    Question changing the value of a $_post or something?

    Hi,

    I am trying to get it so that when it echos out the message, it will echo out instead of FN, First Name.

    I dont want it to change FN as i still want to reffer to it as $_POST[FN];, i just want $key to say a different name, perhaps there is a way i can create an asigned name or tempery name.

    Here is my code
    PHP Code:
    <?PHP

    if ($_GET[validate] == 1) {
        
        foreach(
    $_POST as $key => $val) {
            
    // make sure it is filled out
            
    if (empty($val)) {            
                
    $error_msg "$key must be filled in.\n";
                
    $errors true;
            }
        }
    }

    ?>
    <html>
    <body>
    <!-- Page Errors -->
    <?php if(isset($errors) && $errors){ ?> 
    <?php echo $error_msg; } ?>

    <form method="post" action="<?PHP $_SERVER['PHP_SELF']; ?>?validate=1">
        <input name="FN" type="text">
        <input name="" type="submit" value="Submit">
    </form>
    </body>
    </html>
    Any ideas

    Thanks
    Adam

    Riiight, I think this is what you're getting at:
    PHP Code:
    <?php
    //Form an array of descriptions for each field
    $desc['FN'] = 'first name';
    $desc['LN'] = 'last name';
    //Your thing again
    foreach($_POST as $key => $val) {
    if (empty(
    $val)) {            
    $error_msg "$desc[$key] must be filled in.\n";
    $errors true
    ?>
