A plugin for [Payload CMS](https://github.com/payloadcms/payload) to easily allow your admin editors to build and manage forms from the admin panel.

Core features:
- Creates a `forms` collection where you can:
- Build dynamic forms with any number of fields
- Add payment fields that can handle dynamic prices
- Build completely custom and dynamic emails
- Creates a `formSubmissions` collection that:
- Validates and saves the form data submitted by your frontend
- Sends emails (if applicable)
- Handles payment processing (if applicable)

### Options

- `fields`
An object of field types to allow your admin editors to build forms with. Pass either a boolean value or a partial [Payload Block](https://payloadcms.com/docs/fields/blocks#block-configs) to override default settings. See [Fields](#fields) for more details.

```js
fields: {
text: true,
textarea: true,
select: true,
email: true,
state: true,
country: true,
checkbox: true,
number: true,
message: true,
payment: false
}
```

You can also provide your own custom field definitions by passing a new [Payload Block](https://payloadcms.com/docs/fields/blocks#block-configs) object into `fields`.

- `redirectRelationships`

An array of collection slugs that, when enabled, are populated as options in form redirect fields.

```js
redirectRelationships: ['pages']
```
```js

```

- `handlePayment`

A [beforeChange]([beforeChange](https://payloadcms.com/docs/hooks/globals#beforechange)) hook that is called upon form submissions. You can integrate into any third-party payment processing API here. There is a `getPaymentTotal` function that will calculate the total cost after all conditions have been applied.

```js
import { getPaymentTotal } from '@payloadcms/plugin-form-builder';
...
handlePayment: async ({ form, submissionData }) => {
// first calculate the price
const paymentField = form.fields?.find((field) => field.blockType === 'payment');
const price = getPaymentTotal({
basePrice: paymentField.basePrice,
priceConditions: paymentField.priceConditions,
fieldValues: submissionData,
});
// then asynchronously process the payment here
}

- `formOverrides`
Override anything on the form collection by sending a [Payload Collection Config](https://payloadcms.com/docs/configuration/collections). Your overrides will be merged into the default `forms` collection.

slug: "contact-forms";

```
- `formSubmissionOverrides`
By default, this plugin relies on [Payload access control](https://payloadcms.com/docs/access-control/collections) to restrict the `update` and `read` operations. This is because anyone should be able to create a form submission, even from a public-facing website - but no one should be able to update a submission one it has been created, or read a submission unless they have permission.

## Troubleshooting
Below are some common troubleshooting tips. To help other developers, please contribute to this section as you troubleshoot your own application.
### SendGrid 403 Forbidden Error
- If you are using [SendGrid Link Branding](https://docs.sendgrid.com/ui/account-and-settings/how-to-set-up-link-branding) to remove the "via sendgrid.net" part of your email, you must also setup [Domain Authentication](https://docs.sendgrid.com/ui/account-and-settings/how-to-set-up-domain-authentication). This means you can only send emails from an address on this domain — so the `from` addresses in your form submission emails **_cannot_** be anything other than `something@your_domain.com`. This means that from `{{email}}` will not work, but `website@your_domain.com` will. You can still send the form's email address in the body of the email.
