yii2 failed to upload file

Let’s take a look at the code first:

First look at the View part: 

<form action="<?= Url::to([&#39;default/datafile&#39;]) ?>" method="post" enctype="multipart/form-data">
    <label for="file">Filename:</label>
    <input type="file" name="myFile" id="file" />
    <br />
    <input type="submit" name="submit" value="Submit" />
</form>

The above action is built using the YII helper class The url that can be recognized internally is actionDatafile()

in DeaufaultController.php (recommended tutorial: yii framework)

 public function actionDatafile(){
        if(empty($_FILES)){
            $status = 1;
            $info = &#39;沒有文件上傳&#39;;
        }
        if($_FILES[&#39;myFile&#39;][&#39;error&#39;] === 0 || $_FILES[&#39;myFile&#39;][&#39;error&#39;] === &#39;0&#39; ){
            //文件上傳成功
            $tmp = pathinfo($_FILES[&#39;myFile&#39;][&#39;name&#39;]);
            $new_fname = $tmp[&#39;filename&#39;].&#39;_&#39;.rand(1000000,9999999).&#39;.&#39;.$tmp[&#39;extension&#39;];
            echo $new_fname;
            if(!move_uploaded_file($_FILES[&#39;myFile&#39;][&#39;tmp_name&#39;], &#39;../runtime/file/&#39;.$new_fname)){
                $status = 1;
                $info = &#39;上傳（移動）失敗&#39;;
            }else{
                $status = 0;
                $info = &#39;上傳成功&#39;;
            }
        } else {
            //文件上傳失敗
            $info = &#39;文件上傳失敗&#39;;
            switch($_FILES[&#39;myFile&#39;][&#39;error&#39;]){
                case 1:
                    $info = &#39;上傳文件超過php.ini中upload_max_filesize配置參數(shù)&#39;;
                    break;
                case 2:
                    $info = &#39;上傳文件超過表單MAX_FILE_SIZE選項指定的值&#39;;
                    break;
                case 3:
                    $info = &#39;文件只有部份被上傳&#39;;
                    break;
                case 4:
                    $info = &#39;沒有文件被上傳&#39;;
                    break;
                case 5:
                    $info = &#39;上傳文件大小為0&#39;;
                    break;
            }
            $status = 1;
        }
        return $info;
    }

found after execution

yii2 failed to upload file

Solution:

1. Check the configuration (php.ini)

file_uploads, upload_max_filesize, post_max_size, and upload_tmp_dir have been set.

2. Check the parameters

Found crsf in the parameters. This parameter is included in the yii framework verification. When it comes to verification, it is similar to the error message. Add the cancellation verification code, as follows: 

public function beforeAction($action)
    {
        if ($action->id == &#39;datafile&#39;) {
            $this->enableCsrfValidation = false;
        }
 
        return parent::beforeAction($action);
    }

How do I render a view from a controller? How do I render a view from a controller? Jul 07, 2025 am 12:09 AM

In the MVC framework, the mechanism for the controller to render views is based on the naming convention and allows explicit overwriting. If redirection is not explicitly indicated, the controller will automatically find a view file with the same name as the action for rendering. 1. Make sure that the view file exists and is named correctly. For example, the view path corresponding to the action show of the controller PostsController should be views/posts/show.html.erb or Views/Posts/Show.cshtml; 2. Use explicit rendering to specify different templates, such as render'custom_template' in Rails and view('posts.custom_template') in Laravel

How do I save data to the database using Yii models? How do I save data to the database using Yii models? Jul 05, 2025 am 12:36 AM

When saving data to the database in the Yii framework, it is mainly implemented through the ActiveRecord model. 1. Creating a new record requires instantiation of the model, loading the data and verifying it before saving; 2. Updating the record requires querying the existing data before assignment; 3. When using the load() method for batch assignment, security attributes must be marked in rules(); 4. When saving associated data, transactions should be used to ensure consistency. The specific steps include: instantiating the model and filling the data with load(), calling validate() verification, and finally performing save() persistence; when updating, first obtaining records and then assigning values; when sensitive fields are involved, massassignment should be restricted; when saving the associated model, beginTran should be combined

How do I create custom actions in a Yii controller? How do I create custom actions in a Yii controller? Jul 12, 2025 am 12:35 AM

The method of creating custom operations in Yii is to define a common method starting with an action in the controller, optionally accept parameters; then process data, render views, or return JSON as needed; and finally ensure security through access control. The specific steps include: 1. Create a method prefixed with action; 2. Set the method to public; 3. Can receive URL parameters; 4. Process data such as querying the model, processing POST requests, redirecting, etc.; 5. Use AccessControl or manually checking permissions to restrict access. For example, actionProfile($id) can be accessed via /site/profile?id=123 and renders the user profile page. The best practice is
