Changing php variables using the href tag

Cool, looks good DJ. Thanks!

One thing though. Before i saw the javascript way you've shown (which would solve this problem), I was trying out a bit more of php and came accross a problem that is bugging me.

Code:

$ThisCategory=$_GET['Category'];
$Category = $ThisCategory;
$ThisPicture=$_GET['Picture'];

echo "<img src='images/$ThisCategory/$ThisPicture' width='353' height='280' alt=''></td>"  ;

On the left side of the page are links (Family, friends, places, etc..) and at the top are more links. What i wanted was for the user to click a link on the right and the $ThisCategory will be set, then the user will click on one of the links at the top of the page (Each numbered 01, 02, 03 etc..) and the $ThisPicture will be set, so i can pull only the pictures for that category.

Code:

<a href='http://localhost:8080/Website.php?Category=Photoshop'>

Is the link to set the Category field.

Code:

<?php
echo "<a href='http://localhost:8080/Website.php?Category=$ThisCategory?Picture=01.jpg'>";
?>

Is used for the 01, 02, 03 etc.. links at the top. However, I can't seem to keep the value of $ThisCategory? What am I doing wrong? Its just something i need to know.

sorry, got a bit of the code above wrong.

Code:

echo "<a href='http://localhost:8080/Website.php?Category=$ThisCategory&Picture=01.jpg'>";

Is what it should have been.

Also, Its worth mentioning again that i'm linking to the same page so in effect refreshing it. Thats why i cant figure out how to keep the value of $ThisCategory, otherwise it would be fairly simple.
