我创建了一个管理页面，在该页面中，我使用WP\\u list\\u Table显示MySQL表的列表。在这个表中，我需要能够在需要时删除记录。这就是我的问题所在。

要删除记录，我设置了以下代码。

class Genres_List extends WP_List_Table {

    [...]

    public static function delete_genre( $id ) {
        global $wpdb;
        $wpdb->delete(
            "{$wpdb->prefix}genres",
            [ \'id\' => $id ],
            [ \'%d\' ]
            );
    }

    function column_cb( $item ) {
        return sprintf(\'<input type="checkbox" name="id[]" value="%s" />\', $item[\'id\']);
    }

    function column_name( $item ) {
        $delete_nonce = wp_create_nonce( \'sp_delete_genre\' );
        $title = \'<strong>\' . stripslashes($item[\'name\']) . \'</strong>\';
        $actions = [
            \'edit\' => sprintf( \'<a href="?page=%s&action=%s&id=%s">Bewerken</a>\', esc_attr( $_REQUEST[\'page\'] ), \'edit\', absint( $item[\'id\'] ) ),
            \'delete\' => sprintf( \'<a href="?page=%s&action=delete&id=%s&_wpnonce=%s">Verwijderen</a>\', esc_attr( $_REQUEST[\'page\'] ), absint( $item[\'id\'] ), $delete_nonce )
            ];
        return \'<a href="?page=genres&action=edit&id=\' . $item[\'id\'] . \'"><strong>\' . stripslashes($item[\'name\']) . \'</strong>\' . $this->row_actions( $actions );
    }

    function get_columns() {
        $columns = [
            \'cb\' => \'<input type="checkbox" />\',
            \'name\' => \'Naam\'
            ];

        return $columns;
    }

    public function get_bulk_actions() {
        $actions = [
            \'delete\' => \'Verwijderen\'
            ];

        return $actions;
    }

    public function process_bulk_action() {
        if ( $this->current_action() === \'delete\' ) {
            if ( ! wp_verify_nonce( $_REQUEST[\'_wpnonce\'], \'sp_delete_genre\' ) ) {
                die(\'This is a secure website. Your nonce did not verify. Go get a coffee.\');
            } else {
                self::delete_genre( absint( $_GET[\'id\'] ) );
                wp_redirect( esc_url( add_query_arg() ) );
                exit;
            }

            if ( $_POST[\'action\'] === \'delete\' || $_POST[\'action2\'] === \'delete\') {
                $delete_ids = esc_sql( $_POST[\'id\'] );

                foreach ( $delete_ids as $id ) { self::delete_genre( $id ); }

                wp_redirect( esc_url( add_query_arg() ) );
                exit;
            }
        }
    }
}

问题是wp_verify_nonce( $_REQUEST[\'_wpnonce\'], \'sp_delete_genre\' ) 尝试删除记录时返回false。我似乎找不到我做错了什么，因为我完全遵循Wordpress Codex：

使用创建noncewp_create_nonce( \'sp_delete_genre\' )._wpnonce= 参数wp_verify_nonce( $_REQUEST[\'_wpnonce\'], \'sp_delete_genre\' )

if (is_array($_REQUEST[\'id\'])) {
    $true = wp_verify_nonce($_REQUEST[\'_wpnonce\'], \'bulk-\' . $this->_args[\'plural\']);
} else if (is_string($_REQUEST[\'id\'])) {
    $true = wp_verify_nonce($_REQUEST[\'_wpnonce\'], \'sp_delete_genre\');
}
