rename() problem ???

[archive]

hello guys

I'm trying to move some pics from a folder called /tmp to a folder called /photos.

I've stored the image filename in:
$_SESSION['pic1']

The code i'm using is the following:
rename("tmp/".$_SESSION['pic1']."", "photos/".$_SESSION['pic1']."");

but i get the following error:
Warning: rename(tmp/,photos/) [function.rename]: File exists in C:\wamp\www\site.com\v3\control.php on line 69

When i alter my code and instead of the SESSION variable i use the actual filename.jpg, everything works smoothly!

Any clue???

notice that the warning does not include your filename? i think your session variable isn't set. have you tried echo'ing $_SESSION['pic1'] to see if it's set?

also, why do you have the ."" after the session variable?

The problem is obviously that the session variable isn't being set. Are you sure you're setting the session variable correctly? Perhaps you've forgotten to do session_start() at the top of the page?

Also, why are you concatenating an empty string after the session variable? There is no point.

 rename("tmp/".$_SESSION['pic1']."", "photos/".$_SESSION['pic1'].""); 

is identical to

 rename("tmp/".$_SESSION['pic1'], "photos/".$_SESSION['pic1']);

absolutely correct my friends!

though i had set session_start(), i hadn't refreshed my page so as for the session to start correctly....

once again thank you!
