Multiply Function Results in PHP

February 26, 20231 Views

I’m still beginner in PHP. I have a small problem, I would to multiply the value get_formatted_order_total(); with 3.75 and what I did is

get_formatted_order_total(); * 3.75

but It didn’t work.

here is the code

<li class="total">
    <?php _e('Total:', 'woocommerce'); ?>
    <strong><?php echo $order->get_formatted_order_total(); ?></strong>
</li>

Thank You

Semi-colons go at the end of an instruction. Since this is all one instruction, you need to move the semi-colon to the end of the line:
```
echo get_formatted_order_total() * 3.75;
```

Try so
```
echo get_formatted_order_total() * 3.75;
```
Without ; after ().
; should be after 3.75

The problem is, that get_formatted_order_total() returns a string, formatted for display on the website, not a numerical value that you can use for calculation.

The unformatted value is available as a member variable of the Order class, so
```
echo $order->order_total * 3.75;
```
should work.

In order to understand this, look at the source code of Woocommerce: Order::get_formatted_order_total() simply formats Order::order_total with a helper function woocommerce_price():
```
/** Gets order total - formatted for display */
function get_formatted_order_total() {
    $formatted_total = woocommerce_price( $this->order_total );

    return apply_filters( 'woocommerce_get_formatted_order_total', $formatted_total, $this );
}
```
