<h4>Example Usage</h4>
<p><strong>Gutenberg Blocks:</strong><br />

<p><strong>Shortcodes:</strong><br />
    [nostr_zap pubkey=”npub1abc…” url=””]<br />
    [nostr_post eventid=”note1abc…”]<br />
    [nostr_profile pubkey=”npub1abc…”]<br />
    [nostr_profile_badge pubkey=”npub1abc…”]<br />
    [nostr_follow_button pubkey=”npub1abc…”]<br />
    [nostr_like]</p>
<h4>Adding Like and Zap Buttons to All Posts/Pages</h4>
<p>To automatically add Like and Zap buttons to the end of every post and page:</p>
<ol>
<li>Go to <strong>Appearance <span aria-hidden="true" class="wp-exclude-emoji">→</span> Theme Editor</strong> (or use a child theme for safer customization)</li>
<li>Select your active theme (or child theme)</li>
<li>Open <code>functions.php</code></li>
<li>Add the following code at the end of the file:</li>
</ol>
<p>[code]<br />
// Add shortcode to the end of every post and page<br />
function add_shortcode_to_content($content) {<br />
    // Only add in single posts and pages (not homepage or archives)<br />
    if (is_singular([‘post’, ‘page’]) && in_the_loop() && is_main_query()) {<br />
        $shortcode_1 = do_shortcode(‘[nostr_like]’);<br />
        $current_url = esc_url(get_permalink());<br />
        $shortcode_2 = do_shortcode(‘[nostr_zap npub=”[YOUR-NPUB-GOES-HERE]” url=”‘ . $current_url . ‘”]’);</p>
<pre><code>    $content .= '<div class="nostr-shortcode-wrapper">' . $shortcode_1 . '<br/><br/>' . $shortcode_2 . '</div>';
}
return $content;
</code></pre>
<p>}<br />
add_filter(‘the_content’, ‘add_shortcode_to_content’);<br />
[/code]</p>
<p><strong>Important Notes:</strong><br />
* Replace <code>[YOUR-NPUB-GOES-HERE]</code> with your actual Nostr public key (npub format)<br />
* Always use a child theme when modifying theme files to preserve changes during theme updates<br />
* The buttons will only appear on single post and page views, not on archive pages or the homepage</p>

<h3>Development</h3>
<p>This plugin is developed as part of the Nostr Components project. For development, bug reports, and feature requests, please visit the <a href="https://github.com/saiy2k/nostr-components" rel="nofollow ugc">GitHub repository</a>.</p>
<h3>Support</h3>

<h3>Privacy Policy</h3>
<p>This plugin does not collect, store, or transmit any personal data. All Nostr data is fetched directly from public relays and displayed locally on your site. If components fetch data client‑side, visitors’ browsers may directly connect to configured relays (exposing their IP and user agent to those relays). Configure trusted relays accordingly.</p>


Saiy2k Nostr Components

Gutenberg blocks and shortcodes for Nostr web components. Display Nostr zap buttons, follow buttons, posts, profiles.

<p>Nostrtium lets you post from WordPress to <a href="https://nostr.how/en/what-is-nostr" rel="nofollow ugc">nostr</a>.</p>
<p>This version implements basic nostr settings (private key, relays) and provides a metabox in the WordPress Post editing page which is pre-populated with the Post Excerpt and a link to the Post and lets you post the content of that metabox to your configured relays.</p>
<p>You can change the content in the metabox as you like. If you have a good excerpt and post it as-is, it creates a twitter-style “announcement” note on nostr. A lot of nostr clients will render the link to the WordPress post as a nice-looking summary card with featured image and etc. This functionality is probably enough for many use-cases but I have plans to add more functionality to this plugin in the future, including generation of keys; support for NIP-07 browser extensions; separate nostr profiles for individual WP users; support for full, long-form content from WP to nostr; and more.</p>
<p>There are also options (on the settings page) to auto-post to nostr the excerpt, the permalink, or both upon WordPress post publication.</p>
<p>[Note that the private key is stored encrypted in the WordPress database using libsodium cryptography.]</p>
<h3>Support and Development</h3>
<p>Development is taking place on <a href="https://github.com/pjv/nostrtium" rel="nofollow ugc">github</a> and the best (fastest) way to get support is to raise an <a href="https://github.com/pjv/nostrtium/issues" rel="nofollow ugc">issue</a> or start a <a href="https://github.com/pjv/nostrtium/discussions" rel="nofollow ugc">discussion</a> there.</p>
<h3>Requirements</h3>
<p>Some of the included libraries have relatively recent dependency requirements so you will need the following in your WordPress platform:<br />
* PHP 8.1+<br />
* php-gmp module must be installed (<a href="https://computingforgeeks.com/how-to-install-php-on-ubuntu-linux-system/" rel="nofollow ugc">Installation on Ubuntu</a>)<br />
* php-bcmath module must be installed (<a href="https://www.itsolutionstuff.com/post/ubuntu-php-bcmath-extension-install-commands-exampleexample.html" rel="nofollow ugc">Installation on Ubuntu</a>)<br />
* WordPress 6.0+<br />
* Writable uploads directory (on activation, the plugin writes a cryptographic keyfile to a storage directory)</p>
<h3>How to Use</h3>
<ol>
<li>After installing and activating the plugin, go into Settings -> Nostrtium and copy/paste the private key (nsec1…) that you want to post from and tweak the relays to your liking.</li>
<li>Then visit the post editor page for an existing post and at or near the bottom you should see the Nostrtium metabox which is pre-populated with the excerpt and permalink for the post (you can change the content in the metabox as you like before posting):</li>
</ol>
<h3>User Role / Capability Filter</h3>
<p>You can create a filter snippet (in your theme’s functions.php) to choose what user role or capability has access to Nostrtium functionality. The default is <code>edit_posts</code>. Here is a sample snippet that would change it so only adminstrators can see / use the plugin’s functionality:</p>
<pre><code>add_filter ('nostrtium_role', function($role){
    return 'administrator';
});
</code></pre>
