Language switcher in my header?
Eviltomh89 - May 6, 2009 - 11:24
HI all,
I was wondering whether it is possible to place a language switcher in the header of my website.
Already i have found the page.tpl.php file and tried to change it, but simply putting the code of the language module i have installed in the page.tpl.php isn't working
here is the code i made up

Help is much appreciated!!
Thnx in advance
Tom
create a region in header and
create a region in header and place that languages block in that region
add a region in your theme .info file
add css in your theme css file
and print that region in page.tpl.php
thats it

Hi manasapenchala, thanks for
Hi manasapenchala,
thanks for your explanation,
But the first thing you said, doesn't make any sense to me :(
How do i place the language block in the header region?
And how do i add the header as a block, so that i can place also other stuff in the header.
Regards,
Tom
