使用laravel

Question

我正在尝试查询连接到我的模型“Address”的数据库，以查找在地址输入字段中输入到我的表单中的任何地址。我的型号代码是：

public function CheckForPrevious($verify)

{
  $matches = \App\Address::where('address', 'like', '%'.$verify.'%')

  ->get();

  foreach($matches as $match)
  {
    echo "$match";
  }



}

我的控制器代码是：

public function show()
    {
      $address = new Address;
      $check = $_POST['address'];

      $address->CheckForPrevious($check);

      return $address;

    }

非常感谢任何帮助

Answer 1

public function show()
{
  $address = new Address();
  $check = $_POST['address'];

  $address->scopeCheckForPrevious($check);

}

public function scopeCheckForPrevious（$ verify）

    {
      $query = App\Address::where('address', 'like', '%'.$verify.'%')

      ->get();

      foreach($query as $match)
      {
        echo "$match";
      }



    }

使用此

Answer 2

您不必在scope前加上查询范围函数

更改

  `$address->scopeCheckForPrevious($check)`

要

  `$address->CheckForPrevious($check)`

Answer 3

无需访问范围上不必要的模型
$query = App\Address::where('address', 'like', '%'.$verify.'%')

试试这样：

public function scopeCheckForPrevious($query, $verify)
{
    return $query->where('address', 'like', '%'.$verify.'%');
}

并使用以下代码调用它：

$address = new Address;
$check = $_POST['address'];
dd( $address->checkForPrevious($check)->get() );
