Store value to variable Opencart - php

Question

I think this is basic problem for open cart, but I cant fix it, in view I put 1 field head_text_field then i put to variable in controller then use var_dump for check value
This for View :
<?php echo $header; ?>
<div id="content">
<div class="breadcrumb">
<?php foreach ($breadcrumbs as $breadcrumb) { ?>
<?php echo $breadcrumb['separator']; ?><?php echo $breadcrumb['text']; ?>
<?php } ?>
</div>
<?php if ($error_warning) { ?>
<div class="warning"><?php echo $error_warning; ?></div>
<?php } ?>
<?php if ($success) { ?>
<div class="success"><?php echo $success; ?></div>
<?php } ?>
<div class="box">
<div class="heading">
<h1><img src="view/image/product.png" alt="" /> <?php echo $heading_title; ?></h1>
<div class="buttons"><a onclick="$('#form').submit();" class="button"><?php echo $button_save; ?></a><?php echo $button_cancel; ?></div>
</div>
<div class="content">
<form action="<?php echo $action; ?>" method="post" enctype="multipart/form-data" id="form">
<table class="form">
<tr>
<td><span class="required">*</span> <?php echo $entry_head; ?></td>
<td><input type="text" name="head_text_field" value="<?php echo $head_text_field; ?>" placeholder="Input Head Text" size="40"/></td>
</tr>
</table>
</form>
</div>
</div>
</div>
<?php echo $footer; ?>
Controller:
<?php
class ControllerItemItem extends Controller {
private $error = array();
public function index() {
$this->language->load('item/item');
$this->document->setTitle($this->language->get('heading_title'));
$this->getList();
}
protected function getList(){
if (isset($this->request->get['head_text_field'])){
$head_text_field = $this->request->get['head_text_field'];
var_dump($head_text_field); exit; // VAR_DUMP HERE
} else {
$head_text_field = null;
echo "FAILED"; // FAILED HERE
}
$this->data['breadcrumbs'] = array();
$this->data['breadcrumbs'][] = array(
'text' => $this->language->get('text_home'),
'href' => $this->url->link('common/home', 'token=' . $this->session->data['token'], 'SSL'),
'separator' => false
);
$this->data['breadcrumbs'][] = array(
'text' => $this->language->get('heading_title'),
'href' => $this->url->link('module/item', 'token=' . $this->session->data['token'], 'SSL'),
'separator' => ' :: '
);
$this->data['heading_title'] = $this->language->get('heading_title');
$this->data['entry_head'] = $this->language->get('entry_head');
$this->data['button_save'] = $this->language->get('button_save');
$this->data['button_cancel'] = $this->language->get('button_cancel');
$this->data['cancel'] = $this->url->link('extension/module', 'token=' . $this->session->data['token'], 'SSL');
$this->data['action'] = $this->url->link('item/item/insert', 'token=' . $this->session->data['token'], 'SSL');
$this->data['token'] = $this->session->data['token'];
$this->template = 'item/item.tpl';
$this->children = array(
'common/header',
'common/footer'
);
$this->response->setOutput($this->render());
}
public function insert()
{
var_dump($head_text_field); exit;
}
}
?>
When I try input, result is FAILED?? Where I did mistake? for model I not call or use it right now in controller.
EDIT 1
Sorry i add function insert for make it not error (for button insert in controller bottom)

Answer 1

If you want to get any variable from opencart controller in your view then you need to pass this variable as below:
Controller File
if (isset($this->request->post['head_text_field'])){
$this->data['head_text_field'] = $this->request->get['head_text_field']; // Your variable
var_dump($this->data['head_text_field']); exit; // VAR_DUMP HERE
} else {
$this->data['head_text_field'] = null;
echo "FAILED"; // FAILED HERE
}
Now you can get head_text_field in your view file as $head_text_field.
Edit
public function insert()
{
if (($this->request->server['REQUEST_METHOD'] == 'POST')) {
echo $this->request->post['head_text_field']; // Your field value
}
}

Answer 2

$this->request->post['head_text_field']
