Surely $_POST is a superglobal and will thus be available within the
function scope just as it would be within the macro "scope".
Couldn't you do something like this (untested code, function name is
deliberately bad)?
function get_post_var_with_default($name, $default = 'default value')
{
if (isset($_POST[$name]))
{
return $_POST[$name];
}
else
{
return $default;
}
}
then later
$var = get_post_var_with_default('postvar');
Am I missing something here?
