Magento 1.9 sending custom form - form data not found in controller - forms

Question

I am having trouble with a simple form. I am quite sure that I miss some critical info about this topic...
I created a custom module, I created a custom form
<?php
class modulename_History_Block_Adminhtml_History_Edit_Form extends Mage_Adminhtml_Block_Widget_Form {
protected function _prepareForm()
{
$form = new Varien_Data_Form(array(
'id' => 'edit_form',
'name' => 'edit_form',
'action' => $this->getUrl('*/*/history', array('id' => 'orders_export')),
'method' => 'post',
'enctype' => 'multipart/form-data',
'data' =>'somethingsomethingdarkaside'
));
$this->setForm($form);
$fieldset = $form->addFieldset('Filtrování objednávek', array('legend'=> 'Nastavte filtr pro report objednávek'));
$dateTimeFormatIso = Mage::app()->getLocale()->getDateTimeFormat(Mage_Core_Model_Locale::FORMAT_TYPE_SHORT);
$fieldset->addField('date_from', 'date', array(
'label' => 'Změna statusu objednávek od:',
'title' => 'Změna statusu objednávek od:',
'time' => true,
'name' => 'filter_date_from',
'image' => $this->getSkinUrl('images/grid-cal.gif'),
'format' => $dateTimeFormatIso,
'required' => true,
));
$fieldset->addField('export_history_order_status_changed', 'button', array(
'label' => 'Exportovat do souboru:',
'value' => 'Export',
'name' => 'export_history_order_status_changed',
'class' => 'form-button',
'onclick' => "setLocation('{$this->getUrl('*/*/export')}')",
));
$form->setUseContainer(true);
return parent::_prepareForm();
}
And then there is a controller. When the button is pressed, it goes to the correct controller to a correct action. However no data in post received:
<?php
class modulename_History_Adminhtml_History_HistoryController extends Mage_Adminhtml_Controller_Action {
protected function _initAction()
{
return $this;
}
/**
* A page with the form, creating the block with it.
*
*/
public function editAction()
{
$this->_title('Historie objednavky')
->loadLayout()
->_setActiveMenu('modulename/historymenu');
$this->_addContent($this->getLayout()->createBlock('modulename_history/adminhtml_history_edit'));
$this->renderLayout();
}
/**
* A main entrance - when the filter is set and the "export" button pressed then this is the function which starts.
*
* #return bool|Mage_Core_Controller_Varien_Action - either we return a downloadable file or we return false.
*/
public function exportAction()
{
if ($this->_setParameters())
{
if ($this->_setOrdersIds())
{
return $this->_getDownloadFile();
}
}
return false;
}
/**
* Try to get parameters from the admin form. If all correct then we return true. If there is something not set
* then we are unable to continue and we return false.
*
* #return bool - either we were successful with getting the parameters or not.
*/
protected function _setParameters()
{
$parameters = $this->getRequest()->getParams();
$pokus = $this->getRequest()->getPost();
$necf = $this->getRequest()->getPost('edit_form');
$neco = Mage::app()->getRequest()->getParam('edit_form');
}
}

Hellou,
so a competent colleque find an answer within minutes. I mean it was as silly as expected, just remove on click action on button and set the heading from the button to the form. And changed the button to submit. I quess the guy I copied the code from used some other spells of high magic so it worked for him. I hope this will help. Correct form below:
<?php
class modulename_History_Block_Adminhtml_History_Edit_Form extends
Mage_Adminhtml_Block_Widget_Form {
protected function _prepareForm()
{
$form = new Varien_Data_Form(array(
'id' => 'edit_form',
'name' => 'edit_form',
//'action' => $this->getUrl('*/*/history', array('id' => 'orders_export')),
'action' => $this->getUrl('*/*/export', array('id' => 'orders_export')),
'method' => 'post',
'enctype' => 'multipart/form-data',
'data' =>'somethingsomethingdarkaside'
));
$this->setForm($form);
$fieldset = $form->addFieldset('Filtrování objednávek', array('legend'=> 'Nastavte filtr pro report objednávek'));
$dateTimeFormatIso = Mage::app()->getLocale()->getDateTimeFormat(Mage_Core_Model_Locale::FORMAT_TYPE_SHORT);
$fieldset->addField('date_from', 'date', array(
'label' => 'Změna statusu objednávek od:',
'title' => 'Změna statusu objednávek od:',
'time' => true,
'name' => 'filter_date_from',
'image' => $this->getSkinUrl('images/grid-cal.gif'),
'format' => $dateTimeFormatIso,
'required' => true,
));
$fieldset->addField('export_history_order_status_changed', 'submit', array(
'label' => 'Exportovat do souboru:',
'value' => 'Export',
'name' => 'export_history_order_status_changed',
'class' => 'form-button',
//'onclick' => "setLocation('{$this->getUrl('*/*/export')}')",
));
$form->setUseContainer(true);
return parent::_prepareForm();
}
