获取最后的购物车编号woocommerce

Question

I use woocommerce on wordpress. This is my code

<?php
global $woocommerce;
$items = $woocommerce->cart->get_cart();
foreach($items as $item => $values) { 
        $_product = $values['data']->post; 
        echo $_product->ID.','; 
} 
?>

And this is the result of teh code:

1297,1694,1297,3911,4999,

How can I get just last id '4999' ?

Answer 1

Storing the ids in an array and using the end() function would be a solution:

<?php
global $woocommerce;
$items = $woocommerce->cart->get_cart();
$ids = array();
foreach($items as $item => $values) { 
        $_product = $values['data']->post; 
        $ids[] = $_product->ID; 
} 

echo 'Last item = ' . end($ids);
?>

Answer 2

You can do it even simpler that what Akhilesh proposed - instead of iterating through $items array go to the last item there:

end($items)['data']->post->ID;

I am not sure, but probably you would need PHP 5.3+ for that.
