Hi Guys,

im trying to use image cropbox by bupy7. I want to use it to manage a mysql table (id, name, img_path) and try to copy the cropped image into another folder in backend/web/ then i want to insert that path to my db.

But when i want to create a new row in to the db i get this error message:


PHP Notice – yii\base\ErrorException
