列的值parent_affiliate_id，将其存储在affiliate_id = $get_id中并显示它。
我是WordPress的新手。请帮我。预先谢谢你
$parent_traced_id答案 0 :(得分：0)
在代码中，您将值存储在名为“ parent_traced_id”的变量中，它将仅存储将循环的最后一个值。您可以使用数组而不是变量，因此它将存储将在for循环中循环的所有值。并且您正在使用echo“ $ parent_traced_id”显示变量；使用echo $ parent_traced_id。要显示所有值，请使用print_r（$ parent_traced_id）。
global $wpdb;
$table1 = $wpdb->prefix . "users";
$results = $wpdb->get_results("SELECT *
FROM ".$table1);
foreach($results as $row){
$row_id[] = $row->ID;
}
print_r($row_id);
