Hello experts,
How to get value from hidden element using Phalcon Forms and Volt?
SalesForm.php
class SalesForm extends Form
{
public function initialize($entity=null, $options=null)
{
$this->add(new Hidden('productIdList', array('value'=>'12345')));
}
}sales.volt
// I tried this method, but it show no value
{{ form.getValue("productIdList") }}I've read the API doc. But still no luck finding appropriate property or method.
Thank you.
Jim
Why not just use render() ?
{{ form.render('productIdList') }}I can't. Because sometimes I need to parse the value inside 'productIdList'. I don't need <input type="hidden" name="productIdList" id="productIdList" value="123|456" />, I just need the value, which mean '123|456'.
Hmm, if you just want to print variable, I think the simple $this->view->setVar('produdctIdList', ...) and {{ productIdList }} just more prefererable than just using Form. Anyway, all element in form will only have value after you set the entity object inside the Form object.
<?php
use Phalcon\Forms\Form;
use Phalcon\Forms\Element\Hidden;
class SalesForm extends Form
{
public function initialize($entity=null, $options=null)
{
$this->add(new Hidden('productIdList'));
}
}
$form = new SalesForm((object)['productIdList' => 20]);
echo $form->getValue('productIdList'); /// should print 20Thanks. I've followed your solutions.
