Question

目前，我的代码打印出mysql表的内容，它包含一个删除按钮。如何让这个按钮从mysql表中删除相应的条目？另外，我如何才能使表格只显示某些数据的条目（例如，不显示今天之前的条目）？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>
</body>
</html>

Answer 1

你可以试试这个..

<a href='delete.php?id=".$student['id']."'>Delete</a>

简单地将其放在td tag中，并在delete.php中写入删除查询。

Answer 2

试试这个

<form action="" method="post">
<?php
if(isset($_REQUEST['delete']) and is_numeric($_REQUEST['delete']))
{
        $sql = "DELETE FROM bookings WHERE id=3";
}
while ($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>".$student['phone']."</td>";
        echo "<td><a href='delete.php?delete=".$student['id']."'>Delete</a> </td>";
        echo "</tr>";
}
?>
</form>

用于从MySQL表中删除特定条目的按钮代码（使用php）？
