Users disabling certain extensions for themselves?

onetwentyeight · July 2006

I was wondering if it was possible to allow users the ability to turn on and off certain extensions on their own, or if each extensions needed to be coded to create a user preference. For example, some of my members really enjoy the yellow fade and the quick tags, but others dont like them at all, and I'd like to give people an option. At the moment I only see how I can enable and disable them globally. Is there something I'm missing?

It's all up to the extension programmer. Some extensions should work globally, some can be switched on or off in the Forum Prefereces.

But it's really easy to change an extension and have it switched on/off by a user! Let's take a look at the YellowFade add-on:


<?php
/*
Extension Name: YellowFade Effect
Extension Url: http://michaelraichelson.com/hacks/vanilla/
Description: Adds the YellowFade effect on some stuff.
Version: 0.1
Author: Michael Raichelson
Author Url: http://michaelraichelson.com/
*/

if (in_array($Context->SelfUrl, array("index.php", "categories.php", ... bla bla.. {
    $Head->AddScript('extensions/YellowFade/functions.js');
}
?>

Now let's make a user preference, so we add the following:


if ($Context->SelfUrl == 'account.php') {
	$Context->AddToDelegate('PreferencesForm', 'PreRender', 'YellowFade_PreferencesForm');
	function YellowFade_PreferencesForm(&$PreferencesForm) {
		$PreferencesForm->AddPreference('Other', 'EnableYellowFade', 'showYellowFade');
	}
}

The second parameter for adding a preference is our language definition, so we should add it to our dictionary:


$Context->Dictionary['EnableYellowFade'] = 'Show YellowFade';

And now we need to check for the preference if we need to add the javascript to the head object:


	if( $Context->Session->User->Preference('showYellowFade')) {
		$Head->AddScript('extensions/YellowFade/functions.js');
	}

We're done!

@Jazzy (May I call you that?) ; )

If you got a min, I got this working and the pref is there, but toggling the button makes no difference. YellowFade is on regardless. Hmmm?

Jazzman · July 2006

Yeah, you can call me Jazzy

Here's the full code (maybe you made a typo? It works for me):


<?php
/*
Extension Name: YellowFade Effect
Extension Url: http://michaelraichelson.com/hacks/vanilla/
Description: Adds the YellowFade effect on some stuff.
Version: 0.1
Author: Michael Raichelson

*/

$Context->Dictionary['EnableYellowFade'] = 'Show YellowFade';

if (in_array($Context->SelfUrl, 
	array("index.php", "categories.php", "comments.php", "search.php", 
		  "post.php", "account.php", "settings.php"))) {
	if( $Context->Session->User->Preference('showYellowFade')) {
		$Head->AddScript('extensions/YellowFade/functions.js');
	}
}

// Add preference
if ($Context->SelfUrl == 'account.php') {
	$Context->AddToDelegate('PreferencesForm', 'PreRender', 'YellowFade_PreferencesForm');
	function YellowFade_PreferencesForm(&$PreferencesForm) {
		$PreferencesForm->AddPreference('Other', 'EnableYellowFade', 'showYellowFade');
	}
}
?>

phaded · July 2006

Not to bump a thread, but I used the code that jazzman posted, and although there's an option to turn yellowfades off, it doesn't do anything if someone wants to do that.

3stripe · July 2006

Hmm I'm having problems with this also... maybe http://lussumo.com/docs/doku.php?id=vanilla:development:userpreferences&s=user+preferences has some answers...

Jazzman, can you use your binary powers to fix this... somethings is very wrong cos it does nothing:

<?php
