Is your issue that you want a custom error message, or that you don't know how to display the error message if your validation fails? — Peppermintology, Aug 06 '20 at 07:47

I am assuming you're working with an API as you mentioned Postman, if not please clarify in your question. — Peppermintology, Aug 06 '20 at 08:08

'sourceUrl.regex:'.$regex=>'mistake', is not valid PHP code.

It should be something like: 'sourceUrl.regex' => 'regex mistake'

This redirects back with the error message regex mistake.

In your view you can print the message with @error('sourceUrl') {{ $message }}@enderror.

You need to return your failed validation messages, something like the following:

$validation = Validator::make($request->all(), [
    'title' => 'required|min:10|max:250', //work
    'subTitle' =>'sometimes|present|nullable|min:10|max:250', //work
    'message' => 'required|min:10',//work
    'recommendPic' => 'present|nullable', //work
    'pic' => 'required|sometimes', //file - check upload file,image need fix
    'sourceUrl' =>'required|regex:'.$regex,
]);

// if validation fails
if ($validation->fails()) {
  return response()->json([
    'status' => 'failure',
    'errors' => $validation->errors()
  ], 400);
}

// validation passes
return response()->json(['status' => 'success'], 200);
