Resend programmatically a WooCommerce customer_on_hold_order email notification

Question

I noticed that the customer on hold order email is not available so i tried to replace the actions with a single action that would send the appropriate email.

This seems to work except for the on-hold status. I dont see what the difference is between the on-hold and processing case other than its not in the $available_emails in class-wc-meta-box-order-actions.php and I have removed all the others and they still work.

What I am doing wrong? Is it a way to make this possible?

My code is:

    function ulmh_resend1( $actions ) {
    $actions['ulmh_resend'] = __( 'Resend Email', 'text_domain' );
    return $actions;
}
function ulmh_resend2( $order ) {
    $mailer = WC()->mailer();
    $mails = $mailer->get_emails();
    if ($order->has_status( 'on-hold' )) {
    $eml = 'customer_on_hold_order';    
    }elseif ($order->has_status( 'processing' )) {
    $eml = 'customer_processing_order'; 
    }elseif ($order->has_status( 'completed' )) {
    $eml = 'customer_completed_order';  
    } else {
    $eml = "nothing";
    }   
    if ( ! empty( $mails ) ) {
        foreach ( $mails as $mail ) {
            if ( $mail->id == eml ) {
               $mail->trigger( $order->id );
            }
         }
    }
}
function ulmh_resend3( $order_emails ) {
    $remove = array( 'new_order', 'cancelled_order', 'customer_processing_order', 'customer_completed_order', 'customer_invoice' );
    $order_emails = array_diff( $order_emails, $remove );
    return $order_emails;
}   
add_action( 'woocommerce_order_actions', 'ulmh_resend1' );
add_action( 'woocommerce_order_action_ulmh_resend', 'ulmh_resend2' );
add_filter( 'woocommerce_resend_order_emails_available', 'ulmh_resend3' );

What's the question, specifically? What in your code does / doesn't work? — random_user_name, Aug 29 '17 at 01:17
Code works fine if the order is in processing or completed status but no email is sent if in on hold status. No messages appear in the debug log, it just looks as if customer_on_hold_order is not in $mails, but the original email is sent correctly — Bush Al, Aug 29 '17 at 01:27
Sorry Loic, i must have pressed that by mistake - re-ticked now. all good — Bush Al, Mar 31 '18 at 21:58

I have revisited and compacted your code because there where some errors like a typo error in if ( $mail->id == eml ){ for eml as a variable name… Also to get the Order ID from the WC_Order object you should use $order->get_id() method instead of $order->id.

Here is this new functional code:

add_action( 'woocommerce_order_actions', 'ulmh_resend1' );
function ulmh_resend1( $actions ) {
    $actions['ulmh_resend'] = __( 'Resend Email', 'text_domain' );
    return $actions;
}

add_action( 'woocommerce_order_action_ulmh_resend', 'ulmh_resend2' );
function ulmh_resend2( $order ) {
    $wc_emails = WC()->mailer()->get_emails();
    if( empty( $wc_emails ) ) return;

    if ($order->has_status( 'on-hold' ))
        $email_id = 'customer_on_hold_order';
    elseif ($order->has_status( 'processing' ))
        $email_id = 'customer_processing_order';
    elseif ($order->has_status( 'completed' ))
        $email_id = 'customer_completed_order';
    else
        $email_id = "nothing";

    foreach ( $wc_emails as $wc_mail )
        if ( $wc_mail->id == $email_id )
            $wc_mail->trigger( $order->get_id() );
}

add_filter( 'woocommerce_resend_order_emails_available', 'ulmh_resend3' );
function ulmh_resend3( $order_emails ) {
    $remove = array( 'new_order', 'cancelled_order', 'customer_processing_order', 'customer_completed_order', 'customer_invoice' );
    $order_emails = array_diff( $order_emails, $remove );
    return $order_emails;
}

Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

This code is tested in WooCommerce 3+ and works fine now for on-hold order status email notifications, when resending

It was working very perfectly but after updating to woocommerce 3.5.1, only new order emails not being fired. Any idea? Any known bug (I didn't find on woo git)? — Pankaj Verma, Nov 28 '18 at 12:34
Wow, this sure saved me a _lot_ of work when testing a service that affects more than a dozen emails! Thanks! — mpemburn, Nov 08 '19 at 18:06
