我有2个班级:
带有一些函数的class.user.php:
<?php
require_once 'dbconfig.php';
date_default_timezone_set('Europe/Brussels');
class USER
{
private $conn;
public function __construct()
{
$database = new Database();
$db = $database->dbConnection();
$this->conn = $db;
}
带有函数的class.paginator.php:
<?php
date_default_timezone_set('Europe/Brussels');
class Paginator {
private $_conn;
private $_limit;
private $_page;
private $_query;
private $_total;
public function __construct( $conn, $query ) {
$this->_conn = $conn;
$this->_query = $query;
$rs= $this->_conn->query( $this->_query );
$this->_total = $rs->num_rows;
}
public function getData( $limit = 10, $page = 1 ) {
$this->_limit = $page;
$this->_page = $limit;
if ( $this->_limit == 'all' ) {
$query = $this->_query;
} else {
$query = $this->_query . " LIMIT " . ( ( $this->_page - 1 ) * $this->_limit ) . ", $this->_limit";
}
$rs = $this->_conn->query( $query );
while ( $row = $rs->fetch_assoc() ) {
$results[] = $row;
}
$result = new stdClass();
$result->page = $this->_page;
$result->limit = $this->_limit;
$result->total = $this->_total;
$result->data = $results;
return $result;
}
public function createLinks( $links, $list_class ) {
if ( $this->_limit == 'all' ) {
return '';
}
$last = ceil( $this->_total / $this->_limit );
$start = ( ( $this->_page - $links ) > 0 ) ? $this->_page - $links : 1;
$end = ( ( $this->_page + $links ) < $last ) ? $this->_page + $links : $last;
$html = '<ul class="' . $list_class . ' custom-pagination">'
. '<select id="itemspage" class="form-control">
<option value="5">5</option>
<option value="10" selected>10</option>
<option value="15">15</option>
<option value="25">25</option>
<option value="50">50</option>
</select>';
$class = ( $this->_page == 1 ) ? "hidden" : "";
$html .= '<li class="' . $class . '"><a href="?limit=' . $this->_limit . '&page=' . ( $this->_page - 1 ) . '">«</a></li>';
if ( $start > 1 ) {
$html .= '<li><a href="?limit=' . $this->_limit . '&page=1">1</a></li>';
$html .= '<li class="disabled"><span>...</span></li>';
}
for ( $i = $start ; $i <= $end; $i++ ) {
$class = ( $this->_page == $i ) ? "active" : "";
$html .= '<li class="' . $class . '"><a href="?limit=' . $this->_limit . '&page=' . $i . '">' . $i . '</a></li>';
}
if ( $end < $last ) {
$html .= '<li class="disabled"><span>...</span></li>';
$html .= '<li><a href="?limit=' . $this->_limit . '&page=' . $last . '">' . $last . '</a></li>';
}
$class = ( $this->_page == $last ) ? "hidden" : "";
$html .= '<li class="' . $class . '"><a href="?limit=' . $this->_limit . '&page=' . ( $this->_page + 1 ) . '">»</a></li>';
$html .= '</ul>';
return $html;
}
}
对于分页,我使用以下代码:
require_once 'class.paginator.php';
$conn = new mysqli( 'localhost', 'user', 'password', 'database' );
$limit = ( isset( $_GET['limit'] ) ) ? $_GET['limit'] : 10;
$page = ( isset( $_GET['page'] ) ) ? $_GET['page'] : 1;
$links = ( isset( $_GET['links'] ) ) ? $_GET['links'] : 7;
$query = "SELECT * FROM sbs INNER JOIN city ON sbs.sbs_city=city.city_id WHERE sbs_subcat='afhaal' AND sbs_status=1 AND sbs_country=$country";
$Paginator = new Paginator( $conn, $query );
$results = $Paginator->getData( $page, $limit );
结果显示良好
链接是这个代码:
<?php echo $Paginator->createLinks( $links, 'pagination pagination' ); ?></center>
我想结合这两个类,所以我只需要使用一个类(class.user.php)
dbconfig.php就像:
private $host = "localhost";
private $db_name = "database";
private $username = "username";
private $password = "password";
public $conn;
public function dbConnection()
{
$this->conn = null;
try
{
$this->conn = new PDO("mysql:host=" . $this->host . ";dbname=" . $this->db_name . ";charset=utf8", $this->username, $this->password);
$this->conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
}
catch(PDOException $exception)
{
echo "Connection error: " . $exception->getMessage();
}
return $this->conn;
}
我只是在使用__construct()...将函数放在一起不是问题。
先谢谢你的帮助!
