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

[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'];
  ...
}

Re: [PHP] validate + if

[Richard Lynch]

If your "onClick" handler returns true (or is it false?) in JS, the
action won't happen.

Or something like that.

Google for it.

And you still need to validate server-side, as JS is easily bypassed.

Return false from the form validation if it fails and call if with the form's 
onSubmit function
 

 
returning false will stop the submission
