Hi Mirko,
I solved all the requirements.
Thanks.
I will put here some code to show how I’ve done it

//setting up global obj
$stripe_meta_obj = (object) [
    "donation_fee" => 0,
    "donation_fee_percentage" => 0,
	"donation_subtotal" => 0,
	"donation_total"=>0
];

add_filter( 'woocommerce_order_button_html', 'custom_button_html' );

function custom_button_html( $button_html ) {
	$button_html = str_replace( 'Back Campaign Now', 'Donate', $button_html );
	return $button_html;
}
//$donation_fee = 5;
function try_update_cart_form() {
	if( is_page( array( 'checkout' ) ) ){
		
	
	$get_prod_id;
	$get_prod_price;	
	foreach( WC()->cart->get_cart() as $cart_item ){
    	$get_prod_id = $cart_item['product_id'];
		$get_prod_price = $cart_item['line_total'];
	}
?>
<script type="text/javascript">
	jQuery( document ).ready(function($) {
		jQuery('#donation_amount').attr({"type":"number", "min" : 1, "step":1});
		jQuery('#donation_amount_field .woocommerce-input-wrapper').prepend('<span class="currency_symbol"><?php echo get_woocommerce_currency_symbol(); ?></span>');
		//echo get_woocommerce_currency_symbol();
		
					var typingTimer;                //timer identifier
					var doneTypingInterval = 100;  //time in ms, 5 second for example
					var $input = jQuery('#donation_amount');
					$input.val(<?php echo esc_attr($get_prod_price); ?>);
					//on keyup, start the countdown
					$input.on('keyup', function () {
						
					clearTimeout(typingTimer);
						typingTimer = setTimeout(doneTyping, doneTypingInterval);
					});

					//on keydown, clear the countdown 
					$input.on('keydown', function () {
					clearTimeout(typingTimer);
					});

					//user is "finished typing," do something
					function doneTyping () {
					//do something

						let data = {

	jQuery('#anonymous_checkout_field #anonymous').change(function() {

</script>
<?php

}
add_action( 'wp_footer', 'try_update_cart_form' );

add_action( 'woocommerce_cart_calculate_fees', 'woo_add_cart_fee' );
function woo_add_cart_fee( $cart ){
	 global $stripe_meta_obj;
	
     if ( ! $_POST || ( is_admin() && ! is_ajax() ) ) {
        return;
    }
	
    if ( isset( $_POST['post_data'] ) ) {
        parse_str( $_POST['post_data'], $post_data );
    } else {
        $post_data = $_POST; // fallback for final checkout (non-ajax)
    }
	
	

    if (isset($post_data['application_fee_amount'])) {
		function getPercentOfNumber($number, $percent){
    		return ($percent / 100) * $number;

        $donation_fee_amount = $post_data['application_fee_amount'];

}

I’m using snippets and woocommerce checkout form
And for the message after payment andstripe metadata

function add_condolences($order_id){
	function IsNullOrEmptyString($str){
    return (!isset($str) || trim($str) === '');
}

	
	foreach( WC()->cart->get_cart() as $cart_item ){
    	$product_id = $cart_item['product_id'];
		$condolance_message = WC()->checkout->get_value('message');
		
		
		

		if($condolance_message){
				$comment_id = wp_insert_comment( array(
				'comment_post_ID'      => $product_id, // <=== The product ID where the review will show up
				'comment_author'       => WC()->checkout->get_value( 'anonymous' ) ? "Anonymous" : WC()->checkout->get_value( 'billing_first_name' ) . " " . WC()->checkout->get_value( 'billing_last_name' ),
				'comment_author_email' => WC()->checkout->get_value( 'anonymous' ) ? WC()->checkout->get_value('billing_email') : " ", // <== Important
				'comment_author_url'   => '',
				'comment_content'      => $condolance_message,
				'comment_type'         => '',
				'comment_parent'       => 0,
				'user_id'              => 0, // <== Important
				'comment_author_IP'    => '',
				'comment_agent'        => '',
				'comment_date'         => date('Y-m-d H:i:s'),
				'comment_approved'     => 1,
			) );
			update_comment_meta( $comment_id, 'rating', 0 );
		}
			
	}
}

//add_action( 'woocommerce_before_checkout_process', 'add_condolences');
add_action( 'woocommerce_payment_complete', 'add_condolences');

function wbdc_filter_wc_stripe_payment_metadata( $metadata, $order, $source ) {
	global $stripe_meta_obj;
	
    $order_data = $order->get_data();
	
	foreach( $order->get_items() as $item_id => $line_item ){
		$product = $line_item->get_product();
		$product_name = $product->get_name();
		$metadata['Campaign Name'] = $product_name;

	$metadata[ __( 'Donation Subtotal', 'woocommerce-gateway-stripe' ) ] = number_format($stripe_meta_obj->donation_subtotal, 2 );
	$metadata[ __( 'Donation Total', 'woocommerce-gateway-stripe' ) ] = number_format($stripe_meta_obj->donation_total, 2 ); 
//var_dump( $string_donation_fee_percentage . "%");

    return $metadata;
//	return false;
}
add_filter( 'wc_stripe_payment_metadata', 'wbdc_filter_wc_stripe_payment_metadata', 10, 3 );

Sorry, I was not explicit. What I meant what that I need to make some changes in single-crowdfunding.php page for example in the design…
The problem is that I cannot see any changes

Thank you,
Emanuel

Hi,
thanks for reply.
That design was to show you what I want to do, but my main problem is that I need a way to intercept checkout submit to update the price, add comment using update_comment_meta( $comment_id, ‘rating’, 1 ); and to send application_fee_amount to stripe for split payment.
I’m a c# developer, I don’t really know what fields do I need to map ??

Thank you,
Emanuel

Removed jQuery 3.6 Version ??

Okay, thank you
