添加排序依据被删除我的过滤器

Question

随着category_parent在过滤器中应用它带来的从242

results下降到13，但只要我在为了增加所花费的结果反馈给全款：

http://www.bristolfolkhouse.co.uk/results?keyword=&category_parent=6&course_week=&month=&category_child=&day=&time_of_day=&tutor=&order_by=asc

我结果的方法可以在这里找到： http://pastebin.com/G46vGRmu

这里是我的搜索表单部分： http://pastebin.com/2yaababn

我不明白为什么 - 任何人都可以帮忙吗？

代码：

Answer 1

你正在创建一个全新的查询时，你在你的代码上线83添加顺序这将覆盖$courses对象，并删除所有现有过滤器。

$courses = Course::orderBy('start_date', $request->order_by); 

您应该更改它，以便将其添加到现有查询中。它应该是这样的：

$courses = $courses->orderBy('start_date', $request->order_by); 

Answer 2

我在你的代码中发现什么，你希望有条件的顺序由创建课程模式的新查询，你犯的错误，只需更换下面的代码，

if($request->has('order_by')) { 
     $courses->orderBy('start_date', $request->order_by); 
}
