WooCommerce Change User Role on Purchase of Specific Product

It looks like the if should be inside the foreach, otherwise the if tests only the last value for $product_id, not all of them.

Thanks lorro, Your suggestion worked perfectly ! So here i am again pasting the working code for others reference…

Really thanks for the help.

So now correct code is for the above said requirement :-

<?php
function lgbk_add_member( $order_id ) {

$order = new WC_Order( $order_id );
$items = $order->get_items();

foreach ( $items as $item ) {
    $product_name = $item['name'];
    $product_id = $item['product_id'];
    $product_variation_id = $item['variation_id'];

if ( $order->user_id > 0 && $product_id == '33' ) {
	update_user_meta( $order->user_id, 'paying_customer', 1 );
	$user = new WP_User( $order->user_id );

	// Remove role
	$user->remove_role( 'subscriber' ); 

	// Add role
	$user->add_role( 'contributor' );
	}

}

}
add_action( 'woocommerce_order_status_completed', 'lgbk_add_member' );
?>

Hi,

That’s what I am looking for
I don’t manage to make it work, can you please help
1 – You place this function in Theme function.php, right ?
2 – I had a blank page including <?php ?> so is it the right function :

function lgbk_add_member( $order_id ) {

$order = new WC_Order( $order_id );
$items = $order->get_items();

foreach ( $items as $item ) {
$product_name = $item[‘name’];
$product_id = $item[‘product_id’];
$product_variation_id = $item[‘variation_id’];

if ( $order->user_id > 0 && $product_id == ’33’ ) {
update_user_meta( $order->user_id, ‘paying_customer’, 1 );
$user = new WP_User( $order->user_id );

// Remove role
$user->remove_role( ‘subscriber’ );

// Add role
$user->add_role( ‘contributor’ );
}

}

}
add_action( ‘woocommerce_order_status_completed’, ‘lgbk_add_member’ );

3 – The only value I need to change to adapt to my case is product_id “$product_id == ‘myid”, right ?

Thanks for help

It is not a good idea to edit your theme functions.php. This is because any edits will be overwritten the next time the theme is updated.

You should make a child theme:
https://codex.www.ads-software.com/Child_Themes

The above function goes in functions.php for the child theme.

The first line of functions.php is <?php There is no need for a closing
?> tag in this case.

Yes, just change the id of the product.

Thanks for your answer and advice

Hello,
is there a way to achive the same thing but not for a specific product but for more products like from a certain category or better with a specific keyword?

I tried to use this code however its not working.

1 – have used the code exactly how its mentioned

<?php
function lgbk_add_member( $order_id ) {

$order = new WC_Order( $order_id );
$items = $order->get_items();

foreach ( $items as $item ) {
    $product_name = $item['name'];
    $product_id = $item['product_id'];
    $product_variation_id = $item['variation_id'];

if ( $order->user_id > 0 && $product_id == '33' ) {
	update_user_meta( $order->user_id, 'paying_customer', 1 );
	$user = new WP_User( $order->user_id );

	// Remove role
	$user->remove_role( 'subscriber' ); 

	// Add role
	$user->add_role( 'contributor' );
	}

}

}
add_action( 'woocommerce_order_status_completed', 'lgbk_add_member' );
?>

2 – created a child theme, and created a file functions.php
3 – added the specific product id identified using the link like
wp-admin/post.php?post=3796&action=edit where 3796 is the product code. tried a couple of other product codes as well.
4 – identified the exact user role slug and updated it, tried a couple of other roles as well, just to ensure its not the role In my case it is the user role ‘customer’ that changes to ‘test_role’

What could have gone wrong?

Do you have a security plugin or feature that prevents the creation of new users?

Try deactivating other plugins to make sure none are interfering.

Add the line:

var_dump($order_id);

after the function line to make sure $order_id is something sensible and not null. Repeat after each line with the variable that has changed to try to find out where its not working.
