how to check if text from post field is 8 – 20 characters long? Is it done with strlen, and could you give me some example, please?

Answer 1

$variable = $_POST['your-field-name']; // or $_GET['']; depends on your post method

if(strlen($variable) > 7 && strlen($variable) < 21) {
 return true;
} else {
 return false;
}
