4 | * Outputs a html <a> tag |
---|
5 | * <pre> |
---|
6 | * * href : the target URI where the link must point |
---|
7 | * * rest : any other attributes you want to add to the tag can be added as named parameters |

8 | * </pre> |

---|
10 | * Example : |
---|
11 | * |
---|
12 | * <code> |
---|
13 | * {* Create a simple link out of an url variable and add a special class attribute: *} |
---|
14 | * |
---|
15 | * {a $url class="external" /} |
---|
16 | * |
---|
17 | * {* Mark a link as active depending on some other variable : *} |
---|
18 | * |
---|
19 | * {a $link.url class=tif($link.active "active"); $link.title /} |
---|
20 | * |
---|
21 | * {* This is similar to: <a href="{$link.url}" class="{if $link.active}active{/if}">{$link.title}</a> *} |
