[SOLVED] Upload Script Platform Issues

[NeTech-UK]

Hi all,

alas my first post be a problem I have been working on an image upload script and so far it all seems to be working.... in firefox. Problem is as soon as I attempt an upload in internet explorer the file handler errors out and defines the file as an unsupported upload. Cross browser compatibility is of course very important in this script.

I enclose the code for my file handler. any help would be appreciated...

 

filehandler.php

<?php
$baseurl = "http://portfolio.netech-uk.com/imageupload";
$description = $_POST['description'];
if (!($description))
{
$description = "No Description";
}
$description = nl2br($description);

//Error #1: No File Specified
//Error #2: File Already Exists
//Error #3: Unspecified Error Occured
//Error #4: Invalid File Specified

//check that we have a file

include 'includes/configandconnect.php';




if((!empty($_FILES["uploaded_file"])) && ($_FILES['uploaded_file']['error'] == 0)) {

	 //Check if the file is JPEG image and it's size is less than 1Mb
  	$filename = basename($_FILES['uploaded_file']['name']);
  	$ext = substr($filename, strrpos($filename, '.') + 1);

  	if (($_FILES["uploaded_file"]["type"] == "image/jpeg") && ($_FILES["uploaded_file"]["size"] < 1024000)) 
{

    //Determine the path to which we want to save this file
    	 	$newname = dirname(__FILE__).'/files/'.$filename;
	$link = "$baseurl/files/$filename";
	$filesize = $_FILES["uploaded_file"]["size"];
	$filetype = $_FILES["uploaded_file"]["type"];
	$uploaderip = $_SERVER['REMOTE_ADDR'];
	$date = date("l jS F Y");
	$time = date("H:i");

     		//Check if the file with the same name is already exists on the server
      		if (!file_exists($newname)) 
	{

        		//Attempt to move the uploaded file to it's new place
        		if ((move_uploaded_file($_FILES['uploaded_file']['tmp_name'],$newname))) 
		{
			mysql_query("INSERT INTO imageupload_images VALUES('', '$filename', '$filesize', '$date', '$time', '$ext', '$link', '$description', '$uploaderip')");

			$getdata = mysql_query("SELECT * FROM imageupload_images WHERE filename = '$filename'");
			while ($data = mysql_fetch_array($getdata))
			{
				$id = $data['id'];
			}

			include 'includes/disconnect.php';
           			Header("Location: result.php?id=$id");
        		} 
		else 
		{
			include 'includes/disconnect.php';
			Header("Location: result.php?status=3");
        		}
      		} 
	else 
	{
			include 'includes/disconnect.php';
			Header("Location: result.php?status=2");
      		}
  	} 
else 
{
	include 'includes/disconnect.php';
	Header("Location: result.php?status=4");
  	}
} 
else 
{
include 'includes/disconnect.php';
Header("Location: result.php?status=1");
}
?>

well...instead of doing doing the redirect, echo the value of $_FILES["uploaded_file"]["type"] so you can see what it is...my guess is it's image/pjpeg

Thank you so much rhodesa, the problem was exactly what you thought it was

[rhodesa]

yeah...IE is stupid and uploads stuff as a "Progressive JPEG"....if you want to make your script a little more flexible it should be safe to just check the first part of the mime-type to see if it's an 'image' or not. Another way to check (GD needs to be supported) is to use getimagesize(). If it returns false, it's not a supported image.
