[Feature Request] Adding bulk actions for setting prices in variable products

I recently had a support chat about having the option to set custom prices for variable products with a bulk action like woocommerce has and i wanted to share my solution:

You can add code via plugin or in the functions.php file of a child theme to add the functionality in 2 steps.
First step is to add an action for the extra options to the "Bulk actions" dropdown (in my example with Euros). There are two options, one for the regular price and one for the sale price:

add_action( 'woocommerce_variable_product_bulk_edit_actions', 'set_euro_price_bulk_edit_variation', 10 );

function set_euro_price_bulk_edit_variation() {
?>
<optgroup label="Euro Price">
<option value="set_regular_euro_price">Set regular price</option>
<option value="set_sale_euro_price">Set sale price</option>
</optgroup>
<script>
jQuery( function(){
jQuery( 'select.variation_actions' ).on( 'set_regular_euro_price_ajax_data', function(e, data) {
var value = window.prompt( "enter regular price" );

if ( value !== null ) {
data.value = value;
return data;
} else {
return;
}
});
jQuery( 'select.variation_actions' ).on( 'set_sale_euro_price_ajax_data', function(e, data) {
var value = window.prompt( "enter sale price" );

if ( value !== null ) {
data.value = value;
return data;
} else {
return;
}
});
});
</script>
<?php
}

This includes a script to collect the price values via JS prompt.

The second step is to add an action to process the data afterwards which is just editing post meta:

add_action( 'woocommerce_bulk_edit_variations', 'set_euro_price_bulk_save', 10, 4 );

function set_euro_price_bulk_save( $bulk_action, $data, $product_id, $variations ) {
if( in_array( $bulk_action, [ 'set_regular_euro_price' ] ) ) {
if( isset( $data['value'] ) ) {
foreach( $variations as $variation_id ) {
// Update post meta will not update if variation_id exists, thus no check is necessary
// Else use if ( $variation = wc_get_product( $variation_id ) )
update_post_meta( $variation_id, '_regular_price_EUR', esc_attr( $data['value'] ) );
update_post_meta( $variation_id, '_price_EUR', esc_attr( $data['value'] ) );
update_post_meta( $variation_id, '_wcml_custom_prices_status', '1' );
}

}
}
if( in_array( $bulk_action, [ 'set_sale_euro_price' ] ) ) {
if( isset( $data['value'] ) ) {
foreach( $variations as $variation_id ) {
// Update post meta will not update if variation_id exists, thus no check is necessary
// Else use if ( $variation = wc_get_product( $variation_id ) )
update_post_meta( $variation_id, '_sale_price_EUR', esc_attr( $data['value'] ) );
update_post_meta( $variation_id, '_wcml_custom_prices_status', '1' );
}

}
}
}
