Random Name

[Julian]

Hi Guys!

 

I have this script to generate a random name when I upload a file to my server:

 

$file_temp_dir = "../fotos";

//Random name

	$file_name = $_FILES['userfile']['name'];

	   //get the file extension.
       $getExt = explode ('.', $file_name);
       $file_ext = $getExt[count($getExt)-1];

       //create a random file name
       $rand_name = md5(time());
       $rand_name= rand(0,999999999);

if (($userfile!="none")&&($userfile!="")) {
		move_uploaded_file($userfile, "$file_temp_dir/$rand_name.$file_ext");
    }
     else
{
$filename = $HTTP_POST_VARS['imagen'];
} 

 

What I want to do is reuse this script when I upload 3 or 4 files without adding the script 3 or 4 times.  I think if I use as a function but I'm newbie on this.  Any help will be appreciated. 

 

Thanks guys!

So what's the problem with it?

 

Only one thing I noticed:

This-

$rand_name = rand(0,999999999);

Should be-

$rand_name .= rand(0,999999999);

 

 

Orio.

Here's the problem:

 

$file_name = $_FILES['userfile']['name'];

 

How do I do if I want to post different files as userfile2, userfile3?

 

Thanks

if you need to post more then one file you need to use an array on the form name='go[]' ok

I think I'm not explaining right.

 

The form I have upload 5 files to the server, and saves the info (of the file names) into a database.

 

Without the random name I upload the "real" name of the file, but if somebody name the file as one on the server it will replace the one on the server.  That's why I'm trying to insert a random name, so it will be hard to create an exact name.

 

<input type="file" name="userfile">

<input type="file" name="userfile2">

<input type="file" name="userfile3">... and so on.

 

How can I use only this script one time to process all the files?  Thanks

Any hint, guys?  I'm hitting my head trying to resolve this....  Thanks

<?php

function randName($file) {
$file_temp_dir = "../fotos";
//Random name
$file_name = $file['name'];

    //get the file extension.
    $getExt = explode ('.', $file_name);
    $file_ext = $getExt[count($getExt)-1];

    //create a random file name
    $rand_name = md5(time());
    $rand_name= rand(0,999999999);

if (($file!="none")&&($file!="")) {
	move_uploaded_file($file, "$file_temp_dir/$rand_name.$file_ext");
    }else {
	$filename = $HTTP_POST_VARS['imagen'];
}
}

foreach ($_FILE as $key => $val) {
randName($val);
}

?>

 

Is that what you are looking for?

Great Frost, Thanks.  I think you got it.

 

The only thing missing here is:

 

}else {
	$filename = $HTTP_POST_VARS['imagen'];

 

In case nothing is uploaded, I just keep the old files on the database.  I'm doing this with hidden tag and then $HTTP_POST_VARS the filename.  Thanks for the great help!
