php - Related Products ACF WordPress -


i not using woocommerce plugin, normal site.

i have page, need let user select 'related products'.

now, using acf, , looking @ using post_object allow user select product.

what needs do, product name, products image , description.

i have used code, acf site, attempt grab post object title.

    <?php  $post_object = get_field('post_object');  if( $post_object ):       // override $post     $post = $post_object;     setup_postdata( $post );       ?>     <div>         <h3><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>         <span>post object custom field: <?php the_field('field_name'); ?></span>     </div>     <?php wp_reset_postdata(); // important - reset $post object rest of page works correctly ?> <?php endif; ?>

but won't display anything?

is there obvious issues can see?

since allowing multiple selections, get_field return array of post objects. need loop through array, using following code. code assumes post object field named 'related_products', , calls post's excerpt value, check excerpt field first, , if not present, generate excerpt content of post.

    $related_products = get_field('related_products');      if( $related_products ): ?>             <ul>             <?php foreach( $related_products $post): // variable must called $post (important) ?>                     <?php setup_postdata($post); ?>                     <li>                             <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>                             <?php the_excerpt(); ?>                     </li>             <?php endforeach; ?>             </ul>             <?php wp_reset_postdata(); // important - reset $post object rest of page works correctly ?>     <?php endif;

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
