images are not shown

I’m a bit closer to the solution; in the admin environment, I wrote echo ("hello world"); into the function miu_get_images. This message is displayed in the interface, but when I write echo ($post_id);, the echo is not displayed…

I am using https://minimable.fedeweb.net, a single page interface (https://minimable.fedeweb.net/docs/index.html)

I ran into this same issue.

I was able to output photos by using the WordPress call get_post_meta. First check to see if there are images, then unserialize the array and strip out the quotations.

Then I just wrote a simple foreach loop to insert each one of my saved images into an image tag.

Paste the following within your WP loop and that should do the trick!

<?php if ( get_post_meta( get_the_ID(), 'miu_images', true ) ) : ?>
    <?php
    $array = unserialize(get_post_meta( get_the_ID(), 'miu_images', true ));
    $images = str_replace('"', "", $array);
    ?>
        <?php foreach( $images as $image ) : ?>

            <img class="thumb" src="<?php echo $image; ?>" alt="<?php the_title(); ?>" />

	<?php endforeach; ?>
<?php endif; ?>

<?php $images = miu_get_images($post_id); ?>

Above code just returns you array of images but not display images,. You can loop through $images to print images in any fashion.

To display images do like this.

<?php
$images = miu_get_images($post_id=null);
foreach ($images as $image):
    ?>
    <img src="<?php echo $image; ?>" alt="<?php the_title(); ?>" />
<?php endforeach; ?>

Note: $post_id is optional parameter, current post_id will be used if omitted.

Hi, Tahir!

I’m using your plugin and @ch6x code tip but I have a lightbox which I must call the original image size and the thumbnail size in a custom post type. With the <?php echo $image; ?>, I’ve got the original size, but I’m not having success with the thumbnail.

Can you help me?

Thanks!

<?php while ( have_posts() ) : the_post(); ?>
    <?php if ( is_single() ) : ?>

    <h2><?php the_title(); ?></h2>

    <ul>
      <?php if ( get_post_meta( get_the_ID(), 'miu_images', true ) ) : ?>
          <?php
          $array = unserialize(get_post_meta( get_the_ID(), 'miu_images', true ));
          $images = str_replace('"', "", $array);
          ?>

          <?php foreach( $images as $image ) : ?>

          <li>
          	<a class="open-lookbook" href="<?php echo $image; ?>" data-fancybox-group="gallery" title="Lorem ipsum dolor sit amet">
          		<img src="<?php echo $image; ?>" alt="" />
          	</a>
          </li>

          <?php endforeach; ?>
      <?php endif; ?>
    </ul>

    <?php endif; ?>
<?php endwhile; ?>

Currently the plugin is not using resized images for thumbnails, I am working on it and this will be part of next version.

For now you can resize images with CSS.

For example:

<img src="<?php echo $image; ?>" alt="<?php the_title()?>" class="thumbnail" />

and define class thumbnail in style.css or your theme.

or with inline CSS:

<img src="<?php echo $image; ?>" alt="<?php the_title()?>" style="width:100px;" />

Damn it!
It would be perfect for responsive grids, because I could use all the thumbnails with the same size.

Thanks anyway, Tahir!
