laravel的 orderBy('a','desc'),我如果还想在a一样的情况下,同时根据b降序排序要怎么写


回复讨论(解决方案)

orderBy 方法(Builder.php)被写作

	public function orderBy($column, $direction = 'asc')	{		$this->orders[] = compact('column', 'direction');		return $this;	}

所以可以这样写
...->orderBy('a','desc')->orderBy('b','desc')->...
这样写应该也可以
...->orderBy(['a', 'b'], ['desc', 'desc'])->...

orderBy 方法(Builder.php)被写作

	public function orderBy($column, $direction = 'asc')	{		$this->orders[] = compact('column', 'direction');		return $this;	}

所以可以这样写
...->orderBy('a','desc')->orderBy('b','desc')->...
这样写应该也可以
...->orderBy(['a', 'b'], ['desc', 'desc'])->...

非常感谢,结贴给分!

非常感谢,结贴给分! 第二种方式貌似不行strtolower() expects parameter 1 to be string, array given,只能用第一种了。
