Nella forms, datetime vrací NULL

SvvimX

Ahoj,

chtěl jsem využít Nella forms, které krásně implementují metody jako addDateTime, dokonce snad cosi s Tagy, ale jednoduchý form:

class BaseForm extends \Nella\Forms\Form {
	$this ->addDateTime( 'start', 'Start date' )
                ->setAttribute( 'class', 'inputbox');
                ;
}

mi vrací neustále NULL

start => NULL

Také by se mi hodil nějaký menší návod, jak pracovat s políčkem pro tagy a co to umí.

Ukaž celou třídu, ne tenhle nefunkční kousek.

Ok, ale na tom asi není nic zvláštního, mám takle x formulářů a všechna data se mi odešlou, jen addDateTime z Nelly nějak nechce, přitom se tak hezky vykreslí..

<?php

namespace CCM\Form;

class BaseForm extends \Nella\Forms\Form {

    public function __construct( \Nette\ComponentModel\IContainer $parent = NULL, $name = NULL ) {

        parent::__construct( $parent, $name );

         $this -> setTranslator ( \Nette\Environment::getService("translator") );

    }

}

class ProjectForm extends BaseForm {


    public function __construct( array $workers, array $companies, \Nette\ComponentModel\IContainer $parent = NULL, $name = NULL ) {

        parent::__construct( $parent, $name );

        $this -> setMethod ( "POST" );

        $this -> addText( 'title', 'Title' )
                -> setRequired ( 'Please enter %label' )
                ->setAttribute( 'class', 'inputbox');
                ;

	$this -> addTextArea( 'description', 'Description' )

                ->setAttribute( 'class', 'inputbox');

                ->setAttribute( 'class', 'inputbox');
                ;

	$this ->addNumber( 'price', 'Price', 100, 0 )
                ->setAttribute( 'class', 'inputbox');

Přišel jsem na důvod, není to v mé třídě, je to tím, že Nella forms využívají html5 input type=„datetime“ který vrací datum ve formátu date velké písmeno „T“ time a „Z“ tedy např: 1990–12–31T23:59:60Z

a v nella forms baseDateTime je

public function getValue()
	{
		$value = parent::getValue();
		$value = DateTime::createFromFormat(static::$format, $value);
		$err = DateTime::getLastErrors();
		if ($err['error_count']) {
			$value = FALSE;
		}
		return $value ?: NULL;
	}

následující datum naplní proměnnou $err

"2013-05-29T12:00Z" (17)
array(4) {
   warning_count => 0
   warnings => array(0)
   error_count => 2
   errors => array(2) {
      10 => "Unexpected data found." (22)
      16 => "Trailing data" (13)
   }
}

Chápu to tedy jako bug v Nella Forms?

imho v tom případě máš špatně nastavený $format

SvvimX

Nechal jsem tam default, v domění že vše samo poběží :-)

Navíc dateTime nemá funkci setFormat, očekává se tedy, že si přepíši formát přímo ve skriptu?

/** @var string */
public static $format = 'Y-n-j H:i';

Nebo ve formuláři jaksi:

$this ->addDateTime( 'end', 'End date' )
       ->setAttribute( 'class', 'inputbox input-xxlarge');
       -> format = "Y-n-jTH:iZ"; // navíc, kdo ví, jak ten formát má vypadat...?

Neprepisoval by som cudzí kód. Vytvor si vlastnú komponentu, ktorá bude dediť z Nella\Forms\Controls\Date a tam prepíš $format.

namespace CCM\Controls;

class Date extends \Nella\Forms\Controls\Date {

	/** @var string */
	public static $format = 'd.m.Y';
}

Túto komponentu použi v tvojom formulári:

namespace CCM\Form;

use CCM\Controls\Date;

class BaseForm extends \Nella\Forms\Form {

    public function __construct( \Nette\ComponentModel\IContainer $parent = NULL, $name = NULL ) {

	parent::__construct( $parent, $name );

	$this -> setTranslator ( \Nette\Environment::getService("translator") );

    }

	public function addDate($name, $label = NULL, $cols = NULL) {
		return $this[$name] = new Date($label, $cols, NULL);
	}

}

To isté pre DateTime…
