    <p>Here is an example of putting the code into a class format which the direction I would go FYI, it may be useful to learn a bit more of the OOP practices for PHP (<a href="http://php.net/manual/en/language.oop5.php" rel="nofollow">http://php.net/manual/en/language.oop5.php</a>):</p> <pre><code>#1) Get the data you wish to pass into your function. $data = "TEST"; get_partners($data); #2) Call your function. function get_partners($atts) { //Extract using ($att) passed in from your call. //The shortcode_atts function should be accessible by the file containing this function. extract(shortcode_atts(array( 'ids' =&gt; null, 'extra_options' =&gt; 'something' //in wordpress I can read this value using local $extra_options ), $atts)); //Create a new class element that will build your data for your and allow you to pass in your variable on the fly. $p = new partners(); $p-&gt;extra_options= $atts; //Pass the variable here. $p-&gt;print_partners_scripts(); } #3) Define Class here. class partners { var $extra_options; public function print_partners_scripts() { $output = '&lt;script type="text/javascript"&gt;' . "\n"; $output .= 'jQuery(document).ready( function() {'. "\n"; $output .= ' $(".partners-slider").bxSlider({ slideWidth: 924, auto: 0, autoStart: 0, moveSlides: 1, minSlides: 3, maxSlides: 8, pager: false, controls: false, slideMargin: 5, ' . $this-&gt;extra_options . ' });' . "\n"; $output .= '});' . "\n"; $output .= '&lt;/script&gt;' . "\n"; $output .= $this-&gt;additional_data(); echo $output; } protected function additional_data() { add_action( 'wp_footer', 'print_partners_scripts' ); $ids; #Where is this defined? $ids = explode( ',', $ids ); $output = '&lt;div class="ps-wrap"&gt;&lt;div class="partners-slider"&gt;'; foreach($ids as $id) { $img_attr = wp_get_attachment_image_src( $id, 'full' ); $output .= '&lt;div class="pslide"&gt;&lt;img src="' . $img_attr[0] .

    1. COOOP may be beneficial (although it may be over-kill here), but this uses some pretty bad practices of its own: the `get_partners` function should be inside the class, possibly as a static function; it's still using `extract` unnecessarily; `var` should be replaced with `public`; and function names should generally be verbs, so `additional_data` should be `get_additional_data`, or preferably something more descriptive. Oh, and by "class element", I think you mean "instance".

    2. COIn this example the get_partners function would not be inside the class/instance as it is the function that creates the class/instance. Although it is true that some of its logic could be moved into the class/instances itself. Are you suggesting that the class be created outside of a function?

    3. COThat's why I suggested it be a *static* function, so you could run `Partners::get_partners($data)`. Or it could be the constructor of the class, so that you would run `$partners = new Partners($data); $partners->print_partners_scripts();`. Chances are, this would be inside some other function anyway, containing all the function calls needed on the page.

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.
