Checking a file upload field isn't empty

[graham23s]

Hi Guys,

 

i have googled this and haven't seen anything, basically i can get the normal input field validations correct, but not sure how to check if an upload filed actually has a file in it or not

 

code so far:

 

function validate_uploads()
{  
  if (document.upload_form.file.value == "")
  {
  alert("You never selected a file for uploading!");
  return false;
  }
  if (document.upload_form.file_name.value == "")
  {
  alert("You never entered a name for the file!");
  return false;
  }
  
  // else return true //
  return true;
}

 

i thought it would be the name of the input filed but nope lol

 

any help would be great

 

cheers

i dont know if theres a way of doing that

without actually uploading the file and then

checking the size with a language like PHP,

ASP, or ASP.NET

I think this prob does need serverside scripting. Would it be possible with some kind of ajax script. I usually make a seperate page for uploading images and text fields this is the way it is usually done on any site. But it would be nice to have it all in one form and validate it all at once
