      I want to add 2 image on a custom post. One of them, i have added with the WordPress feature, the other, i´m trying to add with Piklist but is not possible.
      I have been reading in this forum and trying the solution, but i cant fix it.

      This is my code in the custom-metabox.php:

      piklist('field', array(
  'type' => 'file'
  ,'field' => 'sec_img'
  ,'label' => 'Imagen secundaria'
));

      And this, in my single.php:

       <?php

                                      $image_ids = get_post_meta($post_id, 'img_sec');

                                      foreach ($image_ids as $image)
                                      {
                                        $myupload = get_post_meta($image);

                                        echo '<img src="' . wp_get_attachment_url($image) . '"/>';

                                        print_r($myupload); // Displays all data
                                      }
                                    ?>

      And I obtain this error in frontend:

      “Warning: Invalid argument supplied for foreach() in D:\xampp\htdocs\wordpress\wp-content\themes\MyBlog\single.php on line 55”

      And, no image is shown.

      Thanks!!

      I believe the file field stores it as a serialized single row. Try:
      $image_ids = get_post_meta($post_id, 'img_sec', true);

      Since you’re already using print_r, I suggest using that on $image_ids to help you know the structure of what you’re dealing with.

      Hope this helps! 🙂

      Solved:

      It was wrong: $image_ids = get_post_meta($post_id, 'sec_img', true);

      The correct form is: $image_ids = get_post_meta($post->ID, 'sec_img', true);

      So, my final code, to show the second image with Piklist, is:

      <?php

$image_ids = get_post_meta($post->ID, 'sec_img');
foreach ($image_ids as $image)
{
$myupload = get_post_meta($image);
echo '<img src="' . wp_get_attachment_url($image) . '"/>';
}
?>

      Thanks for your help!!
