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
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();
其他回答
您可以在where子句中使用数组，如下所示。
$result=DB::table('users')->where(array(
'column1' => value1,
'column2' => value2,
'column3' => value3))
->get();
查询作用域可以帮助您提高代码的可读性。
http://laravel.com/docs/eloquent#query-scopes
用一些例子更新这个答案:
在你的模型中，像这样创建作用域方法:
public function scopeActive($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();
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]
])
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();
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();
