我使用Laravel雄辩的查询构建器，我有一个查询，我想在多个条件上有一个where子句。它能起作用，但并不优雅。
例子:
$results = User::where('this', '=', 1)
->where('that', '=', 1)
->where('this_too', '=', 1)
->where('that_too', '=', 1)
->where('this_as_well', '=', 1)
->where('that_as_well', '=', 1)
->where('this_one_too', '=', 1)
->where('that_one_too', '=', 1)
->where('this_one_as_well', '=', 1)
->where('that_one_as_well', '=', 1)
->get();
有没有更好的方法，或者我应该坚持这个方法?
当前回答
根据我的建议，如果你正在做筛选或搜索
那么你应该选择:
$results = User::query();
$results->when($request->that, function ($q) use ($request) {
$q->where('that', $request->that);
});
$results->when($request->this, function ($q) use ($request) {
$q->where('this', $request->that);
});
$results->when($request->this_too, function ($q) use ($request) {
$q->where('this_too', $request->that);
});
$results->get();

使用这个
$users = DB::table('users')
->where('votes', '>', 100)
->orWhere('name', 'John')
->get();

使用Eloquent很容易创建多个where检查:
首先:(使用简单的where)
$users = User::where('name', $request['name'])
->where('surname', $request['surname'])
->where('address', $request['address'])
...
->get();
第二个:(在数组中分组where)
$users = User::where([
['name', $request['name']],
['surname', $request['surname']],
['address', $request['address']],
...
])->get();
你也可以在里面使用条件(=，<>，等等)，就像这样:
$users = User::where('name', '=', $request['name'])
->where('surname', '=', $request['surname'])
->where('address', '<>', $request['address'])
...
->get();
一定要对子查询应用任何其他过滤器，否则or可能会收集所有记录。
$query = Activity::whereNotNull('id');
$count = 0;
foreach ($this->Reporter()->get() as $service) {
$condition = ($count == 0) ? "where" : "orWhere";
$query->$condition(function ($query) use ($service) {
$query->where('branch_id', '=', $service->branch_id)
->where('activity_type_id', '=', $service->activity_type_id)
->whereBetween('activity_date_time', [$this->start_date, $this->end_date]);
});
$count++;
}
return $query->get();
$projects = DB::table('projects')->where([['title','like','%'.$input.'%'],
['status','<>','Pending'],
['status','<>','Not Available']])
->orwhere([['owner', 'like', '%'.$input.'%'],
['status','<>','Pending'],
['status','<>','Not Available']])->get();
