I have a form and processing script to upload a pdf and store it in a database with a a table called "pdf".  The uploading and retrieval works perfectly.  However, every time I upload a file, it is always the same one, even when I browse and choose  totally different file!

Here's the form processor.  If you want to see the actual form let me know:

$description = mysql_real_escape_string($_POST['description']);
$category = mysql_real_escape_string($_POST['category']);
$title = mysql_real_escape_string($_POST['whatsit']);
$ref = mysql_real_escape_string($_POST['ref']);

if ($errmsg == "") {
if ($_REQUEST[completed] == 1) {
        move_uploaded_file($_FILES['imagefile']['tmp_name'],"latest.img");
        $instr = fopen("latest.img","rb");
        $image = mysql_real_escape_string(fread($instr,filesize("latest.img")));
        if (strlen($instr) < 1000000) {
                mysql_query ("insert into pdf (title, imgdata, category, description, ref) values ('$title','$image', '$category', '$description', '$ref')");

                $errmsg = "Done";
        } else {
                $errmsg = "Too large!";
        }
} else {
        $errmsg = "Form not completed";
}}
?>

 

Here's how I retrieve it:

$pid=$_GET['id'];
$gotten = @mysql_query("select * from pdf WHERE pid ='$pid' ");
$row = @mysql_fetch_assoc($gotten);
$bytes = $row[imgdata];
header("Content-type: application/pdf");
header('Content-disposition: attachment; filename="thing.pdf"');
print $bytes;

 

(I get there with 

<a href="pdfget.php?id=<?php echo $row['pid'];?>"><?php echo $row['title'];?></a>

Sure:

<?php
session_start();
if(isset($_POST['category'])) {
$_SESSION['category'] = $_POST['category'];
$category = $_POST['category'];
} elseif (isset($_SESSION['category'])) {
$category = $_SESSION['category'];
} else {
$category = 'sepsis';
}
?>

hmm interesting. Does your database have the values you expect it to have? try echoing $pid and see what it has in it. Also, if pid is an int column, you can remove the single quotes around $pid in the query. single quotes denote strings
