Copy of image -> smaller

["Gustav Wiberg" <gustav@xxxxxxxxxxxxxx>]

Hi there!

When I upload a picture from a form, then I want to create a copy with a 
smaller image.
For example: I upload a picture with dimensions 200x150 name 4.jpg. I also 
want a copy of this image but with the dimensions 100x75 pixels. I've tried 
this below, but I'm missing something I think... :-)

I'm using PHP 4.x  (don't know exactly the vers.nr, but I can search for it 
if it is of importance)

The code down below is a function for uploading a picture. The part I want 
help with is after the comment: //What should/could I do here?

Best regards
Gustav Wiberg



<?php
function uploadPic($idUpload, $picUpload, $addUpload, $copyFile, $toPath) {

  //Upload chosen file to upload-map (
  //
  if (strlen($_FILES[$picUpload]['name'])>0)
  {
  //ECHO "yes! ID=$idUpload PIC=$picUpload ADD=$addUpload<br>";
  $uploaddir = dirname($_FILES[$picUpload]['tmp_name']) . "/";

  //Replace .jpeg to .jpg
  //
  $_FILES[$picUpload]['name'] = 
str_replace(".jpeg",".jpg",$_FILES[$picUpload]['name']);

  //Get first 4 last characters of uploaded filename
  //
  $ble = strtolower(substr($_FILES[$picUpload]['name'], -4, 4));

  //Move to path $toPath (followed by what to add after file (that is sent 
to this function)) and ext.)
  //
  $mfileAdd = $idUpload . $addUpload . $ble;

  move_uploaded_file($_FILES[$picUpload]['tmp_name'], $toPath . $mfileAdd);


  //echo "mfileAdd=$mfileAdd<br><br>";
  //Set appropiate rights for file
  //
  //echo "FILE TO TEST=$mfileAdd";
  chmod($toPath . $mfileAdd, intval('0755', 8));


  //Copy this file to another file?
  //
  if (strlen($copyFile)>0) {
  $mfile = $idUpload . $copyFile . $ble;
  //echo "MFILE=$mfile";
  copy($toPath . $mfileAdd, $toPath . $mfile);
  chmod($toPath . $mfile, intval('0755', 8));
  }


//What should/could I do here?
//

           //Set new width and height
           //
          $new_width = 100;
          $new_height = 200;
          $tmp_image=imagecreatefromjpeg($toPath . $mfileAdd);
          $width = imagesx($tmp_image);
          $height = imagesy($tmp_image);
          $new_image = imagecreatetruecolor($new_width,$new_height);
           ImageCopyResized($new_image, $tmp_image,0,0,0,0, $new_width, 
$new_height, $width, $height);

           //Grab new image
           ob_start();
           ImageJPEG($new_image);
           $image_buffer = ob_get_contents();
           ob_end_clean();
           ImageDestroy($new_image);

           //Create temporary file and write to it
           $fp = tmpfile();
           fwrite($fp, $image_buffer);
           rewind($fp);

           //Upload new image
           $copyTo = 'http://www.ledins.se/test.jpg';
           $conn_id = ftp_connect('<domain>');
           ftp_login($conn_id,'<username for domain>','<password>');
           ftp_fput($conn_id, $copyTo, $fp, FTP_BINARY);
           fclose($fp);



  //Return the filename created based on productID
  //
  return $mfileAdd;
  }
