well i nearly done my dissertation now 2 more days of hard writting. Maybe another 40 pages or so

But I thought you might wanna check out my upload jpeg upload script cause i love it:
oh you can obviously upload several images at ones cause I am using an array for the html input: <input type='file' name='images[]' /> see here images is an array.

PHP Code:


			
<?php

session_start();

require_once('../image_fns.php');

$conn = db_connect();



while(list($key,$value) = each($_FILES[images][name])) //Loops through the uploaded array of Images

{

    if(!empty($value))// this will check if any blank field is entered

    {   

        if($_FILES[images][type][$key] == "image/jpeg") //This checks that the uploaded image is a jpeg file

        {

                $filename = $value;    // filename stores the value

                $userdir = $_SESSION['valid_user']; //The user who currently is logged in

                $scrUserName = $userdir;

                $uploaddir = 'images/'.$userdir.'/';   // upload directory path is set

                @mkdir ($uploaddir,666); //Create directory

                $randomnumber =rand(); //create random number

                $srcFilename = $_FILES[images][name][$key]; //name of Image

                $srcName = $randomnumber.$_FILES[images][name][$key]; //new name of image with random number in front of it

                $uploadedfile = $uploaddir . $srcName;  //the path and name of the uploaded file

                $src = $uploadedfile;

                if (copy($_FILES[images][tmp_name][$key], $uploadedfile))  //  upload the file to the server and if successfull

                {

                    $thuName = $srcFilename. "thumb.jpg"; //create thumbnail name

                    $desttemp = $uploadedfile . "thumb.jpg"; //thumbnail directory and name.

                    $dest = $desttemp;

                    //Set some variables for thumb creation

                    $maxWidth = "180";

                    $maxHeight = "180";

                    $quality = "90";

                    

                        if (file_exists($src) && isset($dest))  // if the uploaded image was copied to the user image directory

                         {

                                // Returns information about a file path

                                $destInfo = pathInfo($dest); 

                                // Put information into variables for DB insert

                                //Gets the image dimensions its an array

                                $srcSize = getImageSize($src);    

                                //with and height

                                $srcHeight = $srcSize[1];

                                $srcWidth = $srcSize[0];

                                //todays date

                                $srcUploaddate = date("Y-m-d");

                                //Gets image size in bytes    

                                $srcBytes = filesize($src);

                                $srcPath = $src;

                                

                                $srcSize = getImageSize($src);                    

                                // $destSize[0] = width, $destSize[1] = height

                                $srcRatio = $srcSize[0] / $srcSize[1]; // width/height ratio

                                $destRatio = $maxWidth / $maxHeight;

                                //Maths for thumb creation

                                if ($destRatio > $srcRatio) {

                                    $destSize[1] = $maxHeight;

                                    $destSize[0] = $maxHeight * $srcRatio;

                                } else {

                                    $destSize[0] = $maxWidth;

                                    $destSize[1] = $maxWidth / $srcRatio;

                                } 

                                //Create new truecolour image

                                $destImage = imagecreatetruecolor($destSize[0], $destSize[1]);

                                //Make sure the new image is antialiased

                                imageantialias($destImage, true);     

                                //Created a new Image from the source                             

                                $srcImage = imagecreatefromjpeg($src);

                                // Copy and resize part of an image with resampling (create thumbnail)

                                imagecopyresampled($destImage, $srcImage, 0, 0, 0, 0, $destSize[0], $destSize[1], $srcSize[0], $srcSize[1]); 

                                // Output image to file

                                imagejpeg($destImage, $dest, $quality);

                                $thuPath = $dest;

                                $result = $conn->query("insert into Image (User_Name,Image_Size,Image_DisplayName,Image_Name,Image_Path,Image_UploadDate,Image_Thumbpath,Image_ThumbName,Image_Height,Image_Width)

                                                                     values('$scrUserName',$srcBytes,'$srcFilename', '$srcName','$src','$srcUploaddate','$thuPath','$thuName',$srcHeight,$srcWidth)");

                                  if (!$result)

                                  echo 'Could not store images in database - please try again later.';

                                            

                        } 

                

                }

        }

           

    }

$_SESSION['UPLOADED']=true;
