Add brand to product tile

Hi, now we have the title on a single page made like this:

Product Attribute (producer) + Product Title

We would like to replace the producer attribute to brand and maintain the display style. Also remove additional brand displaying in different place on single page.

How can we do that ?

This is our current funcion:

remove_action( ‘woocommerce_single_product_summary’, ‘woocommerce_template_single_title’, 5 );
add_action( ‘woocommerce_single_product_summary’, ‘custom_template_single_title’, 5 );
function custom_template_single_title() {
global $product;
global $post;

$brand_name = $product->get_attribute(‘pa_producent’);
$rocznik = $product->get_attribute(‘pa_rocznik’);
$kraj = $product->get_attribute(‘pa_kraj’);
if( $brand_name ) {
$attribute_names = array( ‘pa_producent’);
echo ‘<h1 class=”product_title entry-title”><span class=”head-producent”>’;
foreach ( $attribute_names as $attribute_name ) {
$taxonomy = get_taxonomy( $attribute_name );

if ( $taxonomy && ! is_wp_error( $taxonomy ) ) {
$terms = wp_get_post_terms( $post->ID, $attribute_name );
$terms_array = array();

if ( ! empty( $terms ) ) {
foreach ( $terms as $term ) {
$archive_link = get_term_link( $term->slug, $attribute_name );
$full_line = ‘‘. $term->name . ‘‘;
array_push( $terms_array, $full_line );
}

echo $taxonomy = implode( $terms_array, ‘, ‘ );
}
}
}
echo ‘</span> ‘; }
else {
echo ‘<h1 class=”product_title entry-title”>’; }
the_title();
echo ‘</h1>’;
echo ‘<h5>’;
if( $rocznik ) {
echo ‘<i class=”fad fa-seedling”></i> ‘ . $rocznik . ‘ ‘; }
if( $kraj ) {
$attribute_names = array( ‘pa_kraj’);
echo ‘<i class=”fad fa-globe-europe”></i> ‘;
foreach ( $attribute_names as $attribute_name ) {
$taxonomy = get_taxonomy( $attribute_name );

if ( $taxonomy && ! is_wp_error( $taxonomy ) ) {
$terms = wp_get_post_terms( $post->ID, $attribute_name );
$terms_array = array();

if ( ! empty( $terms ) ) {
foreach ( $terms as $term ) {
$archive_link = get_term_link( $term->slug, $attribute_name );
$full_line = ‘‘. $term->name . ‘‘;
array_push( $terms_array, $full_line );
}

echo $taxonomy = implode( $terms_array, ‘, ‘ );
}
}
}
echo ”;

}
echo ‘</h5>’;
}
