典型的搜索查询：https://mywebsite.ph/search?searchItem=marketing&criteria=bachelorsdegree&search=Search+Courses
这是我想要的搜索查询：https://mywebsite.ph/search?searchLocation=Manila
注意：mywebsite.ph不是我的网站.....我只是为了我的问题而把它放在那里。
如果我从查询中删除“searchItem”，“criteria”和“search =”，页面就会中断并出现错误。错误的例子：
缺少Illuminate \ Database \ Eloquent \ Builder :: where（）的参数1，在第1470行的/var/www/vendor/laravel/framework/src/Illuminate/Database/Eloquent/Model.php中调用并定义< / p>
使用此控制器文件构建搜索查询：

即使没有FILTER框中使用的某些查询，例如“city =”或“type =”，搜索查询也能正常工作。但是，如何才能使用“searchLocation”等特定查询使其工作？

答案 0 :(得分：0)
在某人的帮助下解决了这个问题：
在if($criteria == 'schools'){及以下
$maxPrice = (int) max($priceRanges);
}
代码：
if($searchLocation != ""){
$result=schools::where('city', 'LIKE', '%'.$searchLocation.'%')
->orderBy('name', 'asc')
->get();
$this->result = $result;
if(count($result)>0){
$count=count($result);
return view('schools', array('result' => $result, 'msg' => ''))->with(array('searchItem'=>$searchItem,'searchLocation'=>$searchLocation,'criteria'=>$criteria,'count'=>$count,'search'=>$search))->with('searchItem',$searchItem)->with(array('minPrice' =>$minPrice,'maxPrice'=>$maxPrice));
}
else{
return view('schools')->with(array('msg'=>'Oops, No result found','count'=>'0','searchItem'=>$searchItem,'searchLocation'=>$searchLocation,'criteria'=>$criteria,'search'=>$search))->with(array('minPrice' =>$minPrice,'maxPrice'=>$maxPrice));
}
}
在所有控制器文件中的'msg' => ''语句中添加了return view。
