For some reason this "OR" statement is not working:
if($product->virtuemart_product_id != 153 || 170 || 171 || 195 || 208){
//code here
}
It works when I only use one ID, but when I add many it doesn't work. Any ideas what could be wrong?
You are doing it wrong. The correct way is:
if($product->virtuemart_product_id != 153 ||
$product->virtuemart_product_id != 170 ||
$product->virtuemart_product_id != 171 ||
$product->virtuemart_product_id != 195 ||
$product->virtuemart_product_id != 208)
It looks messy, but this is the way to do it.
A cleaner approach would be:
$arr = [153,170,171,195,208];
if( ! in_array($product->virtuemart_product_id, $arr) )
