我做了另一个非常基本的插入查询，我想只插入一行3列。
public static function execute($params = null) // this is in my orm class, it does not extends or implements dpo or others so execute is not overrided
{
try
{
self::processParams($params);
self::$stmt = self::$mysql_conn->prepare(self::$query);
self::$stmt->execute(self::$bind_params);
return self::$mysql_conn->lastInsertId();
}
catch (PDOExecption $e)
{
$dbh->rollback();
return false;
}
}
用这个qúery：
private $add_pcategory = "INSERT INTO pcategories (id, name, active) VALUES (NULL, :name, :active)";
我有更多这样的查询，并且它们都使用相同的执行函数正常工作。
我找不到它的错误..用echo回答“嘿！” before ->execute()它不打印两次。所以执行只加载一次。
调用插入符号：

我无法想象什么是错的，添加产品作品，添加图片作品，添加pcategory插入2行而不是1行。
如果您不想搜索整个代码，请搜索：addProductCategory($categoryname)。
谢谢。
答案 0 :(得分：1)
我在启动时禁用了mysql start，手动重新启动，现在可以正常工作：D
