Module development and code questions

I'm trying to create a new content type using the flexinode module for events for the event module. The biggest problem I'm having is that the "Start" and "End" fields always show up at the bottom, below my description field. I tried setting the description field weight to 10 and that didn't help at all. I'm letting the event module inject the two fields into the creation form. I tried adding them to the node content type manually, hoping if I had a "Start" and "End" field in there then the event module would use those instead of injecting it's own, but that didn't work.

Okay feeling pretty stupid so I've got to ask for help...

Hi,

Iam up to creating my secondary menu. It should have different sections like:

E.g.

http://www.domain.com/tea
http://www.domain.com/tea/lemon
http://www.domain.com/tea/wildberry/1202 (where the number is the article number)

Hello all,

Scratching my head over this... How comes this works:

$string = "hello world";
print check_plain($string);
if (check_plain($string) === $string) {
print "<p>match";
}
else {
print $string;
}

But this doesn't?

We want to convert urls in content and menus to relative urls if they are local. ie.
from: http://my.example.com/~dev/?q=/node/30
to: l(/node/30) or ?q=/node/30

The motivation for this is so that links do not break when we move a site from dev to live. The url conversion must happen upon submission. Could someone suggest a way to do this. Something in wiki.module could be used for general content, but what about menus?
