按钮的代码，用于从MySQL表中删除特定条目（使用php）？
[英]Code for button to delete specific entries from a MySQL table (using php)?
问题描述
Currently, my code prints out the contents of a mysql table and it contains a delete button. 
目前，我的代码打印出mysql表的内容，并且包含一个删除按钮。 How can I get this button to delete the corresponding entry from the mysql table? 如何获得此按钮以从mysql表中删除相应的条目？ Also, how can I make it so that the table only displays entries of a certain data (eg do not display entries from before the today's date)? 另外，如何使表格仅显示某些数据的条目（例如，不显示今天日期之前的条目）？ Any help would be greatly appreciated. 任何帮助将不胜感激。
<?php
include('php/connect.php');
mysql_connect ($host,$user,$password);
mysql_select_db('booking');
$sql="SELECT *FROM bookings";
$records = mysql_query($sql);
?>
<html>
<head>
<title>Records</title>
</head>
<body>
<table width = "600" border = "1" cellpadding = "1" cellspacing = "1">
<tr>
<th>ID</th>
<th>Date</th>
<th>Start</th>
<th>Name</th>
<th>E-mail</th>
<th>Phone</th>
<th>Delete</th>
</tr>
<form action="" method="post">
<?php
if(isset($_POST['delete']) and is_numeric($_POST['delete']))
{
$sql = "";
}
while ($student = mysql_fetch_assoc ($records)){
echo "<tr>";
echo "<td>".$student['id']."</td>";
echo "<td>".$student['date']."</td>";
echo "<td>".$student['start']."</td>";
echo "<td>".$student['name']."</td>";
echo "<td>".$student['email']."</td>";
echo "<td>".$student['phone']."</td>";
echo "<td> <input type=submit name=delete id=".$student['id']." value=delete </td>";
echo "</tr>";
}
?>
</form>
</table>

You can try this.. 你可以试试看
<a href='delete.php?id=".$student['id']."'>Delete</a>
Simple put this in td tag and write query for delete in delete.php . delete.php将其放在td tag然后在delete.php编写删除查询delete.php 。
