我尝试使用 PDO,但结果为 1,1,1,但数据库不会更新。我不知道我的代码有什么问题。
try {$db = new PDO("mysql:dbname=$db_name;host=$db_host", $db_user, $db_pass );}
catch(PDOException $e){echo $e->getMessage();}
$title_insert = $db->prepare("UPDATE topics SET topic_title = ? WHERE id = ?");
$title_insert->bindParam(1, $id);
$title_insert->bindParam(2, $topic_title);
$tag_insert = $db->prepare("UPDATE topics SET topic_tags = ? WHERE id = ?");
$tag_insert->bindParam(1, $id);
$tag_insert->bindParam(2, $topic_tags);
$story_insert = $db->prepare("UPDATE topics SET topic_story = ? WHERE id = ?");
$story_insert->bindParam(1, $id);
$story_insert->bindParam(2, $topic_story);
$id = 1;
$topic_title = "title";
$topic_tags = "tags";
$topic_story = "story";
$result_title = $title_insert->execute();
echo $sonuc_title.',';
$sonuc_tag = $tag_insert->execute();
echo $sonuc_tag.',';
$result_story = $story_insert->execute();
echo $result_story;
感谢您的回答...
最佳答案
您是否尝试过切换参数编号?
$title_insert = $db->prepare("UPDATE topics SET topic_title = ? WHERE id = ?");
$title_insert->bindParam(1, $topic_title);
$title_insert->bindParam(2, $id);
祝你好运!
