I've created a formula that allows you to create such codes
12345-6789-101112
What I want now is, when I validate the form I want to verify that the code is correct for example.
Se contem 5(00000) em cada 3(00000-00000-00000).
Is there any way to do this?
One way is to use a regular expression to validate the specific format. % with% siginica that only letters (a-z) and numbers (0-9) will enter the capture.
$str = '12345-67819-10111';
$regex = '/^[a-z0-9]{5}-[a-z0-9]{5}-[a-z0-9]{5}$/i';
$valido = preg_match($regex, $str);
