In what scenarios would using a hidden input field alongside a checkbox be a suitable solution for handling checkbox values in PHP forms?

When dealing with checkboxes in PHP forms, a common issue is that unchecked checkboxes do not send any value when the form is submitted. To ensure that the checkbox state is always sent, you can use a hidden input field alongside the checkbox. This hidden input field will have a default value (e.g., 0) and will be overridden by the checkbox value (e.g., 1) if the checkbox is checked.

&lt;input type=&quot;hidden&quot; name=&quot;checkbox_name&quot; value=&quot;0&quot;&gt;
&lt;input type=&quot;checkbox&quot; name=&quot;checkbox_name&quot; value=&quot;1&quot;&gt;
