Bryan, you'll need to put a PHP if statement around the H1 tag. Basically, the statement would specify that if the do-not-display setting is turned off, the H1 tag will be loaded.

Glad you got it to work, and thanks for the kind words!

Unfortunately my method only works for nodes. There is however, an alternate method that can be applied to any page:

Add the following code to your template.php file (anywhere will do as long as you don't break up another piece of code), making sure to change any instance of 'magic' to the actually name of your own theme. Note that this name is the name of your theme's .info file, omitting the .info extension.

And then make sure you're page.tpl.php file's body tag looks like this:

<body class="<?php print $body_classes; ?>">

This will add relevant classes to the body tag about the content you're on. You can use these classes to create CSS style rules to hide h1 tags on specific pages.

Drupal's an awesome and very powerful CMS, but it can be pretty technically intensive (that's something they're trying to address with Drupal 7).

You need to use the .page-blog class as a parent to the h1. By adding the rule ".page-blog" set to hide, you're telling the page to hide any element that has the class "page-blog."

Here's what you need:

body.page-blog h1.title{
display: none;
}

Here's what that code specifies:
Set the display mode to hide for h1 elements with the class "title" that are child to (nested within) the body element with the class of "page-blog."

If the title is an h2, you'll have to replace h1 with h2 in the rule.

No problem and sounds good, haha. Good luck with your project.

That code right there just calls a variable called "title" and outputs it. Just wrap a span, h2, or div around your title code. Then just add the following PHP code in the class attribute of your HTML element that's wrapped around your title code:

<?php if(!empty($node->field_titlehide[0]['value'])) {$titlehide = $node->field_titlehide[0]['value']; print $titlehide;} ?>

Hey Dave,

You need to add the following code as a class to an HTML element surrounding the title:

<?php if(!empty($node->field_titlehide[0]['value'])) {$titlehide = $node->field_titlehide[0]['value']; print $titlehide;} ?>

Important things to remember:
1. This assumes your CCK field is titled "titlehide"
2. You still need to add the CSS rule to actually hide the element

Apart from that, that coding seems a bit sloppy.

First, the use of tables for layout is deprecated for a number of reason, primarily poor accessibility and lack of flexibility in CSS styling and layout. All layout should be done with spans and divs. Tables should really only be used for data/content.

Second, the php syntax is not correct. If you want to break up PHP conditional statements with HTML code, you should use this syntax:

<?php if(!empty($node) && $page == 0): ?>
<h1>your HTML code here</h1>
<?php else: ?>
<h1>some other HTML code</h1>
<?php endif; ?>

Curly brackets "{" should be used to declare what happens if a statement is true when you're using a continuous block of php code.
