how to share the variable to different function on the same class

  • I want to print what I input in wordpress, but I still not get the variable from different function in the same class
    The following is my code:

    class Test{
    private $infos;
      
    function get_info() {
        if ( isset($_REQUEST['my_info']) ) {
            $this->infos = $_REQUEST['my_info'];
            echo 'your input is:'.$this->infos;
        }
        
        // Always die in functions echoing ajax content or it will display 0 or another word
    //    die();
    }
    
    function salcodes_year() {
        echo 'the data is:'.$this->var;
        return $this->var;        
    }

    function js2php_register(){
        add_action( 'wp_ajax_test_info', array($this, 'get_info') );
        add_action( 'wp_ajax_nopriv_test_info', array($this, 'get_info') );
        add_shortcode( 'current_year', array($this, 'salcodes_year') );
    }
    
}

$test = new Test;
$test->js2php_register();

    Version:
    WordPress 5.8.2
    PHP 7.4.27
    MySQL 5.7.37 Community Server (GPL)

    Help me, please!

    $var is never assigned anywhere. You assign $infos with an Ajax request, that’s fine, but you’re not using $infos anywhere else. Once assigned, class properties are available in other class methods. For example, add this to your class:

    private $var2;
function __construct() {
   $this->var2 = 'foo';
}
function get_var2() {
    return $this->var2;
}

    then after instantiating your class object, you could do
    echo 'Value of var2: ',$test->get_var2();

    We’re happy to help you here, but FWIW, you might get a better response to general PHP questions that are not really related to WP in a forum dedicated to helping people needing general PHP help. stackexchange.com or stackoverflow.com maybe?
