File upload field error

Hi!

Every time I use an upload field it needs to be filled in. Even though I don’t put it as required, the system shows an error as seen below:

I want to give the user the option to send a file or not. With this error I can only leave it as mandatory.

Does anyone know how to fix?

@willvin do you know how to solve this?

you will have to manually edit the file giving the error yourself.
Replace

$modeldata['image'] = $fileInfo['filepath'];

with

if($fileInfo['filepath']) {
    $modeldata['image'] = $fileInfo['filepath'];
}

or

if(isset($fileInfo['filepath'])) {
    $modeldata['image'] = $fileInfo['filepath'];
}
