[英]Code for button to delete specific entries from a MySQL table (using php)?
目前，我的代碼打印出mysql表的內容，並且包含一個刪除按鈕。 如何獲得此按鈕以從mysql表中刪除相應的條目？ 另外，如何使表格僅顯示某些數據的條目（例如，不顯示今天日期之前的條目）？ 任何幫助將不勝感激。
<?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>
你可以試試看
<a href='delete.php?id=".$student['id']."'>Delete</a>
delete.php將其放在td tag然后在delete.php編寫刪除查詢delete.php 。
嘗試這個
<form action="" method="post">
<?php
if(isset($_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>
