In Drupal (considering v5.x here), the content page titles i.e. the text which is generated and put between <TITLE> HTML tag comes like this -

Content-Name | Site Name

Right ?

This doesn't look nice and it is not possible to remove this by editing a theme's file.

So here's a simple code change about how to remove this title internally so that whenever it is generated, it gets generated as

Content-Name

We're considering the default template engine - PHPTemplate which comes with Drupal.

You need to edit the file called phptemplate.engine file in /themes/engines/phptemplate directory.

Open the file your favourite editor.

Jump to Line 185 (As of Drupal 5.x)

$head_title = array(strip_tags(drupal_get_title()), variable_get('site_name', 'Drupal'));

Change the above line so that it looks like this -

$head_title = array(strip_tags(drupal_get_title()));

Save the file.

And copy this new file to /themes/engines/phptemplate/phptemplate.engine while backing up the older file.

And voila! you are done!
