Images

[harkly]

I have a form that allows for 5 images to be uploaded. They will then be renamed and the name will be put in the db. How do I get it not to run if an image is not selected?

I want to be able to skip the process if no image is selected.

$userID="test";

include('library/login.php');
login();
mysql_select_db('test);


if ($photo_1 != 'null')
  {

  $extension = strrchr($_FILES['photo_1']['name'],'.');  

  $extension = strtolower($extension); 

  $photoNumber="_1";

  $finalName="$userID$photoNumber";


  $save_path = "uploads/";

  $target_path = $save_path . basename( $_FILES['photo_1']['name']); 

  $NewPhotoName = $finalName; 

  $withExt = $NewPhotoName . $extension;

  $filename = $save_path . $NewPhotoName . $extension; 

  if(move_uploaded_file($_FILES['photo_1']['tmp_name'], $filename)) {

  $query = "UPDATE photos SET photo_1='$withExt' WHERE userID='$userID'";

  $result = mysql_query($query) or die(mysql_error());

  } else{
    echo "Error Uploading";
  }

  }

I am not 100% how images are handled.

this is all the basic on moving uploaded files, filters for no files uploaded, possible hack attacks, and folder permissions not being set right..

if(count($_FILES)){
   foreach($_FILES as $file){
      if($file['err'])continue;
      if(!is_uploaded_file($file['tmp_name'])){
         //notify of error by email perhaps
         continue;
      }
      if(!move_uploaded_file($file['tmp_name'], '/your/path/' . $file['name'])){
         //error, unable to move file, permissions problem maybe?
         continue;
      }
      echo 'file '.$file['name'].' uploaded<br />';
   }
}
