更新自定義字段值

Question

我需要更新基於值從一些自定義字段的產品價格

這是我是如何建立和保存自定義字段，最後我想要當我保存，更新，發佈產品時，根據海關字段的值更新_regular_price，但沒有任何事情發生，我錯過了什麼？

所有的代碼進入function.php現在

//BUILD AND SAVE FIELDS 
// Display Fields 
add_action('woocommerce_product_options_general_product_data', 'woo_add_custom_general_fields'); 

function woo_add_custom_general_fields() { 

    global $woocommerce, $post; 

    echo '<div class="options_group">'; 

// Product URL 
woocommerce_wp_checkbox( 
array( 
    'label' => __('Product URL', 'woocommerce'), 
    $post_id = $_GET['post'], 
    $produrl = get_post_meta($post_id, 'productOriginalUrl', true), 
    'description' => '<a href="' . $produrl . '" class="button button-primary button-large" target="_blank">' . __('View Product', 'woocommerce') . '</a>', 
    ) 
); 

    // Number Field 
woocommerce_wp_text_input( 
    array( 
     'id'    => '_price_usd', 
     'label'    => __('Price in USD', 'woocommerce'), 
     'placeholder'  => '', 
     'description'  => __('Enter the custom value here.', 'woocommerce'), 
     'type'    => 'number', 
     'custom_attributes' => array(

     '7.5' => __('0.5 KG', 'woocommerce'), 
     '15' => __('1 KG', 'woocommerce') 
     ) 
    )

     } 

} 
add_action('woocommerce_process_product_meta', 'wpa104760_default_price'); 

Answer 1

答案很簡單，

它需要一個過濾器來更新_regular_price和_sale_price

//price new 

function return_custom_price($price, $product) { 
global $post; 
$new_total = get_post_meta($post->ID, '_total_egp', true); 
$price = get_post_meta($post->ID, '_regular_price', true); 
$sale_price = get_post_meta($post->ID, '_sale_price', true); 
$now_price = get_post_meta($post->ID, '_price', true); 

if($price != 0){ 
update_post_meta($post->ID, '_regular_price', $new_total); 
update_post_meta($post->ID, '_sale_price', $new_total); 
update_post_meta($post->ID, '_price', $new_total); 
return $price; 
    } 
} 
add_filter('woocommerce_get_price', 'return_custom_price', 10, 2);
