Codeigniter中的搜索分页无法正常工作

Question

我在codeigniter中搜索分页时遇到问题

• 选择其他页面链接

时，网址不会更改

• 选择其他链接时数据不会改变

这是我的控制器

public function search_code(){

    $this->load->library('pagination');
    $param = new stdClass();
    $param->item_code = $this->input->get('by_item_code');
    $param->description = $this->input->get('by_description');

    if (!isset($page) || $page == '') {
        $page = 1;
    }
    $param->per_page = 50;
    $param->limit = ($page - 1) * $param->per_page;

    $paginate_url = base_url('warehouse/search_code?item_code='.$param->item_code.'&by_description='.$param->description.'&page='.($page+1));

    $data['total_result'] = $this->m_stock->count_stock_search ($param);

    $config['uri_segment'] = 3;
    $config['num_links'] = 4;
    $config['base_url'] = $paginate_url;
    $config['total_rows'] = $data['total_result'];
    $config['per_page'] = $param->per_page;
    $config['use_page_numbers'] = TRUE;
    $config['page_query_string'] = TRUE;

    $this->pagination->initialize($config);
    $data['pagination'] = $this->pagination->create_links();

    $data['item'] = $this->m_stock->search_code ($param);
    $this->load->view('v_all_stocks', $data);
}

这是我的模特

function search_code($param){

    $result = array();
    $sql = "select ic.id, ic.item_code, ic.description, maxdt.maxdt, lc.balance,lc.dt,lc.createdate,lc.id_lines_code, io.ONHANDQTY ";
    $sql .= "from tbl_item_code ic ";
    $sql .= "left join ( tbl_lines_code lc inner join ( select id, max(createdate) maxdt from tbl_lines_code where active = 1 group by id ) maxdt ";
    $sql .= "on lc.id = maxdt.id and lc.createdate = maxdt.maxdt ) on ic.id = lc.id ";
    $sql .= "left join item_ostendo io on io.ITEMCODE = ic.item_code ";
    $sql .= "where ic.active = 1 ";

    if ($param->item_code != '') {
        $sql .= "AND ic.item_code LIKE '%$param->item_code%' ";
    }
    if ($param->description != '') {
        $sql .= "AND ic.description LIKE '%$param->description%' ";
    }
    $sql .= "group by ic.id order by ic.item_code ";
    if ($param->limit > 0)
        $sql .= " LIMIT ".$param->limit.", ".$param->per_page;
    else
        $sql .= " LIMIT ".$param->per_page;
    $query = $this->db->query($sql);

    if ($query->num_rows() > 0) {
        $result = $query->result();
    }

    return $result;

}

和关于视图我检查它可以工作 但我不知道为什么我选择数字的链接，数据显示像最后一页，但链接的数量正在工作

显示所有数据尚未搜索链接显示如下

当搜索显示为时 但是当选择第2个链接时，它会显示为，每个页面的数据相同

Answer 1

你需要改变你的：

$paginate_url = base_url('warehouse/search_code?item_code='.$param->item_code.'&by_description='.$param->description.'&page='.($page+1));

此：

$config['uri_segment'] = 3;

为offset子句定义该段。

我建议：

$query = "?item_code='.$param->item_code.'&by_description='.$param->description.'&page='.($page+1))";
$paginate_url = base_url('warehouse/search_code/page/').$query;
$config['uri_segment'] = 4;

将此作为抵消：

$param->limit = $this->uri->segment(4); 

Answer 2

您必须更改分页基本网址，如下所示：

    $paginate_url = base_url('warehouse/search_code').'?item_code='.$param->item_code.'&by_description='.$param->description;
