hi frds...

  i got below upload coding from one website.i implented my website too..

 

// make a note of the current working directory, relative to root.

$directory_self = str_replace(basename($_SERVER['PHP_SELF']), '', $_SERVER['PHP_SELF']);

 

// make a note of the directory that will recieve the uploaded files

$uploadsDirectory = $_SERVER['DOCUMENT_ROOT'] . $directory_self . 'up_files/';

 

// make a note of the location of the upload form in case we need it

$uploadForm = 'http://' . $_SERVER['HTTP_HOST'] . $directory_self . 'gfile.php';

 

// make a note of the location of the success page

$uploadSuccess = 'http://' . $_SERVER['HTTP_HOST'] . $directory_self . 'gfile.php';

 

// name of the fieldname used for the file in the HTML form

$fieldname = 'file';

  // $fieldname = 'file1';

 

//echo'<pre>';print_r($_FILES);exit;

 

// Now let's deal with the uploaded files

 

// possible PHP upload errors

$errors = array(1 => 'php.ini max file size exceeded',

2 => 'html form max file size exceeded',

3 => 'file upload was only partial',

4 => 'no file was attached');

 

// check the upload form was actually submitted else print form

if(isset($_POST['submit']))

{

// or error('the upload form is neaded', $uploadForm);

// check if any files were uploaded and if

// so store the active $_FILES array keys

$active_keys = array();

foreach($_FILES[$fieldname]['name'] as $key => $filename)

{

if(!empty($filename))

{

$active_keys[] = $key;

// echo $key;

}

}

// check at least one file was uploaded

count($active_keys)

or error('No files were uploaded', $uploadForm);

 

// check for standard uploading errors

foreach($active_keys as $key)

{

($_FILES[$fieldname]['error'][$key] == 0)

or error($_FILES[$fieldname]['tmp_name'][$key].': '.$errors[$_FILES[$fieldname]['error'][$key]], $uploadForm);

}

 

// check that the file we are working on really was an HTTP upload

foreach($active_keys as $key)

{

@is_uploaded_file($_FILES[$fieldname]['tmp_name'][$key])

or error($_FILES[$fieldname]['tmp_name'][$key].' not an HTTP upload', $uploadForm);

}

 

// validation... since this is an image upload script we

// should run a check to make sure the upload is an image

foreach($active_keys as $key)

{

@getimagesize($_FILES[$fieldname]['tmp_name'][$key])

or error($_FILES[$fieldname]['tmp_name'][$key].' not an image', $uploadForm);

}

 

// make a unique filename for the uploaded file and check it is

// not taken... if it is keep trying until we find a vacant one

foreach($active_keys as $key)

{

$now = time();

//while(file_exists($uploadFilename[$key] = $uploadsDirectory.$now.'-'.$_FILES[$fieldname]['name'][$key]))(it wil show serve time)     

while(file_exists($uploadFilename[$key] = $uploadsDirectory.$_FILES[$fieldname]['name'][$key]))

{

$now++;

}

}

 

// now let's move the file to its final and allocate it with the new filename

foreach($active_keys as $key)

{

@move_uploaded_file($_FILES[$fieldname]['tmp_name'][$key], $uploadFilename[$key])

or error('receiving directory insuffiecient permission', $uploadForm);

}

 

// If you got this far, everything has worked and the file has been successfully saved.

// We are now going to redirect the client to the success page.

header('Location: ' . $uploadSuccess);

 

// make an error handler which will be used if the upload fails

function error($error, $location, $seconds = 5)

{

header("Refresh: $seconds; URL=\"$location\"");

echo '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"'."\n".

'"http://www.w3.org/TR/html4/strict.dtd">'."\n\n".

'<html lang="en">'."\n".
