Question

下面是我的CI控制器代码，用于在查询中添加多个：

           $this->load->library('pagination');
            $currPage = ($this->uri->segment(4)) ? $this->uri->segment(4) : "" ;
            $config['per_page'] = 7;
            if($currPage<2)
                    $currPage = "";   

            //search
            $prjSearch = ($this->uri->segment(3)) ? $this->uri->segment(3) : "" ;
            if($prjSearch != "") {
                $this->db->like('projectName', $prjSearch, 'after');
                $this->db->like('projectName', $prjSearch, 'after');
                $this->db->like('projectName', $prjSearch, 'after');
            }
            $config['base_url'] = $this->config->site_url()."project/index/".$prjSearch."/"; 

            $this->db->select("project.*");     
            $query = $this->db->get('project',$config['per_page'],$currPage);
            $data['data'] = $query->result();
            echo $this->db->last_query();
            $config['cur_page'] = $data['cur_page'] = $currPage;
            $config['uri_segment'] = 4;
            //total count
            if($prjSearch != "") 
                $this->db->like('projectName', $prjSearch, 'after');            
            $query = $this->db->get('project');
            $config['total_rows'] = $query->num_rows();

            $this->pagination->initialize($config);

生成以下结果：

SELECT `project`.* FROM (`project`) WHERE `projectName` LIKE 'kesh%' AND `projectName` LIKE 'kesh%' AND `projectName` LIKE 'kesh%' LIMIT 7

而不是“AND”之间，我需要“OR”。

我不想使用$this->db->query();，因为CI会使分页变得复杂或不受支持任何帮助表示赞赏。

Answer 1

使用$this->db->or_like来获取它。所以改变

中的相似部分

$this->db->like('projectName', $prjSearch, 'after');
$this->db->like('projectName', $prjSearch, 'after');
$this->db->like('projectName', $prjSearch, 'after');

到这个

$this->db->or_like('projectName', $prjSearch, 'after');
$this->db->or_like('projectName', $prjSearch, 'after');
$this->db->or_like('projectName', $prjSearch, 'after');

Answer 2

试试这个

$this->db->or_like();

例如：

$this->db->like('title', 'match');
$this->db->or_like('body', $match);

所以在你的情况下，

$this->db->like('projectName', $prjSearch, 'after');
$this->db->or_like('projectName', $prjSearch, 'after');
$this->db->or_like('projectName', $prjSearch, 'after');
