The problem
I was working to create a system that allowed users to submit a Gravity Form entry with multiple file attachments that would create a post on the front end, printing those attachments. GF and the wonderful Gravity Forms + Custom Post Types plugin makes it easy to map a form field to a custom meta field (new or existing) – however I ran into a snag when trying to display multiple file uploads. Simply echoing get_post_meta was just returning one of the meta field values, not each value.
The answer
Create a simple loop that stores each of the meta values to a variable, then loop through each echoing out the file links. This loop will need to be added to the post content either via theme template, filtering the_content(), and adding it onto a hook. With this particular project using Genesis, I added it to the genesis_entry_content hook.
[php]
<?php $bulletin_files = get_post_meta( get_the_ID(), ‘bulletin_file_upload’ );
if ( $bulletin_files ) : ?>
<div><ul>
<?php foreach( $bulletin_files as $url ) { ?>
<li><a href="<?php echo $url; ?>">
<?php echo basename($url ); ?>
</a></li>
<?php } ?>
</ul></div>
<?php endif; ?>
[/php]
A really cool function used in the snippet above is basename(). It’s a simple php function that takes a string for a file path (in this case a url) and just grabs that filename at the end of the string. Pretty cool and way simpler than some regex solution.
