This little trick can be useful for calling custom functions and printing the title with out spaces for W3C compatibility. I used this trick in a new theme called Galleria, which will be out for public download in the coming days.
Using this comes in handy for a delicious text link:
<?php $title = get_the_title(); ?> <a href="http://del.icio.us/post?url=<?php echo $title; ?>&<?php echo str_replace(" ", "%20", $title); ?>"> Bookmark This (<?php echo $title; ?>)</a>
What I am doing is calling
$title = get_the_title(); and using
str_replace(" ", "%20", $title); to replace empty spaces with a
%20, which is used in URL encoding empty spaces.
Alternatively you can use a dash or underscore.
Thanks to Jason Boyle for his adaption.
