I have a page that uploads images. My problem is some of the names aren't usable for linking or opening in browsers. Is there a way to make it numbers and characters only that way it can be used in the browser(since the script is to make pictures with encrypted names)

Does a 404 error happen if a script tries to include a file that doesn't exist. If it does how how do i find out about it. I keep getting 404 error reports(i set my 404 page to email me) and i haven't tried viewing any page that doesn't exist(and i know no one visits my site) And i don't know what page the 404 error is coming from, i've got the $_SERVER['HTTP_REFERER'] variable, but that doesn't seem to work.

I have another question. I have a form that will be for updating rows of the table, the stuff is going to go in a textarea and has html tags. Right now it just shows the last bit of it, but in the source it has all the other stuff. nevermind, i got it(i'm an idiot)

Is there a way with PHP to get the link that results in a 404, that way my custom 404 page can pass the info to me threw the mail function? And will, [code] function ($_POST[]); [/code] Do the same as [code] function ($_POST['a']); function ($_POST['b']); function ($_POST['c']): and so on... [/code]
