Get payment gateway related data in Woocommerce - php

Question

I have this code to set WooCommerce variables
// Defining User set variables
$this->title = $this->get_option( 'title' );
$this->description = $this->get_option( 'description' );
$this->instructions = $this->get_option( 'instructions' );
but how to get $this->instructions in thankyou.php WooCommerce template?
I already tried using $order->instructions but then an errors appear
Notice: instructions was called incorrectly. Order properties should
not be accessed directly. Backtrace: require('wp-blog-header.php'),
require_once('wp-includes/template-loader.php'),
include('/themes/startup-company/page.php'), the_content,
apply_filters('the_content'), WP_Hook->apply_filters, do_shortcode,
preg_replace_callback, do_shortcode_tag, WC_Shortcodes::checkout,
WC_Shortcodes::shortcode_wrapper, WC_Shortcode_Checkout::output,
WC_Shortcode_Checkout::order_received, wc_get_template,
include('/plugins/woocommerce/templates/checkout/thankyou.php'),
WC_Abstract_Legacy_Order->__get, wc_doing_it_wrong Please see
Debugging in WordPress for more information. (This message was added
in version 3.0.)
So I tried to see what inside $order, and then I see a long vars that doesn't have the text that I set for $this->instructions in WooCommerce Payment Gateway Plugin that I built myself.

Answer 1

You can get all Woocommerce payment methods with WC_Payment_Gateways class. Then you can get the checkout available payment methods and get the related data this way:
$wc_gateways = new WC_Payment_Gateways();
$payment_gateways = $wc_gateways->get_available_payment_gateways();
// Loop through Woocommerce available payment gateways
foreach( $payment_gateways as $gateway_id => $gateway ){
$title = $gateway->get_title();
$description = $gateway->get_description();
$instructions = property_exists( $gateway , 'instructions' ) ? $gateway->instructions : '';
$icon = $gateway->get_icon();
}
Tested and works in Woocommerce 3+
You can also call an instance of your custom Payment gateway Class and use on it the methods and properties like in the code above… Or you can target a specific payment gateway inside the foreach loop using the $gateway_id in an IF statement.

The above example is great! Here's just another option to show the payment methods in radio inputs or dropdown. The shortcode is [display_payment_methods]. Add code to child theme functions.php or use code snippet plugin. Place shortcode in page/post to view on frontend.
add_shortcode('display_payment_methods','display_payment_methods');
function display_payment_methods(){
global $woocommerce;
$available_gatewayz = WC()->payment_gateways->get_available_payment_gateways();
if ( $available_gatewayz ) { ?>
<form id="add_payment_method" method="post">
<div id="payment" class="woocommerce-Payment">
<ul class="woocommerce-PaymentMethods payment_methods methods">
<?php
// Chosen Method.
if ( count( $available_gatewayz ) ) {
current( $available_gatewayz )->set_current();
}
foreach ( $available_gatewayz as $gatewayz ) {
?>
<li class="woocommerce-PaymentMethod woocommerce-PaymentMethod--<?php echo esc_attr( $gatewayz->id ); ?> payment_method_<?php echo esc_attr( $gatewayz->id ); ?>">
<input id="payment_method_<?php echo esc_attr( $gatewayz->id ); ?>" type="radio" class="input-radio" name="payment_method" value="<?php echo esc_attr( $gatewayz->id ); ?>" <?php checked( $gatewayz->chosen, true ); ?> />
<label for="payment_method_<?php echo esc_attr( $gatewayz->id ); ?>"><?php echo wp_kses_post( $gatewayz->get_title() ); ?> <?php echo wp_kses_post( $gatewayz->get_icon() ); ?></label>
<?php
if ( $gatewayz->has_fields() || $gatewayz->get_description() ) {
echo '<div class="woocommerce-PaymentBox woocommerce-PaymentBox--' . esc_attr( $gatewayz->id ) . ' payment_box payment_method_' . esc_attr( $gatewayz->id ) . '" style="display: none;">';
$gatewayz->payment_fields();
echo '</div>';
}
?>
</li>
<?php
}}
?>
</ul>
<!-- Enabled Payment Methods Dropdown Select -->
<select name="payment_method" class="select_field">
<option selected="selected" disabled="disabled" value="<?php echo esc_attr( $gatewayz->id ); ?>"><?php echo esc_attr( __( 'Select Payment Method' ) ); ?></option>
<?php
$available_gatewayz = WC()->payment_gateways->get_available_payment_gateways();
// Chosen Method.
if ( count( $available_gatewayz ) ) {
current( $available_gatewayz )->set_current();
}
foreach ( $available_gatewayz as $gatewayz ) {
$option = '<option value="' . esc_attr( $gatewayz->id) . '" ';
$option .= ( esc_attr( $gatewayz->id) == $available_gatewayz ) ? 'selected="selected"' : '';
$option .= '>';
$option .= wp_kses_post( $gatewayz->get_title() ) ;
$option .= '</option>';
echo $option;
}
?>
</select>
<?php
}
