【问题描述】:
我有一个包含多个输入和选择框的搜索表单,我需要帮助来获取我的查询中的条件,以便每个部分单独并同时工作。
这是我的刀片代码:
<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');
最后我的函数代码是:
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模特:
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模特:
public function suboptions(){
return $this->hasMany(Suboption::class, 'option_id');
}
public function products(){
return $this->belongsToMany(Product::class);
}
Suboption模特:
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 brand_id 列。
但是
我的suboptions 来自名为product_suboption 的第三张表(如您在我的模型代码中所见),我保存product_id 和suboption_id。
【问题讨论】:
-
您的复选框输入字段没有设置名称属性,因此您无法从中获取值,因为它们没有被发送。也许这会有所帮助。
-
@Reduxx 更新了我的代码。
