Displaying image captions

Hello again!

I wonder if anyone can help me with this.
It seems like a simple thing to do, but I’ve been trying for hours now, and couldn’t get it to work.

My custom post type is called ‘art’, and it has a ‘File / Image / Video’ custom field, where I can upload a single image file.
I managed to get the attachment ID, and the image alt text, but I wasn’t able to find how to get the image caption and/or description.

This is the code so far (in single-art.php) :
```
$art = pods('art', get_the_id());
$a_id = $art->field('ID');

$img = get_post_meta( $a_id, 'a_img._src.full', true);
$img_id = $art->field('a_img.ID', true);
$img_alt = get_post_meta($img_id, '_wp_attachment_image_alt', true);
$img_caption = get_post_meta($img_id, 'post_excerpt', true);

echo '<img src="' . $img . '" Alt="' . $img_alt . '" />';
echo '<p>' . $img_caption . '</p>';
```
Any help will be much appreciated.
Thank you!!

Actually, the Image Caption isn’t a meta field, it’s a standard post field for the post type media. When you create a File/Image/Video upload, you’re creating a relationship to the Media Library.

Once you create the link from the ID of the media, you should be able to get to your caption through $img_id->post_excerpt or $img_id->field('post-excerpt'). Likewise for the description, you’re going after the content through $img_id->post_content or $img_id->field('post-content').

Let me know if that works!

Thanks for your answer!

I tried $img_id->post_excerpt, but nothing happens.

And if I use this code: $img_id->field('post-excerpt')
I get the following error: Call to a member function field() on a non-object

Am I missing something?

Gotta love object based programming, huh?

We may need to step back up one level to get into the actual ‘object’ reference of that image.

Is a_img the field name in art that contains the reference to that particular image?

I’m not sure what you mean, I’m not very good at programming. Just trial and error.

echo $img; displays the image URL correctly.
echo $img_id displays the image ID correctly.

Does that answer your question?

Got it!
Here’s the code I used for image caption:
$img_caption = $art->field('a_img.post_excerpt', true);

Thank you so much for putting me on the right track!!
