Smarty comes with several custom plugin functions that you can use in the templates.
{counter} is used to print out a count.
{counter} will remember the
count on each iteration. You can adjust the number, the interval
and the direction of the count, as well as determine whether or not
to print the value. You can run multiple counters concurrently by
supplying a unique name for each one. If you do not supply a name,
the name “default” will be used.
If you supply the assign attribute, the output of the
{counter} function will be assigned to this template
variable instead of being output to the template.
| Attribute Name | Type | Required | Default | Description |
|---|---|---|---|---|
| name | string | No | default | The name of the counter |
| start | number | No | 1 | The initial number to start counting from |
| skip | number | No | 1 | The interval to count by |
| direction | string | No | up | The direction to count (up/down) |
| boolean | No | TRUE |
Whether or not to print the value | |
| assign | string | No | n/a | the template variable the output will be assigned to |
