Create order from Contact Form 7 dropdowns?

I thought of a different way to possibly pull this off.

I have my CF7 form automagically register new users with the role “Pending” assigned to them on submit.

Perhaps I can use CF7’s wpcf7_before_send_mail hook to capture dropdown data and save the selections (product IDs) to the update_user_meta array, and simply get_user_meta to build the URL string when the user logs in and goes to the checkout page.

This would keep it entirely as a PHP function, avoiding any JS, which would require passing variables from JS to PHP (e.g., via cookie).

As I have restricted the checkout page to approved users, this would take care of the checkout only after approval requirement.

Of course, even if I get that to work, it does nothing to resolve the issue of admins not being able to modify the order prior to checkout.

I coded this for a CF7 combination dance school class enrollment & website account registration form. This snippet obviously goes inside a larger function.

Doing it this way avoids using global variables, and besides, I couldn’t get $id = $product->get_id(); to work anyway (nor did wc_get_product_id_by_sku, nor any of the MANY variations and schemes I tried. The ONLY thing that works in my case is to associate known product IDs with CF7 dropdown options. I presume it’s due to this being in a function (CF7 wpcf7_before_send_mail) that doesn’t hook into WC. <shrugh>
Thus, this snippet doesn’t get product IDs. But, for those who know the product IDs (anyone with WC backend capabilities), it works just fine.

Minor loop nesting is involved. I had considered looping the $_POST values, but it would require about the same number of lines. If you have a lot of dropdowns, looping may be preferable.

This does not take multi-select into account, since this school only allows the student to enroll in a single class per season.

// Create WC order from CF7 dropdowns

$class_pick = array( // 5 student enrollment slots available per form
   $_POST['Dancer_1_Class'], // use $_POST instead of $posted_data to get raw dropdown data
   $_POST['Dancer_2_Class'],
   $_POST['Dancer_3_Class'],
   $_POST['Dancer_4_Class'],
   $_POST['Dancer_5_Class']
);
$classes = array( // 4 classes available to each dancer, 1 choice per dancer
   'Class 1: $100' => 1001, // associate product id (value) with dropdown option (key)
   'Class 2: $200' => 1002,
   'Class 3: $300' => 1003,
   'Class 4: $400' => 1004
);
$order = wc_create_order();
foreach ( $class_pick as $selection ) {  // match class with dropdown selection
   foreach ( $classes as $class => $id ) { // get product id from $classes array
      if ( $selection == $class ) {
         $order->add_product( wc_get_product( $id ), 1 );
      }
   }
}
$order->set_address( $address, 'billing' ); // insert billing array data which also dumps into customer account meta (not shown)
$order->calculate_totals();
$order->update_status("Completed", 'New User Created', true);

Some readers may be wondering why I didn’t nest a third loop to account for repeats (more than 1 student enrolling in the same class). Not doing so will make it easier for my subadmins to look at the order and know which line belongs with which dancer – e.g., if dancer 2 and dancer 4 are both enrolling in class 3, the order would show x2 for product 1003, but would not specify which of the 5 dancers that product belongs to, only that it wasn’t dancer 1. The subadmins will have these specifics via CF7 email and separate database to look at, but I may as well make it less confusing for them while they’re in the WC orders.
