Problém pri presune z local(u) na hosting

StanlieK

Ahojte, pri presune na hosting, z local(u) mi Nette hádže túto chybu… Na locale ju nehádže, ako z toho von.

Chyba: Using $this when not in object context

25:        }
26:
27:        protected function createComponentForm($name) {
28:            $form = new Nette\Application\UI\Form($this, $name);
29:
30:            $znackyPairs = $this->znackyRepository->findAll()->order('znacka ASC')->fetchPairs('id', 'znacka');
31:
32:            $form->addSelect('znacka', 'Značka', $znacka = array('0' => 'Nezáleží', $znackyPairs));
33:            $form->addDSelect('model', 'Model', $form['znacka'], function($form) {
34:                $v = $form['znacka']->getValue();
35:                $modelsPairs = $this->modelyRepository->findBy(array('znacka_id' => $v))->order('model ASC')->fetchPairs('id', 'model');
36:                if ($v == '0'){
37:                    $modelyPairs = $this->modelyRepository->findAll()->order('model ASC')->fetchPairs('id', 'model');
38:                    return array ('0' => 'Nezáleží', $modelyPairs);
39:                }

Chyba je na 35: riadku.

Pridávam aj celý zdroj:

}

Ako z toho von, prosím.

Aku verziu PHP mas na serveri?

Edit:
Ak tam mas PHP 5.3 a nie PHP 5.4, nemozes pouzit $this v anonymnych funkciach. T.j. musis spravit nieco taketo:

$self = $this;

$form->addDSelect('model', 'Model', $form['znacka'], function($form) use ($self) {
	$v = $form['znacka']->getValue();
	$modelsPairs = $self->modelyRepository->findBy(array('znacka_id' => $v))->order('model ASC')->fetchPairs('id', 'model');
	if ($v == '0'){
        	$modelyPairs = $self->modelyRepository->findAll()->order('model ASC')->fetchPairs('id', 'model');
		return array ('0' => 'Nezáleží', $modelyPairs);
	} else {
		return array('0' => 'Nezáleží', $modelsPairs);
	}
});

A je tu ďalší problém. Vie to niekto prepísať tak, aby to fungovalo na PHP 5.3? Prosím, ja to asi fakt nezvládnem sám, potrebujem pomoc.

Tento script teraz hádže túto chybu – Cannot read an undeclared property HomepagePresenter::$modelyRepository.

A este dalsia vec: skus si pozriet injectovanie sluzieb do presenteru – https://pla.nette.org/…ect-autowire. Zbavis sa tym toho nepekneho $this->context->znackyRepository a pod. v startupe.

StanlieK

Vedel by mi niekto ukázať to injectovanie napr. na tomto scripte. Pretože ten návod nejako neviem pochopiť, neviem, čo mi je :D, ale fakt mi to nechce do hlavy ísť, aj keď možno len niekde robím chybu … Vďaka za pochopenie

p.s. Ďakujem peter.z, script mi už pekne krásne funguje.

llook

public function __construct(Nette\DI\Container $context, ZnackyRepository $znacky, ModelyRepository $modely) {
	parent::__construct($context);
	$this->znackyRepository = $znacky;
	$this->modelyRepository = $modely;
}

peter.z

Cez inject:

public function injectRepositories(ZnackyRepository $znackyRepository, ModelyRepository $modelyRepository)
{
	$this->znackyRepository = $znackyRepository;
	$this->modelyRepository = $modelyRepository;
}

Funkcia ale predpoklada, ze ZnackyRepository a ModelyRepository su v rovnakom namespace ako presenter, tak si to budes musiet pravdepodobne upravit podla seba.

StanlieK

Vďaka vám obom :-). Ja sa s tým už nejako vysporiadam :-).
