I have a frontend submission form, where users can add events to a custom post type. I want to send an email to each user 1 week before this event takes place.

The emails are sent via wp_cron. The function is called with a hook. Its working correctly, but i want to add custom values to the email body.

With my code its not possible to add dynamic value to the body template of my email.

With this function below, i loop through the events post type and get the required data

function leweb_get_events_detail() {      // Query     global $  wp_query;      // Arguments       $  args = array(         'post_type' => 'events',     );      // Start the Query     $  query = new WP_Query( $  args );      // The Loop     if( $  query->have_posts() ) {          $  results = array();          while( $  query->have_posts() ) {              $  query->the_post();                           $  event_date_timestamp = get_post_meta( get_the_ID(), 'event_date_timestamp', true );             $  future_timestamp = strtotime("+1 week");              // Damit wird geprüft ob schon einmal diese Email gesendet wurde             $  notification = get_post_meta( get_the_ID(), 'event_creator_notification' );              if( !in_array( '1week', $  notification )  && $  event_date_timestamp < $  future_timestamp ) {                  $  event_id = get_the_ID();                 $  event_email = get_post_meta( get_the_ID(), 'event_email', true );                  $  results[] = array(                                  'event_id'      => $  event_id,                                  'event_date_timestamp' => $  event_date_timestamp,                                 'event_email'     => $  event_email,                 );              }         }          return $  results;      }      wp_reset_query();  } 

The function below lets me fetch data from the post_meta array

function leweb_get_values_from_post_meta( $  meta = '') {      $  results = leweb_get_events_detail();      $  values = array();     foreach( $  results as $  key => $  value ){          $  values[] = $  value[ $  meta ];      }      return $  values; } 

The function below is called from wp_cron. The email is sent to all recipients who match the above conditions and a value is added to the post meta, to prevent multiple sends of this email.

function leweb_send_mail_to_author() {       // Alle Emails aus dem Array auslesen und für das BCC Feld im Email Header vorbereiten     $  emails = leweb_get_values_from_post_meta( 'event_email');      if ( !empty( $  emails ) ) {          $  emails = 'BCC: ' . implode( ',', $  emails );          // Email senden         $  to = '';         $  subject = 'Dein Event findet bald statt!';         $  body = file_get_contents( get_stylesheet_directory() . '/templates/email/event-creator-notification.php');         $  headers = array( 'Content-Type: text/html; charset=UTF-8','From: Example <office@example.com>', $  emails );          wp_mail( $  to, $  subject, $  body, $  headers );          // Wert in post_meta eintragen um die Mehrfachsendung zu verhindern         $  post_id = leweb_get_values_from_post_meta( 'event_id');          foreach( $  post_id as $  id ) {              add_post_meta( $  id, 'event_creator_notification', '1week' );          }      }  } 

After i coded this i figured out, its not possible to send dynamic content in the body of my email. The only way to achieve this, is to call the wp_mail() in foreach. But this would be heavy i think? Its possible that this job sends up to hundred emails per run in the future…

So i was wondering if there is another way to do this clean?

Thanks for your opinions, i know its a bit complex, but i dont have any other ideas…
