如何在WordPress中编辑CSS(编辑、添加和自定义网站的外观)
wp_autosave ( $post_data )
wp_autosave: 这个函数用于在后台保存文章数据: 当用户在编辑一个文章或页面时,它通过AJAX调用,数据被自动保存,而不需要用户点击”保存”按钮。
保存用XHR提交的文章。
旨在与 heartbeat 和 autosave.js 一起使用。
function wp_autosave( $post_data ) { // Back-compat. if ( ! defined( 'DOING_AUTOSAVE' ) ) { define( 'DOING_AUTOSAVE', true ); } $post_id = (int) $post_data['post_id']; $post_data['ID'] = $post_id; $post_data['post_ID'] = $post_id; if ( false === wp_verify_nonce( $post_data['_wpnonce'], 'update-post_' . $post_id ) ) { return new WP_Error( 'invalid_nonce', __( 'Error while saving.' ) ); } $post = get_post( $post_id ); if ( ! current_user_can( 'edit_post', $post->ID ) ) { return new WP_Error( 'edit_posts', __( 'Sorry, you are not allowed to edit this item.' ) ); } if ( 'auto-draft' === $post->post_status ) { $post_data['post_status'] = 'draft'; } if ( 'page' !== $post_data['post_type'] && ! empty( $post_data['catslist'] ) ) { $post_data['post_category'] = explode( ',', $post_data['catslist'] ); } if ( ! wp_check_post_lock( $post->ID ) && get_current_user_id() == $post->post_author && ( 'auto-draft' === $post->post_status || 'draft' === $post->post_status ) ) { // Drafts and auto-drafts are just overwritten by autosave for the same user if the post is not locked. return edit_post( wp_slash( $post_data ) ); } else { // Non-drafts or other users' drafts are not overwritten. // The autosave is stored in a special post revision for each user. return wp_create_post_autosave( wp_slash( $post_data ) ); } }
