Php 数组laravel的分页
我正在使用Laravel,我尝试对我的产品使用分页Php 数组laravel的分页,php,laravel,Php,Laravel,我正在使用Laravel,我尝试对我的产品使用分页 array:4 [▼ 0 => Product {#770 ▶} 1 => Product {#766 ▶} 2 => Product {#814 ▶} 3 => Product {#846 ▶} ] 我用这样的方法得到这些 $this->getAllCategoriesProducts(31) 31是类别的ID 这是我的方法: public function getAllCategorie
array:4 [▼
0 => Product {#770 ▶}
1 => Product {#766 ▶}
2 => Product {#814 ▶}
3 => Product {#846 ▶}
]
我用这样的方法得到这些
$this->getAllCategoriesProducts(31)
31是类别的ID
这是我的方法:
public function getAllCategoriesProducts($cat_id){
$allProducts = [];
foreach(ProductCategory::find($cat_id)->children()->get() as $subCategory){
if($subCategory->children()->exists()){
foreach($subCategory->children()->get() as $subSubCategory){
foreach($subSubCategory->products()->get() as $product){
$allProducts[] = $product;
}
}
if($subSubCategory->children()->exists()){
foreach($subSubCategory->children()->get() as $subSubSubCategory){
foreach($subSubSubCategory->products()->get() as $product){
$allProducts[] = $product;
}
if($subSubSubCategory->children()->exists()){
foreach($subSubSubCategory->children()->get() as $subSubSubSubCategory){
foreach($subSubSubSubCategory->products()->get() as $product){
$allProducts[] = $product;
}
}
}
}
}
}
}
return $allProducts;
}
但是当我使用
$this->getAllCategoriesProducts($categroyId)->paginate(8)
它给了我这个错误
对数组上的成员函数paginate()的调用
您可以像这样手动添加分页器
use Illuminate\Pagination\LengthAwarePaginator;
$products = $this->getAllCategoriesProducts(31);
$total = count($products);
$perPage = 5; // How many items do you want to display.
$currentPage = 1; // The index page.
$paginator = new LengthAwarePaginator($products, $total, $perPage, $currentPage);

Laravel的paginator与查询生成器和雄辩的ORM集成在一起。如果您仍然每页获得整个结果集,则检查文档分页的价值是否较低。如果您能更好地描述您想要从哪些表中获取哪些数据,我们可以更好地帮助您。@online Thomas我有多级分类,因此通过上述方法,我得到了所有相关的分类产品,我想对它们进行分页,只是Thislavel的分页器与查询生成器和雄辩的ORM集成在一起。如果您仍然每页获得整个结果集,则检查文档分页的价值是否较低。如果您能更好地描述您想要从哪些表中获取哪些数据,我们可以更好地帮助您。@online Thomas我有多级分类,因此使用上述方法,我可以获得所有相关的分类产品,并且我想在下面对它们进行分页
