Question

我在WordPress中使用了多个自定义帖子类型。每个用户都可以将公司资料添加为名为“公司”的特定邮政类型。如果用户拥有公司资料，他可以添加更多内容，如工作，活动等。全部定义为特定的自定义帖子类型。

用户也可能删除自己的公司资料。如果他这样做，那么用户的所有其他帖子也应该被删除（正常帖子除外），并且URL应该被重定向（301）到主页。

我在WP文档（https://codex.wordpress.org/Plugin_API/Action_Reference/delete_post）中找到了“delete_post”操作。但我不确定如何解雇它。

有人有提示吗？

Answer 1

我找到了解决方案。问题是行动＆＃39; delete_post＆＃39;。我已将其更改为＆＃39; trash_to_publish＆＃39;基于帖子状态转换：https://codex.wordpress.org/Post_Status_Transitions

现在一切正常。

/**
 * Deletes all posts from author of company profile.
 */
function delete_all_posts_from_author($post_id) {


    global $post;
    $id = $post->ID;

    // Only trigger if post type is "company"
    if ( get_post_type($id) == "company" ) {

        $author_id = $post->post_author;

        $posts_from_author = get_posts(
            array(
                'posts_per_page'    => -1,
                'post_status'       => 'publish',
                'post_type'         => array('event','job'),
                'author'            => $author_id,
                'fields'            => 'ids', // Only get post ID's
            )
        );

        foreach ( $posts_from_author as $post_from_author ) {
            wp_trash_post( $post_from_author, false); // Set to False if you want to send them to Trash.
        }
    }


}

add_action( 'publish_to_trash',  'delete_all_posts_from_author', 10, 1 );

作为奖励我可以使用该功能再次发布用户的所有帖子，如果我解开公司资料。

/**
 * Untrash posts if company profile is untrashed
 */
function untrash_all_posts_from_author($post_id) {


    global $post;
    $id = $post->ID;

    if ( get_post_type($id) == "company" ) {

        $author_id = $post->post_author;

        $posts_from_author = get_posts(
            array(
                'posts_per_page'    => -1,
                'post_status'       => 'trash',
                'post_type'         => array('event','job'),
                'author'            => $author_id,
                'fields'            => 'ids', // Only get post ID's
            )
        );

        foreach ( $posts_from_author as $post_from_author ) {
            wp_untrash_post( $post_from_author); // Set to False if you want to send them to Trash.
        }
    }


}

add_action( 'trash_to_publish',  'untrash_all_posts_from_author', 10, 1 );

希望有所帮助。如果我犯了错误，请告诉我。

编辑：我已将参数wp_delete_post()更改为wp_trash_post()，因为wp_delete_post()仅适用于本机帖子，网页和附件。 @rarst在这里给出了很好的答案：https://wordpress.stackexchange.com/questions/281877/error-after-deleting-custom-post-type-with-a-function-no-trash-used/281888#281888

Answer 2

类似的东西：

// Add action trigger
add_action( 'delete_post', 'delete_other_custom_posts', 10 );

function delete_other_custom_posts( $post_id ) {
    global $wpdb;
    $post = get_post( $post_id );

    // Only trigger if post type is "company"
    if ( $post->post_type == "company" ) {
        $author_id = $post->post_author;

        // Find other custom posts' ids by the same user
        $posts_to_delete = $wpdb->get_col(
            $wpdb->prepare(
                "SELECT ID FROM {$wpdb->prefix}posts WHERE post_status = 'publish' AND post_author = %d AND post_type IN (<put your custom post types' slugs here>)",
                $author_id
            ), ARRAY_A
        );

        if ( $posts_to_delete ) {
            foreach ( $posts_to_delete as $post_delete_id ) {
                // Delete the custom post
                wp_delete_post( $post_delete_id );
            }
        }

        // Redirect
        wp_redirect(<page you want to redirect to>);
        exit;
    }
}

Answer 3

这是可能的。公司是邮政类型所以剩余的内容将是分类，所以当你删除帖子那里元，分类法将不会被删除。

<?php
add_action( 'admin_init', 'codex_init' );
function codex_init() {
    add_action( 'delete_post', 'codex_sync', 10 );
}

function codex_sync( $pid ) {
    global $wpdb;
    if ( $wpdb->get_var( $wpdb->prepare( 'SELECT post_id FROM .'$wpdb->prefix.'postmeta WHERE post_id = %d', $pid ) ) ) {
        $wpdb->query( $wpdb->prepare( 'DELETE FROM '.$wpdb->prefix.'postmeta WHERE post_id = %d', $pid ) );
    }
}
?>
