How do I make an alert popup when a required field isn't filled in.
At the moment, info from my forms get sent even if the required fields aren't filled in.

PHP:

---

<?php if($_POST[feildname] == "") {
   echo "Your forgot to enter something in feildname";
}
?>

cool thanks..
does that bring up an alert box?

[webmaster]

No it only shows the text: You forgot to enter something in fieldname.

But just change what it should echo, you can add html code in there to.

so i can chuck javascript in the echo?

Yes, as far as I know the PHP will be compiled, outputting pure HTML. So if you chuck HTML/Javascript/whatever in it, it will be treated the same way as you were coding a page in plain HTML or Javascript.

 And to make it even easier you can end the php, write the javascript as you want and then start the php again. Like this:

PHP:

---

<?php if($_POST[feildname] == "") { ?>
   Standard HTML or Javascript here!
<?php
}
?>

but the info will still send though...how do i stop that?

[webmaster]

 If you set the name on the submit-button to: hello

PHP:

---

<?php

if(isset($_POST['hello'])) {
    if($_POST['url'] == "") { ?>
        You forgot the enter something in the url-field
    <?php
    } elseif($_POST['mail'] == "") { ?>
        You forgot the enter something in the mail-field
    <?php
    } else {
        echo "The url is: " . $_POST['url'] . " and the mail is: " . $_POST['mail'];
    }

} else { ?>

    <form method......
    ........................
    ........................
    </form>

<?php
}
?>
