Upload Help

[snike]

OK I have this:

//MOVE BUTTON TO FOLDER
if(move_uploaded_file ($_FILES['upload']['tmp_name'],"buttons/{$_FILES['upload']['name']}")) {
print "";
} else {
print "There was a problem uploading your file.";
exit;
}

I want it so that the file they are uploading already exists it changes to another name.

For example. A person uploads the file button.jpg. that file is uploaded. Now antoher person also uploads button.jpg but the name is changed to button4824,jpg or something like that.

also how can i make it so that they can only upload .jpg .gif and .png?

Is this an image host?

Instead of allowing an original name, the best way to avoid this is to save each image with a new name, usually a random name.
So say someone uploaded button.jpg, you could make it sdfg23sfd234gsdgdg_button.jpg
If another peson uploaded something called button.jpg, the random jibberish at the end would be different, thus avoiding overwriting files.

//Create unique jibberish
$unique = substr(md5(uniqid(rand())),0,10);
//MOVE BUTTON TO FOLDER
if(move_uploaded_file ($_FILES['upload']['tmp_name'],"buttons/".$unique."_".$_FILES['upload']['name'])) {
print "";
} else {
print "There was a problem uploading your file.";
exit;
}

That oughta do it for you if you'd like that kind of system.

Hope it helps,

if (isset($_FILES["upload"]["name"]));
{
if (($_FILES["upload"]["type"] == "image/png")
{
$unique = substr(md5(uniqid(rand())),0,10);
//MOVE BUTTON TO FOLDER
if(move_uploaded_file ($_FILES['upload']['tmp_name'],"buttons/".$unique."_".$_FILES['upload']['name'])) 
{
print "";
}
else
{
echo "There was a problem uploading your file.";
exit;
}  
}


if (($_FILES["upload"]["type"] == "image/gif")
{
$unique = substr(md5(uniqid(rand())),0,10);
//MOVE BUTTON TO FOLDER
if(move_uploaded_file ($_FILES['upload']['tmp_name'],"buttons/".$unique."_".$_FILES['upload']['name']))
{
print "";
}
else
{
echo "There was a problem uploading your file.";
exit;
}  
}


if (($_FILES["upload"]["type"] == "image/jpg")
{
$unique = substr(md5(uniqid(rand())),0,10);
//MOVE BUTTON TO FOLDER
if(move_uploaded_file ($_FILES['upload']['tmp_name'],"buttons/".$unique."_".$_FILES['upload']['name'])) 
{
print "";
}
else

exit;

}
}
else
{
echo "There was a problem uploading your file."

Maybe, the code is very scrappy cuz im tired, if it doesnt work, PM or wait till someone else posts

Also i included billy connites code for the random string, so yeah, give him credit.
