FCKEditor: Remove & prevent <p> tags from wrapping your content.

For some reason, FCKEditor automatically wraps any content entered into the textbox with a <p> tag. This can cause for some problems in your layout when you’re actually displaying the content. Instead of trying to fix this in your layout with CSS, there is a quick and easy way to turn the auto-wrap off in FCKEditor: Change the FCKConfig.EnterMode setting from ‘p’ to ‘br’. There are a few ways to handle this:

  • Edit fckconfig.js:
    Change FCKConfig.EnterMode = 'p'; to FCKConfig.EnterMode = 'br';
  • Change the setting programatically when you instantiate the object, like so (in PHP):
    $oFCKeditor = new FCKeditor('description');
    $oFCKeditor->BasePath = '/fckeditor/';
    $oFCKeditor->Value = 'some text';
    $oFCKeditor->Config['EnterMode'] = 'br'; // turn off auto <p> tags wrapping content

I prefer the latter way because you can do it on a page by page basis, and there’s no messing with FCK’s core JavaScript files.

FCKeditor Error: this.DOMDocument has no properties

In my prior post I ran into a problem with FCKeditor on Apache having to do with serving JavaScript files as the proper MIME type. I ran into a similar problem with XML files when trying to load multiple instances of FCK textareas:
Error: this.DOMDocument has no properties
Source File: http://www.mysite.com/FCKeditor/editor/js/fckeditorcode_gecko.js
Line: 43

This is easily fixed in the same way, by telling Apache how to properly serve XML files. Put this in your httpd.conf or an .htaccess file:
AddType text/xml .xml

FCKeditor in Firefox – Illegal Character JavaScript error

For some reason, FCKeditor would not load in Firefox 2.0 even though it loaded in IE just fine. Turns out Apache was serving up the javascript files as the wrong FileType, so Firefox would choke on some jibberish characters:
Error: illegal character
Source File: http://www.myserver.com/FCKeditor/editor/js/fckeditorcode_gecko.js
Line: 1, Column: 1
Source Code: /*

The fix is easy enough, simply add an .htaccess file to your dir containing the following:
AddType application/x-javascript .js
Now FCKeditor should work fine in Firefox.
