【问题描述】：

我的验证控制器：

public function store(Request $request)
{
   // dd($request->all());

    /////Validations////

    $this->Validate($request, [
        'name' => 'required|min:3|',
        'email' => 'required|unique:customers' ,
        'favorite' => 'required',
        'Password' => 'required|min:6',
        'Confirm_Password' => 'required|same:Password',
        ]);

    $user = new customer;
    $user ->name=input::get("name");
    $user ->email=input::get("email");
    $user ->country=input::get("country");
    $user ->gender=input::get("gender");
    $user ->favorite=implode(" , " , input::get("favorite"));

    if(input::hasfile("image")){
        $files = Input::file('image');
        $name = time()."_". $files->getClientOriginalName();
        $image = $files->move(public_path().'/image' , $name);
        $user->image=$name;
    }

    $user ->psw=input::get("psw");

    $user->save();
    return redirect("showall");
}

插入.blade.php

我要更改字段颜色的表单：

当我收到验证错误时，我想将输入字段的边框颜色更改为红色。我尽力了，但我不知道如何解决这个问题。

【解决方案1】：

先添加这段 CSS 代码：

.form-error {

  border: 2px solid #e74c3c;
}

而 HTML 代码是 ::

<input type="text" class="form-control{{($errors->first('name') ? " form-error" : "")}}" name="name" placeholder="Name">

如果您需要输入字段下方的错误消息，那么 ::

    <input class="form-control" required="required" name="name" type="text" id="name">
    {!! $errors->first('name', '<p class="help-block">:message</p>') !!}
