<h3>For Developers (Advanced Customization)</h3>
We’ve included several hooks to allow you to extend the plugin’s functionality. Here are some examples of what you can do.
Filters
<code>engage_widget_auto_display_post_types</code> 
Modify the list of post types where buttons are automatically displayed.
<pre><code>add_filter( 'engage_widget_auto_display_post_types', 'add_my_cpt_for_voting' );
function add_my_cpt_for_voting( $post_types ) {
 // Add support for a 'portfolio' custom post type
 $post_types[] = 'portfolio';
 return $post_types;
}
</code></pre>
<code>engage_widget_render_buttons_html</code> 
Filter the final HTML of the buttons for posts.
<pre><code>add_filter( 'engage_widget_render_buttons_html', 'my_custom_post_buttons_wrapper', 10, 2 );
function my_custom_post_buttons_wrapper( $html, $post_id ) {
 return '<div class="my-wrapper">' . $html . '</div>';
}
</code></pre>
<code>engage_widget_render_comment_buttons_html</code> 
Filter the final HTML of the buttons for comments.
<pre><code>add_filter( 'engage_widget_render_comment_buttons_html', 'my_custom_comment_buttons_wrapper', 10, 2 );
function my_custom_comment_buttons_wrapper( $html, $comment_object ) {
 return '<div class="my-wrapper">' . $html . '</div>';
}
</code></pre>
<code>engage_widget_user_can_vote</code> 
Add custom permission logic to prevent a vote. Return <code>false</code> to block the vote.
<pre><code>add_filter( 'engage_widget_user_can_vote', 'prevent_voting_on_own_post', 10, 4 );
function prevent_voting_on_own_post( $permission, $item_type, $item_id, $user_id ) {
 if ( $item_type === 'post' && $user_id > 0 ) {
 if ( get_post_field( 'post_author', $item_id ) == $user_id ) {
 return false; // Prevent users from voting on their own posts
 }
 }
 return $permission;
}
</code></pre>
Actions
<code>engage_widget_after_vote_processed</code> 
Fire a custom action after a vote is successfully recorded.
<pre><code>add_action( 'engage_widget_after_vote_processed', 'my_custom_action_on_vote', 10, 4 );
function my_custom_action_on_vote( $item_type, $item_id, $vote, $user_id ) {
 if ( $item_type === 'post' && $vote === 'like' ) {
 // Example: Send a notification or update a transient
 error_log( "User {$user_id} liked post {$item_id}." );
 }
}
</code></pre>
