Smarty modifiers can be applied to variables, custom functions or strings. You can use a modifier by adding a | (pipe) after the element you wish to modify and adding the modifier name. Modifiers can also accept parameters which are separated by a : (colon). These parameters must follow the order of their appearance in the signature.
Vanilla supports the built-in Smarty modifiers as documented on the Smarty site, and has created a few more for you to use in your templates. Learn more about Smarty modifiers from the Smarty site..
Modifier: asset_url
Converts a string to an asset url. Solves the problem of trying to using a relative path when Vanilla exists in a subfolder.
Example
In the following example, if the asset_url modifier was not specified, the image would not work if Vanilla existed in a subfolder. It also adds the domain name to the url and appends the theme version number.
<img
alt="My logo"
src="{"/themes/MyTheme/design/images/my-logo.png"|asset_url:true:true}"
>
Modifier: translate
Translates a string into the selected locale’s definition.
Example
This example outputs the breadcrumbs, where the home link text is the translated ‘Forum’ definition. Learn more about the breadcrumbs tag.
{breadcrumbs homelink="Forum"|translate}
