Wordpress echo a variable from a function that is inside a class

Hi There,

I have created a class which hold multiple functions. One of the function gets all the details about the author of a custom post type. I am trying to display the variables from this function in my author template.

Below is the code for my class that is in the functions.php

class pc_npPosts
{

function pc_get_np_info(){

       $pc_np_author_id    = get_query_var( 'author' );
        $pc_np_name = get_field('np_organization_name', 'user_'.  $pc_np_author_id);
        $pc_np_bio  = apply_filters('avf_author_description', get_the_author_meta('description',  $pc_np_author_id),  $pc_np_author_id);
        $pc_np_whatWeDo = get_field('np_what_we_do', 'user_'.  $pc_np_author_id);
        $np_organization_logo = get_field( 'np_organization_logo', 'user_'. $pc_np_author_id  ); 
        $np_profile_link = get_author_posts_url($pc_np_author_id);
        $np_organization_address = get_field( 'np_organization_address', 'user_'. $pc_np_author_id  ); 
        $np_organization_city = get_field( 'np_organization_city', 'user_'. $pc_np_author_id  ); 
        $np_organization_state = get_field( 'np_organization_state', 'user_'. $pc_np_author_id  );
        $np_organization_zipcode = get_field( 'np_organization_zipcode', 'user_'. $pc_np_author_id  );  
        $np_causes_interests = get_field( 'np_causes_interests', 'user_'. $pc_np_author_id );
}


}

Open in new window

I would like to display the above variable in author template like below

 $pc_np_author = New pc_npPosts;

 echo $pc_np_class->pc_get_np_info('pc_np_name');

Open in new window

but nothing displays. What am I missing or doing wrong.

Thanks

Do you have to return it instead or echo?

Hi Robert,

Thanks for replying. Appreciate it.

I am basically looking to display value of that variable on the template so it can be viewed on the webpage

Hi there,

All the values you're setting are locked away inside a method, so they're never going to be accessible - you need to move them outside of your method, so they become properties of the class :

class pc_npPosts
{
        $pc_np_author_id    = get_query_var( 'author' );
        $pc_np_name = get_field('np_organization_name', 'user_'.  $pc_np_author_id);
        $pc_np_bio  = apply_filters('avf_author_description', get_the_author_meta('description',  $pc_np_author_id),  $pc_np_author_id);
        $pc_np_whatWeDo = get_field('np_what_we_do', 'user_'.  $pc_np_author_id);
        $np_organization_logo = get_field( 'np_organization_logo', 'user_'. $pc_np_author_id  ); 
        $np_profile_link = get_author_posts_url($pc_np_author_id);
        $np_organization_address = get_field( 'np_organization_address', 'user_'. $pc_np_author_id  ); 
        $np_organization_city = get_field( 'np_organization_city', 'user_'. $pc_np_author_id  ); 
        $np_organization_state = get_field( 'np_organization_state', 'user_'. $pc_np_author_id  );
        $np_organization_zipcode = get_field( 'np_organization_zipcode', 'user_'. $pc_np_author_id  );  
        $np_causes_interests = get_field( 'np_causes_interests', 'user_'. $pc_np_author_id );
}

Open in new window

Now they're accessible as properties so you can echo them out:

$posts = new pc_npPosts();
echo $posts->pc_np_author_id;
echo $posts->$np_organization_logo;

Open in new window

Depending on your needs, there's probably a much more efficient way of doing this. As it stands, everytime you instantiate the class, you're call all those get_field() methods, whether you need them or not.

Thank you for both replying. I changed my class according to what gr8gonzo said. I do have one question,

Is it possible to pass the author_id dynamically based on where the function is being called. What I mean is for example I am trying to display author details on a each post page of the author. So I would like to pass the post id of the author to get the details of the author

basically

$this->pc_np_author_id needs to be changed dynamically

Thanks again
