Hi
I have a multiple-query issue I'd like some advice and help with.
I am trying to create a website, in which users can upload their own images to the site.
I am a beginning in PHP (and only solid in html and some sql querying)
What I think I need to be able to do is the following:
1. Enable the user to upload images to be stored in a folder on the server.
2. A location URL to also be uploaded (with other parts of the form data) to a database table.
3. Some way to have the folder create a new name for itself each time a new user uploads imags - and for the folder to connect to the database record for that user.

I do not want the images to immediately show on the webpage on uploading.
I seem to be able to create scripts which can either store the image in the folder, or store the image in the database (which I dont' want) or to just simply upload the URL to the database . I can't seem to have the upload.php script do what I want above.

The script below is called from a simple form I have which allows upto x number of pics to be selected from the User's file directory.

Any help on how I can start to go about understanding how to make the upload function do the above - or indeed if there is a simpler way? Then I would be very grateful.....
Many thanks

<?php
//set where you want to store files
//in this example we keep file in folder upload 
//$HTTP_POST_FILES['ufile']['name']; = upload file name
//for example upload file name cartoon.gif . $path will be upload/cartoon.gif
$path1= "upload/".$HTTP_POST_FILES['ufile']['name'][0];
$path2= "upload/".$HTTP_POST_FILES['ufile']['name'][1];
$path3= "upload/".$HTTP_POST_FILES['ufile']['name'][2];

//copy file to where you want to store file
copy($HTTP_POST_FILES['ufile']['tmp_name'][0], $path1);
copy($HTTP_POST_FILES['ufile']['tmp_name'][1], $path2);
copy($HTTP_POST_FILES['ufile']['tmp_name'][2], $path3);

This is an old function I used to use. Not sure how helpful it will be, but at least it shows how to give the image a unique name using time():

<?php

define("MAX_SIZE","100");

$errors = 0;

if (isset($_POST['upload'])) {
	$image = $_FILES['image']['name'];
		
	if ($image) {
		$filename = stripslashes($_FILES['image']['name']);
		$extension = getExtension($filename);
		$extension = strtolower($extension);
			
		if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "gif") && ($extension != "png")) {
			$errors = 1;
			echo 'wrong extension';
		}
		else {
			$size = filesize($_FILES['image']['tmp_name']);
		
				if ($size > MAX_SIZE*1000) {
					$errors = 1;
					echo 'Sorry, the image is too large, Please specify another';
				}		
			//give unique name to image
			$image_name = time().'.'.$extension;
			$newname = "images/".$image_name;
			
			$copied = copy($_FILES['image']['tmp_name'],$newname);
			$_SESSION['img'] = $newname;

				if (!$copied) {
					$errors = 1;
				} 
		}
	}
}

//--- DETERMINES IMAGE EXTENSION ---//
function getExtension($str) {
	$i = strrpos($str,".");
		if (!$i) {
			return "";
		}
	$l = strlen($str)-$i;
	$exten = substr($str,$i+1,$l);
	return $exten;
}
?>
