{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.

The above template would output:
|

|
|
|
||
|
|
|
||
|
|
<tr class="odd">
|
||
|
|
<td>1</td>
|

|
|

|
||
|
|
<tr class="even">
|
||
|
|
<td>2</td>
|
||
|
|
</tr>
|
||
|
|
<tr class="odd">
|
||
|
|
<td>3</td>
|
||
|
|
</tr>
