I want to get the cart total figure for which I am using the following code in my functions.php:
function display_total(){
global $woocommerce;
$newTotal = $woocommerce->cart->get_total();
echo $newTotal;
};
add_action( 'woocommerce_review_order_before_order_total', 'display_total');
Instead of displaying the amount once, it does it twice like $18.00$18.00.
Doing a var_dump too results in 2 lines of HTML:
D:\Wordpress\wp-content\themes\new_theme\functions.php:161:string '<span class="woocommerce-Price-amount amount"><bdi><span class="woocommerce-Price-currencySymbol">$</span>18.00</bdi></span>' (length=128)
D:\Wordpress\wp-content\themes\new_theme\functions.php:161:string '<span class="woocommerce-Price-amount amount"><bdi><span class="woocommerce-Price-currencySymbol">$</span>18.00</bdi></span>' (length=128)
What am I doing wrong?
Echo the value in a table row, so that it won't echo it twice. So your code would be something like this:
add_action( 'woocommerce_review_order_before_order_total', 'display_total');
function display_total(){
global $woocommerce;
$newTotal = $woocommerce->cart->get_total();
echo '<tr><td >' . $newTotal . '</td></tr>';
};
And the reason is, woocommerce_review_order_after_order_total hook is being used in a table, therefore adding your value between a tr and td tag would result in echoing the value once.
