七爪源码:Laravel 提示和技巧（laravel框架菜鸟教程）

重要笔记

1-) 嵌套 Foreach 和嵌套 Map

Map ：

$result->children->map(function ($item) {
    // do some stuff with $item or you can no map through its children
    $item->children->map(function ($nestedItem) {
        // do some stuff with $nestedItem etc//
    });
});

Foreach :

• 看法

@foreach ($result as $children)
 @foreach ($children->posts as $nestedItem)
 
 @endforeach
@endforeach

• 控制器

foreach($result as $children){
  foreach($children->posts as $nestedItem){  }
}

2-) HTTP 客户端

假设我们使用 curl 发送 api 请求，您的代码如下：

$veri = json_encode($veri);
 $ch = curl_init($moka_url); 
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
 curl_setopt($ch, CURLOPT_POST, 1); 
 curl_setopt($ch, CURLOPT_POSTFIELDS, $veri);
 curl_setopt($ch, CURLOPT_HTTPHEADER, array(‘Content-Type:application/json’));
 curl_setopt($ch, CURLOPT_SSLVERSION, 6); // TLS 1.2 baglanti destegi icin
 curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); // VerifyPeer = 0 kalmal?
 $result = curl_exec ($ch); 
 curl_close ($ch);
 $result = json_decode($result);

如果我们改用 HTTP 客户端，我们只需一行代码就可以完成工作：

$result = Http::accept('Content-Type:application/json')
->post($moka_url,$veri);

3-) 关键字搜索范围

模型文件：

public function scopeWhereFilters($query, array $filters)
{
    $filters = collect($filters);

    $query->when($filters->get('keyword'), function ($query, $search) {
        $query->whereKeyword($search);
    });
}

和

public function scopeWhereKeyword($query, $keyword)
{
    foreach (explode(' ', $keyword) as $term) {
        $query->where(function ($query) use ($term) {
            $query->where('order_no', 'like', '%' . $term . '%')
                ->orWhere('order_name', 'like', '%' . $term . '%')
                ->orWhere('barcode', 'like', '%' . $term . '%')
                ->orWhere('product_name', 'like', '%' . $term . '%')
   
                ->WhereHas('user', function ($t2) use ($term) {
                    $t2->Where('name', 'like', '%' . $term . '%');
                    $t2->orWhere('email', 'like', '%' . $term . '%');
                });
        });
    }
}

雄辩的查询：（在控制器中）

$orders = Order::with(['product'])
     ->whereFilters($request->only('keyword'))
     ->where('order_status', 1)
     ->orderBy('id', 'asc')
     ->get();

注意：必须获取路由类型

奖励：将 Artisan 命令添加到面板

路由.php：

Route::group([
 ‘middleware’ => [‘auth’, ‘role:superadmin’, ‘verified’]
 ], function () {Route::get(‘cache-clear’, function () {
 \Artisan::call(‘cache:clear’);
 return redirect(‘/admin/home’)->with(‘success’, Artisan::output());
 });Route::get(‘optimize-clear’, function () {
 \Artisan::call(‘optimize:clear’);
 return redirect(‘/admin/home’)->with(‘success’, Artisan::output());
 });Route::get(‘optimize’, function () {
 \Artisan::call(‘optimize’);
 return redirect(‘/admin/home’)->with(‘success’, Artisan::output());
 });});
