I have a javascript widget that can be inserted on an a plain-old html page like this:

<html>
    <head>
        <script type='text/javascript' src="http://example.com/widget.js"></script>
    </head>
    <body>
        <script type='text/javascript'>
            //<![CDATA[            
            try{ widget_constructor('key',500,400); }
            catch(e){ alert(e.message); }
            //]]>
        </script>
    </body>
</html>

I would like to insert this javascript on one page of a Drupal 6 site (not every page).

This is what I have tried so far to get the script tag in the HEAD:

  • I set the Full HTML input format to allow php.
  • For the Drupal page, I set the input format to Full HTML

I then added this to the top of the body of my Drupal page:

<?php 
  drupal_set_html_head('<script type="text/javascript" src="http://example.com/widget.js"> </script>'); 
?>

But Drupal doesn’t parse the php and instead prints this at the top of the page:

<?php drupal_set_html_head(''); ?>

Any suggestions as to how I can do this?

    After writing that all out, I figured out the problem…

    The full html input format has an HTML corrector filter turned on by default, and that filter appears to have caused problems with the PHP code. Reordering the filters to put the PHP evaluator first fixed the problem.
