Hi,
iam trying to use a Post Object field within a function but i have no luck so far. Is it even possible and if yes how to do it?
Heres my example code:
If i call the function it outputs the Title of the actual site but not the post object. If i use the code outside of the function everything works fine.
Thanks a lot in advance for any help!
Michael
function example($field, $options) {
$post_object = get_field($field, $options);
if($post_object) {
# get post data
$post = $post_object;
setup_postdata($post);
?>
<h3><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>
<?php
# reset postdata
wp_reset_postdata();
}
}
Call of the function:
example('my_post_object', '');
I think you’ll have to pass along the current posts id as well (or use global $post)..
<?php
function example($field, $postID) {
$post_object = get_field($field, $postID);
if($post_object) {
# get post data
$post = $post_object;
setup_postdata($post);
?>
<h3><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>
<?php
# reset postdata
wp_reset_postdata();
}
}
example('my_post_object', $post->ID); //in your template, assuming you do this inside the loop. If outside try replacing $post->ID with get_the_ID()
?>
Hi guys.
@Jonathan – nice code, but I think you need to reference global $post within the function like so:
function example($field, $postID) {
global $post;
$post_object = get_field($field, $postID);
if($post_object) {
// get post data
$post = $post_object;
setup_postdata($post);
?>
<h3><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>
<?php
// reset postdata
wp_reset_postdata();
}
}
example('my_post_object', $post->ID); //in your template, assuming you do this inside the loop. If outside try replacing $post->ID with get_the_ID()
?>
@elliot wouldn’t that be redundant since we’re already passing along the current page/post id?
Hey Guys, thanks a lot the version with the global $post works just fine! Thanks!
Cheers,

Hi @Jonathan
the globla $post is needed for the setup_postdata function to work within a function.
Weird, I know.
Hi @elliot
Hah.. what do you know! That is indeed wierd..
