I need to disable an option once it reaches 16 users. I have a workshop sign up form, it lists a dozen workshops, but each can only host 16 participants.

However, you can try the method from me : 1. Edit "includes/view-functions.php" file and go to line 1831, you will see this text . <pre><code>//If you would like ......</code></pre> then put these code above that line <pre><code>if ($form_id == 11) { $query = "select sum(element_1_1) sum_1, sum(element_1_2) sum_2, sum(element_1_3) sum_3 from ap_form_{$form_id}"; $result = do_query($query); while($row = do_fetch_result($result)){ if ($row['sum_1'] > 2) { $disable_checkbox_1 = ' $("input#element_1_1").attr("disabled", true); '; } if ($row['sum_2'] > 2) { $disable_checkbox_2 = ' $("input#element_1_2").attr("disabled", true); '; } if ($row['sum_3'] > 2) { $disable_checkbox_3 = ' $("input#element_1_3").attr("disabled", true); '; } } $custom_js =<<<EOT <script type="text/javascript" src="js/jquery/jquery-core.js"></script> <script type="text/javascript"> $(document).ready(function() { {$disable_checkbox_1} {$disable_checkbox_2} {$disable_checkbox_3} }); </script> EOT; }</code></pre> 2. Go to line 1871 for this code <pre><code>{$calendar_js}</code></pre> and change it to <pre><code>{$custom_js} {$calendar_js}</code></pre> That would disable check box options, if it's selected more than 2. In there I assume your form id is 11 and the check box option is 1 (element_1_1,element_1_2,element_1_3). You need to change those id with yours. tobyp on "Checkboxes - php disable" https://www.machform.com/forums/topic/checkboxes-php-disable#post-12604 Tue, 20 Sep 2011 11:37:44 +0000 tobyp 12604@https://www.machform.com/forums/ Hi I'm using Machforms to create a booking system for a one day event with three sessions and a limited amount of places available for each session submitted from one form using a checkbox Checkbox1 - session1 - 9-12pm Checkbox2 - session2 - 12-1pm Checkbox2 - session3 - 1-5pm The client wants the checkboxes to be disabled as and when each individual session is booked out. Not being a programmer I've achieved it by using this db query on the php page that i have my embed code for the form . Then I've used a Javascript function to disable it and change the class on the label. This works ok but it's not ideal as it's clientside, is there anyway to do this with PHP? Thanks for your help. <code>$query = "SELECT COUNT(element_5_1) AS element_5_11 FROM ap_form_2 WHERE element_5_1='1' "; $result = do_query($query); $row = do_fetch_result($result); if ($row[0] >= 10) { echo 'there are equal or more than 10 entries in 9am-12pm'; echo '<script type="text/javascript">disableCbx1()</script>'; } </code>
