## Introduction

Would you like to create a Smart Tag Site URL? Perhaps you’d like to re-use this Smart Tag in your email notifications or confirmation messages? In this tutorial, we’ll show you how you can create a Smart Tag for your site URL but also how and where to place it inside your notifications.

## Adding the Snippet

To begin, we’re going to add our snippet to the site first. If you need any help with how and where to add snippets, [please be sure to review this helpful documentation](https://wpforms.com/developers/how-to-add-custom-php-or-javascript-for-wpforms/ "How to Add Custom PHP or JavaScript for WPForms").

```

/**
 * Process the Smart Tag.
 *
 * @link   https://wpforms.com/developers/how-to-create-a-smart-tag-for-site-url/
 */

function wpf_dev_register_site_smarttag( $tags ) {

    // Key is the tag, item is the tag name.
    $tags[ 'site_url' ] = 'Site URL';

    return $tags;
}
add_filter( 'wpforms_smart_tags', 'wpf_dev_register_site_smarttag', 10, 1 );

/**
 * Process the Smart Tag.
 *
 * @link   https://wpforms.com/developers/how-to-create-a-smart-tag-for-site-url/
 */

function wpf_dev_process_site_url_smarttag( $content, $tag ) {

    // Only run if it is our desired tag.
    if ( 'site_url' === $tag ) {

        // Assign the site URL to the $url variable
        $url = get_site_url();

        // Replace the tag with our link.
        $content = str_replace( '{site_url}', $url, $content );

    }

    return $content;
}
add_filter( 'wpforms_smart_tag_process', 'wpf_dev_process_site_url_smarttag', 10, 2 );
```

This snippet has two functions. The first is just registering that we’re going to create a Smart Tag called **site\_url** however, the text we’ll see inside the form builder for this particular Smart Tag is **Site URL**.

The second function will look for the current site URL with the WordPress function **get\_site\_url();** and then we’ll pass that inside the function and assign the **$url** variable inside the Smart Tag.

## Using the Smart Tag

For the purpose of this documentation, we’re placing a thank you image inside each email notification that our visitors receive after completing our form. To do this, we’ll head to the Notifications tab and add this after the **{all\_fields}** Smart tag in our notification message.

Just add your HTML link and image source to your **Email Message** on your **Notifications** tab.

```

```

 */

function wpf_dev_register_site_smarttag( $tags ) {

    $tags[ 'permalink' ] = 'Permalink';

    return $tags;
}
add_filter( 'wpforms_smart_tags', 'wpf_dev_register_site_smarttag', 10, 1 );

/**
 * Process the Smart Tag.
 *
 * @link   https://wpforms.com/developers/how-to-create-a-smart-tag-for-site-url/
 */

function wpf_dev_process_site_url_smarttag( $content, $tag ) {

    // Only run if it is our desired tag.
    if ( 'permalink' === $tag ) {

        // Assign the site URL to the $url variable
	$url = substr( get_permalink(), strlen( home_url('/') ) );

        // Replace the tag with our link.
        $content = str_replace( '{permalink}', $url, $content );

    }

    return $content;
}
add_filter( 'wpforms_smart_tag_process', 'wpf_dev_process_site_url_smarttag', 10, 2 );
```
