产品页面上的Woocommerce价格输出

Question

I need to mod a plugin for my needs. Plugin code is as follow:

1. update_post_meta($post_id, '_regular_price', (isset($product['price']) && !empty($product['price'])) ? $product['price'] : '');
2. update_post_meta($post_id, '_sale_price', (isset($product['sale-price']) && !empty($product['sale-price']) && ($product['sale-price']<$product['price']) ) ? $product['sale-price'] : '');
3. update_post_meta($post_id, '_price', (isset($product['price'])) ? $product['price'] : '');

First two rows input the regular price and discount (sale) price values into the database. The third row is the output on the product page, which I need to change so:

1. If discounted price _sale_price / [sale-price] is present it should be shown as default _price / [price] on row 3.
2. If discount price _sale_price / [sale-price] is not present the normal price from row 1 should be shown as [price] on row 3

I've tried if (isset($product['sale-price'])){? $product['sale-price'] : '';}else{? $product['price'] : '';} but this throws 500 error.

Any help appreciated.

WooCommerce should be doing this automatically, but in the interest of answering your question, there are some errors in your code, it seems like you are trying to mix a ternery operator with an IF statement.

The correct replacement for line 3 should look like this:

update_post_meta($post_id, '_price', (isset($product['sale-price']) && !empty($product['sale-price'])) ? $product['sale-price'] : $product['price']);
