  Old  image uploading, need help

Hey guys,

I wrote this pretty quickly; http://screensnapr.com/v/Q2SqQJ.png

If the file doesnt exist, then it uploads and saves the image fine. But, if the file does already exist, then i add an 8 digit number to the beginning of the file. It gives the url fine, but the problem is, it doesnt save the image.

Any ideas guys?

Firstly, I'd create random generated names for the images so you don't need to do a check if it exists, work on it time so the number can only go forward, saves the if/else malarky.

Post removed, updating code. Brb.

I come up with a solution, just dont even check if it exists...

PHP Code:
$random_digit=rand(00000000,99999999);

move_uploaded_file($_FILES["file"]["tmp_name"],
"images/" $random_digit $_FILES["file"]["name"]);
$newthumb "images/" $random_digit $_FILES["file"]["name"];

While the chances of a duplicate are slim the only completely sure way to do it is to use a do...while loop and rename it every time an existing one is made, to give a quickly typed pseudocode example

PHP Code:
$uploaded=false;
do{
$randNum=rand(0,99999);
if 
file+$randnum does not exist
upload file
$uploaded
=true;
end if
} while(
$uploaded==false);

That random digit think should do the work, but as they said, I'd try to slim down the chances by adding at least one or two characters at the end or beggining of the name, it's better to avoid than to regret.

Cheers!
