How to specify Woocommerce product in a script? - wordpress

Question

This code works for me but it makes adjustments to every subscription on the website. I want to target a particular product or array of products so others are unaffected.
that's issue I have with that code on other subscriptions
add_filter( 'woocommerce_subscriptions_product_price_string', 'my_subs_price_string1', 10, 3 );
function my_subs_price_string1( $subscription_string, $product, $include ) {
/****
var_dump($product); Various variables are available to us
****/
return 'Today ' . wc_price( $product->subscription_sign_up_fee ) .
', a ' . $product->subscription_trial_length . ' ' . $product->subscription_trial_period .
' trial of the product, then an outright purchase of ' . wc_price( $product->subscription_price );
}
EDIT:
I tried using a snippet from the post in the answer below. But for some reason, it just removes the string and doesn't replace chosen string.
Here's the snippet.
function wc_subscriptions_custom_price_string( $pricestring ) {
global $product;
$products_to_change = array( 2212 );
if ( in_array( $product->id, $products_to_change ) ) {
$newprice = str_replace( 'on the 20th day of every 6th month', 'on the 20th November and 20th May', $pricestring );
}
return $newprice;
}
add_filter( 'woocommerce_subscriptions_product_price_string', 'wc_subscriptions_custom_price_string' );
add_filter( 'woocommerce_subscription_price_string', 'wc_subscriptions_custom_price_string' );

Try this clean code:
/**
* Modify subscription product price string.
*
* #param string $subscription_string Subscription price text.
* #param WC_Product $product WC Product object.
* #return string
*/
function custom_wc_subscriptions_product_price_string( $subscription_string, $product ) {
// If not product then return original string.
if ( ! $product ) {
return $subscription_string;
}
// Get the product id.
$product_id = $product->get_id();
// Define allowed products ids in array comma seperated.
$allowed_products = array( 1001, 1002, 1003 );
// If allowed products is not empty and product is is within allowed products then only run the inner code.
if ( ! empty( $allowed_products ) && in_array( $product_id, $allowed_products, true ) ) {
$subscription_string = sprintf(
/* translators: 1: Sign-up Fee 2: Trail Length 3: Trail Period 4: Subscription Price. */
__( 'Today %1$s, a %2$s %3$s trial of the product, then an outright purchase of %4$s', 'default' ),
wc_price( $product->subscription_sign_up_fee ),
$product->subscription_trial_length,
$product->subscription_trial_period,
wc_price( $product->subscription_price )
);
}
return $subscription_string;
}
add_filter( 'woocommerce_subscriptions_product_price_string', 'custom_wc_subscriptions_product_price_string', 10, 2 );
