Php 如何获取删除帖子的所有帖子id？Wordpress

我在插件中创建了一个函数，当帖子移动到垃圾箱时，该函数将删除数据库行。但是，我无法使用

get\u posts（）

获取帖子id

这是我的密码：

function delete_condition($post)
{
    global $wpdb;

        $allposts = get_posts(array(
        'numberposts' => -1,
        'category' => 0, 'orderby' => 'date',
        'order' => 'DESC', 'include' => array(),
        'exclude' => array(), 'meta_key' => '',
        'meta_value' =>'', 'post_type' => 'job',
        'suppress_filters' => true));

        foreach( $allposts as $postinfo ) {
            $wpdb->delete('rule', array('post_id' => $postinfo));
        }

}
add_action('wp_trash_post', 'delete_condition', 10, 1);

谢谢

$postinfo是对象。您只需要post的ID。所以你应该写$postinfo->ID。用下面的代码替换你的循环-

foreach( $allposts as $postinfo ) {
            $postinfoID = $postinfo->ID;
            $wpdb->delete('rule', array('post_id' => $postinfoID));
   }

这里使用的操作挂钩，

wp\u trash\u post

，将$post\u id作为参数传递给函数。见：

听起来像是要从一个表中删除与被丢弃的表具有相同post ID的所有行

我想你可能想写这样的东西：

function delete_condition( $post_id ) {
 global $wpdb;
 // Delete rows in the rule table which have the same post_id as this one
 if ( 'job' === get_post_type( $post_id ) ) {
     $wpdb->delete('rule', array('post_id' => $post_id ) );
 }
}

add_action('wp_trash_post', 'delete_condition', 10, 1);

    <?php
function delete_condition($post)
{
    global $wpdb;

        $allposts = get_posts(array(
        'numberposts' => -1,
        'post_status' => 'any',
        'category' => 0, 'orderby' => 'date',
        'order' => 'DESC', 'include' => array(),
        'exclude' => array(), 'meta_key' => '',
        'meta_value' =>'', 'post_type' => 'job',
        'suppress_filters' => true));

        foreach( $allposts as $postinfo ) {
            $wpdb->delete('rule', array('post_id' => $postinfo));
        }

}
add_action('wp_trash_post', 'delete_condition', 10, 1);
?>
