Need PHP Help.

hexthem4n · 07-04-2006, 10:49 PM

I need the following code to put a random number onto the file name. Like say you upload image.jpg, I want it to be like 213image.jpg after its uploaded. So that I dont have to worry about people getting the re-name your image error. Any help would be awsome! Here is the code.

PHP Code:

  <?

//set these variables-----------------------------------------------------------------

$path = "test/uploads/";   //path to your targetfolder after your domain

$max_size = 1000000;          //maximum filesize

 
//optionally

$domain = $_SERVER["HTTP_HOST"];      //your domainname - change if necessary like "www.wza.be"

????: NamePros.com http://www.namepros.com/programming/213593-need-php-help.html
 
//------------------------------------------------------------------------------------

?>

 
<?

 
if (!isset($HTTP_POST_FILES['userfile'])) exit;

 
if (is_uploaded_file($HTTP_POST_FILES['userfile']['tmp_name'])) {

 
if ($HTTP_POST_FILES['userfile']['size']>$max_size) {

        echo "<font color=\"#333333\" face=\"Geneva, Arial, Helvetica, sans-serif\">File is too big !</font><br>\n"; exit; }

if (($HTTP_POST_FILES['userfile']['type']=="image/gif") || ($HTTP_POST_FILES['userfile']['type']=="image/pjpeg") || ($HTTP_POST_FILES['userfile']['type']=="image/jpeg") || ($HTTP_POST_FILES['userfile']['type']=="image/png")) {

????: NamePros.com http://www.namepros.com/showthread.php?t=213593
 
        if (file_exists("../".$path . $HTTP_POST_FILES['userfile']['name'])) {

                echo "<font color=\"#333333\" face=\"Geneva, Arial, Helvetica, sans-serif\">There already exists a file with this name, please rename your file and try again</font><br>\n"; exit; }

 
        $res = copy($HTTP_POST_FILES['userfile']['tmp_name'], "../".$path .$HTTP_POST_FILES['userfile']['name']);

 
        if (!$res) { echo "<font color=\"#333333\" face=\"Geneva, Arial, Helvetica, sans-serif\">Didn't work, please try again</font><br>\n"; exit; } else {

you can use uniqid()

bttfpromo · 07-05-2006, 08:45 PM

Ahahaha....I have this done on my own website... You'll need to change variables and what's highlighted.

PHP Code:

          $micro=substr (md5 (microtime ()), 1, 3);

????: NamePros.com http://www.namepros.com/showthread.php?t=213593
    rename('[b]files/[/b]'.$uploaded_file_name, '[b]files/[/b]'.$micro. $uploaded_file_name);

    $uploaded_file_name=$micro.$uploaded_file_name;

i would recomend changing $micro=substr(...) to something like $micro=rand(1,999) if you wish to keep the orginal file name in the "name". md5 makes hex numbers, meaning you can get the letters a-f in there as well FYI.
