Question

我正在使用无限的ajax滚动。正确获取数据库中的值。但是当我向下滚动时，会显示从0到10的相同结果。我不知道我犯了什么错误。

查询以this link打印。如何通过递增下10个结果来使查询动态化？目前，滚动时会显示相同的结果。

<?php include_once('../inc/header.php')?>

<?php

$page = (int) (!isset($_GET['p'])) ? 1 : $_GET['p'];
echo $page;
# find out query stat point
$start = (($page * $limit) - $limit);

# sql query
$SQL = sprintf("SELECT SQL_CALC_FOUND_ROWS * FROM review_news WHERE category='%s' ORDER BY id DESC LIMIT %d, %d", 
mysql_real_escape_string($category), 0, 10);

print $SQL;
# query for dataset
$ResDataSet  = mysql_query($SQL) or die(mysql_error());

# query for page navigation
$ResFoundRow = mysql_query("SELECT FOUND_ROWS() AS NumRow") or die( mysql_error() );
$RowFoundRow = mysql_fetch_array($ResFoundRow);


if ( $RowFoundRow['NumRow'] <= 0) 
{

    echo 'Page not found!';
    exit();
} else if( $RowFoundRow['NumRow'] > ($page * $limit) ) {


   $next = ++$page;
}

Answer 1

mysql_real_escape_string($category), 0, 10);是你的问题。

将其更改为;

mysql_real_escape_string($category), $start, 10);

Answer 2

您需要设置$limit以正确计算$start，然后在查询中使用$start和$limit

$limit = 10;
$page = (int) (!isset($_GET['p'])) ? 1 : $_GET['p'];
echo $page;
# find out query stat point
$start = (($page * $limit) - $limit);

# sql query
$SQL = sprintf("SELECT SQL_CALC_FOUND_ROWS * FROM review_news WHERE category='%s' ORDER BY id DESC LIMIT %d, %d", 
mysql_real_escape_string($category), $start, $limit);

无限的ajax滚动，php和jquery
