How to understand if parameter is empty - bomi - 06-16-2019
Hi. For example i have a delete method in users controller. I want to if there is no parameter i should redirect the user.
For example these codes are not working. I am waiting advices.
PHP Code:
public function delete($incomingId)
{
if (empty($incomingId)) {
redirect(base_url());
}
}
PHP Code:
public function delete($incomingId)
{
if (!$incomingId) {
redirect(base_url());
}
}
PHP Code:
public function delete($incomingId)
{
if (!isset($incomingId)) {
redirect(base_url());
}
}
