I am trying to apply a discount to a carts total price, but I can only do it to the item base price and not the over all price. I Googled and came across this post in the
wordpress stackoverflow:
$amount = floatval( preg_replace( '#[^\d.]#', '',
$woocommerce->cart->get_cart_total() ) ); The preg_replace eliminates
everything but decimal characters and colons.
Should you care to do math with it, the floatval converts the value
from a string to a numeric one.
I tried adding:
$amount2 = floatval( preg_replace( '#[^\d.]#', '', $woocommerce->cart->get_cart_total() ) );
and changing
$discount = round( (($discounting_amount / 100 ) * $this->amount)*-1, WC()->cart->dp);
to
$discount = round( (($discounting_amount / 100 ) * $amount2)*-1, WC()->cart->dp);
But I get the following error:
Fatal error: Call to a member function get_cart_total() on a non-object in...
You need to call the global variable to ensure that it gets the correct values.
If you add
global $woocommerce;
just before
$amount2 = floatval( preg_replace( '#[^\d.]#', '', $woocommerce->cart->get_cart_total() ) );
that should solve your problem.
Try this:
WC()->cart->cart_contents_total
The function get_cart_total uses wc_price function thas converts cart_contents_total to currency.
This works perfectly and removes currency symbol:
$woocommerce->cart->total;
global $woocommerce;
$amount = $woocommerce->cart->cart_contents_total+$woocommerce->cart->tax_total;
You can also convert $amount in float value as per your requirement.
To show the carts total including tax and discounts use this
$ordertotal = wp_kses_data( WC()->cart->get_total() );
$totalamount = $woocommerce->cart->cart_contents_total;
echo $totalamount;
As of late 2018, the best way is to use get_cart_contents_total()
. This is the total of items in the cart after discounts.
WC()->cart->get_cart_contents_total(); // Float
Other methods are available for more specific needs, just have a look at the docs.
