Ok, All -

Here's another intersting one that might come in handy...

How do I append a search query?

Let's say I have a URL like this...

www.wibble.com/index.php?range=cars

I want to create a new link on the page which takes the current URL and extends it by adding...

&colour=blue

The result is a link which reads...

www.wibble.com/index.php?range=cars&colour=blue

I apreciate that I could just create a new search from scratch - ?range=cars&colour=blue - but in this instance I want to see if I can selectively add elements to the URL as I get deeper into the search.

Do-able?

Hi Perchpole,

You can use @$_SERVER["QUERY_STRING"] to get the search query for the current page. Use it like this:

<a href="?<?php echo @$_SERVER["QUERY_STRING"] ?>&colour=blue">

Does that help? Please let me know if you have any questions.
All the best,
Chris

Hi Perchpole,

If you need to construct an absolute URL, your code is the way to do it. If all you need is a relative URL, what I posted above is a little simpler.

If both of these links where found on the page http://example.com/hello/world.php?range=cars, they would both result in the browser going to the same address:

<a href="?range=cars&colour=blue">relative</a>

<a href="http://example.com/hello/world.php?range=cars&colour=blue">absolute</a>

I hope this helps. Please let me know if you have any questions.
All the best,
Chris
