How Can I Check if a Checkbox is Checked in PHP?

Determining the Checked Status of a Checkbox in PHP

Your query revolves around determining whether a checkbox is checked when the form it belongs to is submitted. To accomplish this, you'll utilize the "isset()" function or the "if" statement.

If your HTML markup contains the following checkbox:

<input type="checkbox" name="test" value="value1">

After the form is submitted, you can verify the checked status using:

isset($_POST['test'])

This checks if the "test" checkbox is present in the $_POST array, indicating that it was checked. Alternatively, you can use the "if" statement:

if ($_POST['test'] == 'value1') ...

This checks if the value of the "test" checkbox matches the value you specified in the HTML ("value1"). If it does, it implies the checkbox was checked and you can proceed with the necessary actions.
