Hi everyone,

Is it possible to check if the field is not empty to just append new data?

Here is my code:
if ($product_id == 1126) {
$e_post = get_page_by_title($title, OBJECT, ‘company’);
$epost_id = $e_post->ID;
$member = wp_get_current_user();
$newmember = $member->ID;
//condition here to accept or append new member
update_field( ‘comp_members’, $newmember, $epost_id);
echo “Welcome, $title member.”;
} // End of new member

Where ACF ‘comp_members’ field can accept multiple User IDs.
Note: append new member data not replace.

This seems to be working now. by using

add_row( $selector, $value, $post_id );

in place of:

update_field($selector, $value, $post_id);
