您好，我有一个问题可能比WordPress更像PHP问题，但在WordPress上下文中可能会很有趣，以防有人想向WP对象添加属性。

我创建了一个自定义分类法，并使用一个选项为每个术语添加顺序。

为了获得主题中的顺序，我使用了这两个函数：第一个函数检索术语，然后对它们进行排序：

    // SORT BY ORDER 
    function cmp( $a, $b ) { 
        if(  $a->order ==  $b->order ){ return 0 ; } 
        return ($a->order < $b->order ) ? -1 : 1;
    } 

    // FUNCTION TO INJECT ORDER ITEM IN TERM OBJECT
    function inject_order( $term_objects ) {
        if ( $term_objects ) {
            foreach ( $term_objects as $term_object ) {
                $term_id = $term_object->term_id;
                $term_order  = get_option( "taxonomy_term_$term_id" )[\'tax_order_nb\'];
                $term_object->order = $term_order;
                array_replace( $term_objects, $term_object );
            }
            return $term_objects;
        } else {
            return false;
        }
    }

    // FUNCTION TO GET CHILDREN TERMS AND ORDER THEM
    function get_children_and_order_terms( $term_id = \'0\' ) {
        $term_children = get_terms( \'category_effectif\', array( \'parent\' => $term_id, \'hide_empty\' => 0 ) );
        if ( $term_children ) {
            $term_children = inject_order( $term_children ); 
            usort ( $term_children, \'cmp\' );
            return $term_children;
        }
    }

我想纠正这个错误，让它变得更好。
