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. |

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. |

| 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
}
?>

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
}
?>
