Q: How can I get rid of that pesky but persistent 'Revision Information' settings section from the create & edit content forms in Drupal 6?

A: You just need to hook into the phptemplate_node_form() function and disable the field - just a bit of PHP required!

In Drupal, the forms for creating and editing content can be very busy and cluttered with all sorts of options that may be completely irrelevant to your current web development project. Most can be removed if necessary by setting the appropriate permissions, but there is no easy way to remove the 'Revision Information' & 'Log Message:' stuff through changing settings. Now I am not a web designer myself but I do know that having fields hanging around that aren't required is not a good web design ploy! (isn't that right Shane?)

Well, there is a quick hack to make it go away, this method is frowned upon by some but it is quick, easy and it works very very well - needs must when the devil drives and all that!

So, to get rid it from your web application (in Drupal 6), edit the template.php file in your theme's folder and insert the following function:

function phptemplate_node_form($form)
{
$form['revision_information']['#access'] = FALSE;
return theme_node_form($form);
}

Save the file, and then visit the 'Modules' admin page in Drupal's Administration section, that will force Drupal to reload your recent change..

Now when you create or edit a content type the forms should be blissfully clear of any 'Revision Information' section!
