    Hi,

    I am getting the below PHP Notice in debug.log

    WP: 5.4.2
    Woocommerce: 4.2.0
    Email Log: 2.3.2

    [11-Jun-2020 11:32:25 UTC] PHP Notice: Array to string conversion in F:\laragon\www\iGMS\wp-content\plugins\email-log\include\Util\helper.php on line 171

    I am also seeing the below warnings:

    [11-Jun-2020 11:38:16 UTC] PHP Warning:  strpos() expects parameter 1 to be string, array given in F:\laragon\www\iGMS\wp-includes\pluggable.php on line 240
[11-Jun-2020 11:38:16 UTC] PHP Warning:  trim() expects parameter 1 to be string, array given in F:\laragon\www\iGMS\wp-includes\pluggable.php on line 248
[11-Jun-2020 11:38:16 UTC] PHP Notice:  Undefined offset: 1 in F:\laragon\www\iGMS\wp-includes\pluggable.php on line 248

    I am using the below code to change the Reply to address on outgoing emails.

    add_filter( 'woocommerce_email_headers', 'add_reply_to_certain_emails', 10, 2 );
function add_reply_to_certain_emails ($headers, $object ) {
	$add_reply_to = array(
		'customer_on_hold_order',
		'customer_processing_order',
		'customer_completed_order',
		'customer_refunded_order',
		'customer_invoice',
		'customer_note',
		'customer_reset_password',
		'customer_new_account',
		);
	if ( in_array( $object, $add_reply_to ) ) {
		$headers = array( 
			$headers,
			'Reply-to: Domain.com <[email protected]>' ."\r\n",
			);
	}
	return $headers;

    Please review and guide me on what changes to make. Please let me know in case you require any additional information.

    Thanks a lot

    Hello @koolpal

    The warning is happening because of an issue in your code and not because of WooCommerce or our Email Log plugin.

    Basically the problem is that the woocommerce_email_headers filter filters a string, but in your function you are converting it into an array. See https://github.com/woocommerce/woocommerce/blob/master/includes/emails/class-wc-email.php#L421 where this filter is getting used.

    You should change your function to the following and this will fix the issue for you.

    add_filter( 'woocommerce_email_headers', 'add_reply_to_certain_emails', 10, 2 );
function add_reply_to_certain_emails ($headers, $object ) {
	$add_reply_to = array(
		'customer_on_hold_order',
		'customer_processing_order',
		'customer_completed_order',
		'customer_refunded_order',
		'customer_invoice',
		'customer_note',
		'customer_reset_password',
		'customer_new_account',
		);

	if ( in_array( $object, $add_reply_to ) ) {
        $headers .= 'Reply-to: Domain.com <[email protected]>' ."\r\n",
	}
	
    return $headers;
}

    Try it out and let me know if you are still facing any issues.

    Thank you for replying.

    I tried your suggested code and I had to make the following changes to make this work
    1. Change , to ; at end of line 18
    2. Remove remove the . after $headers and change the line to $headers = in line 18

    line 18: $headers = 'Reply-to: Domain.com <[email protected]>' ."\r\n";

    There are no more notices now!

    Thanks a lot!
