php codeigniter pagination

Php 使用模型中的查询进行Codeigniter分页,php,codeigniter,pagination,Php,Codeigniter,Pagination,我想使用codeigniter进行分页，但没有成功。在我的模型中，我这样使用 function show_kegiatan($offset,$limit) { $query= $this->db->query("SELECT kegiatan . * , lk . * , fakultas.* , count( kegiatan_review.reviews ) AS 'Komentar', fakultas.*

limit $offset",$limit

应该是

limit $offset,$limit"

您可以使用

$this->uri->segment（3）

替换您的

$offset

请尝试此示例，其余的您必须更改以满足您的需要

在您的模型中：

function show_kegiatan($perPage, $uri) {
    $uri = ($uri == null || $uri==''?0:$uri);       
    $this->db->select('kegiatan.kolommu1,kegiatan.kolommu2,lk.kolommu1,lk.kolommu2')->from('kegiatan')->join('lk','lk.id_LK = kegiatan.id_LK')->order_by('kegiatan.id_kegiatan','desc')->limit($perPage,$uri);
    $hasil = $this->db->get()->result_array();      
    return (sizeof($hasil) > 0?$hasil:null);
}
