best way to pass form values

Nette always has interesting ways to do things
that i dont know yet, so thought i would ask..

I know i can pass form values from step1presenter
to step2 presenter with:

A>

$this->getHttpRequest()->getPost();

code above in step 2 constructor…
or

B>

public function __construct(array $data) {
...

above code in step 2…

or

C>

/** @persistent */
public array $values;
$values = $form->values;

code above in step 1 and then capture with A> or B> above

or (i think…)
D>

{var $formvals = $form->values}
<div class="col-xs-12 col-md-4 pull-right" n:snippet="box1">
	<a class="ajax btn btn-success btn-sm" n:href="{link step2:, data => $formvals}">Next Step2</a>
</div>

But given I dont want to store the data in db or file until step 4 or 5…
I think Step A and C are simplest way. But Step D and B seem good too.
or maybe something even more optimal is available? I really want to standardize
how i pass data from presenter to presenter…

thanks for any input…
James

Can you describe what your form does?

In general you can use a single dynamic form with a mix of checkboxs or buttons that add or remove new fields or even form-multiplier for a collection of forms

thanks vm,
its too early in the dev cycle for nice forms like you mention.
but eventually…

step 1 form is simple and is working fine…


Class LessonOneFormFactory {
	public function create(): Form {
		$form = new Form();
		$form->setMethod('GET');
		$items = [
					'simple' => 'simple',
					'moderate' => 'moderate','advanced' => 'advanced','smart' => 'smart'
		];
		$form->addRadioList('type','Structure',$items)
			->setHtmlAttribute('data-nette-compact');
		$form->addCheckbox('userpref');
		$form->addCheckbox('updatepref');
		$form->addHidden('manager');
		$form->addHidden('location');
		$form->addHidden('docguid');
		$form->addSubmit('send');
		$form->addSubmit('clear');

		return $form;
	}

i am only working on path 1 (simple option) then step two in this path will
query user for presentation method (upload or create simple html), then …
put into a distribution queue, then deliver via X.

moderate/advanced/smart paths 2–4 will require more…

as you can see in the form, i plan to let them store their selections
in their preferences too…
Thanks
James

In my opinion your multi-step form could be done with just one form, but look at this:

Hey Dsar,
yes, thats very nice. agreed. will give it a try after i
understand the less elegant way…

I also like this piece:

/** @var Wizard @inject */
	public $wizard;

as it will help me simplify my constructors a lot…

thanks again, you confirmed what i thought, that
there is another nice way…i didnt see that package in
componnette…
regards,
James

i cannot seem to pass a simple query to a presenter constructor
i setup TestingPresenter as follows

use Nette;
class TestingPresenter extends Nette\Application\UI\Presenter {
	public $data;
	public function __constructor(string $data="") {
		$this->data = $data;
	}
	public function renderDefault () {
		$this->template->data = $this->data;
	}
}

i set up the default.latte for Testing:

{block content}
<H3>{$user->getIdentity()->name}</H3>
<h4>{$data}</h4>
{/block}

the latte prints only my name, and not the $data string.

I tried these links in another Presenter with out success

$nexturl = $this->link('Testing:', ['data' => 'test']);
$this->template->nexturl = $nexturl;

and

<div >click <a href="{$nexturl}">Here</a></div>

and

<a class="test" href="{link {$next}: data => 'test' }">

with the code being:

protected string $next = "Testing";

i can see this → mydomain/testing/?data=test in the browser but
the word “test” is not being displayed in the Testing template.

I am sorry to ask for help on something seems so simple,
but have tried many diff ways…no success

well, solved it. went jogging
came back, decided the post data was prob
going to renderDefault(), not __constructor(),

so did this:

	public function renderDefault (string $data="") {
		$this->template->data = $data;
	}

and all is working fine. erased constructor. now i can
move on to walking the dog :-)

thanks much always, nette is awesome. a little
like climbing K2, at first :-)

You can't pass post variables to presenter constructor, it's wrong on many different levels…

Looks to me like you're missing some basic DI knowledge, see here: https://doc.nette.org/…introduction

thanks very much, yes i am still unlearning my old skills where i would instantiate objects inside classes
and pass all sorts of vars to the constructor…

i did find it passes arrays to renderDefault() …

i will learn… just have to practice, read,code,rinse and repeat.

regards,
James
