Hi everyone. Anything wrong with this code?
It supposed to ensure that the uploaded file is not greater than ‘3MB’, but the error message appears even when the uploaded file is ‘2MB’.
I also tried COMPARE_GREATER… but it does the same.
Make sure your <form> tag is setup correctly to have enctype="multipart/form-data" set.
This can be done via doing
$this->Form->create($entity, ['type' => 'file']);
Then your submited file is of type \Psr\Http\Message\UploadedFileInterface and not just a string.
See Form - 4.x
Then your validation rule should be working fine.
I think the code has met those two. It even uploads some pictures as expected. But fails to deal with others.
The problem was the limitation of upload_max_filesize in php.ini to 2M.
Problem solved.
