[英]Laravel 5 search results pagination
I have created some search filters using a textbox and drop downs so when I click the search button i want to use any of these filters to query eloquent relationships. 我已经使用文本框和下拉列表创建了一些搜索过滤器,因此当我单击搜索按钮时,我想使用这些过滤器中的任何一个来查询雄辩的关系。
The search works fine and I get the correct amount of results but the problem lies with the pagination. 搜索工作正常,我得到正确数量的结果,但问题出在分页上。 When I click on the next page button (or any other page), the result is result and I get everything again. 当我单击下一页按钮(或任何其他页面)时,结果就是结果,我又得到了一切。
I know this because I'm not doing a request when the paging is clicked so my question is how do i perform so same query but using the paging? 我知道这是因为单击分页时我没有执行请求,所以我的问题是如何执行相同的查询但使用分页?
Here is my controller function 这是我的控制器功能
public function index(Request $request)
{
if(!empty($request)) {
$products = Product::with(['supplier', 'carrier', 'name']);
if($request->name) {
$products = $products->whereHas('Name', function ($query) use ($request) {
$products = $query->where('Name', $request->name);
});
}
if($request->subtype) {
$products = $products->whereHas('SubType', function ($query) use ($request) {
$products = $query->where('SubTypeId', $request->subtype);
});
}
if($request->supplier) {
$products = $products->whereHas('Supplier', function ($query) use ($request) {
$products = $query->where('SupplierId', $request->supplier);
});
}
if($request->carrier) {
$products = $products->whereHas('Carrier', function ($query) use ($request) {
$products = $query->where('CarrierId', $request->carrier);
});
}
$products = $products->paginate(8);
}
else {
$products = Product::with(['supplier', 'carrier', 'name'])->paginate(8);
}
$suppliers = Supplier::all();
$carriers = Carrier::all();
$subtypes = SubType::all();
$options = array(
'products' => $products,
'suppliers' => $suppliers,
'subtypes' => $subtypes,
'carriers' => $carriers
);
return view('products.index')->with($options);
}
I was able to fix it by changing the controller function. 我可以通过更改控制器功能来修复它。 I didn't the IF statement 我没有IF声明
$products = Product::with(['supplier', 'carrier', 'name']);
if($request->name) {
$products = $products->whereHas('Name', function ($query) use ($request) {
$query->where('Name', $request->name);
});
}
if($request->subtype) {
$products = $products->whereHas('SubType', function ($query) use ($request) {
$query->where('SubTypeId', $request->subtype);
});
}
if($request->supplier) {
$products = $products->whereHas('Supplier', function ($query) use ($request) {
$query->where('SupplierId', $request->supplier);
});
}
if($request->carrier) {
$products = $products->whereHas('Carrier', function ($query) use ($request) {
$query->where('CarrierId', $request->carrier);
});
}
$products = $products->paginate(8);
$suppliers = Supplier::all();
$carriers = Carrier::all();
$subtypes = SubType::all();
$options = array(
'products' => $products,
'suppliers' => $suppliers,
'subtypes' => $subtypes,
'carriers' => $carriers
);
return view('products.index')->with($options);
In my view where I put the pagination link, I replaced 在我认为放置分页链接的位置,我替换了
{{ $products->links() }}
with 同
{{ $products->appends(\Request::except('_token'))->render() }}
