我正在尝试从中批量添加自定义帖子类型的帖子。csv文件。除了两次添加帖子外，其他一切都正常。它们在数据库中完全相同，只是一个有作者1，另一个有作者2。此外，它在post\\u名称后面附加“-2”。以下是我所拥有的：

add_action(\'wp_loaded\', \'add_from_csv\', 10);
function add_from_csv() {
    if (($handle = fopen(dirname(__FILE__) . "/posts.csv", "r")) !== FALSE) {
        while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
            $term_1 = $data[0];
            $term_2 = $data[1];
            $term_3 = $data[2];
            $term_4 = $data[3];
            $term_5 = $data[4];
            $meta_1 = $data[5];
            $meta_2 = $data[6];
            $meta_3 = $data[7];
            $meta_4 = $data[8];
            $meta_5 = $data[9];
            $meta_6 = isset($data[10]) ? $data[10] : \'\';

            $post_id = wp_insert_post( 
                array(
                    \'post_title\' => $meta_1 . \' \' . $meta_2 . \' \' . $meta_3 . \': \' . $meta_4,
                    \'post_type\' => \'custom_type\',
                    \'post_status\' => \'publish\',
                )
            );

            if(!is_wp_error($post_id) || $post_id != 0) {
                $tax_1_terms = array($term_1, $term_2, $term_3, $term_4);
                wp_set_object_terms( $post_id, $tax_1_terms, \'tax_1\' );
                wp_set_object_terms( $post_id, $term_5, \'tax_2\' );

                update_post_meta($post_id, \'meta-1\', $meta_1);
                update_post_meta($post_id, \'meta-2\', $meta_2);
                update_post_meta($post_id, \'meta-3\', $meta_3);
                update_post_meta($post_id, \'meta-4\', $meta_4);
                update_post_meta($post_id, \'meta-5\', $meta_5);
                update_post_meta($post_id, \'meta-6\', $meta_6);
            } else {
                echo \'There was a WP_Error when loading posts from csv!\';
                break;
            }
        }
        fclose($handle);
    }
}

我有一个插件本身。如果我没有设置“post\\u status”，并且它使用默认状态“draft”，那么就没有重复项。但当我设置“post\\u status”=>“publish”时，它会插入两次帖子。两个副本的状态均为“发布”。有人能帮我解决这个问题吗？谢谢

 // causes duplicates ---
//add_action(\'wp_loaded\', \'add_from_csv\', 10);

// no duplicates ---
//add_action(\'admin_notices\', \'add_from_csv\', 10);

function add_from_csv() {
    if (($handle = fopen(dirname(__FILE__) . "/posts.csv", "r")) !== FALSE) {
        while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
            $post_id = wp_insert_post( 
                array(
                    \'post_title\' => $data[0],
                    \'post_type\' => \'post\',
                    \'post_status\' => \'publish\',
                )
            );
            if(!is_wp_error($post_id) || $post_id != 0)
                echo "<pre>Added {$data[0]}</pre>";

        }
        fclose($handle);
    }
}
