How to discount a product in an Opencart template using PHP?

Question

opencart

I want to manually make a 3% discount on a product and display the finished result with a 3% discount under the price in the template.
I take the $price price variable and write the code in the template:

$price = 6457;
<?php echo $price * 0.03; ?>

But the template displays some incomprehensible numbers 0.18.

Answer 1

First, if you run your code, the result will be 193.71, and 0.18. Check that your price contains exactly what you wrote.
Secondly, your discount formula is wrong. You calculate 3% and you need to decrease the price by 3%. For example, like this: Well, in the template later
$salePrice = $price - ($price/100*3);
<?= $salePrice ?>
