Re: [PHP] Validate if the field of a form is empty

2010-07-13 Thread te0t3l 
It works fine for me,

foreach ( $_FILES['archivo']['name'] as $file ) {
   //echo $file;
}
if($file == ""){
echo "empty";
}else{
   //continue...
}

Thanks a lot Jim!

To see what is happening, look at the output of print_r($_FILES);

But, you should be doing it like this.

foreach ( $_FILES["archivo"] AS $file ) {
  $field = $file['name'];
  ...
}
