php-使用复选框删除多个MySQL项目
作者:互联网
我有一个允许用户选择几个项目的表格:
<table>
<form name="delete" action="proceed.php" method="post">
<?php
require_once 'cnn.php';
$viewPhoto = mysqli_query($cnn, "SELECT * FROM competition WHERE round = 2 ORDER BY id Desc");
while($row = mysqli_fetch_array($viewPhoto)) { ?>
<tr><td><input type="checkbox" name="check[]" value="<?php echo $row['id']; ?>"></td>
<td><?php echo $row['id']; ?></td>
<td><img title="" src="<?php echo $row['url']; ?>" width="178" height="150" /></td></tr>
<?php } ?>
<input type="submit" name="delete" value="Delete items">
</form>
</table>
然后,procedure.php包括:
<?php
require_once 'cnn.php';
$sql = mysqli_query($cnn, "SELECT * FROM competition");
if(isset($_POST['delete'])){
foreach ($_POST["check"] as $id){
$sql = "DELETE FROM soutez WHERE id='$id'";
}
echo "Items deleted";
}
?>
但是,这些项目不会从数据库中删除.错误可能在哪里?
解决方法:
您缺少循环执行删除记录的实际查询
<?php
require_once 'cnn.php';
$sql = mysqli_query($cnn, "SELECT * FROM soutez");
if(isset($_POST['delete'])){
foreach ($_POST["check"] as $id){
$sql = "DELETE FROM soutez WHERE id='$id'";
//Here you are missing below statement
mysqli_query($cnn, $sql);
}
echo "Items deleted";
}
?>
