Email From header modification

If you want sent emails to have “From” address in form of “blogname <admin_email>”, you can modify this great plugin as follows. All changes are done in file new-user-approve.php.

1. Insert this code after last function in php file:

public function headers() {
		if ( empty($this->myname) || empty($this->myemail) ) {
				$this->myname = html_entity_decode(get_option('blogname'), ENT_QUOTES);
				$this->myemail = get_option('admin_email');
			}

		if ( function_exists('mb_encode_mimeheader') ) {
			$header['From'] = mb_encode_mimeheader($this->myname, 'UTF-8', 'Q') . " <" . $this->myemail . ">";
			$header['Reply-To'] = mb_encode_mimeheader($this->myname, 'UTF-8', 'Q') . " <" . $this->myemail . ">";
		} else {
			$header['From'] = $this->myname. " <" . $this->myemail . ">";
			$header['Reply-To'] = $this->myname . " <" . $this->myemail . ">";
		}

		$header['Return-path'] = "<" . $this->myemail . ">";
		$header['Content-Type'] = "text/plain; charset=\"". get_option('blog_charset') . "\"";

		// collapse the headers using $key as the header name
		foreach ( $header as $key => $value ) {
			$headers[$key] = $key . ": " . $value;
		}
		$headers = implode("\n", $headers);
		$headers .= "\n";

		return $headers;
	}

2. Find all occurences of code
wp_mail( get_option( 'admin_email' ), $subject, $message );
and
@wp_mail( $user_email, $subject, $message )
and change them to
wp_mail( get_option( 'admin_email' ), $subject, $message, $headers );
and
@wp_mail( $user_email, $subject, $message, $headers );
respectively.

3. Insert following code
$headers = $this->headers();
before all occurences of
wp_mail( get_option( 'admin_email' ), $subject, $message, $headers );
and
@wp_mail( $user_email, $subject, $message, $headers );

4. Find this code
var $_admin_page = 'new-user-approve-admin';
and insert this code after it:

var $myname = '';
var $myemail = '';

This modification is based on code from great Subscribe2 plugin.
