如何将$$变量传递给CakePHP中的控制器进行查看？

in AppController:

function beforeFilter() {

    $company = 'name of Company';

    $this->set(compact('company'));

}

in Controller class:

function companyinfo() {
    $logo = '<div><?php $this->Html->image('logo'); ?></div>';
    $welcome = 'welcome to $$company!';

    $this->set(compact('logo','welcome'));
}

function beforeFilter() {
    parent::beforeFilter();
}

in View class:

<html>
    <body>
        <?php echo $logo; ?>
        <?php echo $welcome; ?>
    </body>
</html>

it doesn't answer variable in view after passing the variable from AppController via controller..

    1) When you use $this->set(compact('company'));, it is NOT setting a variable for use in any controller - it's passing $company to the view.

    2) You're trying to write PHP code in a string, using a Helper (which are only available in Views)

    $logo = '<div><?php $this->Html->image('logo'); ?></div>';

    3) It's unusual to want to pass data from AppController to Controller to View.

    What you probably want to do is something like this:

    //App Controller 
function beforeFilter() {
    $company = 'name of Company';
    $this->set(compact('company'));
}

//Controller
function companyinfo() {
    $logo = 'logo';
    $this->set(compact('logo'));
}

//Layout file (or view file, but I assume it's layout since you're getting data in the AppController)
<?php
echo '<div>' . $this->Html->image($logo) . '</div>';
echo "Welcome to " . $company;

    I mean this in the most constructive way possible (we've all been there). It seems like you're struggling with some general PHP concepts. Before you get too heavy into CakePHP, I recommend trying out a few lengthy tutorials in generic PHP - then when you feel completely comfortable with it, dive into CakePHP.
