ACF Custom Widget on Woocommerce Shop Page (Repeater) - php

Question

I have a big issue with an ACF custom widget, I would like to setup a Repeater style using ACF Pro displayed in the Sidebar on the Shop page of WooCommerce platform. The problem is - it doesn't work. It doesn't display the image sub_field called "photoTest" in the page_sliders.
I downloaded the widget and tried to figure out this but I have no idea where is the problem.. ACF rule is linked with the widget, in the functions there is an absolute path to the custom widget but I think the problem might be with the custom widget itself so here is the code.
<?php
class ACF_Custom_Widget extends WP_Widget {
function __construct() {
parent::__construct(
'acf_custom_widget',
__('ACF Custom Widget', 'text_domain'),
array( 'description' => __( 'A custom ACF widget', 'text_domain' ), 'classname' => 'acf-custom-widget' ) // Args
);
}
public function widget( $args, $instance ) {
echo $args['before_widget'];
if ( !empty($instance['title']) ) {
echo $args['before_title'] . apply_filters( 'widget_title', $instance['title'] ). $args['after_title'];
}
echo get_field('title', 'widget_' . $args['widget_id']);?>
<?php
if ( is_shop() ){
$page_id = get_option( 'woocommerce_shop_page_id' );
}
else {
$page_id = get_the_ID();
}
if( have_rows('page_sliders', $page_id) ): ?>
<div id="carouselControls" class="carousel slide" data-ride="carousel">
<div class="carousel-inner">
<?php while( have_rows('page_sliders', $page_id) ): the_row();
// vars
$image = get_sub_field('photoTest', $page_id);
?>
<div class="photo-wrap">
<img src="<?php echo esc_url($image['url']); ?>" alt="<?php echo esc_attr($image['alt']); ?>" />
</div>
<?php endwhile; ?>
</div>
</div>
<?php endif; ?>
<?php
echo $args['after_widget'];
}
public function form( $instance ) {
if ( isset($instance['title']) ) {
$title = $instance['title'];
}
?>
<p>
<label for="<?php echo $this->get_field_id( 'title' ); ?>"><?php _e( 'Title' ); ?></label>
<input class="widefat" id="<?php echo $this->get_field_id( 'title' ); ?>" name="<?php echo $this->get_field_name( 'title' ); ?>" type="text" value="<?php echo esc_attr( $title ); ?>">
</p>
<?php
}
public function update( $new_instance, $old_instance ) {
$instance = array();
$instance['title'] = ( ! empty( $new_instance['title'] ) ) ? strip_tags( $new_instance['title'] ) : '';
return $instance;
}
}
add_action( 'widgets_init', function(){
register_widget( 'ACF_Custom_Widget' );
});
Please help..thank you.
