I'd like to create a WooCommerce products widget like the standard WooCommerce products widget, but with the option to filter on category. I know there is a shortcode for displaying products of a certain category, but I don't like the standard thumbnail view, but like to have a list like in the WooCom products widget.
On Github, I have found the following code which allows to add a WooCom products widget with a filter on product ID:
<?php
/*
Plugin Name: Woocommerce Custom Widget Product

*/
if ( ! defined( 'ABSPATH' ) ) exit; // Exit if accessed directly
class Bi_Widget_Product extends WP_Widget
{
function __construct()
{
parent::__construct(
'woocommerce_ndbProducts',
__( 'WP Customs Products', 'ndb' ),
array('description' => __( 'This plugin help display a list of customs products on your website.', 'ndb' ))
);
}
public function widget( $args, $instance ) {
extract( $args );
$title = apply_filters( 'widget_title', $instance['title']);
$ids = $instance['ids'];
$arr_id = explode(',',$ids);
$query_args = array(
'post_status' => 'publish',
'post_type' => 'product',
'no_found_rows' => 1,
'post__in' => $arr_id
);
$r = new WP_Query( $query_args );
if ( $r->have_posts() ) {
echo $before_widget;
if ( $title )
echo $before_title . $title . $after_title;
echo '<ul class="product_list_widget">';
while ( $r->have_posts()) {
$r->the_post();
global $product;
?>
<li>
<a href="<?php echo esc_url( get_permalink( $product->id ) ); ?>" title="<?php echo esc_attr( $product->get_title() ); ?>">
<?php echo $product->get_image(); ?>
<?php echo $product->get_title(); ?>
</a>
<?php if ( ! empty( $show_rating ) ) echo $product->get_rating_html(); ?>
<?php echo $product->get_price_html(); ?>
</li>
<?php
}
echo '</ul>';
echo $after_widget;
}
wp_reset_postdata();
echo $content;
}
// Widget Backend
public function form($instance){
$title = (isset($instance['title'])) ? $instance['title'] : __( 'Products', 'ndb' );
$ids = $instance['ids'];
?>
<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 ); ?>" />

<?php
}
public function update( $new_instance, $old_instance ) {
$instance = array();
$instance['title'] = ( ! empty( $new_instance['title'] ) ) ? strip_tags( $new_instance['title'] ) : '';
$instance['ids'] = ( ! empty( $new_instance['ids'] ) ) ? strip_tags( $new_instance['ids'] ) : '';
return $instance;
}
}
add_action( 'widgets_init', function(){
register_widget( 'Bi_Widget_Product' );
} );
Can any of you Wordpress Guru's help me to adapt this so I can filter on category instead of product ID? I'll do an attempt myself, but definitely can use your help.
Own attempt: I think I should change my WP_query arguments to retrieve the category ID's instead of the post ID's. However, I tried this & this is not working.
$query_args = array(
'post_status' => 'publish',
'post_type' => 'product',
'no_found_rows' => 1,
'cat' => $'arr_id'
);
$r = new WP_Query( $query_args );
Full solution as provided by LWS-Mo Many many many thanks! You made my day. I would like to accept and upvote your comment but since I am new on the forum, my reputation is not high enough for that :(. Anyone else who is able to use the solution, give the man some credits ;). Again thanks!
