Retrieve Form 'image ids' after submission

How To
1

Hello,

I have a form that uploads images. i want have them added to postmeta ‘images’ automatically
ive tried a few option and Eric on FB mentioned ‘bricks/form/response’ but i cant find any docs on it

From what ive seen with a custom message in another topic i have the following code. but i feel like this is too much and im missing something easier…

Any ideas would be appreciated… If theres a better way to publicly upload photos to a post im all ears

function my_form_custom_action($form) {
    $fields = $form->get_fields();
    $formId = $fields['formId'];

    // Ensure this matches your actual form ID
    if ($formId !== 'azovhw') {
        return;
    }

    // Retrieve the post ID from the URL
    $post_id = isset($_GET['post']) ? sanitize_text_field($_GET['post']) : '';
    error_log('Post ID from $_GET: ' . print_r($post_id, true));

    // Ensure the post ID is valid
    if (!$post_id || !is_numeric($post_id)) {
        error_log('Invalid or missing post ID.');
        $form->set_result([
            'action' => 'my_custom_action',
            'type'    => 'error', 
            'message' => 'Invalid post ID.',
        ]);
        return;
    }

    // Retrieve the form response
    $response = $form->get_response();
    if (isset($response['files']) && is_array($response['files'])) {
        $image_ids = []; // Array to store image IDs

        foreach ($response['files'] as $file) {
            if (isset($file['id']) && is_numeric($file['id'])) {
                $image_id = intval($file['id']);
                $attachment = get_post($image_id);
                if ($attachment && 'attachment' === $attachment->post_type && wp_attachment_is_image($image_id)) {
                    $image_ids[] = $image_id;
                } else {
                    error_log('File ID ' . $image_id . ' is not a valid image attachment.');
                }
            }
        }

        // Save image IDs to post meta
        if (!empty($image_ids)) {
            update_post_meta($post_id, 'images', $image_ids);
        }
    } else {
        error_log('No files included in the form response.');
    }

    // Set success result
    $form->set_result([
        'action' => 'my_custom_action',
        'type'    => 'success', 
        'message' => 'Images saved successfully.',
    ]);
}
add_action('bricks/form/custom_action', 'my_form_custom_action', 10, 1);


function my_custom_response($response, $form) {
    $results = $form->get_results();

    // Loop through success results and check for custom action
    if (isset($results['success'])) {
        foreach ($results['success'] as $result) {
            if ($result['action'] === 'my_custom_action') {
                $response['message'] = $result['message'];
                break;
            }
        }
    }

    return $response;
}
add_filter('bricks/form/response', 'my_custom_response', 10, 2);
