File Upload script - Need help.

Ericsson · Aug 13, 2005

Ive got a file upload script, how can I make it so it gives a random name or ads a few digits on the end instead of saying "change the filename" all the time.

Code:

<?
//set these variables-----------------------------------------------------------------
$path = "upload/";   //path to your targetfolder after your domain
$max_size = 500000;          //maximum filesize

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

//------------------------------------------------------------------------------------
?>

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

        <INPUT TYPE="file" NAME="userfile">

<br>
<?

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")) {

        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 {
        ?>
<br>

  </a></font></strong><br>
<?
 }
echo "<font color=\"#333333\" face=\"Geneva, Arial, Helvetica, sans-serif\"><hr>";
echo "Name: ".$HTTP_POST_FILES['userfile']['name']."<br>\n";

heres my script:

PHP:

Rand(1,9999999999)

it generates a random number between 1 and 9999999999 so you can have a lot of files hosted.

Were would I add that?
Thanks.

heres a script that I threw together:

The form on the page before:

Code:

<form action="upload.php" method="post" enctype="multipart/form-data" name="form1">
    <table width="414" border="0">
      <tr>
        <td width="158"><span class="style3">File Location: </span></td>
        <td width="246"><input name="uploadedfile" type="file" id="uploadedfile"></td>
      </tr>
    </table>
    <p>
      <input type="submit" name="Submit" value="Upload File">
</p>
  </form>

The php file (upload.php):

PHP:

<?php
 // Where the file is going to be placed temporarly
$target_path = "/";

$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);

$_FILES['uploadedfile']['tmp_name']; // temp file

$target_path = "./uploads/";
$oldfile =  basename($_FILES['uploadedfile']['name']);


//Check the size
if($_FILES['uploadedfile']['size'] > 500000{
    die( "File too large!");
}

//new file name 

$newfile = Rand(1,9999999999) . $_FILES['uploadedfile']['name'];

// move the file to the final destination
$target_path = $target_path . basename($newfile);

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
	 die( "File Uploaded");
} else{
     die("Upload Error");
}
?>

That should work

Another way to do this is.

PHP:

$uniq = substr( md5(uniqid (rand())), 0, 10 );
$ext = strtolower( substr($_FILES['uploadedfile']['name'], -3));
move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $att_path."/".$uniq.".".$ext );

Edited your code:

PHP:

<?php
// Where the file is going to be placed temporarly
$_FILES['uploadedfile']['tmp_name']; // temp file

$target_path = "./uploads/";//Make sure chmodded to 777
$oldfile =  basename($_FILES['uploadedfile']['name']);
$allowed_types = array("gif","jpg","png","jpeg","pdf","bmp");

//Check the size
if($_FILES['uploadedfile']['size'] > 500000{
    die( "File too large!");
}

//Check file type
if(!in_array(stristr($_FILES['uploadedfile']['name'], "."), "$allowed_types")) {
    die( "File type not allowed!");
}

//new file name
$uniq = substr( md5(uniqid (rand())), 0, 10 );
$ext = strtolower( substr($_FILES['uploadedfile']['name'], -3));
move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $path."/".$uniq.".".$ext );
?>

I add file type check code as well

Good Luck!
