Aangepaste afrekenvelden

Het toevoegen van aangepaste velden aan het afrekenformulier is eenvoudig te doen met slechts een paar functies. De onderstaande code stelt u in staat om twee extra velden toe te voegen, één voor Telefoon en één voor Bedrijf.

Let op: we hebben ingebouwde instellingen om afrekenadresvelden aan te passen en ze naar wens te rangschikken. Als alternatief hebben we ook een officiële extensie waarmee u aangepaste afrekenvelden kunt maken. Bekijk de Checkout Fields Manager extensie.

De onderstaande code voegt een veld voor telefoonnummer toe aan het afrekenformulier.

/**
 * Adding a custom field to the checkout screen

 * Adding a phone number field to the checkout
 * Making the phone number field required
 * Setting an error when the phone number field is not filled out
 * Storing the phone number into the payment meta
 * Adding the customer's phone number to the "view order details" screen
 * Adding a new {phone} email tag so you can display the phone number in the email notifications (standard purchase receipt or admin notification)
