Hello, I need a little help, I would greatly appreciate if someone helped me with this. I have 3 functions, and I want to make them work the following way: Function 1: This function gives me a list of users who liked a blog post. It gives me an HTML list. I want a formula which filters the output giving me ONLY the first value of the list. Or only the second value. Or only the third value. the_users_who_favorited_post($post_id = null, $site_id = null, $separator = 'list', $include_anonymous = true, $anonymous_label = 'Anonymous Users', $anonymous_label_single = 'Anonymous User'); Example of output: John Albert Mary I want to filter the list and obtain only the first value: John. Or obtain only the second: Albert Function 2: This function gives me the ID of the user. And I need to bring the value from the Function 1 and insert in this functon 2: <?php $user = get_userdatabylogin('value from function 1 here'); if($user){ echo $user->ID; } ?> The output from function 1 goes "value from function 1 here". And it will give me the ID. Function 3: This code will give me the user avatar, from the ID i obtain from function 2. <?php echo get_avatar( ID goes here , '100' ); ?> The output from function 2 goes "ID goes here". And it will give me the profile avatar picture. I need to join these formulas together, and make them work. Does anyone know how to do this? Thanks.
