PHP add conditions within an array variable (WooCommerce API) - php

Question

Take for example the following piece of code from WooCommerce API Documentation. What I am trying to do is add some if conditions within the array. For example, I want the payment_details array to be a part of $data based on some if condition. Is this possible? How?
<?php
$data = [
'order' => [
'payment_details' => [
'method_id' => 'bacs',
'method_title' => 'Direct Bank Transfer',
'paid' => true
],
'billing_address' => [
'first_name' => 'John',
'last_name' => 'Doe',
'address_1' => '969 Market',
'address_2' => '',
'city' => 'San Francisco',
'state' => 'CA',
'postcode' => '94103',
'country' => 'US',
'email' => 'john.doe#example.com',
'phone' => '[phone]'
],
'shipping_address' => [
'first_name' => 'John',
'last_name' => 'Doe',
'address_1' => '969 Market',
'address_2' => '',
'city' => 'San Francisco',
'state' => 'CA',
'postcode' => '94103',
'country' => 'US'
],
'customer_id' => 2,
'line_items' => [
[
'product_id' => 546,
'quantity' => 2
],
[
'product_id' => 613,
'quantity' => 1,
'variations' => [
'pa_color' => 'Black'
]
]
],
'shipping_lines' => [
[
'method_id' => 'flat_rate',
'method_title' => 'Flat Rate',
'total' => 10
]
]
]
];
print_r($woocommerce->post('orders', $data));
?>
The point is, instead of defining the entire array again, I want to put an if condition here:
'order' => [
if ($payment = 'xyz') {
'payment_details' => [
'method_id' => 'bacs',
'method_title' => 'Direct Bank Transfer',
'paid' => true
],
}
else {
'payment_details' => [
'method_id' => 'monopoly',
'method_title' => 'Monopoly',
'paid' => true
],
}
Is it possible to concatenate the array using dot equals? .=
Thanks.

Answer 1

"payment_details" is already part of $data.
To get to it use:
$paymentDetails = $data['order']['payment_details'];
Then you can display it with:
echo $paymentDetails['method_title'];
If you want to use if conditions:
if ($paymentDetails['method_title'] === 'Monopoly money') {
echo 'That will not work';
}
To change the payment details:
$data['order']['payment_details']['method_title'] = 'Changed';
or
$data['order']['payment_details'] = ['method_title' => 'something', 'method_id' => 5, 'paid' => false];

Answer 2

You can define the payment_details in advance and use it in the $data array.
if ($payment = 'xyz') {
$payment_details = array ( 'method_id' => 'bacs',
'method_title' => 'Direct Bank Transfer',
'paid' => true);
}else{
$payment_details = array ( 'method_id' => 'monopoly',
'method_title' => 'Monopoly',
'paid' => true);
}
$data = array (
'order' => array(
'payment_details' => $payment_details,
......
......
)
);
print_r($woocommerce->post('orders', $data));

Answer 3

Answering my own question. This is what I was looking for.
$orderData = [];
if ($payment == 'Monopoly') {
$orderData['order']['payment_details'] = [];
$orderData['order']['payment_details']['method_id'] = 'Monopoly';
$orderData['order']['payment_details']['method_title'] = 'Monopoly';
$orderData['order']['payment_details']['paid'] = true;
$orderData['order']['status'] = 'completed';
}
else {
$orderData['order']['status'] = 'pending';
}
