我用Ajax调用页面，我在functions.php 要确定调用哪个页面，然后呈现相应的模板：

function ajax_callback() {
    if( isset(  $_POST[\'href\'] ) ) {
        $pageId = preg_match( \'/^http:\\/\\/.+\\/\\?page_id=\\d+$/\', $_POST[\'href\'] ) ? substr( strrchr( $_POST[\'href\'], \'=\' ), 1 ) : \'8\' ;

        if( $pageId === \'8\' ) get_template_part(\'home-ajax\');
        elseif( $pageId === \'22\' ) get_template_part(\'reviews-rvw-ajax\');
        elseif( $pageId === \'6\' ) get_template_part(\'noticias-news-ajax\');
        elseif( $pageId === \'109\' ) get_template_part(\'entrevistas-ajax\');
    }
}

这很好，但现在我也想打单发。我的帖子类型如下：

$pageId = preg_match( \'/^http:\\/\\/.+\\/\\?page_id=\\d+$/\', $_POST[\'href\'] ) ? substr( strrchr( $_POST[\'href\'], \'=\' ), 1 ) : \'no-page\' ;
if( $pageId === \'no-page\' && preg_match( \'/^http:\\/\\/.+\\/\\?news=.+$/\', $_POST[\'href\'] ) ) {
        $newSlug = substr( strrchr( $_POST[\'href\'], \'=\' ), 1 );
} elseif ( $pageId === \'no-page\' && preg_match( \'/^http:\\/\\/.+\\/\\?reviews=.+$/\', $_POST[\'href\'] ) ) {
    $reviewSlug = substr( strrchr( $_POST[\'href\'], \'=\' ), 1 );
}

if( $pageId !== 0 ) {
    if( $pageId === \'8\' ) get_template_part(\'home-ajax\');
    elseif( $pageId === \'22\' ) get_template_part(\'reviews-rvw-ajax\');
    elseif( $pageId === \'6\' ) get_template_part(\'noticias-news-ajax\');
    elseif( $pageId === \'109\' ) get_template_part(\'entrevistas-ajax\');
} elseif( $newSlug !== \'\' ) {
            //here I have to get the single post template
            // e.g. $newSlug = slug-post-name, and post_type = \'news\'
}

但我不知道如何用slug的名字来命名这个单一的帖子模板。我得打电话给single.php 没有页眉和页脚的模板，因此我可以执行以下操作：

get_template_part(\'single-ajax\');

//single-ajax.php
<?php
            // Start the Loop.
            while ( have_posts() ) : the_post();

                /*
                 * Include the post format-specific template for the content. If you want to
                 * use this in a child theme, then include a file called called content-___.php
                 * (where ___ is the post format) and that will be used instead.
                 */
                get_template_part( \'content\', get_post_format() );

                // Previous/next post navigation.
                twentyfourteen_post_nav();

                // If comments are open or we have at least one comment, load up the comment template.
                if ( comments_open() || get_comments_number() ) {
                    comments_template();
                }
            endwhile;

但不起作用，因为我应该定义查询对象：

        <?php
 $temp = $wp_query; // assign ordinal query to temp variable for later use  
 $wp_query = null;
 $newSlug = substr( strrchr( $_POST[\'href\'], \'=\' ), 1 );
 $wp_query = new WP_Query( array( \'name\' => $newSlug  ) ); 
 if($wp_query->have_posts()) {
while ( $wp_query->have_posts() ) : $wp_query->the_post();
    // Start the Loop.
        /*
         * Include the post format-specific template for the content. If you want to
         * use this in a child theme, then include a file called called content-___.php
         * (where ___ is the post format) and that will be used instead.
         */
        get_template_part( \'content\', get_post_format() );

        // Previous/next post navigation.
        twentyfourteen_post_nav();

        // If comments are open or we have at least one comment, load up the comment template.
        if ( comments_open() || get_comments_number() ) {
            comments_template();
        }
endwhile;
}
die();

但这不会显示帖子模板。实际上，不会开始执行循环。你知道发生了什么事，或者有什么更简单的方法来实现这一点吗？

$args = array (
 \'post_type\' => $post_type,
 \'post_status\' => \'publish\',
 \'name\'=> $newSlug
);
 $wp_query = new WP_Query( $args );
