Deny from free email address

[Anon]

Hi,

I have a product for download operation, so I want to deny using any free email addresses for order delivery.

I have a table (free_email) which will contain entries like: hotmail, yahoo, etc., without the .com or whatever.

When someone submits a form, I want to check their email address against this free_email table and deny all free email addresses on my list.

Something like this in reverse would work (free_email is both the name of the field and the table):

$sql = "SELECT * FROM free_email WHERE free_email Like '%$email%'";

This would be great if the table contained [e-mail] and they entered hotmail in the form.

How would I make it so they enter [e-mail], it checks the free_email table and sees the word hotmail, which I could then reject?

Thank you,
Mark

You could try something like this...

$invalid = Array('@.','@yahoo.');
if(preg_match($invalid,$email))
{echo "INVALID EMAIL<br>";}

Hope it helps

<?
//Hello you could try adding the "bad email addresses" to an array.

bademail = array("hotmail", "yahoo");

// If you've name the e-mail field email

for ( $i = 0; $i <= sizeof ($bademail); $i++) {
if ( stristr ($email, $bademail[$i]) )
{
echo "I don't like addresses with $bademail[$i] in them";
exit;
}
}
// If we got through the check will carry on with the script
echo "I like your mail address";
?>

Thank you for the help. Both examples work for me.

Mark:

use Al's suggestion. (Mike's would disallow addresses like [e-mail] or [e-mail].)
