PHP/MySQL通过加载更多按钮将数据从一个表块复制到另一个表

我希望这将对您有所帮助。您可以在php中实现它以加载更多操作。

每次点击更多按钮后在mysql查询中更改偏移量和限制

INSERT INTO table2 SELECT * FROM table1 LIMIT 0, 25;
load more...
INSERT INTO table2 SELECT * FROM table1 LIMIT 25, 25;
load more...
INSERT INTO table2 SELECT * FROM table1 LIMIT 50, 25;

Commplete代码。

1.只需在page1.php 中复制并粘贴以下代码

<div id='message'></div>
<a href='#' id='LoadMore' >Load More</a>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"
    type="text/javascript"></script>
<script>
$(function() {
    var page = 1;
    $("#LoadMore").click(function(){
        $.ajax({
            type:"GET",
            url:"page2.php",
            data:{page:page},
            success: function(response) {
                $("#message").append(response); 
                page++;
            }
        });
    }); 
});
</script>

2.在page2.php 中复制以下代码

并更改前两行中的mysql_server、mysql_user、mysql_password、database_name参数

<?php
//set argument as your mysql server
$connect = mysql_connect("mysql_server","mysql_user","mysql_password");
mysql_select_db("database_name",$connect);
$page = isset($_GET["page"]) ? $_GET["page"] : 1;
$limit = 25;
$offset = ($page - 1) * $limit;
$sql = "INSERT INTO table2 SELECT * FROM table1 limit $offset, $limit";
mysql_query($sql);
$rows = mysql_affected_rows();
echo "$rows rows added to table2 from table1<br>";
?>

3.在浏览器中运行page1.php。。。并将数据加载到表2

现在显示表2中的数据，而不按要求刷新页面（user2714387在评论中表示）

4.在page3.php 中复制并粘贴以下代码

<table width="300" border="1" id='data_grid'></table>
<a href='javascript://' id='LoadMore' >Load More</a>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"
    type="text/javascript"></script>
<script>
$(function() {
    var page = 1;
    $("#LoadMore").click(function(){
        $.ajax({
            type:"GET",
            url:"page4.php",
            data:{page:page},
            success: function(response) {
                $("#data_grid").append(response); 
                page++;
            }
        });
    }); 
});
</script>

4.在page4.php 中复制以下代码

<?php
    //set argument as your mysql server
    $connect = mysql_connect("mysql_server","mysql_user","mysql_password");
    mysql_select_db("database_name",$connect);
    $page = isset($_GET["page"]) ? $_GET["page"] : 1;
    $limit = 25;
    $offset = ($page - 1) * $limit;
    $sql = "SELECT * FROM table2 limit $offset, $limit";
    $result = mysql_query($sql);
    $numRows = mysql_num_rows($result);
    if($numRows>0) {
        while($row = mysql_fetch_array($result)) {
            //get field data and set to the following row
            echo "<tr><td>field 1</td><td>field 2</td><td>field 3</td></tr>";
                    //edit row as you table data
        }
    } else {
        echo "<tr><td colspan='3'> No more data </td></tr>";
    }
    exit;
?>

6.在浏览器中运行page4.php
