Hi,
I am using a script to allow users to upload their profiles and renaming them while keeping the extensions - docx, pdf, jpg, etc.
Each user has a unique user number. The renamed files would look like this: profile_usernum.extension, e.g profile_351.pdf
The user number is retrieved from a database. The script works, except that the user number (UserNum) is not carried after submitting the form. So, I end up with "profile_.pdf" instead of "profile_351.pdf".
Please note that session_start() is stated at the top of each script. The files are mentioned below. I've been trying to solve this for 4 days now with no avail.
Please help.
There are 3 files:
main.php
<?php
session_start();
// code to retrieve UserNum from database
$_SESSION ['UserNum'] = $UserNum;
$UserNum = $_SESSION ['UserNum'];
include "upload.php";
?>
upload.html
<!DOCTYPE html>
<html>
<body>
<form action="upload.php" method="post" enctype="multipart/form-data">
Select file to upload:
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload" name="submit">
</form>
</body>
</html>
upload.php
<?php
session_start();
$UserNum = $_SESSION ['UserNum'];
// to check that $UserNum is there:
echo $UserNum; // correctly displayed only before submitting the form
include "upload.html";
$submit=$_POST["submit"];
$target_dir = "profiles/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$extension = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
// changing the name of uploaded file
$myfile = $target_dir . "profile_" . $UserNum . "." . $extension;
if (isset($submit))
{
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $myfile)) {
echo "The file has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
}
?>
