Codeigniter 遇到PHP错误严重性：尝试获取非对象文件名：

查看发生错误的零件

<select name="standard" class="form-control">

控制器部件

public function add_standard($action='',$id='') {

      $this->load_syles();

         $course = array();
     if ($action == 'edit' and $id != '' and is_numeric($id)) {
    $course = $this->news_model->getStandard($id);
     }

    $this->data['course'] = $course ;

    $this->data['title'] = 'Add Standard';
    $this->data['page_header'] = "Add Standard";
    $this->data['page_header_desc'] = "Add Standard";
    $details=$this->news_model->viewAllStandard();
    $this->data['details']=$details;
    $this->data['count']=count($details);
    $this->data['is_edit']=$action;

你写的

$course = array()

然后用

$course->medium

好像它是一个物体

您应该在您编写的视图（html）中使用

$course['medium']

$course = array()

然后用

$course->medium

好像它是一个物体

您应该在视图（html）中使用

$course['medium']

更改您的模型

public static function getStandard($id)
{
    $this->db->select("*");
    $this->db->from('standard');
    $this->db->where('id',$id);
    $res=$this->db->get();
    return $res->row_array();
}

将

$course->medium

更改为

$course['medium']

<select name="standard" class="form-control">
<option <?php if($course['medium'] =='E'){ echo "selected";} ?>  value="English" >English</option>
<option  <?php  if($course$course['medium'] =='M'){ echo "selected";} ?>  value="Malayalam">Malayalam</option>

value=“Malayalam”>Malayalam

像这样更改您的型号

public static function getStandard($id)
{
    $this->db->select("*");
    $this->db->from('standard');
    $this->db->where('id',$id);
    $res=$this->db->get();
    return $res->row_array();
}

将

$course->medium

更改为

$course['medium']

<select name="standard" class="form-control">
<option <?php if($course['medium'] =='E'){ echo "selected";} ?>  value="English" >English</option>
<option  <?php  if($course$course['medium'] =='M'){ echo "selected";} ?>  value="Malayalam">Malayalam</option>

value=“Malayalam”>Malayalam
