Question

我想根据用户登录禁用我的下拉列表。我将用户类型存储在会话中。

现在管理员创建用户。然后该用户可以登录并编辑他的详细信息。

我想只允许该用户编辑某些字段。

就像我不想让他编辑他的user_type一样。

现在，如果我从表单字段中删除它们，则会在mysql中截断数据时出现错误。如果我通过html禁用它会显示相同的错误。

请帮帮我

是控制器代码：

public function edit ($id = NULL)
{
    $user_type = $this->session->userdata('user_type');


    if($user_type =="admin")
        {

            if ($id) 
                {
                    $this->data['user'] = $this->user_m->get($id);
                    count($this->data['user']) || $this->data['errors'][] = 'User could not be found';



                    // Set up the form
                    $rules = $this->user_m->rules_admin;
                    $id || $rules['password']['rules'] .= '|required';
                    $this->form_validation->set_rules($rules);

                                // Process the form
                    if ($this->form_validation->run() == TRUE) 
                    {

                        $data = $this->user_m->array_from_post(array('emp_id','name','last_name','email','password','phone','gender','designation','user_type','blood_group','date_birth','status','address'));

                        if(!empty($data['password'])) 
                        {
                            $data['password'] = $this->user_m->hash($data['password']);
                        } else {
                            // We don't save an empty password
                            unset($data['password']);
                        }
                        $key=$this->user_m->save($data, $id);

                    }

                }

                        // Load the view
                        $this->data['subview'] = 'admin/users/edit';
                        $this->load->view('admin/_layout_main', $this->data);

        }

    elseif($user_type=="employee")
        {   



            if ($id)

                    //$data['password'] = $this->user_m->hash($data['password']);

                    if(!empty($data['password'])) 
                    {
                        $data['password'] = $this->user_m->hash($data['password']);

If ($user_type =="admin") {
  $select = '';
}
elseif($user_type=="employee"){
  $select = 'disabled';
}
// to prevent warning use this<?php isset($select) ? $select : ''; ?>
// Above is shortcode for if(isset($select)){echo $select;}else{echo '';}

<select <?php isset($select) ? $select : ''; ?> >
  <option value="volvo">Volvo</option>
  <option value="saab">Saab</option>
  <option value="mercedes">Mercedes</option>
  <option value="audi">Audi</option>
</select>

您可以对登录的用户类型进行检查。

If (admin) {
  // SHOW DROP DOWN
}
else {
  // SHOW JUST TEXT (SELECTED ONE FROM DROP DOWN)
  // HIDE THE DROP DOWN BOX USING CSS PROPERTY: `display:none`
}

如何根据用户登录启用禁用下拉列表？
