rename image -php upload

davieboy

im using

<?php

$uploaddir = '/home/username/public_html/img1/';
$uploadfile = $uploaddir . basename($_FILES['userfile']['name']);

echo '<pre>';
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
   $my_files = $_FILES['userfile']['name'];
   echo "<a href=\"http://domain.com/img1/$my_files\">Link</a><br>";
	echo "URL LINK: <b>http://domain.com/img1/$my_files</b><br><br>";
	echo "uploaded image:<br><img src=\"http://domains.com/img1/$my_files\" width=\"250\" height=\"200\">";

} else {
   echo "ERROR! PLEASE TRY AGAIN!\n";
}

print "</pre>";

?>

how do i create a random name based on the timestamp and stuff to rename the file to to prevent overwrites?

So take the extension off the uploaded filename and put it on the end of the new filename.

ok i have managed to get the file extention.

i cant get the code to re-write the name and save it under its new name

You could do the following:

$randFilename = uniqid("img_");
$newFilename = $randFilename.".".$oldFileExt;

if (move_uploaded_file($_FILES['userfile']['tmp_name'], $filePath.$newFilename))

Best,
