Question

My HTML code:

<p>NEWS</p>
<p>
    <form action="news.php" method="post"> <center><input name="NEW" type="submit"
    id="new" value="NEW"/>
        <input name="Modify" type="submit" id="Modify2" value="Modify" />
    </form>
</p>

news.php

<?php  //Main function
    $event=$_POST;
    if($event=='NEW')
        post_new(); //already defined   
    else if($event=='Modify')
        modify();//already defined
?>

post_new() and Modify() are already defined in the document.

What I intend to do is check which button has been clicked on the first page and invoke the functions accordingly but I don’t know where I am wrong because its not working. Please help, thanks in advance.. 🙂

$event (and $_POST) is an array. Use it like this:

<?php  //Main function
    $event=$_POST;
    if(isset($event['NEW']))
         post_new(); //already defined   
    else if(isset($event['Modify']))
         modify();//already defined
?>
