'sourceUrl.regex:'.$regex=>'mistake',

Answer 1

您需要返回失败的验证消息，如下所示：

$validation = Validator::make($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);

Answer 2

'sourceUrl.regex:'.$regex=>'mistake',不是有效的PHP代码。

它应该类似于：'sourceUrl.regex' => 'regex mistake'

这会重定向回错误消息regex mistake。

在您的视图中，您可以使用@error('sourceUrl') {{ $message }}@enderror打印邮件。
