Hi,
I am trying to create a Form (based on a Model and Controller) with three optional file upload fields. I made them of the type file in the Model itself:
array('cover_image', 'file', 'types'=>'jpg, gif, png'),
...
Then I checked wether a file was submitted in the Create/Update action of the controller:
$cover_image =CUploadedFile::getInstance($model,'cover_image');
if ((is_object($cover_image) && get_class($cover_image)==='CUploadedFile')) {
$model->cover_image = $cover_image;
}
...
if($model->save()) {
if(is_object($cover_image)) {
$model->cover_image->saveAs(Yii::app()->basePath . '/../editions/' . $model->name . "_" . $model->cover_image);
}
...
$this->redirect(array('view','id'=>$model->id));
}
The field is not set as required. Nevertheless, the form validation gives me always a "Cover image cannot be blank" error when submitting. This should not happen. If the file was not set, it should not be saved/updated anything.
How do I do this?
