Hello,

Im trying to add ACF image URL to my RSS feed with the following code in functions.php:

<?php
function fields_in_feed($content) {  
    if(is_feed()) {  
        $post_id = get_the_ID();  
		
		$output = '<acfTitle>' . get_post_meta($post_id, 'titel', true) . '</acfTitle>';  
        $output .= '<acfImage>' . get_post_field($post_id, 'img', true) . '</acfImage>';  
        $output .= '<acfText>' . get_post_meta($post_id, 'text', true) . '</acfText>';  
    }  
    return $output;  
}  
add_filter('the_content','fields_in_feed');
?>

The title and text returns just great but the img just output the width of the image. I want the URL of the image.

How do I accomplish this?

Hi @Dev

The problem is that you are using the get_post_meta function instead of the ACF get_field function.

Please refer to the image field docs on how to render the image URL

Thanks

i was trying to get acf content in general to show the text for items.
in the rss feed which i used in a mailchimp campagne it was only showing the title as a link to the item.

when i put the code above in the functions.php it seemed to work but the content of my pages (without acf fields, only the ‘content’) disappeared.

any thoughts?

o wait, thsi seems to work:

function fields_in_feed($content) {  
    if(is_feed()) {  
        $post_id = get_the_ID();  
        $output .= '<p>' . get_post_meta($post_id, "text", true) . '</p>';    
        $content = $content.$output;  
    }  
    return $content;  
}  
add_filter('the_content','fields_in_feed');
