[SOLVED] PHP - Process page, then check if empty

[Gamerz]

Hello,

I have a php file uploader that has the form and php processing upload script embellished on the same script...I was wonder, how I can check if the user has uploaded a file, and if it hasn't, the script will die.

 

So far, I have this:

// If the $_FILES global IS INDEED empty and the password is set, continue
if (empty($_FILES['userfile']['name'])) {
   echo '$var is either 0, empty, or not set at all';
}

 

The code is indeed correct, but the thing is, since it's all in one script...the php checks if the $_FILES is empty...and obviously when you first go to my script, it will obviously provide the die error, since you havent uploaded any file...

Then you need to check to see if the form has been submitted before applying that check.

How do I check if the form is submitted?

There's a submit button in your form that the user clicks on it to upload his file. It looks like this:

 

<input type="submit" name="submitButton" value="upload file" />

 

To check if the form has been submitted:

 

if (isset($_POST['submitButton']))
{
if (empty($_FILES['userfile']['name'])) {
   echo '$var is either 0, empty, or not set at all';
}
}
