Hello I've been struggling for ages trying to find a solution for this. Basically I just want to retrieve all images from a post and display a caption underneath. Here is the code i'm using:

    <?php
$argsThumb = array(
    'order'          => 'DESC',
    'post_type'      => 'attachment',
    'post_parent'    => $post->ID,
    'post_mime_type' => 'image',
    'post_status'    => null
);
$attachments = get_posts($argsThumb);
if ($attachments) {
    foreach ($attachments as $attachment) {
        echo '<div class="slideshow-content"><img src="'.wp_get_attachment_url($attachment->ID, 'thumbnail', false, false).'" /><div class="captions"><p>'.apply_filters('the_title', $attachment->post_title).'</p></div></div>';
    }
}
?>

As you can see it currently displays the title, but not the caption. I have tried using: $caption = $attachment->post_excerpt; - but not exactly sure where to implement it and what I have tried doesn't work. Any help would be greatly appreciated!

Why $attachment->post_excert; doesn't work for you? –  Mamaduka Sep 23 '11 at 13:09

the following should just show the caption:

echo '<div class="slideshow-content"><img src="'.wp_get_attachment_url($attachment->ID, 'thumbnail', false, false).'" /><div class="captions">'.apply_filters('the_excerpt', $attachment->post_excerpt).'</div></div>';

(applying the excerpt filter adds the paragraph tag automatically)

Thanks Michael, that's fixed it. The only problem I have is that when first uploading an image and a caption is entered it displays fine. However, if upload without a caption & then edit the post and image caption, it won't display. Is there a fix for this? –  Tim Sep 23 '11 at 14:47
    
Actually, no worries I have solved it. Editing the caption from the gallery works, but not from within the post editor! –  Tim Sep 23 '11 at 14:57
    
There's no way to access the Post Editor for Attachment post-types. As far as I know, you have to use the Media Manager. The "caption" field correlates to $post->post_excerpt for the Attachment itself. The Post Editor applies to the excerpt for the Parent Post to which the images are attached. –  Chip Bennett Sep 23 '11 at 15:38
    
Of course - that's why it wasn't updating output! Thanks. –  Tim Sep 23 '11 at 16:26

In what context are you attempting to run this code?

If it's inside the Loop (e.g. within another Post), why not just use [gallery id="123"]?

If it's outside the Loop (or outside the Post content), why not use do_shortcode( 'gallery', $args )?

I'm running it inside the loop in single.php. I need to load images with <div class="slideshow-content"> wrapped around for a slideshow. Is this also possible with the method you mentioned? –  Tim Sep 23 '11 at 14:50
    
Is this slideshow going to appear in every Post, or just selected Posts. If only in selected Posts: how are you implementing the selection? –  Chip Bennett Sep 23 '11 at 15:37
    
Currently it is every post - as I am creating the theme to be used as a portfolio. However - I may separate it later by category - I'm assuming something like this would work? <?php if ( in_category( 'slideshow' )) { // do slideshow } else { // other } ?> –  Tim Sep 23 '11 at 16:21
