Woocommerce 过滤器自定义（四舍五入 vs 下限）

Question

我在 Woocommerce 源代码中有这个过滤器：

$this->total = max( 0, apply_filters( 'woocommerce_calculated_total', round( $this->cart_contents_total + $this->tax_total + $this->shipping_tax_total + $this->shipping_total + $this->fee_total, $this->dp ), $this ) );

我想通过我的过滤器应用此更改，但我不明白如何。

$this->total = max( 0, apply_filters( 'woocommerce_calculated_total', floor(( $this->cart_contents_total + $this->tax_total + $this->shipping_tax_total + $this->shipping_total + $this->fee_total) * 100)/100, $this ) ); 

任何帮助将不胜感激。问候！

Answer 1

完成！

function custom_round_function( $total, $cart ) {

$total = floor(($cart->cart_contents_total + $cart->tax_total + $cart->shipping_tax_total + $cart->shipping_total + $cart->fee_total) * 100)/100;

return $total;
}

add_filter( 'woocommerce_calculated_total', 'custom_round_function', 10, 2 );
