Update Feb. 2012

Removed underscore from name to support future releases of DokuWiki.

Download / Installation

Download and install the plugin using the Extension Manager. Refer to Plugins on how to install plugins manually.


As soon as the plugin is installed (and as long as it is not deactivated), the save button will be deactivated in edit mode. By clicking “Preview”, the user can activate the save button. this assures, that no unpreviewed content is saved into the wiki.

non-Javascript solution

Here is a solution without Javascript. The only problem with this solution is that you have to change the PHP code of the Dokuwiki files.

Edit the file inc/html.php, search for the following line (this is how it looks like in version 2009-02-14b).

$form->addElement(form_makeButton('submit', 'save', $lang['btn_save'], array('id'=>'edbtn__save', 'accesskey'=>'s', 'tabindex'=>'4')));

Add “if($pr)” in front of the line, it should look like this. (This shows the save button only when you have previewed the page - change the color if needed)

if($pr) $form->addElement(form_makeButton('submit', 'save', $lang['btn_save'], array('id'=>'edbtn__save', 'accesskey'=>'s', 'tabindex'=>'4')));

If you want to only disable the button without removing add this line below (the save button will be rendered but not clickable and grayed out)

else $form->addElement(form_makeButton('button', '', $lang['btn_save'], array('id'=>'edbtn__save', 'accesskey'=>'s', 'tabindex'=>'4', 'disabled' => 'true', 'style' => 'color: grey; cursor: default;')));
