Hi!

I'm getting insane with this.
I've the following:

login.php

class MyClass
{
    public $var = "I'm a class property!";
}

main.php

if (isset($_POST['submit'])) {
			include('login.php');
			$obj = new MyClass;  
			echo $obj->var();  
		}

My question is: Why this doesn't work? It doesn't appear anything on the screen.

then you have disabled error display. you try to call a method (which doesn’t exist and therefore produces an error) instead of a property.

Try echo $obj->var;

...?

Doesn't work either.

what do you mean? an explanation certainly does not make faulty code correct. it gives you an idea what went wrong and therefore where to fix things.

besides that: "It doesn’t work" is not good enough

Just to add a bit of an explanation to this.

PHP has a few configuration options that allow you to log and/or display error messages. During development you should always display all errors so that they won't go unnoticed and can be dealt with, whereas when your code is moved on to production servers you should turn the error display off and log them instead. You don't want normal users to have to see these errors.

To turn error reporting on on your development machine, set the display_errors directive to "On", and the error_reporting directive to "E_ALL".

If you can't change those in the PHP config file, you can turn them on for individual scripts by adding this to the very top:

ini_set("display_errors", true);
error_reporting(E_ALL);

Note, however, that errors that prevent the script from running at all, like syntax errors, will still not show if you do it like this. It's better to set them in the PHP config.

As I said:

I can't be more specific.

Doens't seem to work..because I do not get any kind of error, it doesn't display anything.

The problem is on this line:

if(isset($_POST['submit'])) {

}

Because, if I put only:

include('login.php');
$obj = new MyClass;  
echo $obj->prop1; 

It works.

Okey..solved.
Changed this:

<form action="login.php" method="post">

to this:

<form action="" method="post">

Thank you all.
