</form>

controller file

public function uploadMemberReports( Request $request ){
    # Validation  Rules
    $rules = [
        'reportdate'=>'required',
        'reportfile' => 'required|mimes:pdf',
    ];
    $messages = [
        'reportdate.required' =>'Date is required.',
        'reportfile.required' => 'File is required.',
        'reportfile.mimes' => 'Only PDF files are allowed.',
    ];

    $validator = Validator::make( $request->all(), $rules, $messages);

    if ( $validator->fails() ) {
        # if validations fails redirect back with errors
        return redirect()->back()->withErrors($validator)->withInput();
    } else {
        # next action
    }
}

When I try with valid PDF file it returning with error like following

The reportfile failed to upload.

Edit: The request array response

Array
(
    [_token] => yaX0ohRjl6tR298Zd9WeSLcgxcoVQ9nPx3K5gO4S
    [reportdate] => 2021-01-12
    [manager_id] => 2
    [member_id] => 4
    [reportfile] => IlluminateHttpUploadedFile Object
        (
            [test:SymfonyComponentHttpFoundationFileUploadedFile:private] => 
            [originalName:SymfonyComponentHttpFoundationFileUploadedFile:private] => labreports_12.pdf
            [mimeType:SymfonyComponentHttpFoundationFileUploadedFile:private] => application/octet-stream
            [error:SymfonyComponentHttpFoundationFileUploadedFile:private] => 1
            [hashName:protected] => 
            [pathName:SplFileInfo:private] => 
            [fileName:SplFileInfo:private] => 
        )

)

Answer 1

This can have several causes. But Frontend looks good at first glance. It could be a server problem. For example FileSize, MimeType. You can output the request variable in the first step to rule out the possibility that the PDF has not arrived.

Edit (see at your comments): 'required|mimes:application/pdf'
