ViewHelper，用于来自链接向导的链接

Question

I search a ViewHelper which helps to recognize, wether a link from the link wizard is a page link, a file link or an external link.

The reason for this is: i must include different icons depending from the link type, eG

header_link => '33'
header_link => 't3://file?uid=44'
header_link => 'spiegel.de' 

Answer 1

There is no viewhelper for this out of the box. You could write your own viewhelper which uses \\TYPO3\\CMS\\Core\\LinkHandling\\LinkService::resolve() to determine the type.

However I'd suggest to do this via CSS instead:

a[href^='http'] { /* external */ }
a[href^='/'] { /* internal */ }
a[href$='.pdf'] { /* pdf */ }
/* etc. */
