$v = \Validator::make($request->all(), [
    'input_image' => 'max:1024|mimes:jpeg',
],
[
    'max' => '大小請小於1MB(1024KB)',
    'mimes' => '請使用JPG檔'
]);
if ($v->fails()) {
		return redirect()->back()->withInput($request->input())->withErrors($v->errors());
}
ps.放$v->errors()跟$v都可以,withInput()裡面不一定要放東西

等同於

$this->validate($request, [
    'input_image' => 'max:1024|mimes:jpeg',
],
[
    'max' => '大小請小於1MB(1024KB)',
    'mimes' => '請使用JPG檔'
]);

因為在app/Http/Controllers/Controller.php
可以看到use ........ , ValidatesRequests;
原始碼在vendor/laravel/framework/src/Illuminate/Foundation/Validation/ValidatesRequests.php
