If wallet balance < than order total then redirect to Top Up

Oh! I forgot to mention, at the moment I am using a temporary fix, so if the customer hasn´t got enough money in the wallet, he will be prompted with a wallet top up form on the last step of the checkout, as you can see here:

This is not optimal, as they will have to fill all the fields just to find out they have to do a top up…. but it may help somebody out there, so to achiveve this go to woocomerce/templates/checkout/payment.php and on line 32(at list in my file) you will find:

else {
				echo '<li class="woocommerce-notice woocommerce-notice--info woocommerce-info">' . apply_filters( 'woocommerce_no_available_payment_methods_message', WC()->customer->get_billing_country() ? esc_html__( 'Sorry, it seems that there are no available payment methods for your state. Please contact us if you require assistance or wish to make alternate arrangements.', 'woocommerce' ) : esc_html__( 'Please fill in your details above to see available payment methods.', 'woocommerce' ) ) . '</li>'; // @codingStandardsIgnoreLine
			}

Well inside that else statement and under the echo just paste this:

<form method="post" action="">
			<div class="woo-wallet-add-amount">
				<?php
				$min_amount = woo_wallet()->settings_api->get_option( 'min_topup_amount', '_wallet_settings_general', 0 );
				$max_amount = woo_wallet()->settings_api->get_option( 'max_topup_amount', '_wallet_settings_general', '' );
				?>
				<p>
					<input type="number" style="max-width: 70%;" step="0.01" min="<?php echo esc_attr( $min_amount ); ?>" max="<?php echo esc_attr( $max_amount ); ?>" name="woo_wallet_balance_to_add" id="woo_wallet_balance_to_add" class="woo-wallet-balance-to-add input-text" placeholder="<?php esc_attr_e( 'Enter amount', 'woo-wallet' ); ?>" required="" />
					<input type="submit" class="button" value="<?php esc_attr_e( 'Add', 'woo-wallet' ); ?>" />
				</p>
				<?php wp_nonce_field( 'woo_wallet_topup', 'woo_wallet_topup' ); ?>
	</div>
</form>

Hi @poll0none You can use the attached code in the theme functions.php file to redirect the user to the wallet top-up page from the checkout page if there is not enough wallet balance.

add_action('template_redirect', 'redirect_if_no_wallet_balance');
if(!function_exists('redirect_if_no_wallet_balance')){
	function redirect_if_no_wallet_balance(){
		if(is_checkout()){
			if( wc()->cart->get_total('edit') > woo_wallet()->wallet->get_wallet_balance(get_current_user_id(), 'edit') ){
				wp_safe_redirect( wc_get_endpoint_url( get_option( 'woocommerce_woo_wallet_endpoint', 'woo-wallet' ), 'add', wc_get_page_permalink( 'myaccount' ) ) );
			}
		}
	}
}
