Question

我在laravel上遇到“withInput”问题。我正在尝试返回，当使用提交之前写入的输入在控制器验证上出错时，使用以下行：

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

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

但是我遇到了结果问题，出现以下错误：

helpers.php第531行中的ErrorException：htmlentities（）期望参数1为字符串，给定数组

我做什么？

Answer 1

这通常是因为数组在刀片模板中作为字符串使用。你能发布完整的堆栈跟踪吗？

Answer 2

back() 功能会生成对用户之前位置的重定向响应。

Back-Helper Function - Laravel Docs

这可能有所帮助：

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

Laravel：withInput - htmlentities（）期望参数1为字符串，给定
