href an require_once


Recommended Posts

Can anyone tell me why this won't work?

<a href="<?php require_once('includes/scotch_gard.php'); ?>">Scotchgard Carpet Protector</a>

I want it to just display the link text and run the 'require_once' statement when I click it.

require and include (the their "_once" cousins) bring the code from the specified file into the current file as if you had typed that code right there. If that code outputs anything then the output appears right there.


PHP is run on the server, and all of its output is sent to the browser. The browser then renders the (usually) HTML to show the page to the user. If you want that script to be run when the link is clicked, then the link needs to point to a URL that will execute that script.
