我尝试为用户创建搜索引擎。搜索将包含多个字段,以便用户可以选择他想要的任何内容并获得结果。合并多个查询(Laravel 5)

routes.php文件:

Route::get('search/{tag?}/{town?}/{education?}/{contract?}', '[email protected]'); 

DisplayJobs.php控制器

public function getSearch($tag = null, $town = null, $education = null, $contract = null) 
{ 
    //get already database values to send them to the form 
    $tags = \App\Tag::lists('name', 'id'); 
    $contract = \App\Contract::lists('name', 'id'); 
    $towns = \App\Town::lists('name', 'id'); 
    $education = \App\Education::lists('name', 'id'); 

    $tagQueryBuilder = Tag::query(); 
    $townQueryBuilder = Town::query(); 
    $educationQueryBuilder = Education::query(); 
    $contractQueryBuilder = Contract::query(); 

    if(Input::has('tag')) 
    { 
     $tagQueryBuilder->TagOfUser(Input::get('tag')); 
    } 
    if(Input::has('town')) 
    { 
     $townQueryBuilder->TownOfUser(Input::get('town')); 
    } 
    if(Input::has('education')) 
    { 
     $educationQueryBuilder->EducationOfUser(Input::get('education')); 
    } 
    if(Input::has('contact')) 
    { 
     $contractQueryBuilder->ContactOfUser(Input::get('contact')); 
    } 


    return view('main.search_jobs', compact('tags', 'towns', 'contract', 'education')); 

} 

如果我尝试用它完美的每个单独的查询,但我想综合作用的结果数据从所有查询或一次查询所有数据的方式。

在每一个模型,我有我的查询范围是这样(Tag.php)型号

public function jobs() 
{ 
    return $this->belongsToMany('App\Job'); 
} 

public function scopeTagOfUser($query, $tag) 
{ 
    return $query->where('id', '=', $tag)->with('jobs'); 
}

你的问题不明确。你想要所有查询的组合结果数据,还是想要一种方法一次查询所有数据?此外,'\ App \ Something :: lists('name','id');'工作,这让我想知道,你甚至没有运行代码? – JSelser

谢谢你的回复。所有代码\ App \ Something :: lists('name','id');完美的作品,我尝试过。我只想结合所有查询的结果数据或一次查询所有数据的方法。 –

此外,它适用于每个单一的查询。 –

了很多小时后,我找到了解决办法。我会在下面发布,所以如果任何人有同样的问题可以看到一个解决方案。

首先我必须删除所有的车型范围查询,并完成所有的控制器像波纹管的工作:

public function getSearch($tag = null, $town = null, $education = null, $contract = null) 
{ 
    //get already database values to send them to the form 
    $tags = \App\Tag::lists('name', 'id'); 
    $towns = \App\Town::lists('name', 'id'); 
    $contract = \App\Contract::lists('name', 'id'); 
    $education = \App\Education::lists('name', 'id'); 

    //get inputs from users 
    $getTagFromUser = Input::get('tag'); 
    $getTownFromUser = Input::get('town'); 
    $getContractFromUser = Input::get('contract'); 
    $getEducationFromUser = Input::get('education'); 

    $tagQuery = DB::table('jobs') 
     ->join('job_tag', 'jobs.id', '=', 'job_tag.job_id') 
     ->join('tags', 'job_tag.tag_id', '=', 'tags.id') 
     ->where('tags.id', '=', $getTagFromUser); 

    $townQuery = DB::table('jobs') 
     ->join('job_town', 'jobs.id', '=', 'job_town.job_id') 
     ->join('towns', 'job_town.town_id', '=', 'towns.id') 
     ->where('towns.id', '=', $getTownFromUser); 

    $contractQuery = DB::table('jobs') 
     ->join('job_contract', 'jobs.id', '=', 'job_contract.job_id') 
     ->join('contracts', 'job_contract.contract_id', '=', 'contracts.id') 
     ->where('contracts.id', '=', $getContractFromUser); 

    $educationQuery = DB::table('jobs') 
     ->join('job_education', 'jobs.id', '=', 'job_education.job_id') 
     ->join('education', 'job_education.education_id', '=', 'education.id') 
     ->where('education.id', '=', $getEducationFromUser); 


    $finalQuery = $tagQuery->union($townQuery)->union($contractQuery)->union($educationQuery)->get(); 


    return view('main.search_jobs', compact('tags', 'towns', 'contract', 'education', 'finalQuery')); 

}
