Nette, Dibi a našeptávání

neco podobneho jsem resil (tagum jsem ale rikal „keywords“), a jeste s tou funkci, ze kdyz tag neexistoval, tak se automaticky pridal.

prirazeni tagu pak spocitalo v tom, ze se tag pridal do multi-selectboxu, takze jsem pak jeste musel pridat udalost na odesilani formulare, aby se v selectu oznacilo vse (samozrejme sem to mohl cpat do nejakeho hidden inputu)…

data z naseptavace lezli pres ajax pres handler.

	/**
	 * @param string $kw
	 * @return void

		$this->payload->kwAutoComplete = array();

		$kw = \Nette\String::trim($kw);
		if (!empty ($kw) && (strlen($kw) >= 3)) {
			$keywords = Keyword::find($kw);
			if (!empty ($keywords)) {
				foreach ($keywords as $keyword) {
					$this->payload->kwAutoComplete[$keyword->getId()] = $keyword->getWord();
				}
			}
		}
		$this->terminate();
	}
