我正在尋找一種如何使用 Wordpress php 腳本執(zhí)行多個 sql 任務(wù)的方法。到目前為止，我有以下功能，但它不會執(zhí)行所有任務(wù)。private function rename_products($product) {    global $wpdb;    // Replace product names and descriptions    $sql = "UPDATE wp_posts SET post_title = REPLACE(post_title, 'Velikost Osu?ka', 'Osu?ka, Velikost');";    $sql = "UPDATE wp_posts SET post_title = REPLACE(post_title, 'Velikost Ru?ník 50x100Velikost Ru?ník 50 x 100', 'Ru?ník, Velikost 50x100');";    $sql = "UPDATE wp_posts SET post_content = REPLACE(post_content, 'Velikost Ru?ník 50x100Velikost Ru?ník 50 x 100', 'Ru?ník, Velikost 50x100');";    $sql = "UPDATE wp_posts SET post_excerpt = REPLACE(post_excerpt, 'Velikost Ru?ník 50x100Velikost Ru?ník 50 x 100', 'Ru?ník, Velikost 50x100');";    $wpdb->query($sql);}有任何想法嗎？
