uploading!

anjuraju

Hi all!
I have a script that uploads a file.every time a user gives his/her id,he/she can upload a file.next time,if two users upload 2 diff files but with same name,there are high possibilities of the former one getting overwritten by the latest user's file.So,I want to figure out some way to give the uploaded file some id say the same name as the person's id so that I can avoid two problems:
1.The file being overwritten.
2.At the same time,if the same user wants to update the file,how can I do that?

Can anyone help me out with this?

Append the file name with "$id".

Updating the file...in what way? Do you mean the actual file or deleting and then replacing the file with a new one.

All in all, you can search this forum as it's been discussed many times before here.

phphp

u can use IP+time()+session_id() generate a unique file name

I want to rename the file after it has been uploaded with the ref id I have given for that particular user.Can you tell me how to do that?In a nutshell,I have to do the following:
1.Rename the uploaded file with the ref no
2.If the user uploads a second file,I have to locate his/her file and replace that file by the latest file that he/she is uploading
The code is as:
$target_path="/var/www/html/uploads/";
if(move_uploaded_file($FILES['uploadedfile']['tmp_name'],$target_path.$FILES['uploadedfile']['name'])){
print "successful uploading";
}
else{
print "possible file uploading attack";
}

Hello!Anybody there to help me?

You mean.. In one week time you have not found a solution to this? Have you even TRIED?

Anyway..

Use the new filename:

$newname = $userid.$target_path.$_FILES['uploadedfile']['name']

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'],$newname )){

With if(is_file($newname))

you can test beforehand whether a file with that name exists.

After testing with the appending code only,I have sent you hte message.Without trying,I would not send any message.
