drawing URL from within LOOP

I really want to use this plugin but I can’t do the simplest thing.

What I want to do is just call out the URL to a single attachment to drop it into the href of a link for the user to download.

Actually, I’m not sure if that’s the right way to allow the user to download an attachment, but basically, right now I have no idea how to access the contents of the attachments array.

When I use the “exists” function, it returns the count of attachments. This seems fine.
When I use the “get” function, I get an array that houses the info about the attachment I loaded. Things seem to be working fine, I just can’t pull the contents from within the loop.

Code:
```
// Check for attachments… or count them??
$attachments_yes_no = wpba_attachments_exist(array(
    'post_id'             => $post->ID,
    'show_post_thumbnail' => true
));

// Get attachments
$about_attachments = wpba_get_attachments(array(
    'post_id'             => $post->ID,
    'show_post_thumbnail' => true
));
```
Results of array prints:

Any attachments?

1

Attachments Array print:

Array ( [0] => WP_Post Object ( [ID] => 113 [post_author] => 1 [post_date] => 2014-01-11 06:24:33 [post_date_gmt] => 2014-01-11 06:24:33 [post_content] => This is a sample contract acting as a filler file.

Your almost there the only thing your really missing is a loop and wp_get_attachment_url(). Here is one way I would do it there may be other ways possibly use a custom WP_Query instead of wpba_get_attachments() if you want more flexibility. Since they are actual WordPress attachments you can query them like any other post type.
```
<?php
// Get attachments
$about_attachments = wpba_get_attachments(array(
	'post_id'             => $post->ID,
	'show_post_thumbnail' => true
));

foreach ( $about_attachments as $attachment ) {
	$att_url   = wp_get_attachment_url( $attachment->ID );
	$att_title = $attachment->post_title;
	// For a title you could also use something like this if you want the filename
	// I have not tested this so it may need to be tweaked.
	// $upload_dir = wp_upload_dir( 'yyyy/mm' );
	// $att_title  = str_replace( $upload_dir, '', $att_url );
	?>
	<a href="<?php echo esc_url( $att_url );  ?>"><?php echo esc_html( $att_title ); ?></a>
<?php } // foreach
```
Please let me know if this does not answer your question.

Hey! Thanks for getting back so quickly. This looks like a good solution. I’ll post again after I try it.

Thank you Thank you Thank you!!

I guess I’m still getting familiar with theming with WordPress overall. I wasn’t aware of the “wp_get_attachment_url()” function.

I could do exactly what I want by targeting the first item in the array and dropping the url into an href.
```
// Get attachments
$about_attachments = wpba_get_attachments(array(
    'post_id'             => $post->ID,
    'show_post_thumbnail' => true
));
// get URL
$resume_url = wp_get_attachment_url($about_attachments[0]->ID);

<p><a href="<?php echo $resume_url; ?>">See my resume</a></p>
```
Thanks again. This plugin is a lot more approachable than the more robust alternative “Attachments.” A couple more examples in the documentation or concepts to study (such as this wp_get_attachment_url() function and its brethren), and I think it will be easier to pick up for novices like myself.

Oops, I forgot to mark this as resolved.

Thanks again. You rock, dholloran!
