Woocommerce PHP - php

Question

I have a lot of custom fields in my WooCommerce checkout, and I'm trying to display them all on the admin page.
The number of fields varies from user to user, therefor I need to figure out how many fields of the name "$order-billing_date_of_birth" there is.
$order-billing_date_of_birth1
$order-billing_date_of_birth2
$order-billing_date_of_birth3
...and so on
I thought maybe I could use a loop like this.
for ($x = 0; $x <= 100; $x++) {
echo '<p><strong>'.__('Date of birth').'</strong>: ' . $order->billing_date_of_birth.$x . '</p>';
}
My question is: How do I combine the two "billing_date_of_birth" and "$x" to work as "$order->billing_of_birth1".
There's probably better ways to solve this as well.

Answer 1

Following is what you need to do
for ($x = 0; $x <= 100; $x++) {
$prop = "billing_date_of_birth".$x ;
echo '<p><strong>'.__('Date of birth').'</strong>: ' . $order->$prop . '</p>';
}

Answer 2

Here is an example code to achieve the requirements.
Converting the Object to array and then finding the element.
<?php
$object = new StdClass;
$object->foo1 = 'Hey';
$object->bar1 = 'Friend';
$array_obj=(array) $object;
//var_dump( $array_obj );
$bar='bar';
$num=1;
echo ($array_obj[$bar.$num]);
?>

Try something similar, applied to a class.
for example
list-group-item1
list-group-item2
list-group-item3
With this code
jQuery(function($) {
$('.list-group-item').each(function(i) {
$(this).attr('class',"list-group-item"+i);
});
});
