问题描述
基于我上一个问题的答案,
Based on the answer on my previous question, Issue display shipping data on WooCommerce single product page, I'm trying to replace the 0 with FREE or whatever word I choose.
Problem is, whatever I do, it does not work. This is my attempt and I need help with it:
add_action('woocommerce_after_add_to_cart_form', 'display_shipping_on_product_page', 10, 0);
function display_shipping_on_product_page(){
// get all zones
$zones = WC_Shipping_Zones::get_zones();
// get the shop base country
$base_country = WC()->countries->get_base_country();
$base_city = WC()->countries->get_base_city();
// start display of table
echo '<div>' . __( '<b>Available Shipping</b>', 'woocommerce' );
echo '<br><small><span class="shipping-time-cutoff">All orders are shipped from the '.$base_country.'. Order before 12AM Mon-Fri for same day delivery within '.$base_city.'. Order before 3PM Mon-Thu for next day delivery.</span></small>';
echo '<small><table class="shipping-and-delivery-table">';
// get name of each zone and each shipping method for each zone
foreach ( $zones as $zone_id => $zone ) {
echo '<tr><td>';
echo '<strong>' . $zone['zone_name'] . '</strong>' . '</td><td>';
$zone_shipping_methods = $zone['shipping_methods'];
foreach ( $zone_shipping_methods as $index => $method ) {
$instance = $method->instance_settings;
if ( isset( $instance['min_amount'] ) ) {
$instance_min_amount = $instance['min_amount'];
} else {
$instance_min_amount = 0;
}
if ( isset( $instance['cost'] ) ) {
$instance_cost = $instance['cost'];
} else {
$instance_cost = str_replace($instance_cost, "FREE" );
}
$cost = $instance_cost ? $instance_cost : $instance_min_amount;
$above = $instance_min_amount ? 'above ' : '';
echo $instance['title'] . ': ' . $above . '<strong>' . wc_price( $cost ) . '</strong>' . '<br>';
}
echo '</td></tr>';
}
echo '</table></small></div>';
}
This is what I tried to add / edit without success:
$instance_cost = str_replace($instance_cost, "FREE" );
解决方案
To display 'free' instead of 0, you need to change your if/else conditions. Explanation via comment tags added to my answer.
So you get:
function action_woocommerce_after_add_to_cart_form() {
// get all zones
$zones = WC_Shipping_Zones::get_zones();
// get the shop base country
$base_country = WC()->countries->get_base_country();
$base_city = WC()->countries->get_base_city();
// start display of table
echo '<div>' . __( 'Available Shipping', 'woocommerce' );
echo '<br><small><span class="shipping-time-cutoff">All orders are shipped from the '.$base_country.'. Order before 12AM Mon-Fri for same day delivery within '.$base_city.'. Order before 3PM Mon-Thu for next day delivery.</span></small>';
echo '<small><table class="shipping-and-delivery-table">';
// get name of each zone and each shipping method for each zone
foreach ( $zones as $zone_id => $zone ) {
echo '<tr><td>';
echo '<strong>' . $zone['zone_name'] . '</strong>' . '</td><td>';
$zone_shipping_methods = $zone['shipping_methods'];
foreach ( $zone_shipping_methods as $index => $method ) {
$instance = $method->instance_settings;
// Initialize
$above = '';
$output_cost = __( 'Free', 'woocommerce' );
// Cost isset
if ( isset( $instance['cost'] ) ) {
// NOT empty
if ( ! empty ( $instance['cost'] ) ) {
// Output
$output_cost = wc_price( $instance['cost'] );
}
}
// Min amount isset
if ( isset( $instance['min_amount'] ) ) {
// NOT empty
if ( ! empty ( $instance['min_amount'] ) ) {
// Above
$above = __( 'above ', 'woocommerce' );
// Output
$output_cost = wc_price( $instance['min_amount'] );
}
}
echo $instance['title'] . ': ' . $above . '<strong>' . $output_cost . '</strong>' . '<br>';
}
echo '</td></tr>';
}
echo '</table></small></div>';
}
add_action( 'woocommerce_after_add_to_cart_form', 'action_woocommerce_after_add_to_cart_form', 10, 0 );
