Jak vypsta filtrovaná data

nemáš na mysli něco podobného – dole jsem napsal můj nápad

` $id = (int)$data[‚uzivatel‘];` je vadné. Ta proměnná se ztratí- nemyslsel jsi $this->id?

Vážně nikdo nevíte jak nato?

Díky za radu. Asi to ale nechápu mam to teda takhle udělany. Ale když dám filtrovat tak mi to hodí error Call to undefined method HomepagePresenter::filtrSubmitted().

Jo to by měla to jsem přehlédl. Nic méně to teď celé projde ale do šablony se mi nic nevypíše.

Tak jsem to vyřešil takhle a chci se zeptat je to tak dobře? Nebo by jste to řešili úplně jinak?

Teď mi ale jde o tohle po odeslani formuláře adresa vypadá takhle

http://localhost/NetteFiltr/www/?do=form-submit

Já bych ale chtěl aby byla takováto.

http://localhost/NetteFiltr/www/

Půjde toho nějak docílit?

@Milhaus87 je to fajn (zobral si si moje doporucenia), ale uplne tip-top by bolo, keby si aj ten form nejako integroval do komponenty (normalne mozes dat tovarnicku do komponenty samotnej).

Co sa tyka tych URL, na to sa vykasli, userovi je uplne jedno co je v adresnom riadku pri odoslani formulara. Je to taka Nette konvencia, ze signaly maju takuto formu, obcas sa niekto najde, ze mu to vadi, ale fakt je zbytocne mrhat energiu na riesenie tejto malickosti.
