Class yii\web\MultipartFormDataParser

Inheritanceyii\web\MultipartFormDataParser » yii\base\BaseObject
Implementsyii\base\Configurable, yii\web\RequestParserInterface
Available since version2.0.10
Source Code https://github.com/yiisoft/yii2/blob/master/framework/web/MultipartFormDataParser.php

MultipartFormDataParser parses content encoded as 'multipart/form-data'.

This parser provides the fallback for the 'multipart/form-data' processing on non POST requests, for example: the one with 'PUT' request method.

In order to enable this parser you should configure yii\web\Request::$parsers in the following way:

return [
    'components' => [
        'request' => [
            'parsers' => [
                'multipart/form-data' => 'yii\web\MultipartFormDataParser'
            ],
        ],
        // ...
    ],
    // ...
];

Method parse() of this parser automatically populates $_FILES with the files parsed from raw body.

Note: since this is a request parser, it will initialize $_FILES values on yii\web\Request::getBodyParams(). Until this method is invoked, $_FILES array will remain empty even if there are submitted files in the request body. Make sure you have requested body params before any attempt to get uploaded file in case you are using this parser.

Usage example:

use yii\web\UploadedFile;

$restRequestData = Yii::$app->request->getBodyParams();
$uploadedFile = UploadedFile::getInstancesByName('photo');

$model = new Item();
$model->populate($restRequestData);
copy($uploadedFile->tempName, '/path/to/file/storage/photo.jpg');

Note: although this parser fully emulates regular structure of the $_FILES, related temporary files, which are available via tmp_name key, will not be recognized by PHP as uploaded ones. Thus functions like is_uploaded_file() and move_uploaded_file() will fail on them.

Property Details

$force public property (available since version 2.0.13)

Whether to parse raw body even for 'POST' request and $_FILES already populated. By default this option is disabled saving performance for 'POST' requests, which are already processed by PHP automatically. > Note: if this option is enabled, value of $_FILES will be reset on each parse.

$uploadFileMaxCount public property

Maximum upload files count.

$uploadFileMaxSize public property
