Display a custom field above product price in Woocommerce single product pages

In Woocommerce I have set a custom field in backed edit product pages in a correct way… Now I am trying to display a product this custom field value, before product price into a single product pages.

But for some reason, with the code below I can get it displayed (and the product price neither):

function bd_rrp_price_html( $price, $product ) {

    echo get_post_meta( $post->ID, '_text_field', true );

}
add_filter( 'woocommerce_get_price_html', 'bd_rrp_price_html', 100, 2 );

Any help is appreciated

This is what I want visually to be displayed:

Updated (2 alternatives)

Try instead the following revisited code:

add_filter( 'woocommerce_get_price_html', 'custom_single_price_html', 100, 2 );
function custom_single_price_html( $price, $product ) {
    $custom_field = get_post_meta( $product->get_id(), '_text_field', true );
    if ( is_product() && ! empty($custom_field) )
        $price = '<span class="custom-textfield">' . $custom_field . '</span><br>' . $price;
    return $price;
}

Code goes in function.php file of your active child theme (or active theme). Tested and works.

Or alternatively you can also use the following:

add_filter( 'woocommerce_single_product_summary', 'single_product_text_field', 8 );
function single_product_text_field() {
    global $product;

    $custom_field = get_post_meta( $product->get_id(), '_text_field', true );
    if ( ! empty($custom_field) )
        echo '<p class="custom-textfield">' . $custom_field . '</p>';
}
