Custom Input is an add-on for the Payment Button for PayPal WordPress plugin (also known as WP PayPal or WordPress PayPal) that can be used to show a text box with the Buy Now buttons. The text box can be used to collect custom data from buyers.
How to Enable Custom Input
Open the product in question (WP PayPal > Products > Edit) and Enable Custom Input in it.
When the button for this product is rendered on the front end (using wp_paypal_product shortcode), a text box will appear with it which lets buyers enter any data (This can be useful if a buyer would like to include a custom note or special instruction).

The default label for the custom input field (Enter any special instructions) can be customized in the add-on settings (WP PayPal > Custom Input).
