In PHP, How Can I Determine If A Checkbox Has Been Checked?

To check if a checkbox is checked in PHP, you can use the isset() function to check if the checkbox value is submitted or not. Here’s an example:

HTML form:


PHP code (submit.php):

    // Checkbox is checked
    echo "Checkbox is checked.";
} else{
    // Checkbox is not checked
    echo "Checkbox is not checked.";

In the PHP code, $_POST['checkbox'] accesses the value of the checkbox input. If it is set, it means the checkbox is checked, otherwise it is not checked.
