In need of 'how to' for $_SERVER['QUERY_STRING']

[iggitme]

I need to determine if $_SERVER['QUERY_STRING'] contains ?p . (the question mark followed by a p) and if it does NOT, serve a set of javascript files, if it does, do NOT serve those javascript files inside a hardcoded header.

example

if ?p is not present include these

	<script type="text/javascript"  src="<? bloginfo('template_url')?>/css/jquery.js"></script>		
	<script type="text/javascript"  src="<? bloginfo('template_url')?>/css/interface.js"></script>

if ?p is present do not include them...

any help would be very appreciated

thank you

If its in the query string use the $_GET superglobal and test for it:

if(isset($_GET['[red]p[/red]'])){
do_something();
}

else{
do_something_else();
}

the QUERY_STRING value doesn't actually hold the ? (at least not in my experience). So you really want to see if the first 2 chars are p=

to determine if one string is inside another you would use the strpos function.

something like this:

if (strpos($_SERVER['QUERY_STRING'],'p=') === false) 
{
  $scriptBlock = '<script type="text/javascript"  src="' . bloginfo('template_url') . '/css/jquery.js"></script><script type="text/javascript"  src="' . bloginfo('template_url') . '/css/interface.js"></script>';
} else {
  $scriptBlock = '';
}
echo $scriptBlock;

I'm using === in the comparison because if the p= was in the QUERY_STRING it would be at the first character which would return 0, which would also == false, but obviously 0 doesn't === false.

So, that should do it for you.

OR, you can use Vacunita's much simpler suggestion.

i would instead use wordpress's built in methods to enqueue scripts and stylesheets. it's always better to use the proper API's rather than use 'hacks' from within templates.
