[wp-hackers] Cleaning up small validation errors in the admin interface

[Dion Hulse (dd32)]

I'd be looking in the direction of esc_url();

It should be used when the url is to be printed to screen.

for example:

echo '<A href="' . esc_url(get_some_link()) . '>';

It'll produce a link such as:
http://test.com/?a=b&#038;test=test3

(&#038; being the numeric representation of &amp;)
