[NEBEREIKIA]reikalinga PHP pagalba

Sveiki, noriu padaryti registraciją, ir dabar man iškilo problema, kaip saugiau prafiltruoti email adresą, kad liktų @ ir taškas. Kitus duomenis filtravau taip:

htmlspecialchars($kintamas,ENT_QUOTES);

ereg_replace("[^A-Za-z0-9]", "", $kintamas);

Bet tai el. pašto adresams netinka, nes pašalinami reikalingi ženklai.

Dėkui už pagalba iš anksto.

function isValidEmail($email){

return eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email);

}

Google "email regex pattern"

Gali nedekot ;)

Dėkui, reikės pamėginti

function isValidEmail($email){

return eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email);

}

Nuo PHP 5.0 eregi nebėra patartina naudoti, geriausias variantas šiuo atveju:

if (preg_match('^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,6}$', $email)) {
   echo "OK";
} else {
   echo "BAD";
}

pasitikrink su

 

filter_var('[email protected]', FILTER_VALIDATE_EMAIL);

o jis tinka apsaugai?

if (preg_match('^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,6}$', $email)) {

} else {
   echo "BAD";
}

Tiesa nepagalvojau. Šitaip atrodo gražiau :lol:

function is_valid_email($email)
{
if(preg_match("/[a-zA-Z0-9_-.+]+@[a-zA-Z0-9-]+.[a-zA-Z]+/", $email) > 0)
	return true;
else
	return false;
}

Dėkui pasinaudosiu šito.

if (preg_match('^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,6}$', $email)) {

echo "OK";

} else {

echo "BAD";

}

false rodo, nors ir teisingai įvedu
