Display normal price or variable price range in Woocommerce

I've a list of products and I've a problem about displaying the range of prices in variable products.

As you can see if the price is a normal price everything works. Nevertheless if the product has a variable price the price displayed is 0€

Well, the code for displaying price is this:

<?php
if (isset($ebookstore_theme_option['woo-list-price']) && 
    $ebookstore_theme_option['woo-list-price'] == 'enable') {
    $ebookstore_woo .= '<strong class="amount">'.esc_attr($currency).''.$price_sale.'</strong>';
}

Any idea about how to display the variable range price?

Solution

For a variable product in WooCommerce you need:

to target variable product type
to get the min and the max prices.

So you should need to get an instance of the product object. In general you can get it with:

 global $product;

If it doesn't work you will use intead:

global $post;
$product = wc_get_product( $post->ID );

Now from this point you will use the following:

<?php
global $product;

if ( isset( $ebookstore_theme_option['woo-list-price'] ) && $ebookstore_theme_option['woo-list-price'] == 'enable' ){

    // For all product types that are not "variable products"
    if( ! $product->is_type('variable') ){
        $ebookstore_woo .= '<strong class="amount">'.esc_attr($currency).''.$price_sale.'</strong>';
    }
    // For variable products    
    else {
        $min_price = $product->get_variation_price( 'min' );
        $max_price = $product->get_variation_price( 'max' );

        $ebookstore_woo .= '<strong class="amount">'.esc_attr($currency).''.$min_price.' - '.esc_attr($currency).''.$max_price.'</strong>';
    }
}

As you can see I am using the WC_Product_Variable methods

May be you don't know, but woocommerce has several formatting price functions as:

wc_price( $price );
wc_format_price_range( $from, $to );
wc_format_sale_price( $regular_price, $sale_price );

They will all include the currency
