I can't figure out what I'm doing here. I admit I'm a bit of a newb.

I'm trying to have a script that checks the format of an email address, and then checks to make sure the domain has an mx record.

<?php

if ($emailaddress && $question){
        $emailaddress = $_POST['emailaddress'];
        $question = $_POST['question'];
}

print "$emailaddress\n\n";
print "$question\n\n";


if (!$emailaddress || !$question){
        print "<form action='/~Bryan/newtest.php' name='emailchecker' type='post'>
                        Email address: <input type='text' value='$emailaddress' name='emailaddress'>
                        Question: <br><br>
                        <textarea rows='6' cols='34' name='question'>$question</textarea>
                        <input type=submit>
                </form>
        ";
}

if (!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $emailaddress)) {
        echo "That email doesn appear to be formatted";
        exit;
}else{
        echo "that email is formatted correctly...";
}

list( $Username, $Domain )=split("@",$emailaddress);

if(getmxrr($Domain, $MXHost)){
        echo "and has an MX host.";
}else{
        echo "but the remote server doesn't have an MX host.";
}

?>

is it not working? or is something else wrong?

Butthead

no it's not working. The echo part I added to see what the variables are getting assigned but they don't echo anything. No matter what I type in for the email address, valid or not, it says invalid. I have a feeling it's because the varaibles are null... :-/

ok, well if register globals is disabled you will need to make a little change...

if ($emailaddress && $question){
        $emailaddress = $_POST['emailaddress'];
        $question = $_POST['question'];
} 
//needs to be changed to
if ($_POST['emailaddress'] && $_POST['question']){
        $emailaddress = $_POST['emailaddress'];
        $question = $_POST['question'];
}

with that change, it works fine for me.

Butthead

Great! got it! thanks.
