Упрощенная форма оформления заказа без регистрации

В сегодняшнем уроке я покажу, как сделать упрощенное оформление заказа в OpenCart БЕЗ регистрации.
Что имеется под "упрощенная форма"? Это не заказ в один клик, а оптимизация. 
Задача:
- убрать ненужные поля в форме (компания, факс, ид компании, адрес (продолжение), почтовый код);
- структурировать поля.

0. Делаем резервные копии файлов, которые будут редактированы в данном уроке:

\catalog\view\theme\default\template\checkout\guest.tpl

\catalog\view\theme\default\template\checkout\payment_address.tpl

\catalog\view\theme\default\template\checkout\guest_shipping.tpl

\catalog\controller\checkout\guest.php

\catalog\controller\checkout\payment_address.php

\catalog\controller\checkout\guest_shipping.php

\catalog\controller\checkout\confirm.php

\catalog\model\checkout\order.php

Версия OpenCart 1.5.4.1

1. Открываем файл: 

\catalog\view\theme\default\template\checkout\guest.tpl

удаляем:

<?php echo $entry_fax; ?><br />

<input type="text" name="fax" value="<?php echo $fax; ?>" class="large-field" />

<br />

<br />

<?php echo $entry_company; ?><br />

<input type="text" name="company" value="<?php echo $company; ?>" class="large-field" />

<br />

<br />

<div id="company-id-display"><span id="company-id-required" class="required">*</span> <?php echo $entry_company_id; ?><br />

<input type="text" name="company_id" value="<?php echo $company_id; ?>" class="large-field" />

<br />

<br />

<?php echo $entry_address_2; ?><br />

<input type="text" name="address_2" value="<?php echo $address_2; ?>" class="large-field" />

<br />

<br />

<span id="payment-postcode-required" class="required">*</span> <?php echo $entry_postcode; ?><br />

<input type="text" name="postcode" value="<?php echo $postcode; ?>" class="large-field" />

<br />

<br />

2. Ищем файл: 

\catalog\view\theme\default\template\checkout\payment_address.tpl

удаляем:

<tr>

<td><?php echo $entry_company; ?></td>

<td><input type="text" name="company" value="" class="large-field" /></td>

</tr>

<?php if ($company_id_display) { ?>

<tr>

<td><?php if ($company_id_required) { ?>

<span class="required">*</span>

<?php } ?>

<?php echo $entry_company_id; ?></td>

<td><input type="text" name="company_id" value="" class="large-field" /></td>

</tr>

<?php } ?>

<tr>

<td><?php echo $entry_address_2; ?></td>

<td><input type="text" name="address_2" value="" class="large-field" /></td>

</tr>

<tr>

<td><span id="payment-postcode-required" class="required">*</span> <?php echo $entry_postcode; ?></td>

<td><input type="text" name="postcode" value="" class="large-field" /></td>

</tr>

3. Убираем ненужно в: 

\catalog\view\theme\default\template\checkout\guest_shipping.tpl

<tr>

<td><?php echo $entry_company; ?></td>

<td><input type="text" name="company" value="<?php echo $company; ?>" class="large-field" /></td>

</tr>

<tr>

<td><?php echo $entry_address_2; ?></td>

<td><input type="text" name="address_2" value="<?php echo $address_2; ?>" class="large-field" /></td>

</tr>

<tr>

<td><span id="shipping-postcode-required" class="required">*</span> <?php echo $entry_postcode; ?></td>

<td><input type="text" name="postcode" value="<?php echo $postcode; ?>" class="large-field" /></td>

</tr>

4. Теперь работаем с файлами php. 

Открываем:

\catalog\controller\checkout\guest.php

$this->data['entry_address_2'] = $this->language->get('entry_address_2');

$this->data['entry_postcode'] = $this->language->get('entry_postcode');

$this->data['entry_company'] = $this->language->get('entry_company');

$this->data['entry_company_id'] = $this->language->get('entry_company_id');

$this->data['entry_fax'] = $this->language->get('entry_fax');

if (isset($this->session->data['guest']['fax'])) {

$this->data['fax'] = $this->session->data['guest']['fax'];

} else {

$this->data['fax'] = '';

}

if (isset($this->session->data['guest']['payment']['company'])) {

$this->data['company'] = $this->session->data['guest']['payment']['company'];

} else {

$this->data['company'] = '';

}

if ($country_info) {

if ($country_info['postcode_required'] && (utf8_strlen($this->request->post['postcode']) < 2) || (utf8_strlen($this->request->post['postcode']) > 10)) {

$json['error']['postcode'] = $this->language->get('error_postcode');

}

// VAT Validation

$this->load->helper('vat');

if ($this->config->get('config_vat') && $this->request->post['tax_id'] && (vat_validation($country_info['iso_code_2'], $this->request->post['tax_id']) == 'invalid')) {

$json['error']['tax_id'] = $this->language->get('error_vat');

}

}

// Company ID

if (isset($this->session->data['guest']['payment']['company_id'])) {

$this->data['company_id'] = $this->session->data['guest']['payment']['company_id'];

} else {

$this->data['company_id'] = '';

}

if (isset($this->session->data['guest']['payment']['address_2'])) {

$this->data['address_2'] = $this->session->data['guest']['payment']['address_2'];

} else {

$this->data['address_2'] = '';

}

if (isset($this->session->data['guest']['payment']['postcode'])) {

$this->data['postcode'] = $this->session->data['guest']['payment']['postcode'];

} elseif (isset($this->session->data['shipping_postcode'])) {

$this->data['postcode'] = $this->session->data['shipping_postcode'];

} else {

$this->data['postcode'] = '';

}

$this->session->data['guest']['fax'] = $this->request->post['fax'];

$this->session->data['guest']['payment']['company'] = $this->request->post['company'];

$this->session->data['guest']['payment']['company_id'] = $this->request->post['company_id'];

$this->session->data['guest']['payment']['address_2'] = $this->request->post['address_2'];

$this->session->data['guest']['payment']['postcode'] = $this->request->post['postcode'];

$this->session->data['guest']['shipping']['company'] = $this->request->post['company'];

$this->session->data['guest']['shipping']['address_2'] = $this->request->post['address_2'];

$this->session->data['guest']['shipping']['postcode'] = $this->request->post['postcode'];

$this->session->data['shipping_postcode'] = $this->request->post['postcode'];

5. \catalog\controller\checkout\payment_address.php

удаляем ненужное: 

$this->data['entry_company'] = $this->language->get('entry_company');

$this->data['entry_company_id'] = $this->language->get('entry_company_id');

$this->data['entry_address_2'] = $this->language->get('entry_address_2');

$this->data['entry_postcode'] = $this->language->get('entry_postcode');

6. \catalog\controller\checkout\guest_shipping.php

чистим мусор: 

$this->data['entry_company'] = $this->language->get('entry_company');

$this->data['entry_address_2'] = $this->language->get('entry_address_2');

$this->data['entry_postcode'] = $this->language->get('entry_postcode');

if (isset($this->session->data['guest']['shipping']['company'])) {

$this->data['company'] = $this->session->data['guest']['shipping']['company'];

} else {

$this->data['company'] = '';

}

if (isset($this->session->data['guest']['shipping']['address_2'])) {

$this->data['address_2'] = $this->session->data['guest']['shipping']['address_2'];

} else {

$this->data['address_2'] = '';

}

if (isset($this->session->data['guest']['shipping']['postcode'])) {

$this->data['postcode'] = $this->session->data['guest']['shipping']['postcode'];

} elseif (isset($this->session->data['shipping_postcode'])) {

$this->data['postcode'] = $this->session->data['shipping_postcode'];

} else {

$this->data['postcode'] = '';

}

if ($country_info && $country_info['postcode_required'] && (utf8_strlen($this->request->post['postcode']) < 2) || (utf8_strlen($this->request->post['postcode']) > 10)) {

$json['error']['postcode'] = $this->language->get('error_postcode');

}

$this->session->data['guest']['shipping']['address_2'] = $this->request->post['address_2'];

$this->session->data['guest']['shipping']['company'] = trim($this->request->post['company']);

$this->session->data['guest']['shipping']['postcode'] = $this->request->post['postcode'];

$this->session->data['shipping_postcode'] = $this->request->post['postcode'];

7. Избавляемся от ненужного в: 

\catalog\controller\checkout\confirm.php

$data['fax'] = $this->customer->getFax();

$data['fax'] = $this->session->data['guest']['fax'];

$data['payment_company'] = $payment_address['company'];

$data['payment_company_id'] = $payment_address['company_id'];

$data['payment_address_2'] = $payment_address['address_2'];

$data['payment_postcode'] = $payment_address['postcode'];

$data['shipping_company'] = $shipping_address['company'];

$data['shipping_address_2'] = $shipping_address['address_2'];

$data['shipping_postcode'] = $shipping_address['postcode'];

$data['shipping_company'] = '';

$data['shipping_address_2'] = '';

$data['shipping_postcode'] = '';

8. В этом файле будьте внимательны!!!

\catalog\model\checkout\order.php

на 4 строке (!!!) удалить: 

"', fax = '" . $this->db->escape($data['fax']) .

"', payment_company = '" . $this->db->escape($data['payment_company']) .

"', payment_company_id = '" . $this->db->escape($data['payment_company_id']) .

"', payment_address_2 = '" . $this->db->escape($data['payment_address_2']) .

"', payment_postcode = '" . $this->db->escape($data['payment_postcode']) .

"', shipping_company = '" . $this->db->escape($data['shipping_company']) .

"', shipping_address_2 = '" . $this->db->escape($data['shipping_address_2']) .

"', shipping_postcode = '" . $this->db->escape($data['shipping_postcode']) .

Обратите внимание на структуру кода! Масив начинается с "',  и заканчивается:  . ! Смотрите что удаляете. В противном случае получите ошибку sql. 

9. Вот и сказочки конец, а кто сделал - молодец :)
