ready-to-go mystyles.js in the exact location mentioned above. Feel free to use this.

   • The term mystyles is just something we made up, and you may use whatever keyword you like, but note you will have to use that same keyword in the file itself. In our example below, you will see where we used the term mystyles again. If you want to keep things simple, then just stick with using mystyles.

   • If you don't have a mystyles.js file in /site/modules/InputfieldCKEditor/, then you can copy the one in /wire/modules/Inputfield/InputfieldCKEditor/ to /site/modules/InputfieldCKEditor/mystyles.js.

4. Edit and modify the mystyles.js file to suit your particular needs. Save and you are done.

When editing a page that uses your CKEditor field, you should now see a Styles dropdown with the styles you specified in your mystyles.js file. Note that you may not initially see all styles in the dropdown, as they may be contextual. For instance, you will not see the styles related to images in the example above unless you are focused on an img element in your editor.

You may wish to combine your settings here with a custom editor CSS file covered in the section below.

Custom Editor CSS File

This option enables you to modify the way that text and other elements appear in your editor. This covers how they look in the administrative environment only, and has nothing to do with the front-end of your site. Typically you would use this option if you wanted to modify the default look-and-feel in the editor to something that is more stylistically similar to the front-end of your site.

Example editor CSS files can be found here:

• Regular Mode: /site/modules/InputfieldCKEditor/contents.css
• Inline Mode: /site/modules/InputfieldCKEditor/contents-inline.css

You can use this files directory, or you can copy them somewhere else. However, since they are located in your /site/ directory, they won't get overwritten during upgrades. For the same reason, it's also possible that you don't have those files in the location mentioned above. If that's the case, you can copy the versions in /wire/modules/Inputfield/InputfieldCKEditor/ instead, and I recommend putting them in /site/modules/InputfieldCKEditor/.

There is also a Sass (SCSS) file called contents-inline.scss which you may prefer to use as your starting point if using Sass. Just remember to compile it to a contents-inline.css file when done. The Sass file is located here: /wire/modules/Inputfield/InputfieldCKEditor/contents-inline.scss

As you can see above, you will be using a different CSS file depending on whether you need to modify the styles in a regular editor, or an inline-mode editor.

1. Modify the file(s) mentioned above and style the elements as you wish, or you may return to this step later. If using more than one CKEditor inline editor in your page, please see the important note below these instructions.

2. Edit your textarea field that uses CKEditor in Setup > Fields > your_field. Go to the Input tab and see the Custom Editor CSS File option. Type or paste in the location of the file you copied in step 1 (relative to web root). Example: /site/modules/InputfieldCKEditor/contents.css. Save.

3. Your editor should now be using your new contents.css or contents-inline.css file rather than the defaults. Note that sometimes it can be difficult to see the results of your new file immediately, especially in regular mode, due to browser caching. If you run into trouble, quit your browser and re-open (or use Incognito mode).

Important Note About Inline Mode (contents-inline.css)

If using more than one CKEditor inline mode editor on your page, and not using the same contents-inline.css file on all of them, then you will end up having them compete with each other or fall back to the default contents-inline.css. In order to avoid this, you would need to make your CSS selectors more specific to the field they apply to.

Lets say that you had a field named body. You could target it specifically in your contents-inline.css (or whatever you named the file), by replacing this CSS selector...

.InputfieldForm .InputfieldCKEditorInline 

...with this CSS selector:

.InputfieldForm .Inputfield_body .InputfieldCKEditorInline 

Note the .Inputfield_body part, as body is the name of the field in ProcessWire.

If you will use the same contents-inline.css file for all of your inline fields, then just make sure it is specified with the settings for each of your CKEditor inline textarea fields, otherwise you may end up reverting back to the default contents-inline.css.
