php - Save WooCommerce product data to database based on other inputs calculation
Get the solution ↓↓↓
I am looking for a way to save data to a database base on other inputs, I have awoocommerce_wp_text_input and I use it to calculate the price per unit:
I usewoocommerce_wp_text_input( $ppuvnumber ); for getting the net weight (without packaging) and I useget_price(); for price. Then I use this formula to calculate the price per unit:
$product_att = wc_get_product ( $post->ID );
$price_to_use = $product_att->get_price();
$amount_to_use = $product_att->get_meta( 'rasa_store_product_ppu_number' );
$calculation = round( $price_to_use/$amount_to_use, 2) ;
I want to save the amount of$calculation to database asmeta_key . Now I am a little bit confuse and have two questions:
- Should I create a new
woocommerce_wp_text_inputand hide it? - Is it possible to save the result of
$calculationto database without creatingwoocommerce_wp_text_input?

Solution:
Yes it's possible: You can use theWC_Data methodsupdate_meta_data() andsave() on theWC_Product object to add a custom field.
You just need to define under what meta key for that custom field.
On the code below replacesome_meta_key by the desired meta key:
$product = wc_get_product( $post->ID ); // get the product Object
$price = $product->get_price(); // The product price
$ppu_number = $product->get_meta( 'rasa_store_product_ppu_number' ); // Get some custom meta data
$calculation = round( $price/$ppu_number, 2) ; // Make the calculation
$product->update_meta_data('some_meta_key', $calculation); // Set the calculation as a new custom meta data
$product->save(); // Save to database
It should work.
You can also use WordPressupdate_post_meta() as follows (the old way):
$product = wc_get_product( $post->ID ); // get the product Object
$price = $product->get_price(); // The product price
$ppu_number = $product->get_meta( 'rasa_store_product_ppu_number' ); // Get some custom meta data
$calculation = round( $price/$ppu_number, 2) ; // Make the calculation
update_post_meta( get_the_ID(), 'some_meta_key', $calculation ); // Set and save the calculation as a new custom meta data
