jQuery Infinity滚动使用Mysql / PHP反复循环

Question

I'm trying to implement Jquery infinity scroll found at ( http://infiniteajaxscroll.com/ ) together with my MYSQL and PHP. And it works, sort of.

I found similar example here but my was quite different anyway ( http://www.w3bees.com/2013/09/jquery-infinite-scroll-with-php-mysql.html )

The loading more works fine however my results are being looped over and over again. I mean i display all the results in the first page and when i scroll down at the bottom and infinity scroll fires up then same results are being showed instead of splitting those first results in different pages.

Here is my code, quite long :)

<?php


$page = (int) (!isset($_GET['s'])) ? 1 : $_GET['s'];


// GET ALL THE SHOUTBOX
$sql = "SELECT * FROM shoutbox
ORDER BY id DESC
LIMIT 20";

//prepare the statement
$statement = $dbConn->prepare($sql);

//execute the statement
$statement->execute();

//Count the shouboxes         
$number_of_shoutbox = $statement->rowCount();

$number_of_posts_per_page = '10';

$total_pages = $number_of_shoutbox / $number_of_posts_per_page;


?>

======================================================================== UPDATE CODE BY STILL GIVING ERRORS NOW IN MYSQL:

Tried @Rob Schmuecker solution but now getting errors in mysql.

Here is my modified code with PDO and with Rob Schmuecker suggestion

// GET ALL THE SHOUTBOX
$sql = "SELECT
shoutbox.shoutbox_id,
shoutbox.text,  
shoutbox.date,
shoutbox.time,
shoutbox.approved,
shoutbox.`new`, 
shoutbox.user_id, 
users.profile_image,
users.user_name,
users.user_age,
users.country,
users.gender_search,
users.age_from,
users.age_to
FROM    shoutbox INNER JOIN users ON shoutbox.user_ID = users.id
WHERE   users.profile_image = '2'
AND     shoutbox.approved = '1'
AND     shoutbox.new = '0'
AND     shoutbox.user_id != :admin_id
AND (shoutbox.user_id NOT IN (SELECT user_id FROM users_blocked WHERE blocked_id = :user_id))  
ORDER BY shoutbox.shoutbox_id DESC
LIMIT :limit_start :limit_row_amount";

//prepare the statement
$statement = $dbConn->prepare($sql);

//execute the statement
$statement->execute(array(
            'admin_id' => $admin_id,
            'user_id' => $user_id,
            'limit_start' => $limit_start,
            'limit_row_amount' =>$limit_row_amount


        ));

Answer 1

You need to implement the page into your SQL query.

Below we define two new variables, one which is the total amount you want to retrieve each time and the next is the amount of rows to skip in each limit query, starting from 0 if $page = 1

$page = (int) (!isset($_GET['s'])) ? 1 : $_GET['s'];

$limit_row_amount = 20;
if($page > 1){
    $limit_start = $page * $limit_row_amount;
} else {
    $limit_start = 0;
}

// GET ALL THE SHOUTBOX
$sql = "SELECT * FROM shoutbox
ORDER BY id DESC
LIMIT $limit_start, $limit_row_amount";
