我真的很难找到一种方法来为我的Wordpress帖子创建ajax分页。我找到的解决方案不起作用。
在这里提供更多信息是一个链接,底部有子弹用于分页。点击这些后,我希望网站的效果加载新帖子而不触发页面刷新。 http://maxlynn.co.uk/natural-interaction/category/all/
我的问题是,是否有任何好的教程,你可能已经取得了这种效果的成功。
如果您需要更多信息,请与我们联系。

function kriesi_pagination($pages = '', $range = 2) {
$showitems = ($range * 2)+1;
global $paged;
if (empty($paged)) $paged = 1;
if ($pages == '') {
global $wp_query;
$pages = $wp_query->max_num_pages;
if (!$pages) {
$pages = 1;
}
}
if (1 != $pages) {
echo "<div class='pagination'><div class='pagination-container'>";
if($paged > 2 && $paged > $range+1 && $showitems < $pages) echo "<a href='".get_pagenum_link(1)."'>«</a>";
if($paged > 1 && $showitems < $pages) echo "<a href='".get_pagenum_link($paged - 1)."'>‹</a>";
for ($i=1; $i <= $pages; $i++) {
if (1 != $pages &&( !($i >= $paged+$range+1 || $i <= $paged-$range-1) || $pages <= $showitems ))
{
echo ($paged == $i)? "<span class='current'>".$i."</span>":"<a href='".get_pagenum_link($i)."' class='inactive' >".$i."</a>";
}
}
if ($paged < $pages && $showitems < $pages) echo "<a href='".get_pagenum_link($paged + 1)."'>›</a>";
if ($paged < $pages-1 && $paged+$range-1 < $pages && $showitems < $pages) echo "<a href='".get_pagenum_link($pages)."'>»</a>";
echo "</div>\n</div>\n";
}
}
这是我正在使用的PHP,如何使用此php创建ajax请求,以便页面不会重新加载?
答案 0 :(得分:2)
您需要做的是防止分页链接上的默认值,并发送AJAX请求以获取帖子。 Wordpress以这种方式为AJAX工作:您使用wp-admin/admin-ajax.php
参数将所有请求发送到action
,该参数将识别请求,以便使用{在 functions.php 中捕获它{1}}和wp_ajax_nopriv_my_action
挂钩。
所以基本上你会在模板文件中执行此操作:
wp_ajax_my_action
您必须根据模板更改班级名称/属性等。
在 functions.php 方面:
<script type="text/javascript">
jQuery(document).ready(function($) {
$('.pagination a').click(function(e) {
e.preventDefault(); // don't trigger page reload
if($(this).hasClass('active')) {
return; // don't do anything if click on current page
}
$.post(
'<?php echo admin_url('admin-ajax.php'); ?>', // get admin-ajax.php url
{
action: 'ajax_pagination',
page: parseInt($(this).attr('data-page')), // get page number for "data-page" attribute
posts_per_page: <?php echo get_option('posts_per_page'); ?>
},
function(data) {
$('#content-posts').html(data); // replace posts with new one
}
});
});
});
</script>
问题是查询所请求页面的帖子(因此我们计算页码和每页帖子选项的偏移量),并使用您用于单个帖子的模板显示它们。
您也可能想要操纵浏览器历史记录,因此您应该查看the History API。
