getInstance not working File Update in REST API yii2

[jackhad]

Hi Im using REST API in yii 2 \yii\web\UploadedFile::getInstance is not getting file in my function.for debugging purpose I tried with $_FILES[‘asset’] its printing with values.but not getting file instance using \yii\web\UploadedFile::getInstance

$updateFile = $_FILES['asset']; //Printing values

$model->asset = \yii\web\UploadedFile::getInstance($model, 'asset'); //Not printing,its empty

What is the issues,I couldn’t validate If i process the file with $_FILES.Any help would be grateful!! Thanks in Advance

Is your form in the following manner? And the input field has a name attribute?

[html]<form id="model-form" name="model-form" method="post" role="form" ng-submit="submitForm()" role="form" enctype="multipart/form-data">

<input type="file" id="model_asset" name="Model[asset]" ng-model="Model.asset" required/>


<button type="submit" class="btn" title="Submit">Submit</button>

</form>[/html]

If not please add it and check?

You should use

\yii\web\UploadedFile::getInstanceByName('asset'); instead of getInstance().
