How to Hide Node Titles in Drupal 6?

In the page.tpl.php file of your theme look for the follwing code-snippet:

....................

<?php print $breadcrumb ?>
    <h1 class="title"><?php print $title ?></h1> 
    <div class="tabs"><?php print $tabs ?></div>

.........................
Change the line with class="title" into:

<h1 class="title"><?php if ($node->nid == node_number_of your_page) {print $title;} ?> </h1>

and substitute in the above your actual node-number for: node_number_of your_page.
The title is then only displayed on that page. Of course you could extend the condition of the 'if'-statement to include/exclude other nodes.

You can use this module: http://drupal.org/project/auto_nodetitle

It's possible for any module to change the variables that get sent to different template files using the hook_preprocess_HOOK function. For the page title we need to be changing the variables that are part of the template_preprocess_page function. So if we want to affect the page title through a custom module we need to create a function called hook_preprocess_page (and replace that first 'hook' with our module name of course!).

Let's pretend we've created a module called persistent_title.module. Here's the code we'd need to add:

/**
 * Implementation of hook_preprocess_HOOK()
 */
function persistent_title_preprocess_page(&$variables) {
  // Make every page title on the site say "Foo"
  $variables['title'] = 'Foo';
}

If we only wanted the title to be changed on certain paths we need to add some code that checks for the condition we want:

/**
 * Implementation of hook_preprocess_HOOK()
 */
function persistent_title_preprocess_page(&$variables) {
  // Remove the page title for certain target paths.
  $targets = array('some/path', '321');
  $path = $_GET['q'];

  // Make the title blank for pages on the matched paths
  if ( in_array($path, $targets) ) {
    $vars['title'] = '';
  }

}

isn't there an easy way to hide the node title by using an in line css override? so not to have to edit any files.

I have been trying to get rid of the post-headers from my website but no such luck. (http://drupal.org/node/759100)
And also i don't want to have that post-header on any of my pages, old or new ones, they all shall be clean from it.
So i tried the CSS you supplied and changed h1 to h2 and placed it in the end of the themes CSS sheet, but sadly, no joy.

Shouldn't it actually work? it seems to me as it´s kinda the same principle.
Do any of you suggest any other ways to get rid of the annoying post-header?
Any input what so ever is appreciated.

Best regards

When elements with display: none contain actual content that can be considered as relevant by search engines, it could damage your SEO (often used as blackhat technique).

.node-type-page h1.title {display:none;}
