Cycle HelperΒΆ
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 $data) function
1 2 3 4 5 6 7 8 9 10 11 12 | <?php foreach ($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
1 2 3 4 5 6 | <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.
1 2 3 4 5 6 7 8 | <?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;?>
