Laravel：withInput - htmlentities（）期望參數1是字符串，數組給定

Question

我遇到了laravel上的「withInput」問題。我試圖與前書面提交的輸入控制器的驗證有誤時做出的回報，使用如下線路：

$validator = Validator::make(Input::all(), [ 
    "rsocial" => "required", 
    "cidade_id" => "required", 
    "status_id" => "required", 
]); 

if ($validator->fails()) 
    return redirect()->route("clientesCadastrar")->withErrors($validator)->withInput(); 

但我在與結果的問題，並出現以下錯誤：

ErrorException in helpers.php line 531: htmlentities() expects parameter 1 to be string, array given

我該怎麼辦？

Answer 1

這通常是因爲陣列在刀片模板中作爲字符串使用而發生的。你能發佈完整的堆棧跟蹤嗎？

Answer 2

The back() function generates a redirect response to the user's previous location.

Back-Helper Function - Laravel Docs

這可能會幫助：

if ($validator->fails()) { 
    return back() 
     ->withInput() 
     ->withErrors($validator); 
}
