问题描述

ajax和jquery的新手，我正在餐厅网站上工作。

我为餐饮订单创建了一个模态窗口。 om这个模态窗口我想添加两个文本字段用于选择和大小，以便修改客户餐饮订单。

我已经尝试了他的东西。但是没有得到确切的结果。



这里到目前为止我尝试了什么



我尝试过：



模态窗口



$ query = mysqli_query（$ con，SELECT * FROM users WHERE user_name ='。$ _SESSION ['user_name']。'LIMIT 1）或trigger_error（查询失败：。mysqli_error（$ con））;

$ query2 = mysqli_fetch_array（$ query）;



$ order_user_nice_name = $ query2 ['user_nice_name'];

$ order_user_email = $ query2 [user_email];

$ order_user_phone = $ query2 [user_phone];

$ user_delivery_address = $ query2 [user_delivery_address];

}
