Hello Lode,
I am assuming your are using dropdown view of category which allow only one category to be selected. Try the following code:
add_filter( 'bblpro_validation_errors', function ( $errors, $data, $prepared_post_data, $form_id ) {
if ( ! function_exists( 'bbl_ppp_form_has_paid_posting_enabled' ) || ! bbl_ppp_form_has_paid_posting_enabled( $form_id ) ) {
return $errors;
}
if ( is_wp_error( $errors ) && $errors->has_errors() ) {
return $errors;
}
// Do not validate if save draft action.
if ( isset( $data['action'] ) && 'bblpro_save_draft' == $data['action'] ) {
return $errors;
}
// Replace with your taxonomy.
$tax = 'category';
$taxonomy = get_taxonomy( $tax );
$term_data = isset( $data['tax_input'] ) ? wp_unslash( $data['tax_input'] ) : array();
$selected_term = isset( $term_data[ $tax ] ) ? absint( current( $term_data[ $tax ] ) ) : 0;
$selected_product_id = isset( $data['bblpro_ppp_product_id'] ) ? absint( $data['bblpro_ppp_product_id'] ) : 0;
if ( empty( $selected_product_id ) || empty( $selected_term ) ) {
return $errors;
}
/**
* array (
* product_id => category_id
* )
*/
$product_category_mapped_ids = array(
5 => 16,
6 => 18,
);
if ( ! isset( $product_category_mapped_ids[ $selected_product_id ] ) ) {
// what should we need to return here. If selected product not in mapped array.
return $errors;
}
if ( $product_category_mapped_ids[ $selected_product_id ] != $selected_term ) {
$errors->add( "bbl_tax_$tax", sprintf( __( '%s is invalid. Please select matched with selected product', 'buddyblog-pro' ), $taxonomy->labels->singular_name ) );
}
return $errors;
}, 20, 4 );
Note: Please replace taxonomy and mapped product and term id array as per your configuration. Please give it a try. Please make sure the product and category field is required.
