Codeigniter 分页偏移问题

Question

我的看法：

 <?php echo $this->pagination->create_links();?>

我的控制器：

public function __construct()
{
    parent:: __construct();
    $this->load->model('admin_products_model');
    $this->load->library('pagination');
}

function index()
{   
    $config['base_url'] = base_url().'products/index/';
    $config['total_rows']=$this->db->get('products')->num_rows();
    $config['per_page']=10;
    $config['num_links']=10;
    $config['use_page_numbers'] = TRUE;

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

    $page = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;
    $data['products']= $this->admin_products_model->getProducts($config['per_page'],$page); 

    $this->load->view('products',$data);
}

我的模特：

function getProducts($limit,$offset)
{
    $this->db->limit($limit);
    $this->db->offset($offset);
    $query = $this->db->get('products');

    if($query->num_rows()>0)
    {
        foreach($query->result() as $row){
            $products[]=$row;       
        }
        return $products;
    }
}

因此，当我单击导航链接时，结果 ID 不会按 10 个组升序排列。例如，第一页：85-95。第 2 页：86-96。等等。 而不是 85-95、96-106。

控制器功能：

public function index()
{
    $config ['base_url'] = base_url().'products/index/';
    $config ['total_rows'] = $this->db->get('product')->num_rows();
    $config ['uri_segment'] = 3;
    $config ['per_page'] = 10;
    $config ['num_links'] = 10;

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

    $page = $config ['per_page']; // how many number of records on page
    $segment = $this->uri->segment ( 3 ); // from which index I have to count $page number of records

    $data['products']= $this->products_model->getProducts($page, $segment); 

    $this->load->view('products', $data);
}

模型函数

public function getProducts($page, $segment)
{
    $this->db->select("prid");
    $this->db->limit($page, $segment);
    $query = $this->db->get('product');

    return $query->result();        
}

查看：

<?php
echo "<pre>";
print_r($products);
echo "</pre>";
?>
<br>
<br>
<?php echo $this->pagination->create_links();?>

您在代码中错过了 $page 和 $offset 的东西。您不必在模型中单独传递它们，在$this->db->limit($page, $offset);中提及它们
