将PHP变量传递到AJAX加载的页面

Question

I have a blog that shows 9 blogs posts per page, with each additional page of blog posts automatically added using the Infinite Ajax Scroll plugin. 我有一个博客，每页显示9博客文章，并使用Infinite Ajax Scroll插件自动添加博客文章的每个其他页面。

Every time a blog post is successfully queried the $postCount variable increases its count by 1 . 每次成功查询博客帖子时， $postCount变量$postCount其计数增加1 。

[...]
<body>

    <div class="posts">
        <?php
        $postCount = 0;
        if ( have_posts() ) : while ( have_posts() ) : the_post(); $postCount++;
            if ( $postCount % 9 == 0 ) :
                // show featured blog posts
            else :
                // show standard blog posts
            endif;
        endif;
        ?>
    </div> <!-- /posts -->

    <script>
        var ias = jQuery.ias({
            container:       '.posts',
            item:            'article',
            pagination:      '.pagination',
            next:            '.next',
            delay:           0,
            negativeMargin:  1000
        });
    </script>

</body>

I'd like for the $postCount variable to remember its count on the AJAX loaded pages as well. 我想让$postCount变量也记住它在AJAX加载页面上的计数。 So, instead of resetting to 0 the next page of blog posts would start at 10 . 因此，与其重置为0 ，下一页博客文章将从10开始。

I understand why it's not working (variables are only local) and that I'll need to use something like sessions or get , but I don't know how to implement that. 我了解为什么它不起作用（变量仅在本地），并且我需要使用诸如sessions或get类的东西，但我不知道如何实现。

I'm guessing I need to start a session on my index.php page pass that along to my IAS plugin call... 我猜我需要在index.php页面上开始一个session ，并将其传递给我的IAS插件调用...

Any help greatly appreciated. 任何帮助，不胜感激。 Thanks! 谢谢！

I've had some luck getting PHP sessions to work by starting the session in my functions.php file 我很幸运，可以通过在我的functions.php文件中启动会话来使PHP会话正常工作

function init_session() {
    session_start();
}
add_action( 'init', 'init_session', 1 );

...and adding the sessions to my file like so: ...然后将会话添加到我的文件中，如下所示：

[...]
<body> 

   <div class="posts">
        <?php

        $postCount = 0;

        if ( isset ( $_SESSION[ 'postCount' ] ) ) :
            $postCount = $_SESSION[ 'postCount' ];
        endif;

        [...] // wp_query

        $_SESSION['postCount'] = $postCount;

        ?>
    </div> <!-- /posts -->

</body>

As it stands the $postCounter keeps counting... So what was initially considered post 1 could be post 100 when the page is refreshed. 就目前而言， $postCounter一直在计数...因此，最初认为发布1可能是刷新页面时发布的100 。

I'll need to workout the logic to destroy the session if it's the first post... 如果这是第一篇文章，我需要锻炼逻辑以销毁会话。

Any thoughts welcome. 任何想法欢迎。 Thanks. 谢谢。

I was able to keep the $postCount variable counting by starting a php session in my functions.php file 通过在我的functions.php文件中启动php会话，我能够保持$postCount变量计数

function init_session() {
    session_start();
}
add_action( 'init', 'init_session', 1 );

...and setting up my loop like so: ...并像这样设置我的循环：

[...]
<body> 

   <div class="posts">
        <?php

        $postCount = 0;

        if ( is_paged() ) :
            $postCount = $_SESSION[ 'postCount' ];
        endif;

        [...] // wp_query

        $_SESSION['postCount'] = $postCount;

        ?>
    </div> <!-- /posts -->

</body>

Using is_paged() is the key to keep the counter at 0 after a refresh. 使用is_paged()是刷新后将计数器保持为0的关键。
