/**
|
|
* Outputs a html <a> tag
|
|
* <pre>
|
|
* * href : the target URI where the link must point
|
|
* * rest : any other attributes you want to add to the tag can be added as named parameters
|
|
* </pre>
|
|
*
|
|
* Example :
|
|
*
|
|
* <code>
|
|
* {* Create a simple link out of an url variable and add a special class attribute: *}
|
|
*
|
|
* {a $url class="external" /}
|
|
*
|
|
* {* Mark a link as active depending on some other variable : *}
|
|
*
|
|
* {a $link.url class=tif($link.active "active"); $link.title /}
|
|
*
|
|
* {* This is similar to: <a href="{$link.url}" class="{if $link.active}active{/if}">{$link.title}</a> *}
|
