WooCommerce 教程：當有免費送貨時隱藏其他送貨選項

如果您想要為特定國家/地區僅顯示一種運送方式，則需要一些額外的編碼。在此示例中，我們將禁用所有運送方式，但 “免費送貨” 。這裡是新增到您的 functions.php 的 PHP 程式碼

程式碼段＃1：在 1 個運送區域中取消設定 1 個免費版本

要找到新的 “運送方式名稱”，例如 “ free_shipping：8 ”

  /**   * @snippet       Hide one shipping option in one zone when Free Shipping is available     * @sourcecode    https://businessbloomer.com/?p=260   * @author        Rodolfo Melogli   * @compatible    WooCommerce 3.1.1   */    add_filter( 'woocommerce_package_rates', 'bbloomer_unset_shipping_when_free_is_available_in_zone', 10, 2 );     function bbloomer_unset_shipping_when_free_is_available_in_zone( $rates, $package ) {   	   	// Only unset rates if free_shipping is available    	if ( isset( $rates['free_shipping:8'] ) ) {    	unset( $rates['flat_rate:1'] );  }  	  	  return $rates;    }

程式碼段＃1：在可用空閒時，在所有區域中取消設定所有費率

  /**   * @snippet       Hide ALL shipping rates in ALL zones when Free Shipping is available     * @sourcecode    https://businessbloomer.com/?p=260   * @author        Rodolfo Melogli   * @compatible    WooCommerce 3.1.1   */    add_filter( 'woocommerce_package_rates', 'bbloomer_unset_shipping_when_free_is_available_all_zones', 10, 2 );     function bbloomer_unset_shipping_when_free_is_available_all_zones( $rates, $package ) {   	   	$all_free_rates = array();  	          foreach ( $rates as $rate_id => $rate ) {  		if ( 'free_shipping' === $rate->method_id ) {  			$all_free_rates[ $rate_id ] = $rate;  			break;  		}  	}  	  	if ( empty( $all_free_rates )) {          return $rates;          } else {          return $all_free_rates;          }   }

對於舊版本的 WooCommerce [2.1-2.5]（當 Free 可用時，取消設定一個速率）

  /**   * @snippet       Hide one shipping option when Free Shipping is available     * @sourcecode    https://businessbloomer.com/?p=260   * @author        Rodolfo Melogli   * @compatible    WooCommerce 2.4.10   */    add_filter( 'woocommerce_package_rates', 'bbloomer_unset_shipping_when_free_is_available', 10, 2 );     function bbloomer_unset_shipping_when_free_is_available( $rates, $package ) {   	   	// Only unset rates if free_shipping is available    	if ( isset( $rates['free_shipping'] ) ) {    		unset( $rates['flat_rate'] );    		return $rates;  }    }

對於舊版本的 WooCommerce [2.1-2.5]（免費提供時，設定所有費率）

  /**   * @snippet       Hide ALL shipping options when Free Shipping is available     * @sourcecode    https://businessbloomer.com/?p=260   * @author        Rodolfo Melogli   * @compatible    WooCommerce 2.4.10   */    add_filter( 'woocommerce_package_rates', 'bbloomer_unset_shipping_when_free_is_available', 10, 2 );     function bbloomer_unset_shipping_when_free_is_available( $rates, $package ) {   	   	// Only unset rates if free_shipping is available    	if ( isset( $rates['free_shipping'] ) ) {    	    	$free_shipping = $rates['free_shipping'];  	$rates = array();  	$rates['free_shipping'] = $free_shipping;  	}  	  	return $rates;  }

請注意：如果您無法使其工作，您必須清除 WooCommerce 快取（WooCommerce> 系統狀態）。見下圖。

達到 WooCommerce 2.1

  // Hide standard shipping option when free shipping is available  add_filter( 'woocommerce_available_shipping_methods', 'hide_standard_shipping_when_free_is_available' , 10, 1 );     /**   *  Hide Standard Shipping option when free shipping is available   *    * @param array $available_methods   */  function hide_standard_shipping_when_free_is_available( $available_methods ) {         if( isset( $available_methods['free_shipping'] ) AND isset( $available_methods['flat_rate'] ) ) {             // remove standard shipping option          unset( $available_methods['flat_rate'] );      }         return $available_methods;  }
