Question

我使用$ _POST来获取order_id的值，但它并没有立即得到安静。我需要先点击按钮“显示食物”或任何按钮（如下图所示）弹出我要输出的表格。我尝试使用if（isset（$ _ SESSION ['viewOrder']））来获取order.php中按钮的值，但即使我使用SESSION它也没有在ordermodal中获取它。如何获取按钮viewOrder的值？

如果我将WHERE order_id = $ order_id更改为WHERE order_id = 724，它将立即弹出该数字的值（724）但是它是食物表中所有订单的输出。所以我的问题是如何为特定的order_id输出正确的输出？

示例我有2个订单order_id 1和order_id 2，值1是汉堡和比萨饼，值2是沙拉和三明治，所以当我点击order_id 1（查看订单按钮在order.php）时的值食物表只是汉堡和披萨然后当我点击order_id 2（在order.php中查看订单按钮）时，价值应该是沙拉和三明治而不是汉堡和披萨。

我希望你理解我的解释，我希望你的帮助，我真的需要马上解决这个问题。我已经把这个问题累了好几天了。非常感谢你的帮助。非常感谢！

This is my error

This is what I get when clicking a button inside the ordermodal.php

这是我的order.php代码。

<button type="button"

Answer 1

更改此行

document.getElementsByName（“ORDER_ID”）[0] .setAttribute（“value”，order_id）;

要

document.getElementsByName（“ORDER_ID”）[1] .setAttribute（“value”，order_id）;

如何从其他页面获取值
