Certain text causes $_POST to disappear

[sccr410]

I use the same code that I have used on every single site I've developed. However, for this one site (music reviews), anytime they include the text "CD sometext", it causes the POST variable to act as if it didn't exist. If they use "CD/DVD", it's fine. "CD." (at the end of a sentence) then it's fine. Its just any time they input " CD " with spaces around it.

I've tested this by doing this in the code:

print_r($_POST);

Anytime "CD sometext" is in one of the POST variables, nothing gets displayed. Simply take out the "CD" and it works with no problems.

PHP 4.3.10

This is either a wind-up or there is another force in play.

I turned debugging as high as possible - it didn't cause any PHP errors. I imagine this has something to do with the CMS I created.

Change this print_r($_POST); to var_dump($_POST);

After a little more testing, it looks like it is causing a 404 error. It could possibly be the host doing some kind of filtering on POST variables to prevent attacks maybe?

OK, that's what it is - a horrible hosting setup. Any time a POST var has a unix command in it, "rm", "cd", "ls", etc it poops out.
