how to submit a form from frontend and show values in the grid at backend magento panel? - zend-framework

Question

i am again posting this question as i was unable to do what i wanted to, and also didn't get the answer of my previous question. Hope, this time it will catch the eye of someone who can answer.
I have created a module which enables to submit a form in the backend just like news module and faqs module etc and shows the result in the grid.
But what i want now is that i must be able to save the form frontend and show the results in grid.
i was told that it can be done through indexcontroller.php of my module. So what i actually did was i copied the save action of adminhtml controller and try to use it in index controller.
public function postAction() {
if ($data = $this->getRequest()->getPost()) {
$model = Mage::getModel('events/events');
$model->setData($data)
->setId($this->getRequest()->getParam('id'));
try {
if ($model->getCreatedTime == NULL || $model->getUpdateTime() == NULL) {
$model->setCreatedTime(now())
->setUpdateTime(now());
} else {
$model->setUpdateTime(now());
}
$model->save();
Mage::getSingleton('core/session')->addSuccess(Mage::helper('events')->__('Item was successfully saved'));
Mage::getSingleton('core/session')->setFormData(false);
if ($this->getRequest()->getParam('back')) {
$this->_redirect('*/*/edit', array('id' => $model->getId()));
return;
}
$this->_redirect('*/*/');
return;
} catch (Exception $e) {
Mage::getSingleton('core/session')->addError($e->getMessage());
Mage::getSingleton('core/session')->setFormData($data);
$this->_redirect('*/*/edit', array('id' => $this->getRequest()->getParam('id')));
return;
}
}
Mage::getSingleton('core/session')->addError(Mage::helper('events')->__('Unable to find item to save'));
$this->_redirect('*/*/');
}
/* testing */
and in frontend i created a phtml file :
<div id="messages_product_view"><?php echo $this->getMessagesBlock()->getGroupedHtml() ?></div>
<form action="<?php echo $this->getPostActionUrl(); ?>" method="post" enctype="multipart/form-data" id="events_form">
<div class="fieldset">
<ul class="form-list">
<li>
<label for="title"><em>*</em><?php echo Mage::helper('events')->__('Title:') ?></label>
<div class="input-box">
<input style="font-size:14px;" name="title" id="content" value="" class="input-text required-entry" type="text" size="29"/>
</div>
</li>
<li class="wide">
<label for="content" class="required"><em>*</em><?php echo Mage::helper('events')->__('Description:') ?></label>
<div class="input-box">
<textarea name="content" id="content" title="<?php echo Mage::helper('events')->__('Description') ?>" class="input-text required-entry" style="font-size:14px;" name="overview" cols="55" rows="30"></textarea>
</div>
</li>
</ul>
</div>
<div class="buttons-set">
<p class="required"><?php echo Mage::helper('events')->__('* Required Fields') ?></p>
<input type="text" name="hideit" id="hideit" value="" style="display:none !important;" />
<button type="submit" title="<?php echo Mage::helper('events')->__('Submit') ?>" class="button"><span><span><?php echo Mage::helper('events')->__('Submit') ?></span></span></button>
</div>
</form>
<script type="text/javascript">
//<![CDATA[
var eventsForm = new VarienForm('events_form', true);
//]]>
</script>
But no luck :( can anyone please tell me how to get it done.
