checking a variable being passed

Postby mpgalvin » Wed Sep 24, 2003 2:57 pm

I use forms to post values to a page, but I quite often use links for the same purpose (for example, paging a db). This means that for every

Code: Select all

if (isset($HTTP_POST_VARS['value']))

I have to have a

Code: Select all

if (isset($HTTP_GET_VARS['value']))

Is there a better way of doing this (without making the assumption that $value will always exist regardless of whether it's posted or sent in a link?
