Set current user email as $headers From

Hi!

Looking at this my implementation of email headers is not optimal. It’s a bit hard to edit existing fields such as from because they are stored in a continuous array when it should really be an associative one.

Here’s one way to work around it. Haven’t had a chance to test it but the basic idea is to find the “From” header and replace it with a new one:

function filter_email_headers( $headers, $email, $form, $fields ) {
  foreach ( $headers as $i=>$header ) {
    if ( false !== strpos( $header, 'From:' ) ) {
      // Add a copy to client
      $current_user = wp_get_current_user();
      $email = $current_user->user_email;
      $header[ $i ] = 'From: ' . $email;
    }
  }

  return $headers;
}
add_filter( ‘af/form/email/headers/key=FORM_KEY’, ‘filter_email_headers’, 10, 4 );

I’m going to think about how to fix this ??

Hi Fabian,

Thanks for your response.
The code does not work. It does not change the From header.

My main goal was to identify the current logged in user, so I used the filter af/form/email/content (source: https://advancedforms.github.io/filters/af-form-email-content/).

The code below I’m using now meets my goal.

/* Identify user sending this form - put this in functions.php
------------------------------------------------------------------ */
function display_name_in_content( $content, $email, $form, $fields ) {
	// Add some extra text to the end of the content
    $current_user = wp_get_current_user();
    $displayname = $current_user->display_name;
    $content .= ' This message is send by ' . $displayname;
    
    return $content;
}
add_filter( 'af/form/email/content/key=FORM_KEY', 'display_name_in_content', 10, 4 );

Thanks again!
