How can I limit this custom function to update ONLY the custom post type?

This thread is resolved. Here is a description of the problem and solution.

Problem:

The issue here is that the user had some custom code for his archive but wanted it to be limited to a specific CPT.

Solution:

This can be done by using a simple if statement in PHP.

I've got the following code in my functions.php which pulls some custom fields out of an Events post type and prepends them to the exerpt of the RSS feed.

Problem is that the functions works on ALL feeds whereas I really only want it to apply to the Archive feed for the Events post type.

How can I add a conditional to check for the post type?

// Additional RSS Content
$rss_more_content = '';
$rss_more_position = 'before'; // or "after"

// Function which adds content to RSS entries
function add_rss_content($content) {
	global $rss_more_position, $rss_more_content, $post;
	
	$metaValue1 = get_post_meta($post->ID, 'wpcf-start-date', true);
    if(!empty($metaValue1)):
        $metaDate1 = date("Y m d", $metaValue1);
    endif;
    $metaValue2 = get_post_meta($post->ID, 'wpcf-end-date', true);
    if(!empty($metaValue2)):
        $metaDate2 = date("Y m d", $metaValue2);
    endif;

	if(is_feed()) {
		if ($rss_more_position == 'before') {
			$content = "<p>$rss_more_content <b>$metaDate1</b> -> <b>$metaDate2</b></p>\n$content";
		} else {
			$content .= "<p>$rss_more_content <b>$metaDate1</b> -> <b>$metaDate2</b></p>\n";
		}
	}
	return $content;
}

// Add hooks
add_filter('the_excerpt_rss', 'add_rss_content');

Hi Paul,

This should help


// Additional RSS Content
$rss_more_content = '';
$rss_more_position = 'before'; // or "after"
 
// Function which adds content to RSS entries
function add_rss_content($content) {
    global $rss_more_position, $rss_more_content, $post;
     
    $metaValue1 = get_post_meta($post->ID, 'wpcf-start-date', true);
$post_type = get_post_type($post->ID);
if ($post_type='my-cpt-slug'){
    if(!empty($metaValue1)):
        $metaDate1 = date("Y m d", $metaValue1);
    endif;
    $metaValue2 = get_post_meta($post->ID, 'wpcf-end-date', true);
    if(!empty($metaValue2)):
        $metaDate2 = date("Y m d", $metaValue2);
    endif;
 
    if(is_feed()) {
        if ($rss_more_position == 'before') {
            $content = "<p>$rss_more_content <b>$metaDate1</b> -> <b>$metaDate2</b></p>\n$content";
        } else {
            $content .= "<p>$rss_more_content <b>$metaDate1</b> -> <b>$metaDate2</b></p>\n";
        }
    }
}
    return $content;
}
 
// Add hooks
add_filter('the_excerpt_rss', 'add_rss_content');

Please let me know if this helps.
Thanks,

Close enough.

This is the final working code.

// Additional RSS Content
$rss_more_content = '';
$rss_more_position = 'before'; // or "after"
  
// Function which adds content to RSS entries
function add_rss_content($content) {
  global $rss_more_position, $rss_more_content, $post;
     
  $post_type = get_post_type($post->ID);
  
  if ($post_type=='event'){

  	$metaValue1 = get_post_meta($post->ID, 'wpcf-start-date', true);
        if(!empty($metaValue1)):
           $metaDate1 = date("Y m d", $metaValue1);
        endif;
       $metaValue2 = get_post_meta($post->ID, 'wpcf-end-date', true);
        if(!empty($metaValue2)):
           $metaDate2 = date("Y m d", $metaValue2);
        endif;
  
        if(is_feed()) {
           if ($rss_more_position == 'before') {
               $content = "<p>$rss_more_content <b>$metaDate1</b> -> <b>$metaDate2</b></p>\n$content";
           } else {
               $content .= "<p>$rss_more_content <b>$metaDate1</b> -> <b>$metaDate2</b></p>\n";
           }

       }

    }
    return $content;
}
  
// Add hook
add_filter('the_excerpt_rss', 'add_rss_content');

There was a small syntax error in your code.
Should be:

($post_type=='event')

not

($post_type='event')
