Call the results from a previous Foreach - php

Question

I am trying to get the results from my Foreach in another echo way later then the foreach but I am stuck, any help would be much appericated.
$items = $order->get_items();
// Output the loop
foreach ($order->get_items() as $item) {
// Getting some information
$product_qty = $item['qty'];
$product_variation_id = $item['variation_id'];
$product = new WC_Product($item['product_id']);
// SKU
$SKU = $product->get_sku();
print_r($SKU);
print_r($product_qty);
print_r(' ');
}
// this gives all 3 quantities and all 3 sku, added a space at the end for easier reading
// this only gives the 1st entry of both variables but i need all 3 of both variables
echo '<a href="https://www.domainname.someurl'.$product_quantity .$SKU . '" target=_blank>';
echo "<p>TEXT</p></a>";
I hope it is clear like this, thanks

Answer 1

Well, you're overwriting the value of $SKU and product_qty on each iteration, maybe try storing them in an array? Like create an array outsite the loop and use array_push(created_array, array($SKU, $product_qty)). Hope it helps.
$items = $order->get_items();
$push = array();
// Output the loop
foreach ($order->get_items() as $item) {
// Getting some information
$product_qty = $item['qty'];
$product_variation_id = $item['variation_id'];
$product = new WC_Product($item['product_id']);
// SKU
$SKU = $product->get_sku();
array_push($push, array('sku'=>$SKU, 'qty'=>$product_qty));
print_r($SKU);
print_r($product_qty);
print_r(' ');
}
// this gives all 3 quantities and all 3 sku, added a space at the end for easier reading
// this only gives the 1st entry of both variables but i need all 3 of both variables
$link = '<a href="https://www.domainname.someurl';
for ($i=0;$i<count($push);$i++){
$link .= $push[$i]['qty'];
$link .= $push[$i]['sku'];
}
$link .= '" target=_blank>';
echo $link;

Try the below code
$items = $order->get_items();
// Output the loop
$product_qty_string = '';
$sku_string = '';
foreach ($order->get_items() as $item) {
// Getting some information
$product_qty_string .= $item['qty']."-";
// SKU
$SKU = $product->get_sku();
$sku_string .=$SKU."-";
}
$product_quantity = rtrim($product_qty_string,'-');
$SKU = rtrim($sku_string,'-');
echo '<a href="https://www.domainname.someurl'.$product_quantity.''.$SKU.''" target=_blank>';
echo "<p>TEXT</p></a>";

Why don't you add your values in a array and then implode them.
$items = $order->get_items();
// Output the loop
$SKU = $product_qty = [];
foreach ($order->get_items() as $item) {
// Getting some information
$product_qty[] = $item['qty'];
$product_variation_id = $item['variation_id'];
$product = new WC_Product($item['product_id']);
// SKU
$SKU[] = $product->get_sku();
print_r($SKU);
print_r($product_qty);
print_r(' ');
}
$sku_string = implode('-', $SKU);
$product_qty_string = implode('-', $product_qty);
echo '<a href="https://www.domainname.someurl'.$product_qty_string .$sku_string . '" target=_blank>';
echo "<p>TEXT</p></a>";
You can implode your data with any separator you want, i use "-" for my example but its depending on your needs.
