Options for advanced users
Save product configuration
An additional button "Save product config" is available on the product subpage. It is located above the "Add to Cart" button and it is visible only to the store administrator. The function enables sending to the customer ready product configurations (e.g. via email).
Clicking on the "Save product config" button will save the current configuration of a given product. The configuration will be available in the form of a URL in the browser bar (the address will appear after reloading the page).
Example of the button on the product page:
It is possible to hide the entire container with CSS. Please go to Appearance > Customize > Additional CSS and paste the code below.
div.fpf-fields-config-wrapper {
display:none!important;
}
Data storage location
Data of created product fields and their settings are saved in the database. They can be used for external integration or customization of the plugin.
Field group definitions
The Fields groups are saved in the posts table as fpf_fields. This post type has additional data in the postmeta table where you can find information about the name of the field and what can be entered inside of it. The record in postmeta will have _fields value entered in the meta_key field. In the post ID, you will find the post ID of the field group.
Field Values
The values of specific fields, i.e. data entered there by the user, are stored in the wp_woocommerce_order_itemmeta table. They are associated with a specific product by order_item_id and the definition of the specific meta_id field.
Getting the field values
The following code can be used to retrieve field values and use them in your functions.
Attention!! The scope of support does not include the development of individual functions, and modifying the source code of the theme is at your own risk.
$fields_by_product = [
// product id
368 => [
'Select', // FPF field label
],
];
// order id
$order = wc_get_order( 664 );
$items = $order->get_items();
$values = [];
foreach ( $items as $item ) {
$order_item_id = $item->get_id();
$product_id = $item->get_data()['product_id'];
if ( isset( $fields_by_product[ $product_id ] ) ) {
$values[ $order_item_id ] = [];
foreach ( $fields_by_product[ $product_id ] as $field_label ) {
$values[ $order_item_id ][ $field_label ] = wc_get_order_item_meta( $order_item_id, $field_label, true );
}
}
}
// ... $values
Change the label of the price field
It is possible to customize the labels that contain the brackets with the price. Paste the appropriate code into the functions.php file. Make a backup of the file before making these changes.
Adding a plus before a price greater than 0
add_filter( 'flexible_product_fields/field_args/label_price', function( $label, $price_raw, $field ) {
if ( $price_raw > 0 ) {
return '(+%s)';
}
return $label;
}, 10, 3 );
Removing the brackets
Paste the field name in place of the field name. The field name is in the field settings under the label name e.g. fpf_5801863.
add_filter( 'flexible_product_fields/field_args/label_price', function( $label, $price_raw, $field ) {
if ( $field['id'] === 'field name' ) {
return '';
}
return $label;
}, 10, 3 );
