Creating a Custom Shortcode Class

To create a custom shortcode in WooCommerce with YayMail, you’ll need to use the BaseShortcode class provided by YayMail as a starting point. Here’s a clear example to help you set up your own custom shortcode class

  1. Extending BaseShortcode: 

    class YourNewShortcodes extends \YayMail\Abstracts\BaseShortcode {

    private static $instance;
    
    public static function instance() {
	if ( null === static::$instance ) {
		static::$instance = new static();
	}
	return static::$instance;
    }

    protected function __construct() {
        /**
        * This refers to the array of template IDs where shortcodes can be applied.
        * We can assign it in 1 of 4 ways
        * 1. Special Array Templates ID: Examples include new_order, customer_processing_order.
        * 2. YAYMAIL_WITH_ORDER_EMAILS: Shortcodes applicable only for templates containing order information.
        * 3. YAYMAIL_NON_ORDER_EMAILS: Shortcodes applicable only for templates without order information.
        * 4. YAYMAIL_ALL_EMAILS: Shortcodes applicable to all email templates.
        */
        $this->available_email_ids = [ YAYMAIL_ALL_EMAILS ];
        parent::__construct();
    }
    
    public function get_shortcodes() {
     // Define your function here
    }
}

    Begin by defining a new class that extends the BaseShortcode class provided by YayMail. Make sure to include essential variables and methods needed for the custom shortcode to work properly.

    Function: get_shortcodes 

    public function get_shortcodes() {    
    $shortcodes = [];

    $shortcodes[] = [
        'name'        => 'new_shortcode_1',
        'description' => 'Custom shortcode 1',
        'group'       => 'Custom Shortcode',
        'callback'    => [ $this, 'new_shortcode_1_render_function' ],
    ];

    $shortcodes[] = [
        'name'        => 'yaymail_new_shortcode_2',
        'description' => 'Custom shortcode 2',
        'attributes'  => [
            'text_link' => 'here',
        ],
        'group'       => 'Custom Shortcode',
        'callback'    => [ $this, 'new_shortcode_2_render_function' ],
    ];

    return $shortcodes;
}

    The get_shortcodes function creates a list of shortcodes. Each shortcode follows this structure:

    When setting up a shortcode, include these key fields:

    • Name: A unique identifier for the shortcode.

    • Description: A short explanation of what the shortcode does.

    • Group: A category to organize related shortcodes together.

    • Callback: The function that generates the shortcode’s output.

    • Attributes (optional): Custom properties, like text_link or color, to enhance the shortcode’s functionality.

  3. Callback function for a shortcode 

    public function new_shortcode_1_render_function( $data ) {
    $render_data           = isset( $data['render_data'] ) ? $data['render_data'] : [];
    $is_placeholder        = isset( $data['is_placeholder'] ) ? $data['is_placeholder'] : false;
    $is_sample             = isset( $render_data['is_sample'] ) ? $render_data['is_sample'] : false;
    $is_customized_preview = isset( $render_data['is_customized_preview'] ) ? $render_data['is_customized_preview'] : false;

    $content            = 'Shortcode content sample';

    return $content;
}

public function new_shortcode_2_render_function( $data, $shortcode_atts = [] ) {
    $template = ! empty( $data['template'] ) ? $data['template'] : null;
    $is_placeholder = isset( $data['is_placeholder'] ) ? $data['is_placeholder'] : false;
    $text_link = isset( $shortcode_atts['text_link'] ) ? $shortcode_atts['text_link'] : '';

    if ( empty( $template ) ) {
        $text_link_color = YAYMAIL_COLOR_WC_DEFAULT;
    } else {
        $text_link_color = $template->get_text_link_color();
    }
    return '<a style="color: ' . esc_attr( $text_link_color ) . ';" href="' . esc_url( get_home_url() ) . '"> ' . $text_link . ' </a>';
}

    This function fetches content for displaying shortcodes in the YayMail Editor and in actual emails. It uses two parameters: data and shortcode_atts (for shortcodes with attributes, if applicable).

    Variables:

    • data: Contains key properties like render_data, template, and is_placeholder.

    • shortcode_atts: An array of attributes defined for the shortcode in the get_shortcodes function.

    • render_data: Holds important details, such as order, is_sample, and is_customized_preview in the YayMail Editor. It also includes data from the get_content_html function when an actual email is sent.

    Email render data
    Email render data

    • is_placeholder: (Boolean) Indicates whether the value should be treated as a placeholder. Returns true if it is a placeholder, false otherwise.

    • is_sample: (Boolean) Returns true when a sample order is selected in the YayMail Editor, false otherwise.

    • is_customized_preview: (Boolean) Returns true when sending a test email or previewing an email in the YayMail Editor, false otherwise.

We’ve followed the steps provided, and the file now correctly includes the use YayMail\Abstracts\BaseShortcode statement.
