I know ASP, not PHP.

That being said, I have a PHP script that works fine after I post user input, however, the script runs when the page loads before the user input can be submitted...so I get an error. How do I prevent the code from running before the user input is posted?

Thank you to anyone who can help.

Without seeing the page code, no certainty, but you probably have the form and the processing code in the same page.

In that case, you must enclose the processing code into a block to activate it only when the form is posted

PHP Code:

<?php
if sizeof($_POST)>0{
  //...handle the post processing here
}

//put the page code here

Test for whether user input exists and execute the desired code block only if the condition is met. In pseudo code:

IF {user has posted data}
  {process user data}
END IF
{show page content}

I edited the post because your script worked (kind of). Thanks tripy!
I used

if(isset($_POST["curl"])>0){ 
  //...handle the post processing here

Is this eceptable, or is "isset" uneeded? Thanks again!

Actually I think the > 0 is uneeded. isset returns a boolean so comparing it with 0 is unnecessary. You can simplify your condition like this:

PHP Code:

if(isset($_POST['curl']))
{
.
.
.
}

Thanks! This makes sense and works perfectly. I hate useless/redundant code...so thank you.
