PHP form validation submit problem?
- by TaG
My code is suppose to save a year like 1999 to the mysql database but it wont. It will check to see if the user has entered only numbers and is at least 4 numbers long or if nothing has been entered correctly but it wont save the correct year? How can I fix this problem.
Here is the PHP code.
if(isset($_POST['year']) && intval($_POST['year']) && strlen($_POST['year']) == 4) {
$year = mysqli_real_escape_string($mysqli, $purifier->purify(htmlentities(strip_tags($_POST['year']))));
} else if($_POST['year'] && strlen($_POST['year']) < 4) {
echo '<p class="error">year is not correct!</p>';
} else if($_POST['year'] == NULL) {
// do something
}
