Get woocommerce carts total amount

Question

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...

Answer 1

Try this:

WC()->cart->cart_contents_total

The function get_cart_total uses wc_price function thas converts cart_contents_total to currency.
