Function Call from Hyperlink Onclick (with parameter)

    I want to call a function in a separate .php file when I click on a hyperlink (href is NOT php file). My .htm code looks something like this:

    (I'm testing the code with <h1> or else I won't see the server's response.)

    <html>
    <body>
    <form name="coolform" method="get" action="test.php?q=PRE_SET_PARAM">
    <h1 onclick="document.coolform.submit()">
    Random Destination
    </h1>
    </form>
    </body>
    </html>

    And test.php looks like this:

    <html>
    <body>
    <?php
    echo $_GET['q'];
    ?>
    </body>
    </html>

    My only guess as to why this doesn't work is that it looks for test.php?q=PRE_SET_PARAM instead of test.php because ?q= can only be added at submission.

    How can I pass variable q to test.php

    That should work, but you could also try using a hidden named q.

    
<html>
<body>
<form name="coolform" method="get" action="test.php">
<input type="hidden" name="q" value="PRE_SET_PARAM" />
<h1 onclick="document.coolform.submit()">
Random Destination
</h1>
</form>
</body>
</html>
    HTML:
    Does the form currently submit at all. I didn't think that an h1 onclick is supported by every browser. You may need to format a submit button to look text if it isn't well supported.
