How can I put a form in hookPaymentReturn?

[Oliver Mak]

Hi,

I am still new to module creation and I am now developing a payment module which I would need to put a form in Payment Return Hook so to collect some transaction data from the customers.

The ideal steps would be:

1. Customer choose to pay the order with my module
2. A QR code will be shown in Payment Return Hook for them to pay the order
3. After they pay it, they should input the reference number of the payment and it will be stored to Transaction ID

And actually I have created the form and display it well already, but I don't know how should I get the data back. Can anyone give me some idea please?

 

I have my hookPaymentReturn Code as below

public function hookPaymentReturn($params)
{
	/**
	 * Verify if this module is enabled
	 */
	if (!$this->active) {
		return;
	}

	$amount = substr($params['order']->total_paid,0,5);

	$result = Db::getInstance()->getRow('SELECT * FROM `' . _DB_PREFIX_ . 'hongkong_fps` WHERE id_hongkong_fps = 1');

	$fps_info = [
		'acc_type' => $result['account_type'],
		'bank_code' => $result['bank_code'],
		'acc_info' => $result['account_info'],
		'amount' => $amount
	];

	$qr = str_replace("+","%2B",getContentTxt($fps_info));

	$this->context->smarty->assign([
		'amount' => $amount,
		'qr' => $qr,
		'qr_link' => __PS_BASE_URI__ . 'modules/hongkong_fps/src/qrGen.php?code=' . $qr,
	]);

	$this->context->controller->addCSS( __PS_BASE_URI__.'modules/hongkong_fps/assets/css/payment_return.css'); 

	return $this->fetch('module:hongkong_fps/views/templates/hook/payment_return.tpl');
}

And my payment return tpl on below

<div class="d-flex justify-content-between">
	<div class="w-100 bootstrap">
		<p class="fps_msg">{l s='Please use the QR code on the right and pay by FPS' mod='hongkong_fps'}</p>
		<p class="fps_msg">{l s='Then provide the refernce number on below' mod='hongkong_fps'}</p>
		<p class="saved_ref d-none"><i class="material-icons done"></i>{l s='Ref. No.: ' mod='hongkong_fps'}</p>

		<form id="get_ref">
			<input type="text" name="ref_num" id="ref_num" placeholder="Reference Number">
			<button type="submit" name="submit_ref" id="submit_ref" class="btn btn-secondary mt-15">Submit</button>
		</form>
	</div>
	<div class="ml-25">
		<img src="{$qr_link}">
	</div>
</div>
