[英]How to pass a php variable to an Wordpress AJAX call?
I have embeded a post (CPT) by a shortode.我通过短篇嵌入了一个帖子(CPT)。 So I get the output of this post on a page, where I want to filter the content of this embeded post by AJAX.
所以我在一个页面上得到这篇文章的输出,我想通过 AJAX 过滤这个嵌入文章的内容。 That would work, if I could send the ID of this embeded post in the ajax call.
如果我可以在 ajax 调用中发送这个嵌入帖子的 ID,那就行了。
I get the ID of the embeded post from a shortcode [documentlist listid="2126"].我从短代码 [documentlist listid="2126"] 中获得了嵌入帖子的 ID。
$atts = shortcode_atts(
array(
'listid' => '',
), $atts
);
$posts = array(
'post_type' => 'documentlist',
'page_id' => $atts['listid'],
);
So I have this $atts['listid'] variable.所以我有这个 $atts['listid'] 变量。 How can I add this to the following ajax code (which is in an diffeent scripts.js file)?
如何将其添加到以下 ajax 代码(位于不同的 scripts.js 文件中)?
/*The ajax call*/
jQuery(function($){
$('#filter #documenttypefilter, #filter #applicationareasfilter').change(function(){
var filter = $('#filter');
var serializedFilter = filter.serialize();
$.ajax({
url:filter.attr('action'),
data:filter.serialize(), // form data
type:filter.attr('method'), // POST
success:function(data){
$('#response').html(data); // insert data
}
});
return false;
});
});
Thanks so much for your help!非常感谢你的帮助!
