Im on woocommerce and are trying by snipets, get the value of all fields to send to adroid app with json.

The trouble its, that i cant capture the values of custom fields on check out. I tried by plugin and snippet create the field but, i cant recover the values to send to json

the field was created with that snipet

add_action( 'woocommerce_after_order_notes', 'my_custom_checkout_field' );



function my_custom_checkout_field( $checkout ) {



echo '<div id="my_custom_checkout_field"><h2>' . __('My Field') . '</h2>';



woocommerce_form_field( 'my_field_name', array(

    'type'          => 'text',

    'class'         => array('my-field-class form-row-wide'),

    'label'         => __('Fill in this field'),

    'placeholder'   => __('Enter something'),

    ), $checkout->get_value( 'my_field_name' ));



echo '</div>';



}

when try to create the json with that snipet i can get all standard woo values but i cant get the custom field

function action_woocommerce_order_status_completed( $array ) { 



$order = wc_get_order( $order_id );

$url = 'localhost/wp/recolector.php';



//Initiate cURL.

$ch = curl_init($url);



// now you can get the data from $product array

};



 //The JSON data.

$jsonData = array(

'email' => $order->get_billing_email(),

'first_name'=> $order->get_billing_first_name(),

'last_name' => $order->get_billing_last_name(),

'phone'=>$order->get_billing_phone()(),

'address'=>$order->get_billing_address_1(),

'city'=>$order->get_billing_city(),

'province'=>$order->get_billing_state(),

'country'=>$order->get_billing_country(),

'order'=>$order->get_order_number()

);



//Encode the array into JSON.

$jsonDataEncoded = json_encode($jsonData);



//Tell cURL that we want to send a POST request.

curl_setopt($ch, CURLOPT_POST, 1);



//Attach our encoded JSON string to the POST fields.

curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonDataEncoded);



//Set the content type to application/json

curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json')); 



//Execute the request

$result = curl_exec($ch);





};



// add the action

add_action( 'woocommerce_order_status_completed', 'action_woocommerce_order_status_completed', 10, 1 ); 

well how supose can add my_field_name to json?

Thanks for help.

There are some mistakes and missing things in your code. Try the following instead:

// Display a custom checkout field

add_action( 'woocommerce_after_order_notes', 'my_custom_checkout_field' );

function my_custom_checkout_field( $checkout ) {

    echo '<div id="my_custom_checkout_field"><h2>' . __('My Field') . '</h2>';



    woocommerce_form_field( '_custom_field', array(

        'type'          => 'text',

        'class'         => array('my-custom-field form-row-wide'),

        'label'         => __('Fill in this field'),

        'placeholder'   => __('Enter something'),

        ), $checkout->get_value( '_custom_field' ));



    echo '</div>';

}



// Save the custom checkout field in the order meta

add_action( 'woocommerce_checkout_create_order', 'save_order_custom_meta_data', 10, 2 );

function save_order_custom_meta_data( $order, $data ) {

    if ( isset($_POST['_custom_field']) )

        $order->update_meta_data('_custom_field', sanitize_text_field( $_POST['_custom_field'] ) );

}





add_action( 'woocommerce_order_status_completed', 'action_on_order_status_completed', 10, 2 ); 

function action_on_order_status_completed( $order_id, $order ) { 

    // The order data (array)

    $data = array(

        'email'         => $order->get_billing_email(),

        'first_name'    => $order->get_billing_first_name(),

        'last_name'     => $order->get_billing_last_name(),

        'phone'         => $order->get_billing_phone()(),

        'address'       => $order->get_billing_address_1(),

        'city'          => $order->get_billing_city(),

        'province'      => $order->get_billing_state(),

        'country'       => $order->get_billing_country(),

        'order'         => $order->get_order_number()

    );



    // Get the custom field value (and add it if not empty)

    if( $custom_field = $order->get_meta('_custom_field') ) {

        // Add it to the array

        $data['custom_field'] = $custom_field;

    }



    //Encode the array into JSON.

    $json_data = json_encode( $data ); 



    // The Url

    $url = 'localhost/wp/recolector.php';



    //Initiate cURL.

    $ch = curl_init($url);



    //Tell cURL that we want to send a POST request.

    curl_setopt($ch, CURLOPT_POST, 1);



    //Attach our encoded JSON string to the POST fields.

    curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonDataEncoded);



    //Set the content type to application/json

    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json')); 



    //Execute the request

    $result = curl_exec($ch);



    // Set the return result in the order as custom meta data (if needed)

    $order->update_meta_data('_curl_result', $result );

    $order->save();

}

It should better work now.
