Comparing changes: https://github.com/smarty-php/smarty/compare/v4.3.1...v4.4.1 It is noticeable that Smarty 4.3.1 does not officially support PHP 8.3. Is only supported with 4.4.0. Remark: During tests with Smarty 4.5.1, it was noticed that the following warning occurs: Deprecated: Using the unregistered function "function_exists" in a template is deprecated and will be removed in a future version. Use Smarty::registerPlugin to explicitly register a custom modifier. As of Smarty 5.X.X, templates must be revised again. The Smarty release 5.0.2 is already officially available. However, integration into FlatPress is not entirely trivial.

# {for}
|
|
|
|
The `{for}{forelse}` tag is used to create simple loops. The following different formats are supported:
|
|
|
|
- `{for $var=$start to $end}` simple loop with step size of 1.
|
|
|
|
- `{for $var=$start to $end step $step}` loop with individual step
|
|
size.
|
|
|
|
`{forelse}` is executed when the loop is not iterated.
