best way to pass form values

jdan1131x

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…

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

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…

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

its a strange problem, maybe i am just tired.
i will use sessions to go around this.

jdan1131x

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

jdan1131x

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.
