Multiple forms on one page handling multiple scripts

[markyoung1984]

I have three forms on a page. I want a different PHP function to handle each form. How can I do this?

Set the forms action to point to a different script, or send a flag through $_GET and check which form has been sent.

So in the end it'd be something like:

if (isset($_GET['form'])) {
    if ($_GET['form'] == "login") {
         formLogin();
    }
}

Alternatively, you could add hidden elements to each of the forms, like so:

<form action="script.php" method="post">
<input type="hidden" name="action" value="add">
...
</form>

<form action="script.php" method="post">
<input type="hidden" name="action" value="del">
...
</form>

<form action="script.php" method="post">
<input type="hidden" name="action" value="view">
...
</form>

And then you would simply check the value of this hidden element to do different things:

$action = (isset($_POST['action']) ? $_POST['action'] : '');

if($action == 'add') {

// do something

} elseif($action == 'del') {

// do something else

}elseif($action == 'view') {

// yet a different form...

} else {

// err... they did something wrong...
// redisplay form, possibly with error message?

}

Or.. you could just have the submit buttons named different things, i.e.

<input type="submit" name="submitDel" />

<input type="submit" name="submitAdd" />

And then do the same thing, just a little different with:

<?
if (!$_POST) {
    echo '<center><b>Error: </b>Form has not been submitted</center>';
} else if (isset($_POST['submitDel'])) {
     //process code
} else if (isset($_POST['submitAdd'])) {
    //process code
} else {
    echo '<center><b>Error:</b> Unknown Error</center>';
}
?>
