Change file name of uploaded image?

[lisa99]

Hi.

Can someone help me change the name of an uploaded image?

I've tried almost everything. I know I'm new to this, but I'm awful frustrated. I have the login/logout functions working, mysql inserts, and other things working, but I've been working on this all day (and yes, I even read the manual followed by hours of googling) but I just don't get it.

Here's the code:

//upload image
$target = "estickerimages/";
$ok=1;

//check size
if ($uploaded_size > 350000)
{
echo "Your file is too large.<br>";
$ok=0;
}

//create file extension in variable $imagetype
if ($uploaded_type =="image/jpg")
{
$imagetype=".jpg";
}
if ($uploaded_type =="image/jpeg")
{
$imagetype=".jpeg";
}
if ($uploaded_type =="image/bmp")
{
$imagetype=".bmp";
}
if ($uploaded_type =="image/gif")
{
$imagetype=".gif";
}
if ($uploaded_type =="image/png")
{
$imagetype=".png";
}
if (empty($imagetype))
echo "That file type is not allowed.<br>";

//check that $ok was not set to 0 
if ($ok==0)
{
echo "Sorry.  Your file was not uploaded.";
}
//If everything is ok try to upload it
else
{
$target = $target . basename( $_FILES['uploaded']['name']) ;

if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target))
{
echo "Your image was uploaded.";
}
else
{
echo "Sorry, there was a problem uploading your file.";
}
}

//end upload image

I have tried using the pathinfo function, echoing variables, etc, but I can't seem to change the name and have it save properly. Where is the saving of the file done? In "move_uploaded_file"?

Do you have permissions to write files to "estickerimages" directory? In a pinch you can chmod 777 that directory, which I don't like but sometimes its your only choice.

Also appears if $imagetype is not set that $ok could still be value of 1.

Sorry. I wasn't very clear.

The code works. It uploads the image and saves properly.

What I'm trying to do is to remove the original file name completely (to avoid duplicate names and spaces/slashes causing problems) and replace it with essentially a unique userid (in my case $stickernumber).

This is my temporary fix...

//upload image
$target = "estickerimages/$stickernumber"; //$stickernumber works here.
//I get a unique name, but with the original filename attached on the back.  

$ok=1;

//check size
if ($uploaded_size > 350000)
{
echo "Your file is too large.<br>";
$ok=0;
}

//create file extension in variable $imagetype
if ($uploaded_type =="image/jpg")
{
$imagetype=".jpg";
}
if ($uploaded_type =="image/jpeg")
{
$imagetype=".jpeg";
}
if ($uploaded_type =="image/bmp")
{
$imagetype=".bmp";
}
if ($uploaded_type =="image/gif")
{
$imagetype=".gif";
}
if ($uploaded_type =="image/png")
{
$imagetype=".png";
}
if (empty($imagetype))
echo "That file type is not allowed.<br>";

//check that $ok was not set to 0
if ($ok==0)
{
echo "Sorry.  Your file was not uploaded.";
}
//If everything is ok try to upload it
else
{
$target = $target . basename( $_FILES['uploaded']['name']) ;
//here is where it is attaching the original filename on the back, I think.
//is there a way to change the ['name'] and set it to $stickernumber?
//I have tried several different ways, but nothing has worked.  

if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target))
{
echo "Your image was uploaded.";
}
else
{
echo "Sorry, there was a problem uploading your file.";
}
}

//end upload image
