Custom Activation Email

Hi, Alo.

I’m trying to create a mu-plugin to send a custom activation email based on a “activation.php” (html + images) file, but of course it doesn’t work. Do you have any idea why? I copied the entire section from the alo-easymail-mailer.php file and edited it to no avail.

<?php

function alo_em_handle_custom_activation_email ( $args ) {
	// $args['to'], $args['subject'], $args['message'], $args['headers'], $args['attachments']

	// Check based on $args['subject']; more attrs in $args['message']
	global $_config;
	/*
	 * 1) Activation e-mail
	 */
	if ( strpos ( "#_EASYMAIL_ACTIVATION_#", $args['subject'] ) !== false) {

		// Get the parameters stored as a query in $args['message']
		$defaults = array( 'lang' => '', 'email' => '',	'name' => '', 'unikey' => '' );
		/* // replaced 'wp_parse_args' because use urlencode and stripslashes, so affect emails with '+' chars
		$customs = wp_parse_args( $args['message'], $defaults );
		extract( $customs, EXTR_SKIP );
		*/
		$pars = array();
		$raw = explode('&', $args['message']);
		foreach ($raw as $section)
		{
			if (strpos($section, '=') !== false)
			{
				list($key, $value) = explode('=', $section);
				$pars[$key] = $value;
			}
		}
		$customs = array_merge( $defaults, $pars );
		extract( $customs, EXTR_SKIP );

		// Subject
		if ( $subject_text = alo_em_translate_option ( $lang, 'alo_em_txtpre_activationmail_subj', true ) ) {
			$subject = $subject_text;
		} else {
			$subject = alo_em___( __("This is a custom activation email", "alo-easymail" ) );
		}
		$args['subject'] = $subject;

		// Content
		if ( $content_txt = alo_em_translate_option ( $lang, 'alo_em_txtpre_activationmail_mail', true ) ) {
			$content = $content_txt;
		} else {
		$content = file_get_contents(WP_CONTENT_DIR . '/uploads/activation.php');
		}

		$sub_vars = $email ."|" /*$div_email[0] . "|" . $div_email[1] . "|" */ . $unikey . "|" . $lang;

		//$sub_vars = $subscriber->ID . "|" . $subscriber->unikey;
		$sub_vars = urlencode( base64_encode( $sub_vars ) );
		$sub_link = add_query_arg( 'emact', $sub_vars, alo_em_translate_home_url ( $lang ) );

		$content = str_replace ( "%ACTIVATIONLINK%", $sub_link, $content );

		$args['message'] = $content;
	}
	return $args;
}

add_filter('wp_mail', 'alo_em_handle_custom_activation_email');
?>

Thank you.
