Example: How to pull values during checkout workflow and trigger conditional panes

>>> [!note] Migrated issue   Reported by: [jmomandown](https://www.drupal.org/user/1844552) >>> Conditional Panes are asked about quite extensively in the Drupal Commerce Issue Queues. We should provide an example of how to pragmatically execute conditional panes based on a user input. The following is the code to disable panes from view: <pre><?php function my_module_commerce_checkout_pane_info_alter(&$checkout_panes) {     global $user;     // load current order     $order = commerce_cart_order_load($user->uid);         foreach ($checkout_panes as $pane_name => &$pane_data) {                     // override the unneeded pane             if ($pane_name == 'pane_to_override' && $pane_data['enabled']) {                 $pane_data['enabled'] = 0;                             }         }     } ?></pre>We should provide examples to users of how to use this in more complex situations. You see this referred to a lot in the context of shipping. Some products require shipping information and some don't. This is generally done by creating multiple products and then using the selected product to determine what panes should be displayed. However to allow for more complexity and promote strategies that are easier to maintain (not having 100's of products), we should show how to base this on a users choice during checkout. This could be something simple like asking a customer if they would like to add/extend their purchase in mid-checkout and collecting that information on the spot in a conditional pane. A simple example would be an event registration where during checkout you allow the user to addon dinner reservations should they choose. If they choose select yes then the registration pane shows, ect. I would envision this done in a way similar to the following, with switch statements allowing for more complex set ups where they are multiple panes for different selections: <pre><?php function my_module_commerce_checkout_pane_info_alter(&$checkout_panes, $form, &$form_state) {     global $user;     // Get Selected Value from field in Pane that belongs to the Orders entity     // If X value is selected then disable X pane     if ($form_state['values']['my_field'] == 'disable_value') {         foreach ($checkout_panes as $pane_name => &$pane_data) {             // load current order             $order = commerce_cart_order_load($user->uid);                                  // override the unneeded pane             if ($pane_name == 'pane_to_override' && $pane_data['enabled']) {                 $pane_data['enabled'] = 0;                             }         }     } } ?></pre>
