In short, it manages the uploaded file, - * and allows you to do whatever you want with the file, especially if it - * is an image, and as many times as you want. - * - * It is the ideal class to quickly integrate file upload in your site. - * If the file is an image, you can convert, resize, crop it in many ways. - * You can also apply filters, add borders, text, watermarks, etc... - * That's all you need for a gallery script for instance. Supported formats - * are PNG, JPG, GIF and BMP. - * - * You can also use the class to work on local files, which is especially - * useful to use the image manipulation features. The class also supports - * Flash uploaders. - * - * The class works with PHP 4 and 5, and its error messages can - * be localized at will. - * - * How does it work? - * - * You instanciate the class with the $_FILES['my_field'] array - * where my_field is the field name from your upload form. - * The class will check if the original file has been uploaded - * to its temporary location (alternatively, you can instanciate - * the class with a local filename). - * - * You can then set a number of processing variables to act on the file. - * For instance, you can rename the file, and if it is an image, - * convert and resize it in many ways. - * You can also set what will the class do if the file already exists. - * - * Then you call the function {@link process} to actually perform the actions - * according to the processing parameters you set above. - * It will create new instances of the original file, - * so the original file remains the same between each process. - * The file will be manipulated, and copied to the given location. - * The processing variables will be reset once it is done. - * - * You can repeat setting up a new set of processing variables, - * and calling {@link process} again as many times as you want. - * When you have finished, you can call {@link clean} to delete - * the original uploaded file. - * - * If you don't set any processing parameters and call {@link process} - * just after instanciating the class. The uploaded file will be simply - * copied to the given location without any alteration or checks. - * - * Don't forget to add enctype="multipart/form-data" in your form - * tag
if you want your form to upload the file. - * - * How to use it?
- * Create a simple HTML file, with a form such as: - * 
- * 
- *   
- *   
- * 
- *
- * Create a file called upload.php: - * 
- *  $handle = new upload($_FILES['image_field']);
- *  if ($handle->uploaded) {
- *      $handle->file_new_name_body   = 'image_resized';
- *      $handle->image_resize         = true;
- *      $handle->image_x              = 100;
- *      $handle->image_ratio_y        = true;
- *      $handle->process('/home/user/files/');
- *      if ($handle->processed) {
- *          echo 'image resized';
- *          $handle->clean();
- *      } else {
- *          echo 'error : ' . $handle->error;
- *      }
- *  }
- *
- * - * How to process local files?
- * Use the class as following, the rest being the same as above: - * 
- *  $handle = new upload('/home/user/myfile.jpg');
- *
- * - * How to set the language?
- * Instantiate the class with a second argument being the language code: - * 
- *  $handle = new upload($_FILES['image_field'], 'fr_FR');
- *  $handle = new upload('/home/user/myfile.jpg', 'fr_FR');
- *
- * - * How to output the resulting file or picture directly to the browser?
- * Simply call {@link process}() without an argument (or with null as first argument): - * 
- *  $handle = new upload($_FILES['image_field']);
- *  header('Content-type: ' . $handle->file_src_mime);
- *  echo $handle->Process();
- *  die();
- *
- * Or if you want to force the download of the file: - * 
- *  $handle = new upload($_FILES['image_field']);
- *  header('Content-type: ' . $handle->file_src_mime);
- *  header("Content-Disposition: attachment; filename=".rawurlencode($handle->file_src_name).";");
- *  echo $handle->Process();
- *  die();
- *
- * - * Processing parameters (reset after each process) - * - * - * The following eight settings can be used to invalidate an upload if the file is an image (note that open_basedir restrictions prevent the use of these settings) - * - * - * The following variables are used only if {@link image_resize} == true - * - * Use either one of the following - * - * The following image manipulations require GD2+ - * - * - * - * - * - * - * - * Values that can be read before calling {@link process}() - * - * If the file is a supported image type (and open_basedir restrictions allow it) - * - * - * Values that can be read before after {@link process}() - * - * If the file is a supported image type - * - * - * Requirements - * - * Most of the image operations require GD. GD2 is greatly recommended - * - * The class is compatible with PHP 4.3+, and compatible with PHP5 - * - * Changelog - * - * - * @package cmf - * @subpackage external - */ -class upload { - - - /** - * Class version - * - * @access public - * @var string - */ - var $version;
