Call to a member function AddCssFile() on null

terabytefrelance

Because I can not add the css style sheet:

class Widgets_Plugin extends Gdn_Plugin{

    public function assetModel_styleCss_handler ($sender) {
        $Sender->AddCssFile('widgets.css', 'plugins/Widgets');
    }


Fatal Error in Widgets_Plugin.assetModel_styleCss_handler();

Call to a member function AddCssFile() on null

missing closing } maybe ? check syntax coz that is what it looks like .

I would use this to load css files

public function base_render_before ($sender) {
 $Sender->AddCssFile('widgets.css', 'plugins/Widgets');
    }

public function base_render_before ($sender) {
    $Sender->AddCssFile('widgets.css', 'plugins/Widgets');

    $controllers = [
        // ControllerName => Modules for Name Controllers.
        'categoriescontroller'  => ['Twitter','Exchange'],
        'discussioncontroller'  => ['Twitter'],
        'discussionscontroller' => ['Dolartoday', 'Twitter']
    ];

    if (!array_key_exists($sender->ControllerName, $controllers)) {
        return;
    }

    $modules = [
        // Widgest => Class Module Name
        'Twitter'  => 'TwitterModule',
        'Exchange' => 'ExchangeModule',
        'Dolartoday' => 'DolartodayModule'
    ];

    $session = Gdn::session();

    foreach ($controllers[$sender->ControllerName] as $item) {
        //var_dump($item);
        // do the permission check with "Plugins.Whatever.{$moduleName}.View"
        // attach module with $module = new $modules[$moduleName]();
        if ($session->CheckPermission('Plugins.Widgets.{$item}.View')) {
            $module = new $modules[$item]();
            $sender->addModule($module);
        }
    }
}

jajajaja, that idiot apologize the post wrote sender with the first letter in capital letters,

Thks,

That would not cause an issue as far as I know....

$Sender is the same thing as $sender . It's a mater of style not function. Vanilla code now requires or at least suggests that it should be $sender . But it should not affect the php function as far as the meaning ...

It actually does, since variables in PHP are case sensitive (only methods are case insensitive):

This line defined an argument $sender

@terabytefrelance said:
public function assetModel_styleCss_handler ($sender) {

And this line references a variable $Sender which !== $sender.

        $Sender->AddCssFile('widgets.css', 'plugins/Widgets');

As long as you stay consistent you can use either $Sender or $sender as you said, but if you mix them bad things happen (as terabytefrelance figured out).
