PHP - Need Help Wile Uploading A File (unique Name Required)

Hi guys,

So here is the deal.

We have a list of brands that excists in a database. There are also images associated with the names. But not all the brands have images. So in the script i read if the file excists.

Well this all works fine but it looks horrible. So i want to break the list in half (or limit it to 24). But i cant limit the sql query.

Is there a way to "limit" a while loop and let it resume on the same page, just to change the layout (multiple collumns)? (I hope i am clear on this... i confuse even myself)



$host = 'localhost';
$user = 'qwerty';
$pass = 'qwerty';
$db = 'qwerty';

$query = "SELECT * FROM ros_brands";

$result = mysql_query($query) or die(mysql_error());

$filename = "/resources/images/mm_files/" . $row['image_file_id'] . ".gif";

while($row = mysql_fetch_array($result)){

$filename = "/var/www/vhosts/test.nl/httpdocs/resources/images/mm_files/" . $row['image_file_id'] . ".gif";

if (file_exists($filename)) {
        echo    "<a href='#'><img src='/resources/images/mm_files/" . $row['image_file_id'] . ".gif' /><span>". $row['name'] ."</span></a>";

} else {
//    echo "The file $filename does not exist";
}

}

Hey all

So have been working on a file upload script, it was uploading the file but also adding the path name instead of NULL to mysql when no image was to upload, that is now fixed however now it won't upload the actual image to the directory.  I tried undoing the mysql changes but it still won't upload the image to the directory.  Am testing on my own computer using xampp so no file permission issues, plus it was working before.  Any help much appreciated.

Thanks

Whats the easiest way to rename uploaded files to a unique name that would never be duplicated?

I append a string to a file by fwrite as

Code: [Select]
$str= 'dynamic text from each run';
$myFile = "testFile.txt";
$fh = fopen($myFile, 'a') or die("can't open file");
$stringData = "$str\n";
fwrite($fh, $stringData);
fclose($fh);
but I want to avoid duplicate to keep the file small. I want to avoid writing if the term is already saved in the file. I want to have a file containing unique lines.

I'm having a problem with getting the timestamp to attach to the filename.  Currently when it's uploaded in the database it says $timestamp in front of the filename instead of the time.

Scroll down towards the bottom of the code to see it.  Thanks for your help!
