Question

如何在此代码中实现分页：

<?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; ?>

Answer 1

想法是使用mysql LIMIT关键字。它允许您限制从mysql获得的结果数。

SELECT data FROM table LIMIT 5

相当于

SELECT data FROM table LIMIT 0, 5

其中0是偏移量，5是MySQL返回的行数。

所以你必须修改一些要显示的项目，让我们说$numRes = 10和一个页码：

if (isset($_GET['page']) && is_numeric($_GET['page']))
     $page = $_GET['page'];
else
     $page = 0;

所以你要求的是：

sprintf($request, "SELECT data FROM pages LIMIT %d, %d", $page, $numRes);

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}";

Answer 3

<?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;
?>

使用LIMIT子句可以简单地实现PHP / MySQL中的分页。

最初，您必须计算总记录数并将其除以每页的记录数。将页码与REQUEST一起传递。

从REQUEST数组中读取页码，找出页面的起始记录。

这是分页代码。将其与您的数据库一起使用，您将获得Google样式分页：

 <?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");
     ?>
