PHP $_POST array for unchecked checkboxes
<p>If I have a form with two checkboxes that have have the same array as name attribute </p>

<blockquote>
  <p>name="1_1[]"</p>
</blockquote>

<p>and neither of those checkboxes is ticked, is there any way I can know they were present in the form? These fields are not being sent through the $_POST array if they are unchecked.</p>

<p>I'm asking this cause these name values are being generated dynamically, I don't always know what they are and I have to validate them (make sure at least one of the two is checked).</p>

<p>Do I have to start using hidden fields to send the name attribute values through, or is there a better way?</p>
