本文介绍了Laravel 高级搜索查询修复的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着跟版网的小编来一起学习吧！
问题描述
我有一个包含多个输入和选择框的搜索表单，我需要帮助来获取查询中的条件，以便每个部分单独工作并同时工作.
这是我的刀片代码:
我有一个包含多个输入和选择框的搜索表单，我需要帮助来获取查询中的条件，以便每个部分单独工作并同时工作.
这是我的刀片代码:
<!-- ./sidebar-title --><div id="tags-filter-content" class="sidebar-content"><div class="filter-tag-group">@foreach($options 作为 $option)<div class="tag-group"><p class="title"><span class="filter-title show_filter_content">{{$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)}}@endforeach

<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">
<!-- 标签组--><div class="text-center mt-20"><button type="submit" class="btn btn-danger">TERPAKAN</button>
</div><!-- ./filter-tag-group --></div><!-- ./sidebar-content --></表单>
这是我的路线:
Route::post('/advanced-search', 'frontendSearchController@filter')->name('advancesearch');最后我的函数代码是:
公共函数advancedsearch(Request $request) {$brands = Brand::all();//用于页面的其他部分.(与搜索功能无关)$options = Option::all();//用于页面的其他部分.(与搜索功能无关)$suboptions = DB::table('product_suboption');//我的 product_id 和 subopyion_id 保存在哪里//搜索功能$products = Product::where(function($query){//获取输入$suboptions2 = Input::has('suboptions') ?Input::get('suboptions') : [];$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') : [];//返回结果$query->where('price','>=',$min_price)->where('price','<=',$max_price);})->get();return view('front.advancesearch', compact('products', 'brands', 'options'));}product 型号:
公共函数选项(){返回 $this->belongsToMany(Option::class);}公共功能子选项(){返回 $this->belongsToMany(Suboption::class, 'product_suboption', 'product_id', 'suboption_id');}公共功能品牌(){返回 $this->belongsTo(Brand::class);}Option 模型:
公共函数子选项(){返回 $this->hasMany(Suboption::class, 'option_id');}公共功能产品(){返回 $this->belongsToMany(Product::class);}子选项模型:
公共函数选项(){返回 $this->belongsTo(Option::class, 'option_id');}公共功能产品(){返回 $this->belongsToMany(Product::class);}品牌型号:
公共功能产品(){返回 $this->hasMany(Product::class);}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 的第三个表(如您在我的模型代码中看到的)，我在其中保存了 product_id 和 suboption_id.
在玩了数周的代码之后，我终于为自己找到了正确的结果(在我的情况下，它对其他人有效，可能适用于其他建议的答案)
公共函数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;$max_price = Input::has('max_price') ?(int)Input::get('max_price') : null;//代码if(count($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', '=', $suboption);})-> 分页(12)；}elseif(count($request['brands'])){$products = DB::table('products')->whereIn('products.brand_id', $brandss)-> 分页(12)；}elseif(count($request['min_price']) && count($request['max_price'])){$products = DB::table('products')->whereBetween('price', [$min_price, $max_price])-> 分页(12)；}return view('front.advancesearch', compact('products', 'brands', 'options'));}<块引用>
注意:我的大部分定价问题都是用 (int) 解决的，正如你在我的代码中看到的 (int)Input::get('min_price') 和(int)Input::get('max_price').
特别感谢 Ravindra Bhanderi 的 count($request[''] 建议.
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.
here is my blade codes:
<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>
and this is my route:
Route::post('/advanced-search', 'frontendSearchController@filter')->name('advancesearch');
finally my function code is:
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'));
}
product model:
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 model:
public function suboptions(){
return $this->hasMany(Suboption::class, 'option_id');
}
public function products(){
return $this->belongsToMany(Product::class);
}
Suboption model:
public function option(){
return $this->belongsTo(Option::class, 'option_id');
}
public function products(){
return $this->belongsToMany(Product::class);
}
Brand model:
public function products(){
return $this->hasMany(Product::class);
}
My brands search is coming from products table where I have column brand_id for each product.
BUT
My suboptions come from 3rd table named product_suboption (as you see in my models codes) where i save product_id and suboption_id.
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, $max_price])
->paginate(12);
}
return view('front.advancesearch', compact('products', 'brands', 'options'));
}
NOTE: most of my pricing issues solved with
(int)as you see in my codes(int)Input::get('min_price')and(int)Input::get('max_price').
Special thanks to Ravindra Bhanderi for his count($request[''] suggestion.
