我已经阅读了一些教程和视频。我刚刚下载并安装了laravel。试图创建一个简单的注册表格。
welcome.blade.php
<form action="{{URL::to('/store')}}" method="post">
{{csrf_field()}}
<input type="text" name="clientFirstname" >
<input type="text" name="clientSurname" >
<input type="text" name="clientEmail">
<input type="hidden" name="token" value="">
<button type="submit" name="button">add</button>
</form>
web.php
Route::view('/', 'welcome');
Route::post('/store', "Controller@store");
Controller.php
class Controller extends BaseController {
public function store(Request $request) {
//print_r ($request->input());
//print_r ($request->input('clientFirstname'));
$result=DB::insert("INSERT INTO test('firstname', 'surname', 'email') VALUES(?, ?, ?)", $request->input('clientFirstname'), $request->input('clientSurname'), $request->input('clientEmail'));
echo $result;
}
}
.env
DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=testdb
DB_USERNAME=root
DB_PASSWORD=
database.php
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'testdb'),
'username' => env('DB_USERNAME', 'root'),
'password' => env('DB_PASSWORD', ''),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
],
我已经通过phpmyadmin创建了一个名为testdb的数据库。让我通知您,我可以打印表单字段,但是当我将上述插入代码插入数据库时,出现以下错误。
Symfony \组件\调试\异常\ FatalThrowableError (E_RECOVERABLE_ERROR)类型错误:参数1传递给 Illuminate \ Database \ Connection :: prepareBindings()必须为以下类型 数组,给定字符串,调用 C:\ Users \ regor \ ExampleProject \ vendor \ laravel \ framework \ src \ Illuminate \ Database \ Connection.php 在第665行
我将不胜感激。 :)
答案 0 :(得分:2)
DB::insert()
方法接受一个数组作为第二个参数。
您应该这样使用它:
DB::insert("INSERT INTO test(`firstname`, `surname`, `email`) VALUES(?, ?, ?)", [
$request->input('clientFirstname'),
$request->input('clientSurname'),
$request->input('clientEmail')
]);
此外,对列标识符使用反斜线代替单引号。
