问题描述

我有一个使用 2 个 PHP 文件和一个 MySql 数据库的示例页面,我正在尝试在其上使用 jQuery 无限滚动.如何从数据库加载下一组数据?例如,我的图片数据库中有 100 条记录,我想显示 20 条,然后滚动显示下 20 条.

I have a sample page that uses 2 PHP files and a MySql database, and I'm trying to use jQuery infinite scroll on it. How can I load the next group of data from database? For example, I have 100 records in my pictures database, and I want to show 20, and then the next 20 after some scrolling.

这是我目前的核心:

index.php

<?php
ob_start();
require_once('images.html'); 
ob_end_flush();
?>

images.html

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8" />
  <title> trata tata</title>
  <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
  <!--[if lt IE 9]><script src="http://html5shim.googlecode.com/svn/trunk/html5.js"></script><![endif]-->
  <link rel="stylesheet" href="./css/style.css" />
   <!-- scripts at bottom of page -->
</head>
<body class="demos ">
  <nav id="site-nav">
    <h1><a href="./index.html">ole tu jest HOME</a></h1>
    <h2>Menu 1</h2>
    <ul class="docs-list">
        <li><a href="../docs/intro.html">11111111</a>
    </ul>
    <h2>Menu 2</h2>
    <ul class="demos-list">

        <li class="current"><a href="#content">3333333333</a></li>
    </ul>
  </nav> <!-- #site-nav -->

  <section id="content">
     <h1>cos tam ....</h1>
     <div id="container" class="clearfix">
     <?php
     // Make a MySQL Connection
     mysql_connect("localhost", "root", "") or die(mysql_error());
     mysql_select_db("test") or die(mysql_error());

     // Retrieve all the data from the "test " table
     $result = mysql_query("SELECT * FROM foto")
     or die(mysql_error());  

     // store the records of the "TABLENAME" table into $row array and loop through
     while ( $row = mysql_fetch_array( $result, MYSQL_ASSOC ) ) {

     // Print out the contents of the entry 

     //echo "details: ".$row['id'];
     echo '<div class="box photo col3">';
     echo "<img src="".$row['src']."" alt="wwwwww" />";
     echo '</div>';
     }
     ?>
     </div> <!-- #container -->

           });
         });

推荐答案

您需要将 LIMIT 添加到您的查询中.MySQL 手册中的示例:

SELECT * FROM tbl LIMIT 5,10; # Retrieve rows 6-15

Here, 5 is the starting offset, and 10 is the amount of rows you want to fetch.

这里,5 是起始偏移量,10 是您要获取的行数.

For the client-side you'll need the infinite scroll jQuery plugin.
