<html>
<head>
<title></title>
<?php


//load the config file
include("config.php");

//if the for has submittedd
if (isset($_POST['upForm'])){

       $file_type = $_FILES['imgfile']['type'];
       $file_name = $_FILES['imgfile']['name'];
       $file_size = $_FILES['imgfile']['size'];
       $file_tmp = $_FILES['imgfile']['tmp_name'];
   $Box = $_POST['Box'];
   $CAR_ID = $_GET['ID'];

       //check if you have selected a file.
       if(!is_uploaded_file($file_tmp)){
          echo "Error: Please select a file to upload!. <br>--<a href=\"$_SERVER[php_SELF]\">back</a>";
          exit(); //exit the script and don't do anything else.
       }
       //check file extension
       $ext = strrchr($file_name,'.');
       $ext = strtolower($ext);
       if (($extlimit == "yes") && (!in_array($ext,$limitedext))) {
          echo "Wrong file extension.  <br>--<a href=\"$_SERVER[php_SELF]\">back</a>";
          exit();
       }
       //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);
       //get the new width variable.
       $ThumbWidth = $img_thumb_width;

       //keep image type
       if($file_size){
          if($file_type == "image/pjpeg" || $file_type == "image/jpeg"){
               $new_img = imagecreatefromjpeg($file_tmp);
           }elseif($file_type == "image/x-png" || $file_type == "image/png"){
               $new_img = imagecreatefrompng($file_tmp);
           }elseif($file_type == "image/gif"){
               $new_img = imagecreatefromgif($file_tmp);
           }
           //list width and height and keep height ratio.
           list($width, $height) = getimagesize($file_tmp);
           $imgratio=$width/$height;
           if ($imgratio>1){
              $newwidth = $ThumbWidth;
              $newheight = $ThumbWidth/$imgratio;
           }else{
                 $newheight = $ThumbWidth;
                 $newwidth = $ThumbWidth*$imgratio;
           }
           //function for resize image.
           if (function_exists(imagecreatetruecolor)){
           $resized_img = imagecreatetruecolor($newwidth,$newheight);
           }else{
                 die("Error: Please make sure you have GD library ver 2+");
           }
           imagecopyresized($resized_img, $new_img, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
           //save image
           ImageJpeg ($resized_img,"$path_thumbs/$rand_name.$file_ext");
           ImageDestroy ($resized_img);
           ImageDestroy ($new_img);
           //print message
           echo "<br>Image Thumb: <a href=\"$path_thumbs/$rand_name.$file_ext\">$path_thumbs/$rand_name.$file_ext</a>";
        }

        //upload the big image
        move_uploaded_file ($file_tmp, "$path_big/$rand_name.$file_ext");

        echo "<br>Image Big: <a href=\"$path_big/$rand_name.$file_ext\">$path_big/$rand_name.$file_ext</a>";

        echo "<br><br>--<a href=\"$_SERVER[php_SELF]\">back</a>";

SO for shure in the form i need to add 2 more image  file fields.called the imagefile2,imagefile3.since the first one is called imagefile.

 

them im almost shure i need to add this

$file_type3 = $_FILES['imgfile2']['type'];

      $file_name2 = $_FILES['imgfile2']['name'];

      $file_size2 = $_FILES['imgfile2']['size'];

      $file_tmp2 = $_FILES['imgfile2']['tmp_name'];

 

  $file_type 3= $_FILES['imgfile3']['type'];

      $file_name 3= $_FILES['imgfile3']['name'];

      $file_size 3= $_FILES['imgfile3']['size'];

      $file_tmp3 = $_FILES['imgfile3']['tmp_name'];

 

 

To get the other images.

 

Afther:

  $ext = strrchr($file_name,'.');

to

 

$ext = strrchr($file_name,$file_name2,$file_name3,'.');

 

and

$getExt = explode ('.', $file_name);

 

to

 

$getExt = explode ('.', $file_name,$file_name2,$file_name3);

 

Afther im lost...is this good up to know?

its all good but the thumbs dont work?

 

<?php
