This is almost certainly an incredibly easy to answer question, but I am struggling.

How do I modify the tag on a Drupal 6 page?

I want to integrate Google Earth, which requires a tag to be added to the page head. While this page[http://api.drupal.org/api/function/drupal_set_html_head/6] seems to describe what I want, I can't seem to make it happen...

Could anyone provide me with an example or direction to an example?

Thanks in advance for your time.

Is it a meta tag or something? Just open up page.tpl.php and paste it in.

Hi Jeff,

No, it's not a meta tag. It's a bit of JavaScript to initialise the Google Earth API (http://code.google.com/apis/earth/documentation/#using_the_google_earth_api) and I don't need to load it on every page. Just the one.

Any idea how I do that?

drupal_set_html_head will usually be ok when used in themeName_preprocess_page and set into the head variable, such as...

function themeName_preprocess_page(&$vars, $hook) {
  // only load this for node/36
  if (arg(0) == 'node' && arg(1) == 36) {
    $vars['head'] = drupal_set_html_head('<script src="http://www.google.com/jsapi?key=ABCDEF"></script>');
  }
}

..but, as dman points out this is only really ok if whatever you were loading was for that theme only; as soon as you change theme you loose critical functionality. Jamming everything in a node and using the PHP filter is better because at least that wont happen.

drupal_set_html_head probably is the one you need - if you are adding the feature through code.
A common problem is that using drupal_set_html_head() in your theme may not work because it's too late in the page building process.

I understand that you only want this to happen on one page, that's fair enough, but how do you plan on selecting that one page?

The very easiest way I see is to copy all the code you want into a normal node content area, as raw HTML, be sure to use 'unfiltered' input format, and it usually just works.
There's no huge difference between a script being inline or in the head.

But if you really want, you can use php input on your node, then call drupal_set_html_head() to add the script tag, and paste the other raw HTML in the content area too.

drupal_set_html_head('<script src="http://www.google.com/jsapi?key=ABCDEF"></script>');
drupal_set_html_head('<script>google.load("earth", "1");</script>');

etc. Note the google instructions require several more script steps...

Anything more clever than that, you should look at existing integration modules. This is not a theme job, so if you find yourself looking at them, it's probably the wrong thing to do. There MAY be a cheap & cheerful theme hack you can do, but it's the wrong place to be adding content functionality.
