Greetings. Thank you for the awesome product! I <3 ACF so much!
Here’s what I’m trying to do. I have a Zoo website I’m working on and the animals have a custom post type that I’m using. The animals use the Title for their name but I also have the scientific name as an ACF field. What I want to do is have the Title of the page be the Animal name – Scientific name – Site Name. I see Yoast SEO uses %%title%% and %%sitename%% and that it can call in custom fields with %%cf_<field name>%% but I just didn’t see a way for me to be able to call in ACF fields similar to the %%cf_<field name>%%. Is this possible or do I need to just hard code it into the header.php file? I was hoping to do it the former to both automate it and allow the client to see it on the back end editor.
Thank you again,
Jeremy
You should be able to replace `<field_name>’ with the name you’ve given the field that holds the scientific name.
for example, if you’ve name the field scientific_name then enter %%cf_scientific_name%% into the title template field for the post type.
Following on from this, I have a Post Object as my custom field that I want to retrieve the title from. Using cf_field_name will only return the ID of that Post Object – what do I have to do to lookup that post and add the title from that post as a custom field which is available to Yoast?
Any ideas?
Thanks,
@lucpestille for that I think you would need to use the SEO hook for modifying the post title, but you’ll need to do a bit more checking
add_filter('wpseo_title', 'change_seo_title');
function change_seo_title($string) {
$queried_object = get_queried_object();
if (!isset($queried_object->ID ||
get_post_type($queried_object->ID) != 'your-post-type-here')) {
// bail early
return $string;
}
$related_post = get_field('post_object_field_name', $queried_object->ID);
if ($related_post) {
$title = get_the_title($related_post->ID);
$string .= ' - '.$title;
}
return $title;
}
Excellent – worked almost straight out of the box – thanks a million. For anyone else who needs it, my final code was;
function change_seo_title($string) {
$queried_object = get_queried_object();
if ( !isset($queried_object->ID) || get_post_type($queried_object->ID) != 'post' ) {
// bail early
return $string;
}
$related_post = get_field('product', $queried_object->ID);
if ($related_post) {
$related_post_title = get_the_title($related_post->ID);
$new_title = $related_post_title . " - " . $string;
}
return $new_title;
}
add_filter('wpseo_title', 'change_seo_title');
How will these and other YoastSEO related approaches work out when Yoast releases their new version of the plugin, somewhere in November. They are going to remove a lot of filters in favour of faster page analysis, one of these is the ‘wpseo_pre_analysis_post_content’ filter and that one is used by a lot of ACF developers.
Can someone from the ACF team comment on this?
This is what Yoast is going to do:

I’m trying to use this but custom post type still showing ID instead of title.
Any suggestion or help ????
