I have issue with updating of product price from external database. I need to check price of product in every access to this position. For that I use the_post hook. For example I got '1718' price value for single product.
function chd_the_post_action( $post ) {
if ( $post && $post->post_type == 'product' ) {
$product = wc_get_product( $post->ID );
if ( $product ) {
$price = '1718';
$product->set_price( "$price" );
$product->set_regular_price( "$price" );
$product->set_sale_price( "$price" );
$product->save();
}
}
}
This code update product price in database, but it's not change view of price on page in the same moment, but only after page reload because post and product variables was setup by setup_postdata().
Therefore I use woocommerce hook for display updated price:
function chd_get_price_filter( $price, $item ) {
return '1718';
}
add_filter( 'woocommerce_product_get_price', 'chd_get_price_filter', 100, 2 );
add_filter( 'woocommerce_product_get_regular_price', 'chd_get_price_filter', 100, 2 );
add_filter( 'woocommerce_product_get_sale_price', 'chd_get_price_filter', 100, 2 );
Is there any hook in which I can do this action in better way?
Update product price using update_post_meta function like this
update_post_meta( $product->id, '_sale_price', '1718' );
update_post_meta( $product->id, '_regular_price', '1718 );
add_action( 'the_post', 'chd_the_post_action', 9, 1);

I am adding a custom field to woocommerce product variations to attach additional product categories to product variations. Everything works, during the save process the terms are updated in wp_term_relationships table however, a bit later in the save operation the terms are overwritten again with the parent product ones.
I am using the following code:
add_action( 'woocommerce_save_product_variation', 'save_custom_field_variations', 99, 2 );
function save_custom_field_variations( $variation_id, $i ) {
$custom_categories = $_POST['variation_product_cat'][$variation_id];
if ( isset( $custom_categories ) && !empty( $custom_categories )) {
wp_set_post_terms( $variation_id, $custom_categories, 'product_cat' );
}
}
I have also tried a different hook with the same result:
add_action( 'woocommerce_update_product', 'save_custom_field_variations_2', 99, 1 );
function save_custom_field_variations_2( $post_id ) {
foreach($_POST['variation_product_cat'] as $variation_id => $custom_categories)
if ( isset( $custom_categories ) && !empty( $custom_categories )) {
$response = wp_set_post_terms( $variation_id, $custom_categories, 'product_cat' );
}
}
Any tips on what process is overwriting my changes are very welcome!
Turns out it was one of the plugins that was overwriting the changes (found out by disabling all and then enabling them one by one)
Shipping rates are calculated using product weight and dimension on my Woocommerce website. However, my inventory system only uses product weight for shipping rates. Because of this, new products synchronized from the inventory system to the website generally don't have dimensions.
After a few tests, I found that adding a length, width and height of .001 to products on the site generates the most accurate shipping rates.
I need to write a function that sets product dimensions to .001 if they're empty at the point of creation.
Here is what I've attempted:
function add_default_dimension_if_empty( $meta_id, $post_id, $meta_key, $meta_value ) {
if ( $meta_key == '_edit_lock' ) {
if ( get_post_type( $post_id ) == 'product' ) {
//get product
$product = wc_get_product( $post_id );
$newDim = .001;
if($product->has_dimensions()){
if(empty( $product->get_length() )){
update_post_meta($post_id, '_length', $newDim);
}
if(empty( $product->get_width() )){
update_post_meta($post_id, '_width', $newDim);
}
if(empty( $product->get_height() )){
update_post_meta($post_id, '_height', $newDim);
}
}
}
}
}
add_action( 'added_post_meta', 'add_default_dimension_if_empty', 10, 4 );
add_action( 'updated_post_meta', 'add_default_dimension_if_empty', 10, 4 );
I used the structure from this article, but it doesn't seem to work. Any thoughts?
Your code is fine just need to change one condition which check the dimension is exist or not.
Replace if($product->has_dimensions()) line with following
$dimensions = $product->get_dimensions();
if(! empty( $dimensions ))
This will work for you.
My Goal: I am using WooCommerce with WCVendor plugin. All vendors have a taxonomy of location. Similarly all products publish by them have taxonomy called 'Product Location'. When vendors add new product, they have to select their location(s) everytime. Now, I would like to run a program that will update their product's location(s) according to their location.
I have managed to get a snippet by searching online -
add_action( 'added_post_meta', 'mp_sync_on_product_save', 10, 4 );
add_action( 'updated_post_meta', 'mp_sync_on_product_save', 10, 4 );
function mp_sync_on_product_save( $meta_id, $post_id, $meta_key, $meta_value ) {
if ( $meta_key == '_edit_lock' ) { // we've been editing the post
if ( get_post_type( $post_id ) == 'product' ) { // we've been editing a product
$product = wc_get_product( $post_id );
// Find the locations of author and save it as product's location
}
}
}
Can anyone please help?
Thank you.
I have a Woocommerce store set up with various product categories.
I want to apply a 20% discount to all products, which belong to the product category Cuckoo
For now all I'm trying to achieve is set a sale price in my functions.php
It tried as follows:
/*
* For a specific date, 20% off all products with product category as cuckoo clock.
*/
function cuckoo_minus_twenty($sale_price, $product) {
$sale_price = $product->get_price() * 0.8;
return $sale_price;
};
// add the action
add_filter( 'woocommerce_get_sale_price', 'cuckoo_minus_twenty', 10, 2 );
If I var_dump the result of $sale_price after the calculation I get the correct answer, however the price display on the front-end strikes out the regular price and displays the sale price as the regular price.
Is there a hook/filter I can use to achieve this?
I've also tried setting the sale price by doing:
$product->set_sale_price($sale_price);
to no avail.
The hook woocommerce_get_sale_price is deprecated since WooCommerce 3 and replaced by woocommerce_product_get_sale_price.
Also Product displayed prices are cached. When sale price is active, regular price is also active.
Try this instead:
// Generating dynamically the product "regular price"
add_filter( 'woocommerce_product_get_regular_price', 'custom_dynamic_regular_price', 10, 2 );
add_filter( 'woocommerce_product_variation_get_regular_price', 'custom_dynamic_regular_price', 10, 2 );
function custom_dynamic_regular_price( $regular_price, $product ) {
if( empty($regular_price) || $regular_price == 0 )
return $product->get_price();
else
return $regular_price;
}
// Generating dynamically the product "sale price"
add_filter( 'woocommerce_product_get_sale_price', 'custom_dynamic_sale_price', 10, 2 );
add_filter( 'woocommerce_product_variation_get_sale_price', 'custom_dynamic_sale_price', 10, 2 );
function custom_dynamic_sale_price( $sale_price, $product ) {
$rate = 0.8;
if( empty($sale_price) || $sale_price == 0 )
return $product->get_regular_price() * $rate;
else
return $sale_price;
};
// Displayed formatted regular price + sale price
add_filter( 'woocommerce_get_price_html', 'custom_dynamic_sale_price_html', 20, 2 );
function custom_dynamic_sale_price_html( $price_html, $product ) {
if( $product->is_type('variable') ) return $price_html;
$price_html = wc_format_sale_price( wc_get_price_to_display( $product, array( 'price' => $product->get_regular_price() ) ), wc_get_price_to_display( $product, array( 'price' => $product->get_sale_price() ) ) ) . $product->get_price_suffix();
return $price_html;
}
Code goes in function.php file of your active child theme (active theme).
Tested and works on single product, shop, product category and tag archive pages.

Wrong Woocommerce cart item price after setting programmatically product sale price
I realiced, you more or less need all of the following filters to make the HTML work out of the box.
add_filter( 'woocommerce_product_get_price', 'custom_dynamic_sale_price', 10, 2 );
add_filter( 'woocommerce_product_variation_get_price', 'custom_dynamic_sale_price', 10, 2 );
add_filter( 'woocommerce_product_get_sale_price', 'custom_dynamic_sale_price', 10, 2 );
add_filter( 'woocommerce_product_variation_get_sale_price', 'custom_dynamic_sale_price', 10, 2 );
add_filter( 'woocommerce_variation_prices_price', 'custom_dynamic_sale_price', 10, 2 );
add_filter( 'woocommerce_variation_prices_sale_price', 'custom_dynamic_sale_price', 10, 2 );
And you need to make sure you've changed the woocommerce_get_variation_prices_hash becasue of the stored transients if you want to display it correctly for variable products.
You may find the gist i've created for a client useful
https://gist.github.com/xandl/743fb6af60827eb95ad42b20b478b020
use woocomerce_get_sale_price filter.
add_filter('woocommerce_get_sale_price', 'my_custom_price', 99, 2);
add_filter('woocommerce_get_price', 'my_custom_price', 99, 2);
function my_custom_price( $price, $product )
{
//your logic for calculating the new price here
$price = $product->get_regular_price() * 0.8;
//Return the new price (this is the price that will be used everywhere in the store)
return $price;
}
I made a new post type named "sub_products" containing the meta tag "unit_price".
After assigning a new field for every Woocommerce product containing a list of all the "sub_products" posts, the goal was to update every product price based on the selected "sub_products" meta "unit_price".
function kulcskron_edit_post( $p1, $p2 )
{
if ( !is_admin() )
return;
if ( get_post_type() != 'product' )
return;
$sub_product_ids = $p2->get_meta( 'sub_products' );
if ( empty($sub_product_ids) )
return;
$product_regular_price = 0;
foreach ( $sub_product_ids as $id )
$product_regular_price += get_post_meta( $id, 'unit_price', true );
if ( $p1 == $product_regular_price )
return;
$p2->set_regular_price( $product_regular_price );
$p2->save();
}
add_action( 'woocommerce_product_get_price', 'kulcskron_edit_post', 10, 2 );
I tried every possible hook to make this work:
add_action( 'the_post', 'kulcskron_edit_post', 9, 1 );
add_action( 'edit_post', 'kulcskron_edit_post', 10, 2 );
add_action( 'pre_get_posts', 'kulcskron_edit_post' );
add_action( 'save_post', 'kulcskron_edit_post' );
This code updates the price but in a strange way:
Admin single product edit view: The price is not updated right away, just after I revisit the edit screen.
Admin product listing view: Every price is 0.
Front-end product page view: The displayed price is 0.
How do I update the product price based on the assigned "sub_products" "unit_price" post meta when a single product is saved in admin view?
You may use the hook "woocommefrce_get_price_html" it should work
I managed to solve the price update problem.
I used the save_post action:
save_post is an action triggered whenever a post or page is created or updated, which could be from an import, post/page edit form, xmlrpc, or post by email.
The final code:
function kulcskron_update_product( $product_obj )
{
if ( !is_admin() )
return;
if ( get_post_type() != 'product' )
return;
$product = wc_get_product( $product_obj );
if ( !$product->meta_exists( 'sub_products' ) )
return;
$sub_product_ids = $product->get_meta( 'sub_products' );
if ( empty($sub_product_ids) )
return;
_update_product_price( $product_obj, $sub_product_ids );
}
add_action( 'save_post', 'kulcskron_update_product' );
And for the sake of completeness here is the rest of code:
function _update_product_price( $product_obj, $sub_product_ids )
{
$product = wc_get_product( $product_obj );
$product_regular_price = 0;
foreach ( $sub_product_ids as $id )
$product_regular_price += get_post_meta( $id, 'kulcskron_unit_price', true );
$product->set_regular_price( $product_regular_price );
$product->set_price( $product_regular_price );
$product->save();
}
This way basically everything can be edited and updated. Example:
function _update_product_stock( $product_obj, $sub_product_ids )
{
$product = wc_get_product( $product_obj );
$sub_product_stocks = array();
foreach ( $sub_product_ids as $id )
$sub_product_stocks[] = get_post_meta( $id, 'kulcskron_free_stock_quantity', true );
$product->set_manage_stock( true );
$product->set_stock_quantity( min($sub_product_stocks) );
$product->save();
}
I would love to post a link to all the methods to edit a product but I have no rep for that.
But sadly this is not all...
In order to fully update the price, we need to filter the price HTML to return the newly updated price.
function kulcskron_price_html( $priceHtml, $product )
{
$symbol = get_woocommerce_currency_symbol();
$price = $product->get_regular_price();
$html = '<span class="woocommerce-Price-amount amount">'. $price .' <span class="woocommerce-Price-currencySymbol">'. $symbol .'</span></span>';
return $html;
};
add_filter( 'woocommerce_get_price_html', 'kulcskron_price_html', 10, 2 );
A little backstory. We need to sync all the products from an external database through an XML file. But there is a catch, the XML file only contains product parts and they are not displayed, searched, filtered and certainly can't be ordered individually. None of the Woocommerce build in functionality meet these requirements.
In order to solve this, I registered a new post type and imported all the product parts into this newly created post type. After that, I registered a new field for every WC Product with the Advanced Custom Fields plugin.
It looks like this:
Newly registered custom post type with the custom fields
The code above makes easy to update the WC Products (e.g. Prices) based on the selected Sub products.
