php - Failed to set unsafe attribute
Get the solution ↓↓↓
Solution:
CFileValidator is by default unsafe, from the docs:
safe property (available since v1.1.12) public boolean $safe;
whether attributes listed with this validator should be considered safe for massive assignment. For this validator it defaults to false.
So set safe attribute to true
array('logo', 'file', 'types'=>'jpg, jpeg, gif, png','safe'=>true, 'maxSize'=>100*1024, 'allowEmpty'=>true, 'tooLarge'=>'{attribute} is too large to be uploaded. Maximum size is 100kB.'),
