Add / remove link in Useful Links block

In order to create own link - add this code to site.php file:

Am_Di::getInstance()->hook->add(Am_Event::GET_MEMBER_LINKS, function (Am_Event $e){
    //simple way to add link with url and label
    $e->addReturn('LINK TITLE', '/url/');
    $e->addReturn('LINK TITLE 2', '/url2/');
    
    //also you can pass any desired attributes to <a> tag:
    $e->addReturn([
        'label' => 'LINK TITLE 3',
        'href' => '/url3/',
        'target' => '_blank',
        'class' => 'my-link',
        'style' => 'color:red; font-weight:bold',
    ]);
});

In order to remove link use this code (example is to remove Payment History link):

Am_Di::getInstance()->hook->add(Am_Event::GET_MEMBER_LINKS, function(Am_Event $e){
    $ret = $e->getReturn();
    foreach($ret as $k=>$v) {
        if(strpos($k, 'payment-history')!==false) {
            unset($ret[$k]);
        }
    }
    $e->setReturn($ret);
});
