Passing Session Data on an href link

[Mark Pacey]

Hi,
I have a web page that gets info from a mySQL database for various
items, and slaps that info, along with pics onto the page. ( in a
shopping site stylee) The pics have an href link, and I want just one
display page that all the pics refer to, so that any items pic and
info can be viewed on its own. I therefore need a way of capturing the
pic info into a session variable when the link is clicked, so that I
can pull the individual item back out on the display page. Any ideas
how I achieve it ??

Use information inside the URL (in $_GET, not in $_SESSION):

<a href="iteminfo. php?id=834"><im g src="pic834.jpg " alt="item 834"/></a>

When the user clicks this image the iteminfo.php script will run and you
can use $_GET['id'] to know what picture was clicked. You can put that
value in the session variables if you need it for other scripts.
