Help with <a href

warrenaldo

Simple enough problem.

I have a long list of values - that can be filtered via links I have on the side of the page. Such as Sex and Married.

My starting url is www.example.com
A link is clicked - www.example.com?type=male
A further link clicked - www.example.com?type=male&married=true

My problem is when i click the further link - it says:
www.example.com?married=true

Its overwriting my curent params.

Please help.

Are you using & in the parameters, not just & on its own?

It's not "overwriting" any current params; the current params apply to the current page, and any links on that page that you want to "pass on" those params to another page need to do exactly that.

Alternatively, you can set those params in session variables.

Im not using session variables.

But i think im a bit clearer now.

I need to use Javascript - I dont know what order the user will click the params
type=male&married=true
or
married=true&type=male
So i cant pre-define the url.

I am always redirecting them back to the one page and changing content based on the url.

Not sure if i'm interpreting the prob correctly (should'nt be any difficulty passing multiple variables in the URL), but if you've got the option to use PHP here you could use a 'get' on the receiving page (even if it's the same page), eg:

<?php
if (isset($_GET))
{$male = ($_GET);}

if (isset($_GET))
{$married = ($_GET);}
?>

and if you need to pass back to javascript, something like this might do it:

<script language="javascript" type="text/javascript">
var $param1 = <?php echo $male ?>";
var $param2 = <?php echo $married ?>";
</script>

Might be other/better ways, but just a thought.

So i cant pre-define the url.

The order doesn't matter as long as both are set when required.

Simple version (piggybacking on jQuery):

$("#sexListname a").each(function() {
thisLink=this.attr("href").split("?")[1];
thisPage=document.location.href;
if (thisPage.indexOf(thisLink)==-1) this.attr("href",thisPage+"&"+thisLink);
});

Needs extra work to be robust, but might help get you started.
