[RESOLVED] Get each $_FILES form field name?

[HCBen]

Is there a way to extract the form field name along with the file name out of $_FILES?

I see the form field name associated with each file array when I dump $_FILES with print_r for example, but I'm stumped as to how to extract those along with the actual file name.

When I find an error with a certain file (wrong file type or something) I want to alert the user of the error which includes the form field name along with the actual file name. This will help in identifying particular form fields when using a form with many file upload fields.

For example, if I have a file upload form field named="Essay" (or if using an array ="files[Essay]"), I'd like to inform the user of that form field in my error message. I've got every aspect of the file upload process working, I'm just stumped with trying to get the form field name.

Anyone done this before or know how? I'd appreciate any help.

Thanks,
Ben

hmm... but in order to access the file data from the $_FILES array you need to know the field name, so you should already have the field name available.

I figured it out by accident (and it was so simple): assign the $_FILES super to a local variable.

For example:

$files = $_FILES;

foreach ($files as $field_name => $val)
{
   $field_name; // contains the form field name;
   $files[$field_name]['name']; // contains the file name.
}

Then again

foreach($_FILES as $field_name => $val)
{
  // $field_name contains the form field name
  // $_FILES[$field_name]['name'] contains the file name
}

Then there's [man]array_keys/man....
