Uploading in PHP

[angst]

ok, I've found a nice little script for uploading, and it does work.
but i have two questions about this script

PHP Code:


<?php

    $uploadpath = 'C:/Program Files/Apache Group/Apache2/htdocs/pics/images/';
    $source = $HTTP_POST_FILES['file1']['tmp_name'];
    $dest = '';

    if ( ($source != 'none') && ($source != '' )) {

        $imagesize = getimagesize($source);

        switch ( $imagesize[2] ) {

            case 0:

                echo '<BR> Image is unknown <BR>';
                break;

            case 1:
                echo '<BR> Image is a GIF <BR>';
                $dest = $uploadpath.uniqid('img').'.gif';
                break;

            case 2:
                echo '<BR> Image is a JPG <BR>';
                $dest = $uploadpath.uniqid('img').'.jpg';
                break;

            case 3:
                echo '<BR> Image is a PNG <BR>';
                $dest = $uploadpath.uniqid('img').'.png';
                break;

        }

        if ( $dest != '' ) {

            if ( move_uploaded_file( $source, $dest ) ) {

                echo 'File successfully stored.<BR>';

            } else {

                echo 'File could not be stored.<BR>';

            }

        }

    } else {

        echo 'File not supplied, or file too big.<BR>';

    }

?>

First, this script uploading the file with a uniqid, what i want to know is how can i get this id while i'm uploading, so i can add the picture name to the db?

also it looks like this script allows files to be limited by size, but i don't see how to set the size limit. any ideas?

thanks in advance for your time!

For the uniqid question, simply give it a variable instead:

PHP Code:


$unique_id = uniqid('img');
$dest = $uploadpath . $unique_id . '{TYPE}'; 


$unique_id is now carrying your uniqid value.
As for your size, I don't see it implimented anywhere within the script. Implimentation would be extremely simple to do for you though, specify yourself a hardcoded or php variable -> do not rely on MAX_FILE_SIZE.

PHP Code:


$max_upload_size = 1024;  // 1kb, yeah I know... small lol.

if (($source != 'none' && $source != '' ) AND $_FILES['file1']['size'] <= $max_upload_size) { 
/*processing code follows */ 


Hope that helps. Oh, btw, change your $HTTP_POST_FILES to $_FILES. Unless of course your php version is less than 4.1.0. Then leave it.
