Question

我使用以下代码进行ajax和php的分页。

fetch_pages.php

<?php

include("config.inc.php"); //include config file

//sanitize post value
$page_number = filter_var($_POST["page"], FILTER_SANITIZE_NUMBER_INT, FILTER_FLAG_STRIP_HIGH);

//validate page number is really numaric
if(!is_numeric($page_number)){die('Invalid page number!');}

//get current starting point of records
$position = ($page_number * $item_per_page);

//Limit our results within a specified range. 
//$results = mysqli_query($connecDB,"SELECT id,name,message FROM paginate ORDER BY id ASC LIMIT $position, $item_per_page");
$results=array(array('id'=>1,'name'=>'joe','age'=>'22','job'=>'dev'),array('id'=>2,'name'=>'g','age'=>'21','job'=>'se'),array('id'=>3,'name'=>'gt','age'=>'21','job'=>'se'));
$output = array_slice($results, 0,1); 
//output results from database
echo '<ul class="page_result">';
//while($row = mysqli_fetch_array($results))
foreach ($output as $row) 

{
    echo '<li id="item_'.$row["name"].'">'.$row["age"].'. <span class="page_name">'.$row["job"].'</span><span class="page_message">'.$row["name"].'</span></li>';
}
echo '</ul>';

?>

的index.php

  <?php
include("config.inc.php");

//$results = mysqli_query($connecDB,"SELECT COUNT(*) FROM paginate");
$results=array(array('id'=>1,'name'=>'joe','age'=>'22','job'=>'dev'),array('id'=>2,'name'=>'g','age'=>'21','job'=>'se'),array('id'=>3,'name'=>'gt','age'=>'21','job'=>'se'));
//$get_total_rows = mysqli_fetch_array($results); //total records

//break total records into pages
//$pages = ceil($get_total_rows[0]/$item_per_page); 
$pages = ceil(3/$item_per_page);    

//create pagination
if($pages > 1)
{
    $pagination = '';
    $pagination .= '<ul class="paginate">';
    for($i = 1; $i<$pages; $i++)
    {
        $pagination .= '<li><a href="#" class="paginate_click" id="'.$i.'-page">'.$i.'</a></li>';
    }
    $pagination .= '</ul>';
}

我希望数据源是代码中定义的数组，而不是mysql数据库，因此您将看到$results=array(array('name'=>'gowrie','age'=>'22','job'=>'dev'),array('name'=>'g','age'=>'21','job'=>'se'));而不是mysql查询。

在fetchespages.php中应该有一个查询$results = mysqli_query($connecDB,"SELECT id,name,message FROM paginate ORDER BY id ASC LIMIT $position, $item_per_page");，这会限制页面的结果，但我将其替换为$results=array(array('name'=>'joe','age'=>'22','job'=>'dev'),array('name'=>'g','age'=>'21','job'=>'se'));

页面显示正确的分页链接数，但是当我点击它们时，它们不起作用，它只是继续加载。我不确定我的index.php中的ajax是否存在问题，或者我尝试在fetch_pages.php中限制数组中的结果的方式，即$output = array_slice($results, 0,1);当我点击分页链接时，它在页面上加载相同的东西。

我该如何解决这个问题？

好吧，如果你使用

$ output = array_slice（$ results，0,1）;

无论您点击哪个页面链接，数组始终限于第一个key =＆gt;值对。就像在sql查询中一样，每页使用limit和position / items，你必须对slice函数执行相同的操作。所以它变得像

$output = array_slice($results, $position, $items_per_page);

希望这有帮助
