Question

我想请一些帮助。

我发送了一个来自多选字段的GET请求，将所选值发送到我的进程页面（archive.php）

<form id="form1" class="four columns" action="archive.php" method="get" name="form1">
<select id="select2" multiple="multiple" name="location[]">
<option value="103001000">value1</option>
<option value="103002000">value2</option>
<option value="103003000">value3</option>
<option value="103004000">value4</option>
</select>

我在我的网址上选择了这样的位置

location[]=103002000&location[]=103003000

并在archive.php中我试图从数据库中获取数据

if (( isset($_GET['location']) && !empty($_GET['location']) )) {
    die(var_dump($_GET['location'])); // the var_dump doesn't return an array at all
    $loc = implode(', ', $_GET['location']);

    $sql="SELECT  * FROM locations WHERE AreaID IN (". $loc.")";
}

但是我收到以下错误：错误：'where子句'中的未知列'Array'。

我该如何解决这个问题？

尝试如下，它可能很简单

 if (( isset($_GET['location']) && !empty($_GET['location']) )) {
        die(var_dump($_GET['location'])); // the var_dump doesn't return an array at all
        //$loc = implode(', ', $_GET['location']);
        $_GET['location'] = array('first'=>'loc1','second'=>'loc2','third'=>'loc3');
        $loc = implode('","', $_GET['location']);
        $loc ='"'.$loc.'"';

        $sql='SELECT  * FROM locations WHERE AreaID IN ('.$loc.')';
        echo $sql;
    }

结果查询

SELECT * FROM locations WHERE AreaID IN ("loc1","loc2","loc3")

无法通过$ _GET请求从多个select中获取值
