Laravel或在哪里

Question

目前我正在Laravel的一个项目上工作但是我被卡住了.我想创建一个这样的SQL语句:

SELECT * FROM SPITems WHERE publisher_id=? AND feed_id=? AND (title LIKE '%?%' OR description LIKE '%?%')

现在我有这个代码:

$query = SPItem::orderBy('title');
if(isset($_GET['publisherID']) && is_numeric($_GET['publisherID']))
{
    $query = $query->where('publisher_id', $_GET['publisherID']);
}
if(isset($_GET['productFeedID']) && is_numeric($_GET['productFeedID']))
{
    $query = $query->where('program_id', $_GET['feedID']);
}
if(isset($_GET['search']))
{
    $query = $query->orWhere('title', 'like', '%' . $_GET['search'] . '%');
    $query = $query->where('description', 'like', '%' . $_GET['search'] . '%');
}

但这会产生:

SELECT * FROM SPITems WHERE (publisher_id=? AND feed_id=?) OR (title LIKE '%?%') AND description LIKE '%?%'

我怎样才能获得正确的"或"订单？

查看文档中的参数分组部分:

https://laravel.com/docs/master/queries#parameter-grouping

它解释了如何在WHERE子句中对条件进行分组.

它应该是这样的:

if(isset($_GET['search']))
{
    $query = $query->where(function($query){
        $query->where('title', 'like', '%' . $_GET['search'] . '%')
              ->orWhere('description', 'like', '%' . $_GET['search'] . '%');
    });
}
