echo $text;

?>

<form action="<?php $PHP_SELF; ?>" method="post">
texT:
<input type="text" name="text" />
</form>
[/code]

I get the error:
Fatal error: Call to undefined function: input()

I want to be able to use that clsas core file and have $Omega->Function functions....

any ideas? i know it can be done i just forget how :P

The code you have posted should work. The error you post howver refers to a function called input() NOT Input(). Are you sure this is the relevent coe?

ps: Whatever editor your using to copy / paste this code... get rid of it. Your formatting is near impossible to read.

[localhost]

that is the exact code and i still get the error for input().

You dont close the constructor (Omega function) in your class:
[code]function Omega()
{

} // <-- missing closing brace.[/code]

Is nesting of function definitions now permitted? I thought it was a no-no in PHP.

Or am I reading that mess of code incorrectly?

You've always been able to nest functions in PHP AFAIK. To call nested function you first have to call the function that is containing the nested functiont first, then you can call the nested function. Example:
[code=php:0]function foo()
{
    echo 'foo<br />';

    function bar()
    {
        echo 'bar';
    }
}

// call parent function
foo();

// now call nested function
bar();[/code]

I'm sure I tried to do something like this a long time ago and it failed.
[code]<?php
function foo()
{
    function bar()
    {
        echo 'bar';
    }
    echo 'foo<br />';

    bar();
}

foo();
?>[/code]

Guess I had something else wrong and made wrong assumption.

Thanks for that Wildteen
