How to display the value of a specific Opencart product option on the category page?

Question

PHP

Hello! I ran into a problem in Opencart. It is necessary to display the value of the product size option
in a small product card (the one that is displayed in categories, search, etc.) .
Some products have multiple sizes,
others only one. Others do not have this option.
In the case when the product has only one size option - we display the size, in the case when there are several - "Sizes to choose from", when there is no size - we do not display anything.
Through <?php var_dump($product['options']) ?>
I dumped all the elements of the array with options.
array(2) { [0]=> array(7) { ["product_option_id"]=> string(4) "1504" ["product_option_value"]=> array(7) { [0]=> array(6) { ["product_option_value_id"]=> string(5) "17905" ["option_value_id"]=> string(3) "609" ["name"]=> string(10) "White" ["image"]=> NULL ["price"]=> bool(false) ["price_prefix"]=> string(1) "+" } [1]=> array(6) { ["product_option_value_id"]=> string(5) "17906 " ["option_value_id"]=> string(3) "598" ["name"]=> string(14) "Beige" ["image"]=> NULL ["price"]=> bool(false) [" price_prefix"]=> string(1) "+" } [2]=> array(6) { ["product_option_value_id"]=> string(5) "17907" ["option_value_id"]=> string(3) "604" ["name"]=> string(12) "Laguna" ["image"]=> NULL [" price"]=> bool(false) ["price_prefix"]=> string(1) "+" } [3]=> array(6) { ["product_option_value_id"]=> string(5) "17621" [" option_value_id"]=> string(3) "601" ["name"]=> string(20) "Purple" ["image"]=> NULL ["price"]=> bool(false) ["price_prefix"] => string(1) "+" } [4]=> array(6) { ["product_option_value_id"]=> string(5) "17909" ["option_value_id"]=> string(3) "701" [" name"]=> string(14) "Pink" ["image"]=> NULL ["price"]=> bool(false) ["price_prefix"]=> string(1) "+" } [5]=> array(6) { ["product_option_value_id"]=> string (5) "17910" ["option_value_id"]=> string(3) "700" ["name"]=> string(12) "Peach" ["image"]=> NULL ["price"]=> bool (false) ["price_prefix"]=> string(1) "+" } [6]=> array(6) { ["product_option_value_id"]=> string(5) "17911" ["option_value_id"]=> string (3) "702" ["name"]=> string(35) "Intense pink" ["image"]=> string(90) "product_option_value_id"]=> string(5) "17910" ["option_value_id"]=> string(3) "700" ["name"]=> string(12) "Peach" ["image"]=> NULL [" price"]=> bool(false) ["price_prefix"]=> string(1) "+" } [6]=> array(6) { ["product_option_value_id"]=> string(5) "17911" [" option_value_id"]=> string(3) "702" ["name"]=> string(35) "Intense pink" ["image"]=> string(90) "product_option_value_id"]=> string(5) "17910" ["option_value_id"]=> string(3) "700" ["name"]=> string(12) "Peach" ["image"]=> NULL [" price"]=> bool(false) ["price_prefix"]=> string(1) "+" } [6]=> array(6) { ["product_option_value_id"]=> string(5) "17911" [" option_value_id"]=> string(3) "702" ["name"]=> string(35) "Intense pink" ["image"]=> string(90) "} [6]=> array(6) { ["product_option_value_id"]=> string(5) "17911" ["option_value_id"]=> string(3) "702" ["name"]=> string(35) "Intense pink" ["image"]=> string(90) "} [6]=> array(6) { ["product_option_value_id"]=> string(5) "17911" ["option_value_id"]=> string(3) "702" ["name"]=> string(35) "Intense pink" ["image"]=> string(90) "inf-mebel.nichost.ru/image/cache/catalog/options/c..."

How can I access exactly that part of the array that is responsible for the size, in order to make a selection by the number of these sizes through if else and form the result for each case, as well as get the value of the size itself?
Thank you!

Answer 1

$size_options = array(17, ...); // id опций которые отвечают за размер, в примере это 17
foreach ($product['options'] as $option) {
  if (in_array( $option['option_id'], $size_options)) { // работаем только с теми опциями, которые отвечают за размер.
    ... // тут проверяем нудные вам условия
  }
}
