Need Help with Recurring Price Logic

Quote

Post by Majnoon » Thu Aug 17, 2023 6:07 pm

Hello fellas,

I am using opencart 3.0.3.8 with default theme.

I'm working on a modifying my opencart to deals with recurring pricing, and I've run into a roadblock that I hope someone here might be able to assist me with.
Recurring Prices: I have recurring products with various frequencies (e.g., day, week, month) and corresponding prices.
Displaying Options: I need to display these recurring options along with their prices as radio buttons on the product page.
Problem: The current code builds a recurring price string for each product, which is making it challenging to separate the prices for different recurring frequencies. I need to display individual prices , but the existing logic in controller doesn't align with this requirement.
Here's a snippet of the relevant code:
i did few changes to test so i am leaving them in code but as comment out.

Code: Select all

				$recurring = '';
				//$recurring_price = 0; // Initialize a variable to hold the recurring price

				if ($product['recurring']) {
					//$this->log->write('Recurring value: ' . print_r($product['recurring'], true));
					$frequencies = array(
						'day'        => $this->language->get('text_day'),
						'week'       => $this->language->get('text_week'),
						'semi_month' => $this->language->get('text_semi_month'),
						'month'      => $this->language->get('text_month'),
						'year'       => $this->language->get('text_year')
					);

					if ($product['recurring']['trial']) {
						$recurring = sprintf($this->language->get('text_trial_description'), $this->currency->format($this->tax->calculate($product['recurring']['trial_price'] * $product['quantity'], $product['tax_class_id'], $this->config->get('config_tax')), $this->session->data['currency']), $product['recurring']['trial_cycle'], $frequencies[$product['recurring']['trial_frequency']], $product['recurring']['trial_duration']) . ' ';
					}

					if ($product['recurring']['duration']) {
						$recurring_price = $this->currency->format($this->tax->calculate($product['recurring']['price'] * $product['quantity'], $product['tax_class_id'], $this->config->get('config_tax')), $this->session->data['currency']); // Extracting the recurring price
						//$recurring .= sprintf($this->language->get('text_payment_description'), $this->currency->format($this->tax->calculate($product['recurring']['price'] * $product['quantity'], $product['tax_class_id'], $this->config->get('config_tax')), $this->session->data['currency']), $product['recurring']['cycle'], $frequencies[$product['recurring']['frequency']], $product['recurring']['duration']);
					} else {
						$recurring .= sprintf($this->language->get('text_payment_cancel'), $this->currency->format($this->tax->calculate($product['recurring']['price'] * $product['quantity'], $product['tax_class_id'], $this->config->get('config_tax')), $this->session->data['currency']), $product['recurring']['cycle'], $frequencies[$product['recurring']['frequency']], $product['recurring']['duration']);
					}
				}

				//$data['recurring_price'] = $recurring_price;
				//$this->log->write('Recurring Price: ' . $recurring_price);
And here's the template code for displaying the radio buttons:

Code: Select all

            {% if recurrings %}
<hr>
{#<h3>{{ text_payment_recurring }}</h3>#}
<div class="form-group required">
    <label>
        <input type="radio" name="recurring_id" value="0" checked="checked" />
        One-time purchase: {{ price }}
    </label>
    <br>
    {% for recurring in recurrings %}
    <label>
        <input type="radio" name="recurring_id" value="{{ recurring.recurring_id }}" />
        {{ recurring.name }}: {{ recurring.price }}
    </label>
    <br>
    {% endfor %}
    <div class="help-block" id="recurring-description"></div>
</div>
{% endif %}
P.s attached are references images.
Thank you in advance for your help!

Thanks for your reply but with this approach you are totally diverted from the original opencart code and also converting the original string into Array.


i had this approach in my mind too
Controller

Code: Select all

$recurrings_data = [];

foreach ($products as $product) {
    if ($product['recurring']) {
        // ... other code as before ...

        $recurrings_data[] = [
            'name' => "Test recurring charges:", // Modify as needed
            'price' => $recurring_price,
            'description' => $recurring
        ];
    }
}

$data['recurrings_data'] = $recurrings_data;
twig

Code: Select all

{% if recurrings_data %}
<hr>
<div class="form-group required">
    <label>
        <input type="radio" name="recurring_id" value="0" checked="checked" />
        One-time purchase: {{ price }}
    </label>
    <br>
    {% for recurring_data in recurrings_data %}
    <label>
        <input type="radio" name="recurring_id" value="{{ recurring_data.recurring_id }}" />
        {{ recurring_data.name }}: {{ recurring_data.price }}
    </label>
    <br>
    {% endfor %}
    <div class="help-block" id="recurring-description"></div>
</div>
{% endif %}

I have tried your proposed solution as well but then the issue is that
i start getting error like when visiting the cart view page notices can be solve with

Code: Select all

if (isset($product['recurring']) && $product['recurring']) {
and also notice that Recurring options: Array doesn't hold any value at all and the twig is not rendering anything at all.

2023-08-18 11:36:06 - PHP Notice: Undefined index: recurring in /home/xyz/public_html/catalog/controller/checkout/cart.php on line 123
2023-08-18 11:36:06 - PHP Warning: Invalid argument supplied for foreach() in /home/xyz/public_html/catalog/controller/checkout/cart.php on line 123
2023-08-18 11:36:06 - Recurring options: Array
