How to show a single Item in cakePHP - php

Question

I am using cake PHP and on my view/technical_slider/index.ctp is the following:
I am using a heavily modified version of this tutorial Featured Content Slider Using jQuery
<?php foreach ($technicalSlides as $technicalSlide):?>
<div id="nav-fragment-1" class="ui-tabs-panel">
<h2><?php echo $technicalSlide['TechnicalSlide']['title'];?></h2>
<p><?php echo $technicalSlide['TechnicalSlide']['description'] ; ?></p>
</div>
<?php endforeach; ?>
My question is: How can I display only certain id's or items and apply different class on the same div ? Because I only want record 1-3 skip 4-7 then show record 8-15?
I am applying different classes on them because they have different backgrounds, but share the same id.

Answer 1

You coud add a counter and then display only those you want.
<?php int $i = 0; ?>
<?php foreach ($technicalSlides as $technicalSlide):?>
<?php if ($i < 4 || $i > 7): ?>
<div id="nav-fragment-1" class="ui-tabs-panel">
<h2><?php echo $technicalSlide['TechnicalSlide']['title'];?></h2>
<p><?php echo $technicalSlide['TechnicalSlide']['description'] ; ?></p>
<?php endif; ?>
</div>
<?php endforeach; ?>
Although I would merge all classes and use attributes.

Answer 2

Add a counter variable (in this case $i), increment it ($i++) so it increases by one for every loop, and add your checks to an if() block to make sure you only write the ones you want to:
<?php
$i = 1;
foreach ($technicalSlides as $technicalSlide):
if($i < 4 || $i > 7) {
?>
<div id="nav-fragment-1" class="ui-tabs-panel">
<h2><?php echo $technicalSlide['TechnicalSlide']['title'];?></h2>
<p><?php echo $technicalSlide['TechnicalSlide']['description'] ; ?></p>
</div>
<?php
}
$i++;
endforeach;
?>
