Question

我正在制作一个页面，其中将有表格（每个表格位于字段集中），并且可以选择编辑或删除记录。我添加了分页，因为表格对于页面来说太大了。当我转到下一页时，唯一的问题是（我是初学者），所有的表都转到下一页。是否可以按字段集进行分页工作？

这就是我到目前为止:(其巨大的代码，我只放了一张表的一部分）

指数：

<?php

    include("pagination2.php"); 


?>

     <div id="pagination">
     <div id="pagiCount">


<html> 
<head>
<nav>
    <ul>
    <li><a href="Index.php">Home</a>
    <li><a href="Inventory.php">Inventory</a>
    <li><a href="Categories.php">Categories</a>
    <li><a href="Sales.php">Sales</a>
    <li><a href="Customers.php">Customers</a></a>
    <li><a href="Reports.php">Reports</a>
    <li><a href="#top">Edit</a></a>
    <li><a href="Remove.php">Remove</a></a>

    </ul>
</nav>

</br></br></br></br>

  <link rel="stylesheet" href="Styles.css">

<fieldset>
<?php
        include_once('Connect2db.php');
        if(isset($_POST['Categorie1'])) {
        $Categorie = $_POST['Categorie1'];

        if(mysql_query("INSERT INTO bcd VALUES('','$Categorie1')"))
        echo "successful!";
        else
        echo "Please try again";
        } 

        $res = mysql_query("SELECT * FROM bcd");

?>


<h1> Lijst met Categories..</h1>

<?php
        while( $row = mysql_fetch_array($res) )
        echo "$row[ID]. $row[Categorie1] <a href='Edit.php?edit=$row[ID]'>edit</a><br />";
?>

 <?php
                if(isset($pages))
                {  
                    if($pages > 1)        
                    {    if($cur_page > $num_links)     ///////////to take to page 1 //////////
                        {   $dir = "first";
                            echo '<span id="prev"> <a href="'.$_SERVER['PHP_SELF'].'?page='.(1).'">'.$dir.'</a> </span>';

                        }

                        }

                }
    ?>
        </div>
    </div>
</fieldset>
<fieldset>

分页：

<?php


$con = mysql_connect("localhost","root","");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }
  // select database
  mysql_select_db("inventarisdb", $con); ////provide database name

 $query = mysql_query("SELECT * FROM bcd");
 $total_rows = mysql_num_rows($query);

 $base_url = 'https://localhost/pagi/';
  $per_page = 7;                           //number of results to shown per page 
  $num_links = 8;                           // how many links you want to show
  $total_rows = $total_rows; 
  $cur_page = 1;                           // set default current page to 1

if(isset($_GET['page']))
    {
      $cur_page = $_GET['page'];
      $cur_page = ($cur_page < 1)? 1 : $cur_page;            //if page no. in url is less then 1 or -ve
    }

  $offset = ($cur_page-1)*$per_page;                //setting offset

  $pages = ceil($total_rows/$per_page);              // no of page to be created    

 $start = (($cur_page - $num_links) > 0) ? ($cur_page - ($num_links - 1)) : 1;
    $end   = (($cur_page + $num_links) < $pages) ? ($cur_page + $num_links) : $pages;

 $res = mysql_query("SELECT * FROM bcd LIMIT ".$per_page." OFFSET ".$offset);

 mysql_close($con);
 ?>

请告诉我每个字段集的分页是否可行，以及我尝试实现此目的的方法是否合适。我们也欢迎使用教程或示例链接来实现我想要的。先谢谢你了！

每个字段集的分页是否可能？
