I want to execute PHP code when text is clicked (using HREF). I know I
can embed PHP code in the HREF, but that is 'executed' when the screen
is painted, not when the link is clicked.
My objective is to display a list of items, then set a session
variable with the value of the clicked item, before redirecting to
another page.
Is there anyway of doing this or another method ? I want to stick with
PHP and no JavaScripting. 6 3605
The only way I can think of is posting to another (hidden?) frame

It's executed before the content is sent to the client. All the client
will get is pure HTML, at this time PHP is long gone.
My objective is to display a list of items, then set a session variable with the value of the clicked item, before redirecting to another page.
Call the same page with an URL-parameter with the number of the selected
item, then let PHP insert it into the session and redirect or something
else, e.g.
<ul>
<li><a href="foo.php?item=1">Item 1</li>
<li><a href="foo.php?item=2">Item 2</li>
<li><a href="foo.php?item=3">Item 3</li>
</ul>

You can't embed PHP code in the HREF!
PHP runs before anything is displayed on the screen. The client will
just get pure HTML.

Why don't you set the session data on the target page?

The usual way to do this is to have the link go to a PHP script that sets
the session value and automatically redirects the visitor to their
destination. See the documentation on header() for how to do a redirect.

Thanks for your help guys, I have written a generic session
setting/redirection script that does the job.
One point though, PHP code can be embeded in an HREF, it is just
'fixed' when the HTML is written. ti*********@mail.com (Tim) wrote: Thanks for your help guys, I have written a generic session setting/redirection script that does the job.

Right. More accurately, the text that gets sent to the browser never
includes PHP code. By the time the link gets clicked, all traces of PHP
are gone.
