如何在這段代碼實現分頁：實現分頁的PHP
<?php
include "connect.php";
$query = mysql_query("SELECT username, date FROM users ORDER BY id ASC");
while($row = mysql_fetch_array($query)):
?>
<div><h5><?php echo $row['username']; ?> (<?php echo $row['date']; ?>)</h5></div>
<?php endwhile; ?>
的想法是與MySQL LIMIT關鍵字玩。它可以讓你限制你從mysql獲得的結果的數量。
SELECT data FROM table LIMIT 5
相當於
SELECT data FROM table LIMIT 0, 5
其中0是偏移量和5由MySQL返回的行的數量。
所以，你必須解決一些項目顯示，假設$numRes = 10和頁碼：
if (isset($_GET['page']) && is_numeric($_GET['page']))
$page = $_GET['page'];
else
$page = 0;
所以，你的要求是一樣的東西：
sprintf($request, "SELECT data FROM pages LIMIT %d, %d", $page, $numRes);
<?php
require_once "connect.php";
define('PER_PAGE',5);
if (isset($_GET['page']) && is_numeric($_GET['page'])): // in your href use "domain.com/index.php?page=1"
$start = $_GET['page_name'] * PER_PAGE;
$query = mysql_query("SELECT username, date FROM users ORDER BY id ASC LIMIT {$start},{$per_page}"); // where to start and for how many 1-5
while ($row = mysql_fetch_array($query)): ?>
<div><h5><?php echo $row['username']; ?> (<?php echo $row['date']; ?>)</h5></div>
<?php
endwhile;
endif;
?>
但我怎麼能改變沒有網址的頁碼 – q7eb2a 2011-03-30 18:20:59
分頁中PHP/MySQL只需使用LIMIT子句即可完成。
最初，您必須計算總記錄數並將其除以每頁記錄數。將頁碼與REQUEST一起傳遞。
從REQUEST數組中讀取頁碼並找出頁面的起始記錄。
您可以進一步閱讀和看到以下頁面http://www.csnotes32.com/2014/11/page-wise-or-paginated-listing-of-data.html
class Pagination
{
public $cur_page;
public $total;
public $per_page;
function __construct($cur_page, $total, $per_page)
{
$this->cur_page = $cur_page;
$this->total = $total;
$this->per_page = $per_page;
}
function getTotalPage(){
return ceil($this->total/$this->per_page);
}
function hasPrevPage(){
if($this->cur_page > 1){
return true;
}
else{
return false;
}
}
function hasNextPage(){
if($this->cur_page < $this->getTotalPage()){
return true;
}
else{
return false;
}
}
function offSet(){
return ($this->cur_page - 1) * $this->per_page;
}
}
$total = 12;
$per_page = 5;
$cur_page = 1;
$pagination = new Pagination($cur_page, $total, $per_page);
$offSet = $pagination->offSet();
$query = "SELECT username, date FROM users ORDER BY id ASC LIMIT {$offset}, {$per_page}";
這是分頁代碼的完整實現。與您的數據庫使用此，您將得到谷歌的風格分頁：
<?php
$conn=mysqli_connect("localhost","root","","ui");
$start=0;
$limit=5;
$t=mysqli_query($conn,"select * from form_table");
$total=mysqli_num_rows($t);
if(isset($_GET['id']))
{
$id=$_GET['id'] ;
$start=($id-1)*$limit;
}
else
{
$id=1;
}
$page=ceil($total/$limit);
$query=mysqli_query($conn,"select * from form_table limit $start,$limit");
?>
