PHP Warning – Debug.log

Hi,

I wanted to set a different Reply To email ID to the email sent by your plugin.

I tried using multiple code snippets which work WELL with default Woocommerce emails but seem to have a problem with your plugin email.

Code1

add_filter( 'woocommerce_email_headers', 'dcwd_woocommerce_email_headers', 10, 4 );
function dcwd_woocommerce_email_headers( $header, $email_id, $email_for_obj, $email_class ) {
	if ( 'ywraq_email' == $email_id ) {
	$header = 'Reply-to: [email protected]' . "\r\n";
	}
	return $header;
}

Code2

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

When testing with BOTH code snippets separately, I get the below error in my local installation.

[12-Jun-2020 10:51:24 UTC] PHP Warning:  strpos() expects parameter 1 to be string, array given in F:\laragon\www\iGMS\wp-includes\pluggable.php on line 240

[12-Jun-2020 10:51:24 UTC] PHP Notice:  Undefined offset: 1 in F:\laragon\www\iGMS\wp-includes\pluggable.php on line 248

This warning is shown ONLY when I trigger the Quote email.

Please review and guide me on how to fix this. Please let me know in case you require any additional information.

Thanks
