I have tried following code:

add_filter( 'woocommerce_get_price_html', 'custom_price_html', 10, 2 );
function custom_price_html(){
    global $product;

    $allowed_roles = array('editor', 'administrator', 'author');
    if( array_intersect($allowed_roles, $user->roles ) && !is_product() ) {
        if($product->is_type('simple')){
            $regular_price=$product->get_regular_price('min');
            $sale_price=$product->get_sale_price('min');
            if(!empty($sale_price)){

    }
}

Everything goes fine except probably due to using “woocommerce_get_price_html” function, on Single Product Page for a variable product showing same Price for all variations which is actually customized for Price to be shone next to Product Title.

E.g.: Case1: If the product have 4 Variations: Var1 reg price $50, Var2 reg price $80 sale price $40, var3 reg price $75 sale price $60 and var4 reg price $100. This product has no default variation set. The Price on Single Product should appear like ($80)striked off then $40. Which is appearing correct. But issue is in the dropdown when I select variation var1, the price shown below is ($80)striked off then $40 where as it should show $50. For all the variations when changed from var1 to var4, everytime it shows ($80)striked off then $40.

Case2: If the product have 4 Variations: Var1 reg price $50, Var2 reg price $80 sale price $40, var3(set default) reg price $75 sale price $60 and var4 reg price $100. The Price on Single Product should appear like ($75)striked off then $60. Which is appearing correct. But issue is in the dropdown when I select variation var1, the price shown below is ($75)striked off then $60 where as it should show $50. For all the variations when changed from var1 to var4, everytime it shows ($75)striked off then $60.

That is the main issue.

If don’t use “woocommerce_get_price_html” and use “woocommerce_variable_price_html” and “woocommerce_dropdown_variation_attribute_options_html” for variable products and “woocommerce_single_price_html” for Simple products, Simple product price formatting remains unchanged in Category Page, Shop Page, Search result and other pages where products appears in loop.

I am trying various examples posted in various forums including stackoverflow too, has no luck.

I will be great full if someone can provide any solution to solve the issue.

I am doing all this by creating a plugin for this purpose only.
