get_post_meta display

  • I have this code:

    [ Moderator Note: Please post code or markup snippets between backticks or use the code button. ]

    <?php
global $product, $woocommerce_loop;
$related_cats = get_post_meta($post->ID,'related_cat', true);
$related_cats = explode('|',$related_cats);
foreach ( $related_cats as $related_cat) {
echo '<div class="image-cat">
<a href="/?product_cat='.$related_cat.'"><img src="/wp-content/uploads/'.$related_cat.'.jpeg" alt="Related Cat1" width="200" height="200" /></a>

<p><a href="/?product_cat='.$related_cat.'">'.$related_cat = str_replace("-", " ",$related_cat).'</a></p>
</div>';
}
?>

    But if there is no $related_Cat then it still displays the div and blank image etc.

    I cant figure out how to re write this to only show the echo’d content if it actually exists.

    Try that.. you just have to check before continuing with the echo

    I had to make some tweaks to your code to get it working:

    <?php
global $post;

$related_cats = get_post_meta($post->ID,'related_cat', true);
$related_cats = explode('|',$related_cats);

foreach ( $related_cats as $related_cat) {

if($related_cat != NULL){

echo '<div class="image-cat">
<a href="/?product_cat='.$related_cat.'"><img src="/wp-content/uploads/'.$related_cat.'.jpeg" alt="Related Cat1" width="200" height="200" /></a>

<p><a href="/?product_cat='.$related_cat.'">'.$related_cat = str_replace("-", " ",$related_cat).'</a></p>
</div>';

}

}
?>

    But now works perfectly! Thanks for the help
