Multiple custom field values in one

    Hey,

    New to WordPress, (and PHP) and I’m having some trouble with custom fields, hopefully you guys can help me with it.

    I’m trying to create a fancy-box image gallery with custom fields, but I can’t find info anywhere that shows me how to combine field values into one statement.

    For example, I have these two values:
    1) Thumbnail = image_thumb.jpg
    2) Full-size = image.jpg

    I’m using the following code:

    <?php
$image_path = wp_upload_dir();
$custom_path= $image_path['baseurl'].'/'.$post->post_name;;

?>
<?php $thumb = get_post_meta($post->ID, 'Thumbnail', false); ?>
<?php $full_size = get_post_meta($post->ID, 'Full_size', false); ?>
<?php foreach($thumb as $thumb) {
echo '<li><a class="zoom1" href="'.$custom_path.'/'.$full_size.'" rel=""/><img src="'.$custom_path.'/'.$thumb.'" /></a></li>';
} ?>

    It loops through each thumbnail key and shows the thumbnail image just fine, but puts the full-size image link as an array. (http://PATH/wp-content/uploads/POSTNAME/Array).

    Can someone please show me how I would add the full-size image in there so that the full line of code looks like this?:
    <li><a class="zoom1" href="http://PATH/wp-content/uploads/POSTNAME/full-size.jpg" rel="POSTNAME"/><img src="http://PATH/wp-content/uploads/POSTNAME/full-size.jpgthumb.jpg" /></a></li>

    If there is only one full_size image for the posts, I think you need to change this:

    <?php $full_size = get_post_meta($post->ID, 'Full_size', false); ?>

    to this:

    <?php $full_size = get_post_meta($post->ID, 'Full_size', true); ?>

    Thanks for the reply.
    I understand that, it’s the combining of two different custom fields that I can’t get.

    I need to pull 2 different custom fields into one foreach or while statement, but I can’t figure it out.

    Are you saying that there are multiple thumbs and multiple full_size for one post?

    If so, I don’t know of any way to match them up.

    If there are multiples, you might consider putting both the thumb and the full_size in one custom field separated by a comma and splitting them in the foreach loop. That way the pairs would always be together.
