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?

多个where子句
$query=DB::table('users')
->whereRaw("users.id BETWEEN 1003 AND 1004")
->whereNotIn('users.id', [1005,1006,1007])
->whereIn('users.id', [1008,1009,1010]);
$query->where(function($query2) use ($value)
{
$query2->where('user_type', 2)
->orWhere('value', $value);
});
if ($user == 'admin'){
$query->where('users.user_name', $user);
}
终于得到了结果
$result = $query->get();

查询作用域可以帮助您提高代码的可读性。
http://laravel.com/docs/eloquent#query-scopes
用一些例子更新这个答案:
在你的模型中，像这样创建作用域方法:
public function scopeActive($query)
{
return $query->where('active', '=', 1);
}
public function scopeThat($query)
{
return $query->where('that', '=', 1);
}
然后，你可以在构建查询时调用这个作用域:
$users = User::active()->that()->get();
$projects = DB::table('projects')->where([['title','like','%'.$input.'%'],
['status','<>','Pending'],
['status','<>','Not Available']])
->orwhere([['owner', 'like', '%'.$input.'%'],
['status','<>','Pending'],
['status','<>','Not Available']])->get();
您可以在where子句中使用数组，如下所示。
$result=DB::table('users')->where(array(
'column1' => value1,
'column2' => value2,
'column3' => value3))
->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();
Model::where('column_1','=','value_1')
->where('column_2 ','=','value_2')
->get();
OR
// If you are looking for equal value then no need to add =
Model::where('column_1','value_1')
->where('column_2','value_2')
->get();
OR
Model::where(['column_1' => 'value_1',
'column_2' => 'value_2'])->get();
