{cycle} {#language.function.cycle}
=======
`{cycle}` is used to alternate a set of values. This makes it easy to
for example, alternate between two or more colors in a table, or cycle
through an array of values.
Attribute Name Type Required Default Description
---------------- --------- ---------- ----------- -------------------------------------------------------------------------------------------------------------
name string No *default* The name of the cycle
values mixed Yes *N/A* The values to cycle through, either a comma delimited list (see delimiter attribute), or an array of values
print boolean No *TRUE* Whether to print the value or not
advance boolean No *TRUE* Whether or not to advance to the next value
delimiter string No *,* The delimiter to use in the values attribute
assign string No *n/a* The template variable the output will be assigned to
reset boolean No *FALSE* The cycle will be set to the first value and not advanced
- You can `{cycle}` through more than one set of values in a template
by supplying a `name` attribute. Give each `{cycle}` an unique
`name`.
- You can force the current value not to print with the `print`
attribute set to FALSE. This would be useful for silently skipping a
value.
- The `advance` attribute is used to repeat a value. When set to
FALSE, the next call to `{cycle}` will print the same value.
- If you supply the `assign` attribute, the output of the `{cycle}`
function will be assigned to a template variable instead of being
output to the template.
<!-- -->
{section name=rows loop=$data}
<tr class="{cycle values="odd,even"}">
<td>{$data[rows]}</td>
</tr>
{/section}
The above template would output:
<tr class="odd">
<td>1</td>
</tr>
<tr class="even">
<td>2</td>
</tr>
<tr class="odd">
<td>3</td>
</tr>
