Random file name
-
Here is the code to generate a random file name on each upload, to avoid overwriting previous files. ->
File: upload_name.php
[code=php]
<?php<br />
if (!empty($_FILES)) {
$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $_SERVER['DOCUMENT_ROOT'] . $_GET['folder'] . '/';
$ext = pathinfo($_FILES['Filedata']['name'], PATHINFO_EXTENSION); //figures out the extension
$newFileName = md5($tempFile).'.'.$ext; //generates random filename, then adds the file extension
$targetFile = str_replace('//','/',$targetPath) . $newFileName;
move_uploaded_file($tempFile,$targetFile);
}
if ($newFileName)
echo $newFileName;
else // Required to trigger onComplete function on Mac OSX
echo '1';
?>
[/code] -
I figured out that you can set php highliting for the code block like so:
[code=php]<?</span>php
if (!empty($_FILES)) {
$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $_SERVER['DOCUMENT_ROOT'] . $_GET['folder'] . '/';
$ext = pathinfo($_FILES['Filedata']['name'], PATHINFO_EXTENSION); //figures out the extension
$newFileName = md5($tempFile).'.'.$ext; //generates random filename, then adds the file extension
$targetFile = str_replace('//','/',$targetPath) . $newFileName;
move_uploaded_file($tempFile,$targetFile);
} [/code]
instead of [code] you put [code=php]...for future reference... -
hi
i'd like to share my way in generating names
[code=php]$newFileName = md5(uniqid(rand().time(), true)) . substr($_FILES['Filedata']['name'], strrpos($_FILES['Filedata']['name'], ".")); [/code]
good luck
-
if (!empty($_FILES)) {
$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $_SERVER['DOCUMENT_ROOT'] . $_GET['folder'] . '/';
$ext = pathinfo($_FILES['Filedata']['name'], PATHINFO_EXTENSION); //figures out the extension
$newFileName = md5($tempFile).'.'.$ext; //generates random filename, then adds the file extension
$targetFile = str_replace('//','/',$targetPath) . $newFileName;
// Uncomment the following line if you want to make the directory if it doesn't exist
// mkdir(str_replace('//','/',$targetPath), 0755, true);
//echo "$tempFile => $targetFile";
move_uploaded_file($tempFile,$targetFile);
hey it did not work for me until i took out the } at the end
Just a little tip for people who may have used it and it has not worked. -
Sir, I'd like to read more of your articles.
