Creating Fields: Using the PMProRH_Field class

The PMProRH_Field class has various options for different types of fields, but there is a set of general options which applies to every type.

Fields are added via the PMProRH_Field object with 3 parameters:

• The name attribute. This is the meta key that is used when storing the field value in the wp_usermeta table. The name must only contain letters, numbers, and underscores (no spaces, dashes or special characters).
• The field type.
• An array of options. There are some options that apply to every field type, and some that are unique to specific field types. See below for more details.

Adding Fields: Using the pmprorh_add_registration_field() function

Now that you have created your fields, you need to add the registered fields to the checkout and profile pages. This is done via the pmprorh_add_registration_field() function.

pmprorh_add_registration_field() parameters:

1. the location of the new field
2. the PMProRH_Field object itself

---

By default, you can place a new field in one of 8 different locations:

• after_username
• after_password
• after_email
• after_captcha
• checkout_boxes
• after_billing_fields
• before_submit_button
• just_profile – The field will only be shown on the Edit User/Profile pages. To use this, “profile” must be set to either true or admin.

Checkout Boxes

You can add additional locations for your fields called checkout boxes. Each checkout box is its own <table> element like the Billing Fields or Username Fields sections, and has its own label and description. By default, new checkout boxes are displayed in the order they are added and have the label “More Information”.

To add a new checkout box, use the pmprorh_add_checkout_box function. It takes 4 parameters:

• the ID of the checkout box
• (optional) the label for the checkout box (Default: “More Information”)
• (optional) the description for the checkout box
• (optional) the order of the checkout box

---

Then add fields to these boxes.

Checkout boxes can be reordered by passing an integer for the order.
