Well I think the support is dead for this plugin, but I have an answer if somebody else is trying to implement this:
functions.php, Line 325
case ‘dropdowns’ :
$form.='<p><select name=”av_verify_m” id=”av_verify_m”>’;
$form.='<option value=”” disabled selected>Month</option>’;
foreach ( range( 1, 12 ) as $month ) :
$month_name = date( ‘F’, mktime( 0, 0, 0, $month, 1 ) );
$form .= ‘<option value=”‘ . $month . ‘”>’ . $month_name . ‘</option>’;
endforeach;
$form .= ‘</select> – <select name=”av_verify_d” id=”av_verify_d”>’;
$form.='<option value=”” disabled selected>Date</option>’;
foreach ( range( 1, 31 ) as $day ) :
$form .= ‘<option value=”‘ . $day . ‘”>’ . esc_html( zeroise( $day, 2 ) ) . ‘</option>’;
endforeach;
$form .= ‘</select> – <select name=”av_verify_y” id=”av_verify_y”>’;
$form.='<option value=”” disabled selected>Year</option>’;
foreach ( range( 1910, date( ‘Y’ ) ) as $year ) :
$selected = ( $year == date( ‘Y’ ) ) ? ‘selected=”selected”‘ : ”;
$form .= ‘<option value=”‘ . $year . ‘”>’ . $year . ‘</option>’;
endforeach;
$form .= ‘</select></p>’;
break;
