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?

如果你的条件是这样的(匹配一个值)，一个简单的更优雅的方式是:
$results = User::where([
'this' => value,
'that' => value,
'this_too' => value,
...
])
->get();
但如果你需要OR子句，那么确保你对每个OR where()子句重复必须满足条件。
$player = Player::where([
'name' => $name,
'team_id' => $team_id
])
->orWhere([
['nickname', $nickname],
['team_id', $team_id]
])

代码示例。
首先:
$matchesLcl=[];
数组在这里被填充使用所需的计数/循环条件，增量:
$matchesLcl['pos']= $request->pos;
$matchesLcl['operation']= $operation;
//+......+
$matchesLcl['somethingN']= $valueN;
更进一步，他又用了这样一种简洁的表达:
if (!empty($matchesLcl))
$setLcl= MyModel::select(['a', 'b', 'c', 'd'])
->where($matchesLcl)
->whereBetween('updated_at', array($newStartDate . ' 00:00:00', $newEndDate . ' 23:59:59'));
else
$setLcl= MyModel::select(['a', 'b', 'c', 'd'])
->whereBetween('updated_at', array($newStartDate . ' 00:00:00', $newEndDate . ' 23:59:59'));
使用Array的条件:
$users = User::where([
'column1' => value1,
'column2' => value2,
'column3' => value3
])->get();
将产生如下查询:
SELECT * FROM TABLE WHERE column1 = value1 and column2 = value2 and column3 = value3
使用匿名函数的条件:
$users = User::where('column1', '=', value1)
->where(function($query) use ($variable1,$variable2){
$query->where('column2','=',$variable1)
->orWhere('column3','=',$variable2);
})
->where(function($query2) use ($variable1,$variable2){
$query2->where('column4','=',$variable1)
->where('column5','=',$variable2);
})->get();
将产生如下查询:
SELECT * FROM TABLE WHERE column1 = value1 and (column2 = value2 or column3 = value3) and (column4 = value4 and column5 = value5)
我们使用这条指令根据用户类型分类和用户名两个条件来获取用户。
在这里，除了从profiles表中获取用户信息外，我们还使用两个条件在输入时进行过滤，以减少查询次数。
$users = $this->user->where([
['name','LIKE','%'.$request->name.'%'],
['trainers_id','=',$request->trainers_id]
])->with('profiles')->paginate(10);
在Eloquent中，你可以这样做:
$results = User::where('this', '=', 1)
->orWhere('that', '=', 1)
->orWhere('this_too', '=', 1)
->orWhere('that_too', '=', 1)
->orWhere('this_as_well', '=', 1)
->orWhere('that_as_well', '=', 1)
->orWhere('this_one_too', '=', 1)
->orWhere('that_one_too', '=', 1)
->orWhere('this_one_as_well', '=', 1)
->orWhere('that_one_as_well', '=', 1)
->get();
你可以像这样在匿名函数中使用子查询:
$results = User::where('this', '=', 1)
->where('that', '=', 1)
->where(
function($query) {
return $query
->where('this_too', 'LIKE', '%fake%')
->orWhere('that_too', '=', 1);
})
->get();
