renaming uploaded picture

sniped22 · February 28, 2007

On one page, an upload box. This page uploads the image and generates info on profile.php.

<?php


function createRandomUrl() {

    $chars = "abcdefghijkmnopqrstuvwxyz023456789";
    srand((double)microtime()*1000000);
    $i = 0;
    $pass = '' ;

    while ($i <= 15) {
        $num = rand() % 33;
        $tmp = substr($chars, $num, 1);
        $pass = $pass . $tmp;
        $i++;
    }

    return $pass;

}


function createRandomPic() {

    $chard = "abcdefghijkmnopqrstuvwxyz023456789";
    srand((double)microtime()*1000000);
    $i = 0;
    $pass = '' ;

    while ($i <= 5) {
        $num = rand() % 33;
        $tmp = substr($chard, $num, 1);
        $pic = $pic . $tmp;
        $i++;
    }

    return $pic;

}

$file = $_FILES["file"]["name"];

$password = createRandomUrl();
echo "Your link is: http://localhost/nextsite/upload/".$password.".html";

echo '<br>';

$new_page = "upload/".$password.".html";

$somecontent = '<html>
<body>
<img src="../upload/'.$file.'"> 
</body>
</html>';

$handle = fopen($new_page, 'w');


fwrite($handle, $somecontent);
     
    fclose($handle);


   echo "Upload: " . $_FILES["file"]["name"] . "<br />";
    echo "Type: " . $_FILES["file"]["type"] . "<br />";
    echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";


echo "Your hotlink for forums is: [url]http://localhost/nextsite/upload/".$password.".html[/url]";

      move_uploaded_file($_FILES["file"]["tmp_name"],
      "upload/" . $_FILES["file"]["name"]);












?>

how can I rename the uploaded image to its current file name along with another random string at the end. For example, i upload a.bmp, I want the file to be renamed to a1b5.bmp

Any help?

Thanks

$arrName = explode(".", $_FILES["fie1"]["name"]);

$name = $arrName[0].rand(1,9);

$ext = $arrName[1];

$newName = $name.".".$ext;

$destination = $newName;

then use

move_uploaded_file ( $_FILES["fie1"]["tmp_name"], $destnation)
