codeigniter 1的分页错误

Question

在模型/rci_model.php 中

public function record_count() {
return $this->db->count_all("produk");
}

public function fetch_countries($limit, $start) {
    $this->db->limit($limit, $start);
     $query=$this->db->query("SELECT * FROM produk WHERE id_kategori='Men' order by nama_produk ASC");
        return $query->result();

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

在控制器/sandal_clarudo.php 中

function sandals_for_men(){
$data['seo'] = $this->rci_model->tampil_meta(22);
$this->load->view('head', $data);
$config = array();
$config["base_url"] = "http://localhost/clarudo/index.php/sandal_clarudo/sandals_for_men/";
$config["total_rows"] = $this->rci_model->record_count();
$config["per_page"] = 5;
$config["uri_segment"] = 3;

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

$page = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;
$data["results"] = $this->rci_model->
    fetch_countries($config["per_page"], $page);
$data["links"] = $this->pagination->create_links();
$this->load->view('men', $data);
$this->load->view('footer');
}

在视图/men.php

<?php
foreach($results as $t){
echo "$t->nama_produk";
}

我只想显示类别 = 'Men' 的产品，但使用我的代码会显示所有类别的产品。想法？

Answer 1

试试这个

在控制器中

$count = $this->rci_model->get_count(); //get number of rows

$config['base_url'] = base_url().'index.php/sandal_clarudo/sandals_for_men/';
$config['total_rows'] = $count;
$config['per_page'] = 5;
$config['uri_segment'] = 3;
$limit = $config['per_page'];

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

$page = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;

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

$data["results"] = $this->rci_model->fetch_countries($limit, $page);

在模型中

public function get_count() 
{
  //count          
$query=$this->db->query("SELECT * FROM produk WHERE id_kategori='Men'");
$result = $query->result_array();
$count = count($result);
 return $count;
}
//data from table
public function fetch_countries($limit, $page) 
{
$query=$this->db->query("SELECT * FROM produk WHERE id_kategori='Men' LIMIT $page, $limit");
$result = $query->result_array();
return $result;
}

在视图中

//to show data
<?php
foreach ($results as $new_result)
{
echo $new_result['nama_podak'];
}
?>

//to show pagination
<?php
echo $link//Page segment tabs(you can config boostarp for this)
?>

Answer 2

试试这个。你用limit的时候错了。

$query=$this->db->query("SELECT * FROM produk WHERE id_kategori='Men' order by nama_produk ASC LIMIT $limit, $start");

Answer 3

$this->db->limit($limit, $start);
$this->db->where('id_kategori', 'men');
$this->db->order_by('nama_produk');
$query = $this->db->get("produk");

希望这项工作！

计数使用：

public function record_count($limit, $start) {
            $this->db->from('count(id_produk) AS count');
            $this->db->where('id_kategori', 'men');
            $this->db->order_by('nama_produk');
            $this->db->limit($limit, $start);
            $return = $query->row_array();
            return $return['count'];
        }
