Hello,

I made a button below each post for sending a message to the post author. But I need also that the subject line fills automatically with the post title and ID.

This is the code I have now:

/**
 * Get a link to send PM to the given User.
 *
 * @param int $user_id user id.
 *
 * @return string
 */
function buddydev_get_send_private_message_to_user_url( $user_id ) {
    return wp_nonce_url( bp_loggedin_user_domain() . bp_get_messages_slug() . '/compose/?r=' . bp_core_get_username( $user_id ));
}

/**
 * Shortcode [bp-pm-button username=optional_some_user_name]
 *
 * @param array $atts shortcode attributes.
 * @param string $content content.
 *
 * @return string
 */
function buddydev_private_message_button_shortcode( $atts, $content = '' ) {

$atts = shortcode_atts( array(
'user_id'   => '',
'username'  => '',
'label'     => 'Send Private Message',
), $atts );

$user_id = absint( $atts['user_id'] );
$user_login = $atts['username'];

// if the username is given, override the user id.
if ( $user_login ) {
$user = get_user_by( 'login', $user_login );
if ( ! $user ) {
return '';
}
$user_id = $user->ID;
}
  
if ( ! $user_id ) {
if ( ! in_the_loop() ) {
return '';
}

$user_id = get_the_author_meta('ID' );
}

}

add_shortcode( 'bp-pm-button', 'buddydev_private_message_button_shortcode' );

/**
 * Get the button for the post author.
 *
 * @return string
 */
function buddydev_get_author_private_message_button() {
    if ( ! in_the_loop()) {
        return '';
    }
 
    $user_id = get_the_author_meta('ID');
    // can't pm to themselves.
    if ( bp_loggedin_user_id() === $user_id ) {
        return '';
    }
 
    return sprintf('<a class="sg-popup-id-11605" id="private-message-bp" href="%1$s">%2$s</a>', buddydev_get_send_private_message_to_user_url( $user_id ), 'Send Private Message' );
}

/**
 * Do you want to automatically inject the button on each post?
 *
 * @param string $entry_content entry content.
 *
 * @return string
 */
function buddydev_inject_private_message_button( $entry_content ) {
    // append at the bottom.
    $entry_content = $entry_content . buddydev_get_author_private_message_button();
    // if you want to only do it on single entry pages(single post etc), you can comment the above line
    // and uncomment the block below
    /* if ( is_singular() ) {
        $entry_content = $entry_content . buddydev_get_author_private_message_button();
    } */
 
    // want to test for a post type, you may use is_singular('post_type_name') instead of is_singular()
    return $entry_content;
}
// append to the post entry?
add_filter( 'the_content', 'buddydev_inject_private_message_button' );

Thank you!
