每当用户访问mywebsite.com/profile时,我希望表单预先填充他们在注册/注册流程中输入的值.我能够在这里用我的表格做到这一点
<h1><b>Your Profile</b></h1>
<form method="POST" action="/profile/update">
<div class="form-group hidden">
<input type="hidden" name="_token" value="{{ csrf_token() }}">
<input type="hidden" name="_method" value="PATCH">
</div>
<div class="form-group {{ $errors->has('name') ? ' has-error' : '' }}">
<label for="email" class="control-label"><b>Name:</b></label>
<input type="text" name="name" placeholder="Please enter your email here" class="form-control" value="{{ $user->name }}"/>
<?php if ($errors->has('name')) :?>
<span class="help-block">
<strong>{{$errors->first('name')}}</strong>
</span>
<?php endif;?>
</div>
<div class="form-group {{ $errors->has('email') ? ' has-error' : '' }}">
<label for="email" class="control-label"><b>Email:</b></label>
<input type="text" name="email" placeholder="Please enter your email here" class="form-control" value="{{ $user->email }}"/>
<?php if ($errors->has('email')) :?>
<span class="help-block">
<strong>{{$errors->first('email')}}</strong>
</span>
<?php endif;?>
</div>
<div class="form-group">
<button type="submit" class="btn btn-default"> Submit </button>
</div>
</form>
但是,如果用户只是点击提交按钮而不更改任何字段,我现在遇到问题,laravel的内置验证检查并给我一个错误消息已经采取了名称.这是真的.所以我不知道如何处理这个问题,但这里是我的控制器
<?php
namespace App\Http\Controllers;
use Auth;
use App\User;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
class ProfileController extends Controller
{
/**
* Update user profile & make backend push to DB
*
**/
public function index() {
/**
* fetching the user model
**/
$user = Auth::user();
//var_dump($user);
/**
* Passing the user data to profile view
*/
return view('profile', compact('user'));
}
public function update(Request $request) {
/**
* Validate request/input
**/
$this->validate($request, [
'name' => 'required|max:255|unique:users',
'email' => 'required|email|max:255|unique:users',
]);
/**
* storing the input fields name & email in variable $input
* type array
**/
$input = $request->only('name','email');
/**
* fetching the user model
*/
$user = Auth::user();
/**
* Accessing the update method and passing in $input array of data
**/
$user->update($input);
/**
* after everything is done return them pack to /profile/ uri
**/
return back();
}
}
这是我的路线文件.
// only authenticated users
Route::group( ['middleware' => 'auth'], function() {
Route::get('/home', 'HomeController@index');
// practicing using forms for sending data to the DB & populating form fields with DB data
Route::get('profile', 'ProfileController@index');
Route::patch('profile/{id}', 'ProfileController@update');
});
解决方法:
问题是由于唯一的验证规则.您可以通过指定唯一验证规则来排除当前用户ID.你的代码就是这样的
public function update(Request $request) {
/**
* fetching the user model
*/
$user = Auth::user();
/**
* Validate request/input
**/
$this->validate($request, [
'name' => 'required|max:255|unique:users,name,'.$user->id,
'email' => 'required|email|max:255|unique:users,email,'.$user->id,
]);
/**
* storing the input fields name & email in variable $input
* type array
**/
$input = $request->only('name','email');
/**
* Accessing the update method and passing in $input array of data
**/
$user->update($input);
/**
* after everything is done return them pack to /profile/ uri
**/
return back();
}
