Bah*_*eza 1 search full-text-search codeigniter sql-like
我有一个查询,可以使用like搜索关键字,但是我也想搜索全文,因此我将其更改为全文搜索查询,但是它不起作用。
工作正常的旧查询:
$data = $this->db
->select('content.title,content.id,content.category,content.body,path')
->from('content')
->join('categories','content.category = categories.id')
->like('content.title', $searchterm)
->like('content.body', $searchterm)
->order_by("content.id","DESC")
->get();

这是我对全文搜索的新查询:
$data = $this->db
->select('content.title,content.id,content.category,content.body,path')
->from('content')
->join('categories','content.category = categories.id')
->where('MATCH (content.body, content.title) AGAINST ("'. $searchterm .'")')
->order_by("content.id","DESC")
->get();

where()需要3个参数,例如:
$this->db->where('MATCH (field) AGAINST ("value")', NULL, FALSE);
$this->db->get('table');
Run Code Online (Sandbox Code Playgroud)match()触发器中的多个列错误号:1191,因此将它们分开:
->where('MATCH (content.title) AGAINST ("'. $searchterm .'")')
->where('MATCH (content.body) AGAINST ("'. $searchterm .'")')
