Rename uploaded images from a form

ElRollo24

Ok, here's the situation. I'm working on a little upload script and so far I have it working. It checks the file type and uploads to the correct directory and I have it add a row to the database which stores their username, which is what they're logged in as, the date they submitted the file and a unique ID, which is just mysql_insert_id(). The directory that everyone is uploading to is going to be the same, so I wanted to rename the file that they're uploading to something else, like their username, then after that the unique ID given to that file.

if(isset( $upload ))
{
if ($FILES['imagefile']['type'] == "image/x-png"){
copy ($FILES['imagefile']['tmp_name'], "images/screenshots/".$_FILES['imagefile']['name'])
or die ("Could not copy");
}
else{
blah blah not important
}
}
else{
blah blah blah not important
}

That's the main jist of the copying part. It gets the filename and file type from the form that the user submits, and it just copies it from that. What I want to do is just change the filename (imagefile) from what they submit to something unique so they don't overwrite any other files and it's in a somewhat organized fashion in the directory.

I appreciate the help :o

i'm a terrible coder, but here is my very simplistic solution...

have the query take the name of the file, query the database for anything with the exact same name...if it's exists just append the file with something...if not, it's good...

in the past, i've used this great script...but i can't remember where i got it..."fileupload-class.php"...it has everything, and even i was able to modify the heck out of it for some things...

good luck...vaska

You could use tmp_name rather than name, it'll give you a more jumbled up name, but also a .tmp extension. If you wanted to save as a PNG, you could just write over the last three letters of it.

If you want to use the ID and the username, you'll first need to find out the id, which might require another mysql_query(). From there, just concatenate the name and the id, along with the extension:
$name.$id.".png"

Here's an idea for you: why not save the image in a database; that way you can refer to it using the primary index, and you can save comments or whatever you need along with the image... Even have it delete itself after a certain amount of time.

See this phpbuilder article for details

Thanks for the advice. I ended up doing what Mordecai suggested. Just made $_FILES['imagefile']['name'] = "$author$picid.png";

Just got finished testing it and it works great. Thanks again for all the suggestions.
