Question

I searched, and found this question, which helped me:
php static variable is not getting set

It did, however, not solve my entire problem.

Code:

Class DummyClass {
    public static $result;

    function __construct() {
        $this->_setResultCode('testing');
    }

    public function getResultCode() {
        return self::$result['code'];
    }

    private function _setResultCode($val) {
        echo 'Im gonna set it to: ' . $val . '<br />';
        self::$result['code'] = $val;
        echo 'I just set it to: ' . $this->getResultCode;
        die();
    }
}

Outputs:

Im gonna set it to: testing
I just set it to:

What’s going on here? How is this even possible?

EDIT: The problem was i missed the parentheses when calling getResultCode(). HOWEVER, i have another issue now. I can’t seem to get the resultCode out of the class (later on in another instance of DummyClass).

Here is my relevant coded (No more example code because i seemed to mess that up):

Class lightweightContactFormPlugin {

// Set up/Init static $result variable
public static $result;

function __construct() {
    //echo 'I just inited<br/><pre>';
    //var_dump($this->getResultCode());
    //echo '</pre><br/>';
}

public function run() {

    // Set default value for resultCode
    $this->_setResultCode('no_identifier');

    // Check if form was posted
    if(isset($_POST['cfidentifier'])) {
        $fields = $this->_get_fields_to_send();
        $valid = $this->_validate_fields($fields);

        // Only continue if validatation was successful
        if($valid == true) {
            // Store mail result in $mail
            $mail = $this->_send_mail($fields);

            // Yay, success!
            if($mail) {
                $this->_setResultCode('sent_successfully');
                return;
            } else {
                // Couldn't send mail, bu-hu!
                $this->_setResultCode('not_sent');
                return;
            }
        }
        $this->_setResultCode('validation_fail');
        return;
    }
}


    // Get and Set methods
public function getResultCode() {
    return isset(self::$result['code']) ? self::$result['code'] : '';
}

private function _setResultCode($val) {
    self::$result['code'] = $val;
}
}

Left some irrelevant methods out. None of the other methods set or get the resultCode, it shouldn’t matter.

Any ideas why i can’t access $result[‘code’] in another instance of the object (further down the page)?

I do this when i access it:

    $plugin = new lightweightContactFormPlugin();
    $cfstat = $plugin->getResultCode();
    echo '<pre>';
    var_dump($fstat);
    echo '</pre>';

Result is:

NULL

The strange thing is, if i uncomment the code in __construct(), the CORRECT value does get printed out! But if i try to access it from getResultCode() after, it returns NULL again. What is going on?

Answer 1

echo 'I just set it to: ' . $this->getResultCode;

I think you’re missing a few parenthesis here.
