我使用laravel 5.2创建了一个视图页面，在该页面中创建了一个表并从mysql数据库中获取数据。并为编辑和删除提供动态下拉按钮。当我点击删除它将从表中删除相应的行。我完成并正常工作。我想做编辑部分。当我单击编辑选项时，它将重定向到一个表单，我需要从相应的行获取所有细节到表单文本字段，我们可以编辑的东西，当我们点击保存按钮它将更新数据到mysql表。 在这里，我无法将相应行的详细信息提取到表单文本字段中。谁能帮助我做到这一点。 我的浏览页面＆＃34; userAdmin.blade.php＆＃34;是
@extends('app')
@section('content')

然后是route.php
Route::any('userAdmin', 'UserController@getIndex');
Route::any('user/add', 'UserController@getData');
Route::any('user/delete/{id}', 'UserController@delete');
Route::post('userAdmin', 'UserController@userInsert');
Route::any('user/add', function()

return view('user/add');
});
任何人都可以帮我这样做。回应很明显。

您的laravel代码并不遵循常规做法或使用laravel的正确方法。
请查看资源控制器 https://laravel.com/docs/5.2/controllers#restful-resource-controllers
也是雄辩的模特 https://laravel.com/docs/5.2/eloquent
现在让我们尝试解决您的问题，将这些问题添加到您的路线
//to show edit form and fetch passed user id info from db
Route::get('user/edit/{id}', 'UserController@edit');
//to get the edited info and save it to db
Route::get('user/update/{id}', 'UserController@update');
现在通过从项目目录运行此命令来创建一个名为user的模型：
php artisan make:model User
现在使用其他用法语句在控制器中添加这些
use App\User; /* User model */
use Illuminate\Database\Eloquent\ModelNotFoundException; /* find or fail error exception class */
现在将这些添加到您的控制器
// Show Edit page.
public function edit($user_id)
{
try{
//Find the user object from model if it exists
$user= User::findOrFail($user_id);
//Redirect to edit user form with the user info found above.
return view('add',['user'=>$user]);
}
catch(ModelNotFoundException $err){
//redirect to your error page
}
}
// Update user
public function update(Request $request, $user_id)
{
try{
//Find the user object from model if it exists
$user= User::findOrFail($user_id);
//Set user object attributes
//the $request index should match your form field ids!!!!!
//you can exclude any field you want.
$user->description = $request['description'];
$user->contactName = $request['contactName'];
$user->contactPhone = $request['contactPhone'];
$user->timeZone = $request['timeZone'];
//Save/update user.
$user->save();
//redirect to somewhere?
}
catch(ModelNotFoundException $err){
//Show error page
}
}
在编辑视图中，您可以通过
访问检索到的用户$user->description //$user->[attribute name]
由于你没有使用刀片，我相信你可以做到这一点，无论你在哪里（...）用旧的替换它（...）|| $用户＆GT; ... 除了选择标记
示例：
value="{{ old('contactName') || $user->contactName }}"
对于选择标签我会给你一个例子，你需要自己做其余的
<select class="form-control" value="{{ old('timeZone') || $user->timeZone}}" name="timeZone" >
<option value="0" {{ $user->timeZone == "0"? 'Selected':''}}>GMT+05:30</option>
<option value="Inactive" {{ $user->timeZone == "Inactive"? 'Selected':''}}>xyz</option>
</select>
