Php 需要使用DAO进行编辑和删除吗

php

Php 需要使用DAO进行编辑和删除吗,php,Php,我想知道是否有人能帮我解决这个问题。 我有一个带有删除、编辑、插入等方法的ReminderDAO类，还有一个带有构造函数、get和set的ReminderDAO类 然后我有一个视图提醒，它只是列出了所有的提醒。 我希望能够在此查看页面中添加编辑和删除 要在我的提醒道类中使用delete和edit函数，我需要通过该函数传递一个提醒对象，但我不太确定如何做到这一点 如果有人能帮助我，那将是一个很大的帮助，我是新的语言，所以我道歉，如果它不是伟大的代码 提前谢谢你 提醒道 class Reminder

我想知道是否有人能帮我解决这个问题。 我有一个带有删除、编辑、插入等方法的ReminderDAO类，还有一个带有构造函数、get和set的ReminderDAO类

然后我有一个视图提醒，它只是列出了所有的提醒。 我希望能够在此查看页面中添加编辑和删除

要在我的提醒道类中使用delete和edit函数，我需要通过该函数传递一个提醒对象，但我不太确定如何做到这一点

如果有人能帮助我，那将是一个很大的帮助，我是新的语言，所以我道歉，如果它不是伟大的代码

提前谢谢你

编辑提醒

标题：您可以将
提醒的
ID
发送到下一页，在那里您可以编辑/删除提醒

        echo "<b>Details:</b> " . $rem->getDetails() . "<br />";

        echo "[<a href='delete.php?id=" . $rem->getID() . "'>Delete</a>] ";

       echo "</p>";

    }



foreach（$rem形式的提醒）{
echo“Title:”.$rem->getTitle（）.“
”；
echo“Details:”.$rem->getDetails（）.“
”；
echo“Type:”..rem->getType（）“
”；
回声“[]”；
回声“[]”；
回声“
”；
}


在
edit.php
中，使用ID（例如
$\u get['ID']
）获取提醒对象，使用提醒DAO从数据库加载数据，并创建一个填充有提醒值的表单。在该表单中，您还应该放置提醒id，以便当他将表单提交到
保存更改
时，您可以识别已编辑的提醒。
保存更改后，您可以使用
标题
功能将他重定向回提醒列表


类似地，在
delete.php
中，您可以使用ID（例如
$\u GET['ID']
）删除提醒，然后将用户重定向到提醒列表。
非常感谢您的回答！但是，我不太确定edit.php中的含义。你能给我看一下我会用$_GET['id']在这行上写些什么吗？当然，如果你有时间的话。再次感谢您。您可以执行以下操作来检索通过GET发送的id为的提醒对象：
$rementer\u to\u edit=$rementerdao->getrementer（$\u GET['id']）
不幸的是，当我在下一页回显$_GET['id']时，当我在URL中单击“编辑”时，所有出现的都是“（）”并且没有传递id。URL是什么样子的？id是否有值？（例如，
localhost/my_project/edit.php？id=3
）哦。。我将代码更新为使用
“$rem->getID（）”
。让我知道它是否有效
