如何在JSON中获取Wordpress自定义帖子数据? [英] How to get wordpress custom post data in json?
问题描述
在我的模板文件中,我这样获取自定义帖子数据
In my template file i fetch the custom post data like this ,
最初我要获取7个帖子,我需要在该帖子下面添加一个更多的阅读按钮,当有人单击它时,它将从wp数据库表中获取更多7个帖子。
Initially I fetch 7 post, I need to make a read more button bellow the post, which will fetch more 7 posts from the wp database table, when someone click on it.
但是我不知道该怎么做,
But I don't know how to do it, I want to know about,
- 在jquery get方法中,我调用哪个php文件作为数据,
- 我将如何或确切地在该php文件中编写什么脚本。
推荐答案
在这里,我添加了一个粗略的想法,即如何编写代码:
Here i have added a rough idea how you can write your code :
在function.php中创建一个ajax函数,并通过ajax调用将偏移值传递给它,然后将接收到的数据追加到显示部分中。
Create a ajax function in function.php , and pass offset value to it through ajax call and just append the received data in your disply section.
下面是创建ajax函数的示例:
here is an example of creating ajax function :
add_action('wp_ajax_nopriv_cyt_ajax_search','cyt_ajax_search');
add_action('wp_ajax_cyt_ajax_search','cyt_ajax_search');
function cyt_ajax_search(){
$offset = $_POST['offset'];
$args = array (
'post_type' => 'post',
'posts_per_page' =>7
'offset'=>$offset,
'meta_query' =>..........
);
$query = new WP_Query($args);
if($query->have_posts() ) :
while ( $query->have_posts() ) : $query->the_post();
endwhile;
wp_reset_postdata();
endif;
}
//前端代码,单击按钮它将校准ajax函数并传递偏移量值,每次单击时,您都需要将其值增加7(如果您只想加载7个帖子),并检查剩余的帖子数,以及偏移量值是否超过总数计算要通过wp查询显示的数据,然后只需隐藏按钮
//Frontend code , on button click it will cal the ajax function and pass the offset value, on each click you need to increase the value by 7 (in case you want to load 7 post only ) and check how many post are left and if offset value exceedded the no of total counted data to be display by wp query then simply hide the button
<div id ="esiSection"></div>
<span click="loadmore" data-offset='0'>Click here</span>
jQuery('.loadmore').click(function(){
var offset = parseInt(jQuery(this).attr('data-offset'));
jQuery.ajax({
url: '<?php echo admin_url('admin-ajax.php'); ?>',
type: 'POST',
data: {
'action' : 'cyt_ajax_search',
'offset' : offset ,
},
success: function(response) {
jQuery('#resiSection').append(response);
offset = offset + 7;
},
error: function(error){
console.log(error);
}
});
});
