cycle

This ViewHelper cycles through the specified values. This can be often used to specify CSS classes for example. Note: To achieve the “zebra class” effect in a loop you can also use the “iteration” argument of the for ViewHelper.

= Examples =

<code title=”Simple”> <f:for each=”{0:1, 1:2, 2:3, 3:4}” as=”foo”><f:cycle values=”{0: ‘foo’, 1: ‘bar’, 2: ‘baz’}” as=”cycle”>{cycle}</f:cycle></f:for> </code> <output> foobarbazfoo </output>

<code title=”Alternating CSS class”> <ul>

<f:for each=”{0:1, 1:2, 2:3, 3:4}” as=”foo”>
<f:cycle values=”{0: ‘odd’, 1: ‘even’}” as=”zebraClass”>
<li class=”{zebraClass}”>{foo}</li>

</f:cycle>

</f:for>

</ul> </code> <output> <ul>

<li class=”odd”>1</li> <li class=”even”>2</li> <li class=”odd”>3</li> <li class=”even”>4</li>

</ul> </output>

Note: The above examples could also be achieved using the “iteration” argument of the ForViewHelper
