sorting out null files in multiple upload submissions.

[phpmike]

hey there... I currently have a multiple upload form that handles my file uploading. It defaults to 8 boxes. But when I go to upload the information say I use only 4 of the boxes and then the other 4 still try to upload. I am using count to get the 4 loop on the array.

here is the code that the forms hit... keep in mind the the array containing the files is fu.

  require("upload.php");
    $np = count($fu);
    for($x=0; $x < $np; $x++) {
      $size = getimagesize($_FILES['fu']['tmp_name'][$x]);
      require("db.php");
      $dbc = mysql_connect($dbcon, $dbusr, $dbpas);
      mysql_select_db($dbsel, $dbc);
      if(@!$size[2] == 2) { die(); }
      if($x == 0) { if(!copySizedUploadMain($_FILES['fu']['tmp_name'][$x], "E:\listingphotos\\$PrID-$x.jpg", 425, 425, "$ca[$x]", $size, $PrID, $ClID, $x))
       die("Images Failed To Upload"); }
      else {
        if (!copySizedUpload($_FILES['fu']['tmp_name'][$x], "E:\listingphotos\\$PrID-$x.jpg", 425, 425, "$ca[$x]", $size, $PrID, $ClID, $x))
         die("Images Failed To Upload"); }
      mysql_close($dbc);
      header("cl_main.php?ClID=$ClID");
    }
    exit;
  }

I also tried this for loop but got no where... help!

    for($y=0; $y<=$np; $y++) {
      if ($_FILES['fu'][$y] == $null) {
        $cp = $y;
      }
      else {
        if ($y == $np) {
        $cp = $y;
        }
      }
    }

Use the forach construct.

That way it will only actually try and upload the files that have values in the array

here's my code for my multiple upload form

function PERFORM_upload($gal_id='')
		{
			$this->dir = _IMAGES_LOCATION;
			$this->upload_files = $_FILES['userfile'];

		if($this->handle = @opendir($this->dir))
		{
			foreach($this->upload_files['name'] as $k => $v)
			{
				$this->image_details = pathinfo($this->upload_files['name'][$k]);

				$this->upload_files['name'][$k] =(($_POST['user_supplied_name'][$k])?$_POST['user_supplied_name'][$k].".".$this->image_details['extension']:$this->upload_files['name'][$k]);

				if(!file_exists($this->dir.$this->upload_files['name'][$k]))
				{
					if(!is_writeable($this->dir.$this->upload_files['name'][$k]))
					{
						if(move_uploaded_file($this->upload_files['tmp_name'][$k],$this->dir.$this->upload_files['name'][$k]))
						{
							$this->message .="Successfully uploaded <b>".$this->upload_files['name'][$k]."</b><br>";

							$this->image_name = basename($this->upload_files['name'][$k]);
							$this->user_supplied_comment = trim(addslashes(($_POST['user_supplied_comment'][$k])?$_POST['user_supplied_comment'][$k]:'No Comment!!!!'));
							$this->path = $this->dir;
							$this->image = GetImageSize($this->dir.$this->upload_files['name'][$k]);
							$this->real_width = $this->image[0];
							$this->real_height = $this->image[1];
							$this->type = $this->image[mime];
							$this->file_size = stat($this->dir.$this->upload_files['name'][$k]);
							$this->physical_size = $this->file_size[7];

							if($this->physical_size > 1023)#Work out which extension to give the image
							{
								$this->physical_size = ($this->physical_size)/1024;
								$this->filesize_ext = (($this->physical_size >1048567)?(($this->physical_size)/1024)."MBytes":"KBytes");
							}else{
								$this->filesize_ext = "Bytes";
							}

							/* Now put the image details into the database */
							$db = new Database();
							$db->run_query("INSERT INTO images(id,name,path,width,height,type,filesize,filesize_ext) VALUES('','$this->image_name','$this->path','$this->real_width','$this->real_height','$this->type','$this->physical_size','$this->filesize_ext')");
							$inserted_image_id = mysql_insert_id();
							$db->run_query("INSERT INTO gallery_contents (image_id) VALUES ('$inserted_image_id')");

							if($this->gal_id !=$this->default_gal)
							{
								$record_to_amend = mysql_insert_id();
								$db->run_query("UPDATE gallery_contents set gallery_id ='$this->gal_id' WHERE id='$record_to_amend'");
							}

							$db->run_query("INSERT INTO
										COMMENTS
											(id,
											 image_id,
											 gallery_id,
											 comment)
										VALUES
											('',
											 '$inserted_image_id',
											 '$this->gal_id',
											 '$this->user_supplied_comment'
											 )");

							/*Now we will create the thumbnail 
							$this->image = new ImageMagick($this->dir.$this->upload_files['name'][$k]);

							if($image->imageHeight > $image->imageWidth)
							{
								$proportion = $imageHeight / _DEFAULT_THUMB_WIDTH;
							}else{
								$proportion = $imageWidth /  _DEFAULT_THUMB_WIDTH;
							}

							$newWidth = ($image->imageWidth / $proportion);
							$newHeight = ($image->imageHeight / $proportion);
							$image->c_resize($this->dir.'thumb_'.$this->upload_files[$k],$newWidth,$newHeight);
*/
								/* end of thumbnail creation */
							}else{

							$this->message = $this->upload_files['name']['error'][$k];
						}

						clearstatcache();
					}

				}else{

					if(!empty($this->upload_files['name'][$k]))
					{
						$this->message .= "<h3>ERROR</h3> file ".$this->upload_files['name'][$k]." exists<br>";
					}

				}
			}
			return $this->message;
		}else{
			$this->message = "Cannot upload file to $this->dir<br>";
			return ($this->message);
		}
		closedir($this->handle);
