the_sub_field is returning unwanted information

Spent a few hours trying different solutions but I can’t figure out why the_sub_field is returning all sorts of unwanted info, when I only want the attachment file name.

Here is my code:

<?php 

		// check if the repeater field has rows of data
		if( have_rows('attachments') ):

		 	// loop through the rows of data
		    while ( have_rows('attachments') ) : the_row();

		        // display a sub field value
		        $file = get_sub_field('file_attachment');
		        if( $file ):
		        ?>
		        
		        <a target="_blank" href="<?php echo $file['url']; ?>"><?php the_sub_field('file_attachment'); ?></a>
		        
		        <?php endif;

		    endwhile;

		else :

		    // no rows found

		endif;

	?>

See attachments for reference to the admin settings and front-end display. Any ideas why this is happening and how to just return the file name or url (ex. document.pdf)

the_sub_field('file_attachment') gets the same thing that get_sub_field('file_attachment'); returns. The only difference is that the_sub_field() echos the value, in this case a stringified array, and get_sub_field() returns the array. If you want to echo the file name then you need to echo the title array element, or one of the other array elements for other things

<?php 

		// check if the repeater field has rows of data
		if( have_rows('attachments') ):

		 	// loop through the rows of data
		    while ( have_rows('attachments') ) : the_row();

		        // display a sub field value
		        $file = get_sub_field('file_attachment');
		        if( $file ):
		        ?>
		        
		        <a target="_blank" href="<?php echo $file['url']; ?>"><?php echo $file['title']; ?></a>
		        
		        <?php endif;

		    endwhile;

		else :

		    // no rows found

		endif;

	?>

Thanks, John. Where can I get a list of possible array elements?

That’s a good question, I don’t know. This is the information that’s available and what I looked at https://www.advancedcustomfields.com/resources/file/

What I would do is this to output the array so I can see what’s in it.

$file = get_sub_field('file_attachment');
echo '<pre>'; print_r($file); echo '</pre>';

That output array is actually perfect. Thanks a ton!
