WordPress Modifications to "functions.php"

The file 'functions.php' is part of the thema you are using and should be in the thema's folder. The thema here is twenty-twenty-four-wjv. Where not mentioned otherwise, the modifications in these paragraphs are inserted in the functions.php -file of this theme. Make sure you create and use a child-theme because any changes will be overwritten when the thema is updated. 

sudo nano /var/www/wordpress/wp-content/themes/twenty-twenty-four-wjv/functions.php

Include field values in page text with shortcode

This allows you to include a first_name or other fields in a weppage by using a shortcode. 

/**
 * User Meta Shortcode handler
 * usage: [USER_META user_id=1 meta="first_name"]
 *    or: [USER_META meta="first_name"]
 * @param  array $atts
 * @param  string $content
 * @return string
 */
function wjv_meta_shortcode_handler($atts,$content=null) {
	if (isset($atts['user_id']) || array_key_exists('user_id', $atts)) {
		$c_user_id = $atts['user_id'];
	}
	else {
		$c_user_id = wp_get_current_user()->ID;
	}
	return esc_html(get_user_meta($c_user_id, $atts['meta'], true));
}
add_shortcode('USER_META', 'wjv_meta_shortcode_handler');

Use Custom Profile for non-admin users

After a normal user is logged in to the website the WordPress toolbar would appear. The following wil hide the toolbar in this case. 

/**
 * Custom profile for subscribers, this makes sure all Profile-links go to your designated page.
 */
add_action( 'load-profile.php', 'rpa_customprofile_check' );
function rpa_customprofile_check() {
  if ( ! current_user_can( 'manage_options' ) ) {
    wp_redirect( add_query_arg( array( 'pcustomprofile' => 1), site_url('?page_id=269&a=edit') ) );	
    exit();
  }
}

Hide toolbar

After a normal user is logged in to the website the WordPress toolbar would appear. The following wil hide the toolbar in this case. 

/**
 * Limiting toolbar to only users who can "manage_options" 
 * such as admins in a default WP install.
 */
if ( ! current_user_can( 'manage_options' ) ) {
	add_filter( 'show_admin_bar', '__return_false' );
}

Allow subscribers to view private posts

Blocked posts would still be visible as a title and a summary to the public, you can limit the summary with the "more" tag. Clicking the post brings a signed-in subscriber to the whole content or else to a sign-in message.

By allowing "private" posts to signed-in members you can still hide them completely from the public but show them to subscribers.

Info: 

/**
 * Make Private Posts visible to Subscribers
 */
function wjv_private_posts_subscribers(){
	$subRole = get_role( 'subscriber' );
	$subRole->add_cap( 'read_private_posts' );
	$subRole->add_cap( 'read_private_pages' );
}
add_action( 'init', 'wjv_private_posts_subscribers' );

Add Email function

WP-Members uses the native WP function wp_mail to send all emails. This is a native WordPress function and is generally robust.

Info: 

/**
 * E-mail function
 * NB: constants in wp-config.php
 */
function wjv_send_smtp_email( $phpmailer ) {
  $phpmailer->isSMTP();
  $phpmailer->Host =       SMTP_HOST;
  $phpmailer->Username =   SMTP_USER;
  $phpmailer->Password =   SMTP_PASSWORD;
  $phpmailer->From =       SMTP_FROM;
  $phpmailer->FromName =   SMTP_FROMNAME;
  $phpmailer->Port =       SMTP_PORT;
  $phpmailer->SMTPAuth =   SMTP_AUTH;
  $phpmailer->SMTPSecure = SMTP_SECURE;
  $phpmailer->SMTPDebug =  SMTP_DEBUG;
}
add_action( 'phpmailer_init', 'wjv_send_smtp_email' );

The best place for configuration is "wp-config.php": 

sudo nano /var/www/wpvvb/wp-config.php
/**
 * Define constants for SMTP settings
 * SMTP Port for SSL: 465
 * SMTP Port for TLS/STARTTLS: 587
 */
define( 'SMTP_HOST',     'smtp.mail.yahoo.com' );
define( 'SMTP_USER',     'user1@yahoo.com' );
define( 'SMTP_PASSWORD', '****' );
define( 'SMTP_FROM',     'user1@yahoo.com' );
define( 'SMTP_FROMNAME', 'WordPress - user1@yahoo.com' );
define( 'SMTP_PORT',      '587' );
define( 'SMTP_AUTH',      true );
define( 'SMTP_SECURE',    'tls' );
define( 'SMTP_DEBUG',     2 );

Add duplicate-button to posts
