使用php和mysql進行Ajax分頁

Question

我正在嘗試使用Ajax在我的網站上設置分頁，我已經在以下鏈接繼承了一個腳本並將其付諸實踐 - http://www.testing.arrivaldesign.co.uk/properties。

我已經在一定程度上工作了，但它設置爲顯示前9條記錄，然後從那裏繼續，但它只顯示第一頁上的前9個，但當您點擊下一個時頁面只重複4個現有記錄。

據我所見，這是與我的查詢限制，但我不知道如何得到它的工作？

這是事物的ajax方面的代碼。

<?php 
include('Connections/connection.php'); 

include 'functions.php'; 

// Pagination params 
$basePath  = 'http://' . $_SERVER['SERVER_NAME'] . $_SERVER['PHP_SELF']; 
$qString  = $_REQUEST['qString']; 
$items   = $_REQUEST['items']; 
$loadPage  = $_REQUEST['p']; 
$current  = $_REQUEST['current']; 

$limit = $loadPage*$items; 
$min = ($max-$items)+1; 

mysql_select_db($database, $conn); 
$query_RSproperty = "SELECT properties.*, type.* FROM (properties LEFT JOIN type ON properties.propType=type.typeID) WHERE offline = 'N' ORDER BY propID ASC LIMIT 0, $limit"; 
$RSproperty = mysql_query($query_RSproperty, $conn) or die(mysql_error()); 
$row_RSproperty = mysql_fetch_assoc($RSproperty); 
$totalRows_RSproperty = mysql_num_rows($RSproperty); 

$maxItems  = $totalRows_RSproperty; 

// New pagination 
$pagination = paginator($basePath . $qString, $loadPage, $maxItems, $items); 

// Direction is important for the script to determine which way to animate, left or right. 
$direction = 'left'; 
if ($current < $loadPage) { 
    $direction = 'right'; 
} 
$paginatedStyle = 'style="left:'.($direction == 'left' ? '0' : '-960px').';"'; 


// The paginated content HTML slide 
$page = '<div class="paginated" id="" '.$paginatedStyle.'>';

那是因爲你已經很難在查詢編碼限制爲0

$query_RSproperty = "SELECT properties.*, type.* FROM (properties LEFT JOIN type ON properties.propType=type.typeID) WHERE offline = 'N' ORDER BY propID ASC LIMIT 0, $limit"; 

所以，當你在第二頁上移動時，查詢必須得到生成如下

$query_RSproperty = "SELECT properties.*, type.* FROM (properties LEFT JOIN type ON properties.propType=type.typeID) WHERE offline = 'N' ORDER BY propID ASC LIMIT 0, 4"; 

因此你得到第4條記錄。如果您要檢索的下一組的後續網頁上的記錄，那麼你必須做出0 LIMIT 0, $limit動態，如：

$query_RSproperty = "SELECT properties.*, type.* FROM (properties LEFT JOIN type ON properties.propType=type.typeID) WHERE offline = 'N' ORDER BY propID ASC LIMIT $offset, $limit"; 

你算算$偏移取決於你有多少結果每頁顯示。在第一頁上，偏移量始終爲0.如果每頁顯示10條記錄，則在第二頁上，偏移量將爲11，第三個偏移量爲21，依此類推。
