在unctions.php中使用条件语句

我在下面的functions.php 我想用条件语句添加两个过滤器，以避免影响每个query\\u帖子。像这样的

if(!is_admin() && is_page(\'Home\')){ //two filters }

然而，我对PHP的了解还不够，不知道把它放在哪里或如何使用<?php> 标签。有人能提供建议吗？它来自this thread 这是在WP论坛上关闭的。

add_filter(\'posts_orderby\', \'edit_posts_orderby\');
add_filter(\'posts_join_paged\',\'edit_posts_join_paged\');

function edit_posts_join_paged($join_paged_statement) {
    global $wpdb;
    $join_paged_statement = "LEFT JOIN ".$wpdb->prefix."wpv_voting ON ".$wpdb->prefix."wpv_voting.post_id = $wpdb->posts.ID";
    return $join_paged_statement;
}

function edit_posts_orderby($orderby_statement) {
    global $wpdb;
    $orderby_statement = "(".$wpdb->prefix."wpv_voting.vote_count) DESC";
    return $orderby_statement;
}

add_action( \'pre_get_posts\', \'wpse_71899_start_filter\' ); function wpse_71899_start_filter() { // wrong page if ( ! is_page( \'Home\' ) ) return; // stop here. add_filter(\'posts_orderby\', \'edit_posts_orderby\'); add_filter(\'posts_join_paged\',\'edit_posts_join_paged\'); } function edit_posts_join_paged($join_paged_statement) { global $wpdb; $join_paged_statement = "LEFT JOIN ".$wpdb->prefix."wpv_voting ON ".$wpdb->prefix."wpv_voting.post_id = $wpdb->posts.ID"; return $join_paged_statement; } function edit_posts_orderby($orderby_statement) { global $wpdb; $orderby_statement = "(".$wpdb->prefix."wpv_voting.vote_count) DESC"; return $orderby_statement; }

Ajax, filters and shortcodes

您能理解为什么我无法在ajax帖子包含中应用短代码过滤器吗？让我更好地解释一下：我已经设法在另一篇文章中包含一篇文章，通过admin-ajax.php, 正如著名的5 tips.很明显，我不想显示快捷码标签，也不想去掉它们，所以我在回应do_shortcode($post->post_content)此时，虽然我正在运行“Cleaner gallery”插件，但post gallery会被渲染，但未被过滤add_filter( \'post_gallery\', \'cleaner_gallery\
