    <p>I am trying to work this function in wordpress theme the way where I can get value only what I want and not all to gather. I am not much familiar with using array in function so I need you expert help to make it works and I would really appreciate that.</p> <p>Here is my code</p> <pre><code>function gallery_artist($arg=null, $arg2=null, $arg3=null){ global $png_gallery_meta; $png_gallery_meta-&gt;the_meta(); $gallery = get_post_meta(get_the_ID(), $png_gallery_meta-&gt;get_the_id(), TRUE); $gallery_value = $gallery['image_artist']; $artist_info = $gallery_value; $string = $artist_info; $artist = substr($string, 0, stripos($string, "/") ); // getting first name and last name from user id $author_first_name = get_userdata(basename($string))-&gt;first_name; $author_last_name = get_userdata(basename($string))-&gt;last_name; $author_full_name = $author_first_name . ' ' . $author_last_name; $user_id = '&lt;a href=" ' . get_author_posts_url(basename($string)) . ' " title="more submissions of ' . $author_first_name .' '. $author_last_name . ' " &gt;' . $artist . '&lt;/a&gt;'; $arg = $author_first_name; echo $arg; $arg2 = $author_last_name; echo $arg2; $arg3 = $user_id; echo $arg3; } </code></pre> <p>After than I want to use this function to get any value I want and not unnecessary to render all three to gather. Means if I want only first name than I pass value only for that and it will render only first name so on..</p> <p>Here how I want to use something. but you can suggest any code and type of function I have no issue.</p> <pre><code>&lt;?php call_user_func_array('gallery_artist', array('first_name','last_name','artist_id') ) ?&gt; </code></pre> <p>Big Big thanks to you all..</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
