Clicky.

I know I can google it, I have done it before I am just confused by what google gives me. Which is why I resorted to coming on here and looking for additional help.

Then explain what part of it has you confused, or ask a specific question about it. When you ask a question like the one in the OP, that's about the best answer for it.

I guess I am just looking for a wording for php code that checks to make sure @ sign is there...( i do not even know how to check to make sure the input is a number) For instance I have another form where they have to enter a phone number and I have no way of checking whether they enter 10 digit number or 10 letters...

if(preg_match('/^[a-zA-Z0-9]+[a-zA-Z0-9_.-]+[a-zA-Z0-9_-]+@[a-zA-Z0-9]+[a-zA-Z0-9.-]+[a-zA-Z0-9]+.[a-z]{2,4}$/', $_POST['email1'], $matches) && strlen($matches[0]) === strlen($_POST['email1']))

 

Could be used like..

if(preg_match('/^[a-zA-Z0-9]+[a-zA-Z0-9_.-]+[a-zA-Z0-9_-]+@[a-zA-Z0-9]+[a-zA-Z0-9.-]+[a-zA-Z0-9]+.[a-z]{2,4}$/', $_POST['email1'], $matches) && strlen($matches[0]) === strlen($_POST['email1'])){
//codes to submit registeration
} else {
echo 'Your email isn't valid';
}

 

Of course, you'll have to edit the variables to match yours.
