yii2 form file widget give validation error on every update

model code :

[['thumbnail_image'], 'required', 'message' => 'Please upload an image.'],

view:

$form->field($model, 'thumbnail_image')->fileInput(['accept' => 'image/*', 'onchange' => 'readURL(this)'])->label('Thumbnail Image', ['class' => 'control-label thumbnail-image-class'])

File input forces uploading file with every update. even thumb image value available but it gives error to thumb image is required.

[['thumbnail_image'], 'required', 'message' => 'Please upload an image.', 'when' => function($model) {
        return  ($model->thumbnail_image) ? 0:1;
        }, 'whenClient' => "function (attribute, value) {
            if ($('#thumb_id').val() == '') {
               return 1;
            } else {
               return 0;
            }
        }"],

I fixed issue with conditional validation of YII2. we have to check on update record that thumb image exist or not. 0 for no required

[['thumbnail_image'], 'required', 'message' => 'Please upload an image.', 'when' => function($model) {
            return  ($model->thumbnail_image) ? 0:1;
            }, 'whenClient' => "function (attribute, value) {
                if ($('#thumb_id').val() == '') {
                   return 1;
                } else {
                   return 0;
                }
            }"],

Use ImageValidator to validate images and uploadRequired property

[['thumbnail_image'], 'file', 'uploadRequired' => true', 'skipOnEmpty' => false, 'extensions' => 'png, jpg'],

And read carefully http://www.yiiframework.com/doc-2.0/guide-input-file-upload.html to properly implement file uploading
