Class yii\web\MultipartFormDataParser
Inheritance | yii\web\MultipartFormDataParser » yii\base\BaseObject |
---|---|
Implements | yii\base\Configurable, yii\web\RequestParserInterface |
Available since version | 2.0.10 |
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 viatmp_name
key, will not be recognized by PHP as uploaded ones. Thus functions likeis_uploaded_file()
andmove_uploaded_file()
will fail on them.

Property Details
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.
Maximum upload files count.
Upload file max size in bytes.
Method Details
Defined in: yii\base\BaseObject::__call()
Calls the named method which is not a class method.
Do not call this method directly as it is a PHP magic method that will be implicitly called when an unknown method is being invoked.
public mixed __call ( $name, $params ) | ||
$name | string |
The method name |
$params | array |
Method parameters |
return | mixed |
The method return value |
---|---|---|
throws | yii\base\UnknownMethodException |
when calling unknown method |
public function __call($name, $params)
{
throw new UnknownMethodException('Calling unknown method: ' . get_class($this) . "::$name()");
}
Defined in: yii\base\BaseObject::__construct()
Constructor.
The default implementation does two things:
- Initializes the object with the given configuration
$config
. - Call init().
If this method is overridden in a child class, it is recommended that
- the last parameter of the constructor is a configuration array, like
$config
here. - call the parent implementation at the end of the constructor.
public void __construct ( $config = [] ) | ||
$config | array |
Name-value pairs that will be used to initialize the object properties |
public function __construct($config = [])
{
if (!empty($config)) {
Yii::configure($this, $config);
}
$this->init();
}
Defined in: yii\base\BaseObject::__get()
Returns the value of an object property.
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing $value = $object->property;
.
See also __set().
public mixed __get ( $name ) | ||
$name | string |
The property name |
return | mixed |
The property value |
---|---|---|
throws | yii\base\UnknownPropertyException |
if the property is not defined |
throws | yii\base\InvalidCallException |
if the property is write-only |
public function __get($name)
{
$getter = 'get' . $name;
if (method_exists($this, $getter)) {
return $this->$getter();
} elseif (method_exists($this, 'set' . $name)) {
throw new InvalidCallException('Getting write-only property: ' . get_class($this) . '::' . $name);
}
throw new UnknownPropertyException('Getting unknown property: ' . get_class($this) . '::' . $name);
}
Defined in: yii\base\BaseObject::__isset()
Checks if a property is set, i.e. defined and not null.
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing isset($object->property)
.
Note that if the property is not defined, false will be returned.
public boolean __isset ( $name ) | ||
$name | string |
The property name or the event name |
return | boolean |
Whether the named property is set (not null). |
---|
public function __isset($name)
{
$getter = 'get' . $name;
if (method_exists($this, $getter)) {
return $this->$getter() !== null;
}
return false;
}
Defined in: yii\base\BaseObject::__set()
Sets value of an object property.
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing $object->property = $value;
.
See also __get().
public void __set ( $name, $value ) | ||
$name | string |
The property name or the event name |
$value | mixed |

} else {
throw new UnknownPropertyException('Setting unknown property: ' . get_class($this) . '::' . $name);
}
}
Defined in: yii\base\BaseObject::__unset()
Sets an object property to null.
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing unset($object->property)
.
Note that if the property is not defined, this method will do nothing. If the property is read-only, it will throw an exception.
public void __unset ( $name ) | ||
$name | string |
The property name |
throws | yii\base\InvalidCallException |
if the property is read only. |

is true);
