Question

这是我的网址

db_control.php?workname=Test+message&worktype=1&workscore=10&multi%5B%5D=4&multi%5B%5D=24&frmsubmit=

这是我的PHP代码

if(isset($_REQUEST['frmsubmit']))
{
    echo $_REQUEST['workname']; echo '<br>';
    echo $_REQUEST['workscore'];echo '<br>';
    foreach($_REQUEST['multi'] as $mlti => $n)
    {
        echo $n;echo '<br>';
    }
}

我收到了这个答案

测试消息 10

$_REQUEST['multi'] returns empty why..?

这些都来自表格帖子（表格方法是获得）

我做错了什么？请以正确的方式引导我。提前谢谢。

执行此操作的正确方法是以下列方式将多个值放在一个参数multi中。

使用：

http://example.com/workname=Test+message&worktype=1&workscore=10&multi=4,24&frmsubmit=

而不是：

http://example.com/workname=Testmessage&worktype=1&workscore=10&multi[]=4&multi[]=24&frmsubmit=

使用explode像这样访问“multi”的值：

if(isset($_REQUEST['frmsubmit']))
{
    echo $_REQUEST['workname']; echo '<br>';
    echo $_REQUEST['workscore'];echo '<br>';
    $multiParam = explode(",",$_REQUEST['multi']);
    foreach($multiParam as $mlti => $n)
    {
        echo $n;echo '<br>';
    }
}
