On our woocommerce website I am trying to update the displayed price based on the variations the customer selects from dropdown menus as shown here:
I used a php function that had been submitted in another answer by LoictheAztec:
Replace the Variable Price range by the chosen variation price in WooCommerce 3
add_action( 'woocommerce_before_single_product', 'move_variations_single_price', 1 );
function move_variations_single_price(){
global $product, $post;
if ( $product->is_type( 'variable' ) ) {
// removing the variations price for variable products
remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_price', 10 );
// Change location and inserting back the variations price
add_action( 'woocommerce_single_product_summary', 'replace_variation_single_price', 10 );
}
}
function replace_variation_single_price(){
global $product;
// Main Price
$prices = array( $product->get_variation_price( 'min', true ), $product->get_variation_price( 'max', true ) );
$price = $prices[0] !== $prices[1] ? sprintf( __( 'From: %1$s', 'woocommerce' ), wc_price( $prices[0] ) ) : wc_price( $prices[0] );
// Sale Price
$prices = array( $product->get_variation_regular_price( 'min', true ), $product->get_variation_regular_price( 'max', true ) );
sort( $prices );
$saleprice = $prices[0] !== $prices[1] ? sprintf( __( 'From: %1$s', 'woocommerce' ), wc_price( $prices[0] ) ) : wc_price( $prices[0] );
if ( $price !== $saleprice && $product->is_on_sale() ) {
$price = '<del>' . $saleprice . $product->get_price_suffix() . '</del> <ins>' . $price . $product->get_price_suffix() . '</ins>';
}
?>
<style>
div.woocommerce-variation-price,
div.woocommerce-variation-availability,
div.hidden-variable-price {
height: 0px !important;
overflow:hidden;
position:relative;
line-height: 0px !important;
font-size: 0% !important;
}
</style>
<script>
jQuery(document).ready(function($) {
$('select').blur( function(){
if( '' != $('input.variation_id').val() ){
if($('p.availability'))
$('p.availability').remove();
$('p.price').html($('div.woocommerce-variation-price > span.price').html()).append('<p class="availability">'+$('div.woocommerce-variation-availability').html()+'</p>');
console.log($('input.variation_id').val());
} else {
$('p.price').html($('div.hidden-variable-price').html());
if($('p.availability'))
$('p.availability').remove();
console.log('NULL');
}
});
});
</script>
<?php
echo '<p class="price">'.$price.'</p>
<div class="hidden-variable-price" >'.$price.'</div>';
}
However when a variation is selected it displays undefined underneath the From: $price as shown here:
Example of undefined error:
So if anyone could help me determine the cause of this error so that the price is now displayed and updated based on variations that have been selected it would be greatly appreciated.
