设置带有GET POST错误的瞬变

我有一个大的WordPress安装超过200000篇文章，具有自动发布文章的功能。我的帖子内容包含“一些HTML标签，一些文本，一些<img> 标签“。我需要删除所有<img> 标记来自特定帖子的帖子内容。所以我有这个功能来完成这项工作：

function remove_images_form_past_posts() {
    if ( get_transient(\'images_removed_from_past\') )
        return;
    $args = array( 
                \'post_type\' => \'post\', 
                \'year\' => 2013, 
                \'monthnum\' => 1, 
                \'day\' =>28,     
                \'post_status\' =>\'publish\',
                \'category\' => 30,
                \'post_author\' => 3,
                \'nopaging\' => 1
            );
    $posts = get_posts( $args );    
        if ( $posts ) {
            foreach ( $posts as $post ); setup_postdata( $post ); {
                $newcontent = preg_replace(\'/<img[^>]+\\>/i\', \'\', $post->post_content);
                $newpost = array(
                               \'ID\' => $post->ID, 
                               \'post_content\' => $newcontent
                           );
                wp_update_post($newpost);
                wp_reset_postdata();
            }
            set_transient(\'images_removed_from_past\', 60 * 60 * 24);
        }
    }
add_action(\'admin_init\',\'remove_images_form_past_posts\');

以上代码是完美的&；做这项工作，但有一个问题：不幸的是，这段代码只更新了1篇文章，尽管$args 匹配9个帖子。

我已经测试了get_posts 单独（&A）；它工作得很好&；执行9个员额。我已经阻止了WP_super_cache 插件（&A）；也没办法。我试图将“set\\u transient$value”从1更改为9，但没有办法。

任何想法！

<?php function remove_images_form_past_posts() { if ( get_transient(\'images_removed_from_past\') ) return; $args = array( \'post_type\' => \'post\', \'year\' => 2013, \'monthnum\' => 1, \'day\' =>28, \'post_status\' =>\'publish\', \'category\' => 30, \'post_author\' => 3, \'nopaging\' => 1 ); $posts = get_posts( $args ); if ( $posts ) { foreach ( $posts as $post ) { $newcontent = preg_replace(\'/<img[^>]+\\>/i\', \'\', $post->post_content); $newpost = array( \'ID\' => $post->ID, \'post_content\' => $newcontent ); wp_update_post($newpost); } set_transient(\'images_removed_from_past\',true, 60 * 60 * 24); } } add_action(\'admin_init\',\'remove_images_form_past_posts\');

foreach ( $posts as $post ) { //remove the »;« setup_postdata( $post ); //move this inside the loop $newcontent = preg_replace(\'#(<[/]?img.*>)#U\', \'\', $post->post_content); $newpost = array( \'ID\' => $post->ID, \'post_content\' => $newcontent ); wp_update_post($newpost); } wp_reset_postdata(); //do not forget to reset postdata after the loop

//make your parameters variables $ay = \'2013\'; //year $am = \'1\'; //month $ad = \'28\'; //day $ac = \'30\'; //category $aa = \'3\'; //author //get your transient based on the set of variables if (get_transient(\'rm_img_\'.$ay.\'_\'.$am.\'_\'.$ad.\'_\'.$ac.\'_\'.$aa.\'\') ) return; //use the variables in your args $args = array( \'post_type\' => \'post\', \'year\' => $ay, \'monthnum\' => $am, \'day\' => $ad, \'post_status\' =>\'publish\', \'category\' => $ac, \'post_author\' => $aa, \'nopaging\' => 1 ); //get your transient based on the set of variables set_transient(\'rm_img_\'.$ay.\'_\'.$am.\'_\'.$ad.\'_\'.$ac.\'_\'.$aa.\'\', true, 0);

Transients API and multisite

我们正在使用Atlas HTML站点地图插件，该插件使用transients API缓存站点地图，调用如下：set_transient( \'dmac_html_sitemap\', $output, 60*60*24*7 ); 现在，我们还有一个多站点设置，我想知道瞬态存储在哪里，WP multisite是否将它们分开。它将选项分开，因为每个站点（博客）都有自己的DB表前缀（例如wp\\U 29\\U选项）。我在某个地方读到，瞬态可以用memcached存储，所以我猜后端存储是可插入的。这个问
