我正在尝试对数据库实施全文搜索查询。这是我的客户发给我的规范:
"The free text search limits the result of the data table to records with a matching first
name, last name, country, city, state, or zip code. If several words are input,
each word must match one of the columns for a record to be visible."
我在我的控制器中制作了一些非常丑陋的意大利面条代码,试试它是否有效:
public function search($searchTerms){
$searchTerms = explode(' ', $searchTerms);
$results = array();
foreach ($searchTerms as $searchTerm) {
if (!People::where('firstname', 'LIKE', '%'.$searchTerm.'%')->get()->isEmpty()) {
array_push($results, People::where('firstname', 'LIKE', '%'.$searchTerm.'%')->get());
}
else if (!People::where('lastname', 'LIKE', '%'.$searchTerm.'%')->get()->isEmpty()) {
array_push($results, People::where('lastname', 'LIKE', '%'.$searchTerm.'%')->get());
}
}
return $results;
}
这是我对此功能的召唤:
$data->people = $this->search(Input::get('search'));
问题是如果没有搜索输入,我会用它来获取所有数据:
$data->people = People::orderBy($order)->paginate(10);
通过将搜索结果作为数组,我在视图中收到以下错误:
Undefined property: Illuminate\Database\Eloquent\Collection::$firstname (View: /home/projects/pplproject/app/views/index.blade.php)
如何以 Laravel方式实现?

基本上,这里的目标应该是在一个查询中运行这一切。这是:
$searchTerms = explode(' ', $searchTerms);
$query = People::query();
foreach($searchTerms as $searchTerm){
$query->where(function($q) use ($searchTerm){
$q->where('firstname', 'like', '%'.$searchTerm.'%')
->orWhere('lastname', 'like', '%'.$searchTerm.'%')
->orWhere('country', 'like', '%'.$searchTerm.'%')
// and so on
});
}
$results = $query->get();
对于相关模型,您可以尝试这样的事情:
foreach($searchTerms as $searchTerm){
$query->where(function($q) use ($searchTerm){
$q->where('firstname', 'like', '%'.$searchTerm.'%')
->orWhereHas('relationName', function($relation) use ($searchTerm){
$relation->where('relation_attribute', 'like', '%'.$searchTerm.'%');
});
});
}
