What steps should be taken to properly evaluate and send data to PayPal when using a pre-generated Buy Now button in PHP?

To properly evaluate and send data to PayPal when using a pre-generated Buy Now button in PHP, you need to ensure that the necessary information (such as item name, price, currency, etc.) is correctly passed to the PayPal payment URL. This can be achieved by constructing the payment form with hidden input fields containing the required data and submitting it to the PayPal endpoint. 

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
    <input type="hidden" name="cmd" value="_xclick">
    <input type="hidden" name="business" value="your_paypal_email@example.com">
    <input type="hidden" name="item_name" value="Product Name">
    <input type="hidden" name="amount" value="10.00">
    <input type="hidden" name="currency_code" value="USD">
    <input type="hidden" name="return" value="http://example.com/success.php">
    <input type="hidden" name="cancel_return" value="http://example.com/cancel.php">
    <input type="image" src="https://www.paypalobjects.com/en_US/i/btn/btn_buynow_LG.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online">
</form>
