Testing if a link is clicked...

madcat

I have this bios link on a dynamic php menu...there are two bios under bios...what i want is to test and see if the bios button has been clicked...if so, i want two sub-menu links to appear below the bios link...

I understand I'll need to do an if...else here but how do I test to see if that bios link has been clicked?

Can you point me to where I could find this type of information on php.net too? Just don't know where to search- but will. Most appreciated!

PHP is server side. (Hang with me a minute, now....)

If you want to know if a link has been clicked with PHP, you have to do it intuitively. That is, you put a button in a form, or you create a link with the proper query string, and you write PHP code that handles this action on the server; either a handling script (for a form) or a dynamic script that reads query strings and acts appropriately.

So, it's quite possible that whatever it is you want to do (branching menus, sounds like) can be done with PHP.

But the subject of your post is "Testing if a link is clicked." There's a way to do this on the client side ... it's Javascript. You may want to think about that.

HTH,

I think it would be best to use PHP. My script would be something like this:

if (user clicks on link) {
show two new sub-menus
} else {
just show the one
}

Well, yes. You're no farther along that this, though?

Let's say the first page is "bios.php" and it has a list of possible bios.

<?php
echo "Choose a biography:<br><br>";
echo "<a href=\"show_bio.php?name=GW\">
George Washington</a>
<br><br>
echo "<a href=\"show_bio.php?name=BF\">
Ben Franklin</a>
<br><br>";
?>

//the second page is "show_bios.php"

<?php

if ($_GET['name']=="GW") {
   include 'washbio.html';
} elseif ($_GET['name']=="BF") {
   include 'frankbio.html';
} else {
   echo "Whom did you say?";
}
?>
