Laravel高级搜索查询修复 [英] Laravel advanced search query fix
问题描述
我有一个包含多个输入和选择框的搜索表单,如果我的查询中的条件对于每个部分来说都是分开工作并且一次全部起作用,则我需要帮助.
I have a search form with multiple input and select boxes I need help to get if conditions in my query in order to each part works separately and all at once.
这是我的刀片服务器代码:
<form action="{{route('advancesearch')}}" method="post">
{{csrf_field()}}
<div class="sidebar-title">
<span>Advanced Search</span>
<i class="fa fa-caret-down show_sidebar_content" aria-hidden="true"></i>
</div>
<!-- ./sidebar-title -->
<div id="tags-filter-content" class="sidebar-content">
<div class="filter-tag-group">
@foreach($options as $option)
<div class="tag-group">
<p class="title">
<span class="filter-title show_filter_content">{{$option->title}} <span class="pull-right"><i class="fa fa-minus"></i></span></span>
</p>
<div class="filter-content">
<div class="checkbox">
@foreach($option->suboptions as $suboption)
<label for="suboptions">
<input name="suboptions[]" type="checkbox" value="{{$suboption->id}}">
{{ucfirst($suboption->title)}}
</label>
@endforeach
</div>
</div>
</div>
@endforeach
<!-- ./tag-group -->
<div class="tag-group">
<p class="title">
<span class="filter-title show_filter_content">Brand <span class="pull-right"><i class="fa fa-minus"></i></span></span>
</p>
<div class="filter-content">
<div class="checkbox">
@foreach($brands as $brand)
<label for="brands">
<input name="brands[]" type="checkbox" value="{{$brand->id}}">
{{$brand->title}}
</label>
@endforeach
</div>
</div>
</div>
<!-- ./tag-group -->
<div class="tag-group">
<p class="title">
<span class="filter-title show_filter_content">Price Range <span class="pull-right"><i class="fa fa-minus"></i></span></span>
</p>
<div class="row filter-content">
<div class="col-md-6">
<div class="form-group">
<label for="min_price" hidden>Min</label>
<input type="text" name="min_price" class="form-control" placeholder="Rp Min">
</div>
</div>
<div class="col-md-6">
<div class="form-group">
<label for="max_price" hidden>Max</label>
<input type="text" name="max_price" class="form-control" placeholder="Rp Max">
</div>
</div>
</div>
</div>
<!-- tag-group -->
<div class="text-center mt-20">
<button type="submit" class="btn btn-danger">TERPAKAN</button>
</div>
</div><!-- ./filter-tag-group -->
</div><!-- ./sidebar-content -->
</form>
这是我的路线:
Route::post('/advanced-search', 'frontend\SearchController@filter')->name('advancesearch');
最后我的功能代码是:
public function advancedsearch(Request $request) {
$brands = Brand::all(); // uses for other part of the page. (not related to search function)
$options = Option::all(); // uses for other part of the page. (not related to search function)
$suboptions = DB::table('product_suboption'); // where my product_id and subopyion_id saves
//search function
$products = Product::where(function($query){
//getting inputs
$suboptions2 = Input::has('suboptions') ? Input::get('suboptions') : [];
$min_price = Input::has('min_price') ? Input::get('min_price') : null;
$max_price = Input::has('max_price') ? Input::get('max_price') : null;
$brands2 = Input::has('brands') ? Input::get('brands') : [];
//returning results
$query->where('price','>=',$min_price)
->where('price','<=',$max_price);
})->get();
return view('front.advancesearch', compact('products', 'brands', 'options'));
}
我的模特关系:
product
型号:
public function options(){
return $this->belongsToMany(Option::class);
}
public function suboptions(){
return $this->belongsToMany(Suboption::class, 'product_suboption', 'product_id', 'suboption_id');
}
public function brand(){
return $this->belongsTo(Brand::class);
}
Option
型号:
public function suboptions(){
return $this->hasMany(Suboption::class, 'option_id');
}
public function products(){
return $this->belongsToMany(Product::class);
}
Suboption
型号:
public function option(){
return $this->belongsTo(Option::class, 'option_id');
}
public function products(){
return $this->belongsToMany(Product::class);
}
Brand
型号:
public function products(){
return $this->hasMany(Product::class);
}
注意
我的brands
搜索来自产品表,其中每个产品都有列brand_id
.
note
My brands
search is coming from products table where I have column brand_id
for each product.
但是
我的suboptions
来自名为product_suboption
的第三张表(如您在模型代码中看到的),我在其中保存了product_id
和suboption_id
.
My suboptions
come from 3rd table named product_suboption
(as you see in my models codes) where i save product_id
and suboption_id
.
推荐答案
已解决
在玩了几周的代码之后,我终于为自己找到了正确的结果(对我而言,它对其他人有用,也许对其他建议的答案也有用)
SOLVED
After weeks of playing with codes finally I came to the right results for myself (in my case it works this way for others maybe works with other suggested answers)
public function advancedsearch(Request $request) {
$options = Option::all();
$brands = Brand::all();
$brandss = Input::has('brands') ? Input::get('brands') : [];
$suboption = Input::has('suboptions') ? (int)Input::get('suboptions') : [];
$min_price = Input::has('min_price') ? (int)Input::get('min_price') : null;
$max_price = Input::has('max_price') ? (int)Input::get('max_price') : null;
//codes
if(count($request['suboptions'])){
$products = DB::table('products')
->join('product_suboption', function ($join) {
$suboption = Input::has('suboptions') ? Input::get('suboptions') : [];
$join->on('products.id', '=', 'product_suboption.product_id')
->where('product_suboption.suboption_id', '=', $suboption);
})
->paginate(12);
}
elseif(count($request['brands'])){
$products = DB::table('products')
->whereIn('products.brand_id', $brandss)
->paginate(12);
}
elseif(count($request['min_price']) && count($request['max_price'])){
$products = DB::table('products')
->whereBetween('price', [$min_price, $max_price])
->paginate(12);
}
return view('front.advancesearch', compact('products', 'brands', 'options'));
}
注意:正如我在代码
(int)Input::get('min_price')
和(int)Input::get('max_price')
.
NOTE: most of my pricing issues solved with
(int)
as you see in my codes(int)Input::get('min_price')
and(int)Input::get('max_price')
.
特别感谢 Ravindra Bhanderi 的建议.
