使用 php 验证单选按钮 - Validating radio button using php

我目前正在为我的网页使用 CodeIgniter，如果locked_status被锁定，我正在尝试选择单选按钮，反之亦然。我有传递给视图的数据，我想使用这些数据来检查locked_status是否被锁定。用户可以更改locked_status，并且在提交表单时，数据会在提交表单时相应地更新。我正在尝试使用javascript，但我不知道如何检索数据并进行检查。或者有没有其他更好的方法可以做到这一点？

我的控制器加载视图并将数据传递到视图。

function userInformation($userName)
    {                           
        $this->load->model("agentDB_model");
        $data['results'] = $this->agentDB_model->getSelectedAgentDetails($userName);
        $this->load->view("viewAgentInfo_view", $data);     
    }

视图
