[PHP] $PHP_SELF in a template problem, I think ??

[Phil Latio]

I run a small search engine and adding URL's is a bit of a pain so I thought
I would try to make it easier. Looking around I found a PHP function called
"get_meta_tags" which unsurprisingly, grabs the contents of varoius meta
tags. I just want the "description" contents so I first made a standalone
PHP page (http://www.yorkshire-search.co.uk/links/meta-tags.php3) which
performs get_meta_tags and uses $PHP_SELF so output is displayed on a page
with the same name. Check it out and you see that works fine (was a slight
problem if no initial URL value set).

However, the search engine uses HTML templates and that is where my problem
is.

Within the orginal form (add_form.html) was just HTML so I deleted that and
put the above working code between <php></php> tags to generate a form.
WhenI uploaded it and then entered the page, the form displayed OK but when
I
press "generate meta tags" it refuses to output the results into the boxes.
The search engine manual says you can place PHP code within templates as
long as they are within <php></php> tags so I am now at a bit of loss.

This is the add_form.html template if anyone is interested.

if ($action == "generate")
{
print "<P>Insert the following HTML code between the &lt;HEAD&gt; tags of
your site:";
