Hi!

Im creating a search engine for products.
it can search by category, model_no and so on..
when i searched for multimedia, it would return lists of products under multimedia.
every result should be clickable and would display info for each product.
problem is, how can i pass the value of the clicked link to another page, so that it will know what link was clicked? i have codes on how to do it , but it is in javascript. now i need to combine javascript and PHP.my lightbox javascript codes doesnt work inside php as well.

here are my codes:

<html>
<head> <title></title>
<!--link code -->
<SCRIPT>
function getLinkText (link) {
return link.text ? link.text :
link.innerText ? link.innerText :
link.firstChild.nodeType == 3 ? link.firstChild.nodeValue :
'';
}
</SCRIPT>
<!--end of link codes -->


<!--lightbox codes -->
<script type="text/javascript" src="js/prototype.js"></script>
<script type="text/javascript" src="js/scriptaculous.js?load=effects"></script>
<script type="text/javascript" src="js/lightbox.js"></script>

Solution:

#1 Catch the clicks

Since you're using prototypejs check out these examples how to handle clicks

http://www.prototypejs.org/api/event

Example:

$('foo').observe('click', respondToClick);

function respondToClick(event) {
  var element = Event.element(event);
  element.addClassName('active');
}

#2 React

You could save the clicked url in a cookie and access it from PHP later.

lordspace,
Thank you very much for your response.
that's what im trying to do actually,
im getting the text value of the clicked link and save it in a cookie, and then i'll access it in the php later.but the problem is, i cant insert the <a href="#" on click =blahblah> of javascript inside print ("") of PHP.
is it possible or i just have wrong syntax?
