CKEditor for Drupal 6 Installation Process (Open Source Version)

important note
These instructions assume that you install the CKEditor for Drupal module in the sites/all/modules directory (recommended). If you want to use the sites/all/libraries/ directory, you will need to adjust the paths given in the instructions accordingly.

If you want to install the CKEditor module on your Drupal 6 site, follow the steps described below.

First of all, download the installation package (.zip or tar.gz archive) for Drupal 6 from the official CKEditor for Drupal module site at

Unpack the contents of the installation package into the drupal/sites/all/modules directory. When the files are unpacked, you should see the following file structure inside the drupal/sites/all/modules directory:

modules                <dir>
   ckeditor            <dir>
      ckeditor         <dir>
      images           <dir>
      includes         <dir>
      plugins          <dir>

Download standalone CKEditor from Unpack the contents of the ckeditor directory from the installation package to the sites/all/modules/ckeditor/ckeditor (or sites/all/libraries/ckeditor) directory.

important note
You can skip uploading the _samples and _source folders. See the Minimum Setup article for some more tips regarding the minimum required CKEditor setup.

Go to the Administration Panel of your Drupal 6 site and choose the Modules option from the Site Building section. Scroll down to the User interface section and select the checkbox next to the CKEditor module name.

Enabling the CKEditor module in the Drupal 6 Administration Panel

You will now need to grant permissions for using CKEditor to selected roles in the Administration panel > User management > Permissions section. Scroll to the ckeditor module section and select the checkbox next to the access ckeditor permission for the roles that you want to grant this permission to.

Granting permission to use CKEditor in the Drupal 6 Administration Panel

You can now enter the configuration of your CKEditor for Drupal module by visiting the Administration panel > Site configuration > CKEditor section. If you want to enable CKFinder, an advanced Ajax file browser, see the Installing CKFinder article.

You should now adjust CKEditor profiles in the Administration panel > Site configuration > CKEditor section. Profiles determine which options are available to users based on system-wide roles. In each profile you can choose which textareas will be replaced by CKEditor, select a default toolbar, and configure some more advanced settings. Please note that User 1 must be assigned a system role that corresponds to the privileges required. If no role is assigned to User 1, they will have the privileges of "authenticated user".

important note

Certain text formats (e.g. Filtered HTML) limit allowed HTML tags, so after saving the content you may notice that some tags created with CKEditor are removed. The list of allowed HTML tags can be configured in the Administration panel > Site configuration > Input formats.

Below is a short list of tags that can be created with CKEditor (form elements are not included in this list):

      <a> <p> <span> <div> <h1> <h2> <h3> <h4> <h5> <h6> <img> <map> <area> <hr>
      <br> <br /> <ul> <ol> <li> <dl> <dt> <dd> <table> <tbody> <th> <tr> <td> <em> <b> <u> <i> <strong>
      <del> <ins> <sub> <sup> <quote> <blockquote> <pre> <address> <code>
      <cite> <embed> <object> <param> <strike> <caption> <iframe>

Note: Be careful when granting users access to create tags like <iframe>.

In order to have better control over line breaks, you may disable the line break converter for a given text format in the Administration panel > Site configuration > Input formats section (recommended).

The CKEditor installation and basic configuration process is now finished. You can start to use CKEditor with its default settings on your Drupal 6 website.
