Display related products filtered by product attribute in Woocommerce












1














I want to display related products filtered by an attribute, that it should be equal to a value from page cookies.



I edit related.php template to look like that:



<?php woocommerce_product_loop_start(); ?>

<?php foreach ( $related_products as $related_product ) :
// extract attribute filter_location in an array
$results = $related_product->get_attribute( 'pa_filter_location' );

// extract value from cookies filter_location
$fl = $_COOKIE['filter_location'];

foreach ( $results as $key ) {
if( $key == $fl ) {
$post_object = get_post( $related_product->get_id() );

setup_postdata( $GLOBALS['post'] =& $post_object );

wc_get_template_part( 'content', 'product' );
}
}

endforeach; ?>

<?php woocommerce_product_loop_end(); ?>


But I get the error: Warning:




Invalid argument supplied for foreach()




What can be the problem?

          The problem comes from this line:



          $results = $related_product->get_attribute( 'pa_filter_location' );


          That is not giving an array, but a coma separated string of terms. So you can't use it in your foreach loop this way.



          Instead use the following revisited code:



          <?php woocommerce_product_loop_start(); ?>

          <?php foreach ( $related_products as $related_product ) :
          // extract attribute filter_location in an array
          $terms = $related_product->get_attribute( 'pa_filter_location' );

          // Set each term in an array
          $terms = ! empty($terms) ? (array) explode(', ', $terms) : array();

          foreach ( $terms as $term ) {
          if( isset($_COOKIE['filter_location']) && $term == $_COOKIE['filter_location'] ) {
          $post_object = get_post( $related_product->get_id() );

          setup_postdata( $GLOBALS['post'] =& $post_object );

          wc_get_template_part( 'content', 'product' );
          }
          }

          endforeach; ?>

          <?php woocommerce_product_loop_end(); ?>


          It should definitively solve your error related to the foreach loop.
