Php 将下拉列表转到另一页

在加载add operator的表单之前，我必须使用php文件addoperator.php调用web服务，该文件返回了一个json，其中包含Organization、location、building的值，我已将该json值转换为下拉列表，现在这些下拉列表必须位于Organization字段下，“添加”操作符窗体中的位置和建筑

她是addoperator.php的代码

<?php
session_start();
$url='webservice url';
$ch=curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($useridofuser));
    curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json"));
    $response=  curl_exec($ch);
    echo('\n'."Server response : \n \n".$response);
    curl_close($ch);
    //parsing the json response from server
    $jsonde="$response";
$org = array();
$loc = array();
$bui = array();
$items = json_decode($response);
foreach( $items as $each ){
$loc[]=$each->location[0]->name;
$bui[]=$each->location[0]->building[0];
$org[]=$each->name;
}
?>
<select name="category_id">
<option value=""></option>
<?php
foreach($org as $key=>$val)
{?>
<option value="<?php echo $key; ?>"><?php echo $val; ?></option>
<?php
}
?>
</select>
<select name="category_id">
<option value=""></option>
<?php
foreach($loc as $key=>$val)
{?>
<option value="<?php echo $key; ?>"><?php echo $val; ?></option>
<?php
}
?>
</select>
<select name="category_id">
<option value=""></option>
<?php
foreach($bui as $key=>$val)
{?>
 <option value="<?php echo $key; ?>"><?php echo $val; ?></option>
 <?php
}
?>
</select>

您将下拉列表从addoperator.php添加到addoperatorui.php是什么意思？我想将我在operator.php中创建的下拉列表替换为我表单中的字段组织我可以用session来完成吗？您是否尝试从中选择的内容填充？不，我想以任何方式将整个选项添加到另一个页面将web服务页面集成到表单页面的解决方案
