Question

其实这是主要问题。它没有获得可以在这里用作条件的“$ radio [$ i]”语句的值。所以有人请告诉我在那里写的东西而不是“$ radio [$ i]”，因为输出会来。

<?php
if(isset($_POST['delete']))
{
    for($i=0;$i<$count;$i++)
    {
        $del_id = $radio[$i];
        $sql = "DELETE FROM reigster WHERE id='".mysql_real_escape_string($del_id)."'";
        $result = mysql_query($sql);
    }
    if($result)
    {
        echo "<meta http-equiv=\"refresh\" content=\"0;URL=delete_multiple.php\">";
    }
}
mysql_close();
?>

Answer 1

查看上一个问题之后问题出现在这段代码

中

for($i=0;$i<$count;$i++)
 {
 $del_id = $radio[$i];
 $sql = "DELETE FROM reigster WHERE id='".mysql_real_escape_string($del_id)."'";
 $result = mysql_query($sql);
 }

将上面的代码替换为

     $count=count($_POST['radio']); 
     for($i=0;$i<$count;$i++)
     {
       $del_id = $_POST['radio'][$i];
       $sql = "DELETE FROM reigster WHERE id='".mysql_real_escape_string($del_id)."'";
       $result = mysql_query($sql);
     }

Answer 2

 foreach($_POST['radio'] as $del_id)
 {
   $sql = "DELETE FROM reigster WHERE id='".mysql_real_escape_string($del_id)."'";
   $result = mysql_query($sql);
 }

Answer 3

试试这个

if(isset($_POST['delete']))
{
    for($i=0;$i<$count;$i++)
    {
        $del_id = $radio['checked'];
        $sql = "DELETE FROM reigster WHERE id='".mysql_real_escape_string($del_id)."'";
        $result = mysql_query($sql);
    }
    if($result)
    {
        echo "<meta http-equiv=\"refresh\" content=\"0;URL=delete_multiple.
