Fatal error uncaught error call to a member function get_price() on null on WooCommerce

CMS & WordPress

HI,
I am using Flatsome theme with WooCommerce and I am working on WooCommerce API calls.
For Orders and Customers, it is working perfectly.
However, I get this error for Products:

fatal error uncaught error call to a member function get_price() on null in home/xxx/public_html/wp-content/plugins/woocommerce/inc/wc-products-functions.php 1046.

I have added the following code in this file location: /home/xxx/public_html/wp-content/themes/flatsome/woocommerce/single-product/price.php.

<?php
function sv_change_product_price_display( $price ) {
    global $product;
    $price_excl_tax = wc_get_price_excluding_tax( $product ); 
    $price_incl_tax = wc_get_price_including_tax( $product );  
    <p class="price">Ex. VAT:<?php echo wc_price( $price_excl_tax ); ?>
    <p class="price-incl">Incl. VAT: <?php echo wc_price( $price_incl_tax ); ?>
    <?php 
    //return $price;
}
add_filter( 'woocommerce_get_price_html', 'sv_change_product_price_display' );

I have added this code functions.php files:

<?php
function sv_change_product_price_display( $price ) {
    global $product;
    $price_excl_tax = wc_get_price_excluding_tax( $product ); 
    $price_incl_tax = wc_get_price_including_tax( $product );  
    <p class="price">Ex. VAT:<?php echo wc_price( $price_excl_tax ); ?>
    <p class="price-incl">Incl. VAT: <?php echo wc_price( $price_incl_tax ); ?>
    <?php 
    //return $price;
}
add_filter( 'woocommerce_get_price_html', 'sv_change_product_price_display' );

What I am doing wrong?

Thanks

Well for starters, your function is trying to output things without breaking from the PHP.

<?php
//Inside PHP...
function sv_change_product_price_display( $price ) {
    global $product;
    $price_excl_tax = wc_get_price_excluding_tax( $product ); 
    $price_incl_tax = wc_get_price_including_tax( $product );  //Still inside PHP...
   //Why is there HTML here?                  why is there a PHP tag inside PHP?
 <font color='red'><p class="price">Ex. VAT:<?php echo wc_price( $price_excl_tax ); ?>

Second of all, what is the value of $product? (and is the value of product what you THINK it is? Double check!

 }

Your error messages keep pointing me in the direction that $product is null. The stack trace seems to say that apply_filters did not send the product to your function; beyond that, someone with more knowledge of what wordpress does under the hood will have to weigh in, because I don’t know the appropriate method of handling this.

OK Bro but, Thanks for your help
