Question

I’m working a web application with PHP.
Something wrong is happening that I have never seen before. $_GET is working well, but $_POST does not work exactly. Imagine the form below:

<form action="process.php" method="post">
   <input type="text" name="title" />
   <input type="submit" value="send" />
</form>

As you see, I’ve used post for method attribute of the form. In this case, the code below will return error:

<?php
$sentData = $_POST['title'];
echo($sentData);    
?>

Error message:

PHP Notice:  Undefined index: title in ...

But If I had used $_GET in php scripts and get in the html form codes, everything would work without any error.

There are something more strange.

1. There are just one form that returns no error while I’m using POST, other forms return error.
2. When I run this application locally (with Xampp – Apache 2.2) everything works fine without any error, but whenever I run the application an the remote server (IIS 7), I get these errors and problems.

Answer 1

Finally I changed the server that my files were located on it. I tried them on another server (same OS), and everything worked fine.
I could not get what was the reason… This was the first time that I was getting this unknown error.
However, thank you all for your suggestions and comments.
