我之前收到了一些帮助，以便构建一个Wordpress Ajax加载更多功能，但我正在构建的网站在不同的页面页面上使用不同的差异。
我遇到的问题是从模板文件中控制'post-type' 'postsPerPage'等变量，帮助我的人给了我一个为{{1}创建变量的方法并且在模板，functions.php和JS文件之间传递它完美地工作，我想要做的就是复制'category'和'postsPerPage'，这很容易吗？
显然不是，
我认为我没错，但是functions.php似乎根本没有收到'post-type'变量：
我会将原始代码的原始代码放在其中，然后执行我尝试使其完成的每项更改：
初始模板文件
'postsPerPage'已编辑的模板文件
