Tracking Pixel Location.

Hi Marco, you can disable the default tracking pixel in plugin setting page, then you can use the newsletter content filter to add your tracking pixel.
This is a quick sample, just a starting point:

function custom_alo_em_tracking_pxl ( $content, $newsletter, $recipient ) {
	
	// If $recipient is not defined, don't track (e.g. it's a test email)
	if ( isset( $recipient->ID, $recipient->unikey ) ) {
		
		// This is the default tracking by EasyMail: replace with yours
		$track_vars = $recipient->ID . '|' . $recipient->unikey;
		$track_vars = urlencode( base64_encode( $track_vars ) );
		$tracking_view = '<img src="'. ALO_EM_PLUGIN_URL .'/tr.php?v='. $track_vars .'" width="1" height="1" border="0" alt="" >';
		
		// Insert tracking img before </body> if tag exists, otherwise at the end
		if ( strpos( $content, "</body") !== false ) {
			$content = str_replace( "</body", $tracking_view ."\n</body" , $content );
		} else {
			$content .= $tracking_view;
		}
	} 
	
	return $content;
}
add_filter ( 'alo_easymail_newsletter_content',  'custom_alo_em_tracking_pxl', 20, 3 );

I hope it helps.

Thank you for your help, Alo!

Tracking pixel is added all right, Spamassassin treats it like a normal image.

Unfortunately, it doesn’t track.

I copied tr.php to website root folder, changed “no” to “yes” in the line below,

if ( get_option(‘alo_em_use_tracking_pixel’) == ‘yes’ ) exit;

but it doesn’t track.

I’ll have to check something else…

Thanks.
Marco.

Tracking works all right.

wp_load pointed to non-existent directory ( was ../../../wp-load.php).

define(‘WP_USE_THEMES’, false);
include(‘wp-load.php’);

Thanks again.

Marco
