php - WooCommerce Free Shipping if over 5 pounds -


i'm trying write function offer free shipping (remove other options) if order on 5 pounds (80 ounces), doesn't work although code seems correct.

this have:

  // hide shipping options free when on 80 ounches (5 pounds) add_filter( 'woocommerce_available_shipping_methods', 'ship_free_if_over_five_pounds' , 10, 1 );  /** * hide shipping option free if on 5 pounds * * @param array $available_methods */ function ship_free_if_over_five_pounds( $available_methods ) {     global $woocommerce;     $whats_the_weight = $woocommerce->cart->cart_contents_weight;         if($whats_the_weight != 80) :          // free shipping array new array         $freeshipping = array();         $freeshipping = $available_methods['free_shipping'];          // empty $available_methods array         unset( $available_methods );          // add free shipping $avaialble_methods         $available_methods = array();         $available_methods[] = $freeshipping;      endif;      return $available_methods; }

any thoughts?

the code based on example #19 on site:
my 25 best woocommerce snippets wordpress part 2

i know old question, have recent alternative…

first, in code "if order on 5 pounds (80 ounces)" if statement should if($whats_the_weight > 80) instead of !=… think code little outdated if use woocommerce 2.6+.

after instead using global $woocommerce; $woocommerce->cart->cart_contents_weight; use: wc()->cart->cart_contents_weight;

i have more recent code snippet based on official thread woocommerce 2.6+. should try it:

add_filter( 'woocommerce_package_rates', 'my_hide_shipping_when_free_is_available', 100 );  function my_hide_shipping_when_free_is_available( $rates ) {      $cart_weight = wc()->cart->cart_contents_weight; // cart total weight      $free = array();     foreach ( $rates $rate_id => $rate ) {         if ( 'free_shipping' === $rate->method_id && $cart_weight > 80 ) { // <= weight condition             $free[ $rate_id ] = $rate;             break;         }     }     return ! empty( $free ) ? $free : $rates; }

for woocommerce 2.5, should try this:

add_filter( 'woocommerce_package_rates', 'hide_shipping_when_free_is_available', 10, 2 );  function hide_shipping_when_free_is_available( $rates, $package ) {      $cart_weight = wc()->cart->cart_contents_weight; // cart total weight      // modify rates if free_shipping present     if ( isset( $rates['free_shipping'] ) && $cart_weight > 80 ) { // here weight condition          // unset single rate/method, following. example unsets flat_rate shipping         unset( $rates['flat_rate'] );          // unset methods except free_shipping, following         $free_shipping          = $rates['free_shipping'];         $rates                  = array();         $rates['free_shipping'] = $free_shipping;     }      return $rates; }
