Undefined variable problem - hi, its been awhile...

Kinsbane

okay workin on an upload script - its one ive had for awhile, and its worked before - well I'm bringing it back for a board I visit but I'm having a problem.

I have this section of code:

$dbh=mysql_connect ('localhost', 'e_novative', 'e_novative') or die ('I cannot connect to the database because: ' . mysql_error());
mysql_select_db ('uploads'); 

$dir = "dir";
if ($file != "") {

if (file_exists("$absolute_path/$file_name")) {
die("File already exists");
}

The line that says if ($file != "") { throws me an error. This is in the section of code for it to upload the file then post the path and the filename along with an ID number to a mysql database. After I try to upload the file, it gives me this error:

Notice: Undefined variable: file in \files\upload.php on line 256

Line 256 is the one where it checks to see if variable $file is not empty. I dont know how to fix this. 🙁

First, do you have register globals to on or off?

if off, you could get away with seeing if it is set, then if it is nothing(which probly won't happen if it's not set)

<?php
if (isset($file) && $file != '')
?>

Welp, that solved the error alright.

However, when I get to the page that's supposed to show the uploaded file, all it says is "Must select file to upload" - some error handling I put in there. 😕

If off, you'll have to go through the GLOBAL variable $_FILES...look here
