Template Tag Cycle

Template tag cycle.

Cycle among the given strings or variables each time this tag is encountered.

Within a loop, cycles among the given strings each time through the loop:

{foreach $some_list as $obj}
    <tr class="{cycle 'row1', 'row2'}">
        ...
    </tr>
{/foreach}

You can use variables, too. For example, if you have two template variables, $rowvalue1 and $rowvalue2, you can cycle between their values like this:

{foreach $some_list as $obj}
    <tr class="{cycle $rowvalue1, $rowvalue2}">
        ...
    </tr>
{/foreach}

You can mix variables and strings:

{foreach $some_list as $obj}
    <tr class="{cycle 'row1', rowvalue2, 'row3'}">
        ...
    </tr>
{/foreach}

In some cases you might want to refer to the next value of a cycle from outside of a loop. To do this, just group the arguments into an array and give the {cycle} tag name last, like this:

{cycle array('row1', 'row2'), 'rowcolors'}

From then on, you can insert the current value of the cycle wherever you'd like in your template:

<tr class="{cycle $rowcolors}">...</tr>
<tr class="{cycle $rowcolors}">...</tr>

Based on concepts from the Django cycle template tag.
