cakephp - How to define FlashHelper/Component element for general authError message -

after updating cakephp 2.6.2 2.7.2 missing key error when auth flash message created. how can define element template default autherror?

since sessioncomponent::setflash() has been deprecated added flashcomponent in app/controller/appcontroller.php , modified flash messages this:

// controller $this->session->setflash('done', 'succeed'); $this->session->setflash('there error', 'failure'); $this->session->setflash('please log in', 'auth'); // view (default layout) echo $this->session->flash(); echo $this->session->flash('auth'); 

to this:

// controller $this->flash->succeed('done'); $this->flash->failure('there error'); $this->flash->auth('please log in'); // view (default layout) echo $this->flash->render(); echo $this->session->flash();       // keep temporarily? echo $this->session->flash('auth'); // keep temporarily? 

i copied flash related templates app/view/elements/succeed.ctp app/view/elements/flash/succeed.ctp

this working – but if not logged in , try access admin page default autherror message defined in app/controller/appcontroller.php shown without according template. debug mode 2 following error:

// undefined variable: key [core\cake\view\elements\flash\default.ctp, line 1] // include - core\cake\view\elements\flash\default.ctp, line 1 // view::_evaluate() - core\cake\view\view.php, line 971 // view::_render() - core\cake\view\view.php, line 933 // view::_renderelement() - core\cake\view\view.php, line 1227 // view::element() - core\cake\view\view.php, line 418 // sessionhelper::flash() - core\cake\view\helper\sessionhelper.php, line 159 // include - app\view\layouts\default.ctp, line 142 // view::_evaluate() - core\cake\view\view.php, line 971 // view::_render() - core\cake\view\view.php, line 933 // view::renderlayout() - core\cake\view\view.php, line 546 // view::render() - core\cake\view\view.php, line 481 // controller::render() - core\cake\controller\controller.php, line 960 // dispatcher::_invoke() - core\cake\routing\dispatcher.php, line 200 // dispatcher::dispatch() - core\cake\routing\dispatcher.php, line 167 // [main] - app\webroot\index.php, line 118 // message" class="message"> 

what changes in appcontroller.php necessary default autherror rendered own element template "auth"?

here part of appcontroller.php:

public $components = array(   'flash',   'session',   'security',   'auth' => array(     'authenticate' => array('form' => array('passwordhasher' => 'blowfish')),     'autherror' => 'my default auth error message.', // how have modify line?     'loginaction' => array('controller' => 'users', 'action' => 'login'),     'loginredirect' => array('controller' => 'users', 'action' => 'welcome'),     'logoutredirect' => array('controller' => 'users', 'action' => 'goodbye'),   ) ); 

and these 2 lines still necessary when changing flash messages in controllers flash compoment , helper? else used cakephp?

echo $this->session->flash(); echo $this->session->flash('auth'); 

i had @ authentication tutorial. seems not date since $this->session->setflash() still heavily in use...

in auth component setting array add like

'auth' = [     ...     'flash' => ['element' => 'auth_error'],     ... ] 

then create template named auth_error.ctp in element/flash directory. in file variable use should $message, because when cake calls flash auth components not pass other variable (i.e. $key variable)

maybe answer not 100% correct (so suggestion welcome) worked me.
