How to read if a checkbox is checked in PHP?

Answer 1

I've been using this trick for several years and it works perfectly without any problem for checked/unchecked checkbox status while using with PHP and Database.

HTML Code: (for Add Page)

Hint: remove "checkbox" if you want to show it as unchecked by default

HTML Code: (for Edit Page)

>

PHP Code: (use for Add/Edit pages)

$status = $_POST['status'];
if ($status == 1) {
$status = 1;
} else {
$status = 0;
}

Hint: There will always be empty value unless user checked it. So, we already have PHP code to catch it else keep the value to 0. Then, simply use the $status variable for database.
