Make Regex Negative

[doubledee]

How do I reverse the logic of my Regex statement so it says, "If there is NOT a match..."

// (Replacement for non-supported Email-Filter.)
if (preg_match('#^[A-Z0-9_\+-]+(\.[A-Z0-9_\+-]+)*@[A-Z0-9-]+(\.[A-Z0-9-]+)*\.([A-Z]{2,7})$#i',
	$trimmed['senderEmail'])){
	// Valid Email.
	// ???
}else{
	// Invalid entry.
	$errors['senderEmail'] = 'Please enter a valid E-mail address.';
}// End of VALIDATE ENTRY.

 

I want to do this so I don't have an empty THEN statement!

function check_email_address($email) { // First, we check that there's one @ symbol, and that the lengths are right if (!ereg("^[^@]{1,64}@[^@]{1,255}$", $email)) { // Email invalid because wrong number of characters in one section, or wrong number of @ symbols. return false; } // Split it into sections to make life easier $email_array = explode("@", $email); $local_array = explode(".", $email_array[0]); for ($i = 0; $i < sizeof($local_array); $i++) { if (!ereg("^(([A-Za-z0-9!#$%&'*+/=?^_`{|}~-][A-Za-z0-9!#$%&'*+/=?^_`{|}~\.-]{0,63})|(\"[^(\\|\")]{0,62}\"))$", $local_array[$i])) { return false; } } if (!ereg("^\[?[0-9\.]+\]?$", $email_array[1])) { // Check if domain is IP. If not, it should be valid domain name $domain_array = explode(".", $email_array[1]); if (sizeof($domain_array) < 2) { return false; // Not enough parts to domain } for ($i = 0; $i < sizeof($domain_array); $i++) { if (!ereg("^(([A-Za-z0-9][A-Za-z0-9-]{0,61}[A-Za-z0-9])|([A-Za-z0-9]+))$", $domain_array[$i])) { return false; } } } return true; }

And since you're using PHP, maybe:

 

if(!filter_var($trimmed['senderEmail'], FILTER_VALIDATE_EMAIL)) {
