The extension is installed in LocalSettings.php as follows:

require_once($IP.'/extensions/InputBox/InputBox.php');

This is easy to fix, and you can simplify the code. Basically get rid of the Inputbox.hooks.php.
1. In Inputbox.php replace everything from line 50 on with:

// Register parser hook
if ( defined( 'MW_SUPPORTS_PARSERFIRSTCALLINIT' ) ) {
	// Modern
	$wgHooks['ParserFirstCallInit'][] = 'wfInputBox';
} else {
	// Legacy
	$wgExtensionFunctions[] = 'wfInputBox';
}

function wfInputBox ()
{
  new InputBox;
  return true;
}

2.In Inputbox.classes.php get rid of the __construct function and replace it with:
	function InputBox() {
	        global $wgParser;
		
		$wgParser->setHook( 'inputbox' , array( &$this, 'render' ) );
        }

	public function render( $input, $args, $parser ) {		
		$this->mParser = $parser;	       

		// Configure InputBox
		$this->extractOptions( $parser->replaceVariables( $input ) );

		// Return output
		return $this->render();
	}

and you're done!

sorry, there's a typo in the render() above, it should be:
	public function render( $input, $args, $parser ) {		
		$this->mParser = $parser;	       

		// Configure InputBox
		$this->extractOptions( $parser->replaceVariables( $input ) );


		// Internationalization

*** Bug 16246 has been marked as a duplicate of this bug. ***

This was probably due to changes in Hooks.php which I reverted in r43416.

No, it's still just as broken as ever. Same issue as before.

Works just fine here. PHP version?

Thanks for looking at this.  Here it's mediawiki 1.14alpha (r43263), php 5.2.0-8+etch13 (apache2handler), mysql 5.0.32-Debian_7etch8-log.

Here's a simpler view of it. It's the same as an issue that Rob Church documented for Extension:RandomImage.
The problem is a statement of the form:
	$wgparser->setHook( 'randomimage', 'RandomImage::renderHook' );
Yhe problem goes away if you do:
	$wgParser->setHook( 'randomimage', array('RandomImage', 'renderHook'));
Hope that helps.

Those are *function hooks* which are called directly with call_user_func_array() and must be a PHP callable.

Things in $wgHooks are *not* directly called; they are parsed and munged and, for backwards compatibility, we have retained that.

The relevant part of wfRunHooks() in Hooks.php is:

} elseif ( false !== ( $pos = strpos( $func, '::' ) ) ) {
	$callback = array( substr( $func, 0, $pos ), substr( $func, $pos + 2 ) );
} else {

This will translate the 'InputBoxHooks::register' into array('InputBoxHooks','register') which is the actual callable.

Can you confirm that you have a current version of both InputBox and MediaWiki trunk? Confirm that your Hooks.php is current, and does not have the broken version which broke these calls.

Can you then do some debugging to check the actual value of the callable at the time it's called in wfRunHooks()?

Ahhhh it's the render, not the register that you're seeing. Your sample code referring to the *register* function's registration -- which is entirely set up correctly -- threw me off.

Fixed in r43504.

yes, that fixes it. Thanks!
