php - CI-Bonfire 嵌套 LIKE 查询

Question

在嵌套类似查询时，我可能需要一点帮助。我的目标是完成类似以下的事情：

Select * from 'Library_Book'

WHERE(
    ('BookName' LIKE '%FILTER1%' OR 'BookDescription' LIKE '%FILTER1%')
AND 
    ('BookName' LIKE '%FILTER2%' OR 'BookDescription' LIKE '%FILTER2%')
)

到目前为止，我的方法是：

$this->db->select('Library_Book.*');
foreach($filter as $fltr){
    $this->db->like('Library_Book.BookName', $fltr);
    $this->db->or_like('Library_Book.BookDescription', $fltr);
}
$records = $this->find_all();

这导致：

Select * from 'Library_Book'

WHERE(
    'BookName' LIKE '%FILTER1%' OR 'BookDescription' LIKE '%FILTER1%'
AND 
    'BookName' LIKE '%FILTER2%' OR 'BookDescription' LIKE '%FILTER2%'
)

我怎样才能得到我的 or_like 语句周围的括号？

谢谢

Bonfire 的 lonnieezell 给出了答案。

我测试了它并且它有效。

$wheres = array();
foreach ($filter as $fltr)
{
    $wheres[] = "('BookName' LIKE '%{$fltr}%'' OR 'BookDescription' LIKE '%{$fltr}%')";
}

$this->db->where( implode(' AND ', $wheres), null, false);
$records = $this->find_all();
