How to create filter with easy way in laravel 8 using controller and checkbox - laravel

Question

I am creating filter for the products, I tried using jquery for this before but I am not able to fix the pagination in laravel. So, I am trying this to fix the pagination as well as reduce the database query, bcoz in jquery everytime I click on any category or sub category, then it hits the database so the number of execution was more, So I replace the jquery and trying to use the button to do the same. But stuck with the array.
Can anyone help me with this?
$category = ["p1","p2","p3"];
$sub_category = ["c1","c2","c3","c4"];
$data = [];
$count = 0;
foreach ($cate as $category){
$data2 =[];
$count1 = 0;
foreach ($sub_cate as $sub){
$data2[] = [
'sub_category_id' => $category.$count1++,
'sub_category' => $sub,
'url' => $category.'|'.$sub
];
}
$data[] = [
'category_id' => 'category_'.$count++,
'category' => $category,
'sub_category' => $data2
];
}
In blade file :
#foreach($filters as $filter)
<div class="custom-control custom-checkbox mb-2">
<input type="checkbox" class="custom-control-input category_filter1" id={{$filter["category_id"]}} name="category_filter[]" value="{{$filter["category"]}}">
<label class="custom-control-label w-100" for="{{$filter["category_id"]}}">{{$filter["category"]}}</label>
#foreach($filter["sub_category"] as $sub)
<div class="custom-control custom-checkbox mb-2">
<input type="checkbox" class="custom-control-input category_filter1" id={{$sub["sub_category_id"]}} name="sub_category_filter[]" value="{{$sub["url"]}}">
<label class="custom-control-label w-100" for="{{$sub["sub_category_id"]}}">{{$sub["sub_category"]}}</label>
</div>
#endforeach
</div>
#endforeach
After using this code I am getting this type of data :
{"category_filter":["p1","p2"],"sub_category_filter":["p1|c1","p1|c2","p1|c3","p1|c1"]}
So basically the array structure is like this :
For now everything looks nice but, When I try to combine the array into once then it look some time to sort and rearrange itself, So it there any easy way to this, Each time I change the filters it will take time and then it fetch result from the database. For some reason I thought that URL which is custom made will help me but it only taking us to the wrong direction.

Answer 1

apply condition in conrtoller like this
if($request->input('category_filter') == "p1"){
if($request->input('sub_category_filter') == "p1|c1"){
... do your code as per your need
}
}
I share Sample Example:
assume I want to filter data like All, approved, pending, decline... then I write script in controller like this
if($request->input('filtertype')){
$filtertype = $request->input('filtertype');
if($filtertype == "All"){
$deals = Deal::orderBy('updated_at', 'desc')->get();
}else{
$deals = Deal::where('deal_isApproved', '=', $filtertype)
->orderBy('updated_at', 'desc')->get();
}
}
return view('admin.deals.index',compact('deals'));
