Cycle Helper

The Cycle helper is used to alternate a set of values.

Cycle Helper Basic Usage

To add elements to cycle just specify them in constructor or use assign(array $data) function

<?php foreach ($this->books as $book):?>
  <tr style="background-color:<?php echo $this->cycle(array("#F0F0F0",
                                                            "#FFFFFF"))
                                              ->next()?>">
  <td><?php echo $this->escapeHtml($book['author']) ?></td>
</tr>
<?php endforeach;?>

// Moving in backwards order and assign function
$this->cycle()->assign(array("#F0F0F0","#FFFFFF"));
$this->cycle()->prev();
?>

The output

<tr style="background-color:'#F0F0F0'">
   <td>First</td>
</tr>
<tr style="background-color:'#FFFFFF'">
   <td>Second</td>
</tr>

Working with two or more cycles

To use two cycles you have to specify the names of cycles. Just set second parameter in cycle method. $this->cycle(array("#F0F0F0","#FFFFFF"),'cycle2'). You can also use setName($name) function.

<?php foreach ($this->books as $book):?>
  <tr style="background-color:<?php echo $this->cycle(array("#F0F0F0",
                                                            "#FFFFFF"))
                                              ->next()?>">
  <td><?php echo $this->cycle(array(1,2,3),'number')->next()?></td>
  <td><?php echo $this->escapeHtml($book['author'])?></td>
</tr>
<?php endforeach;?>
