User fields are added to the WPGraphQL Schema as a field with a User type.
Here, we have a User field named user on the Post Edit screen within the "ACF Docs" Field Group, set with the User "jasonbahl" as the value.
This field can be queried in GraphQL like so:
{
post(id: "acf-example-test", idType: URI) {
acfDocs {
user {
id
username
firstName
lastName
}
}
}
}and the response would look like:
{
"data": {
"post": {
"acfDocs": {
"user": {
"id": "dXNlcjox",
"username": "jasonbahl",
"firstName": "Jason",
"lastName": "Bahl"
}
}
}
}
}If the field is configured to allow multiple selections, it's added to the Schema as a List Of the User type.
Here, we have a User field named user on the Post Edit screen within the "ACF Docs" Field Group, set with the User "jasonbahl" and "WPGraphQL" as the value.
and the response to the same query would look like:
{
"data": {
"post": {
"acfDocs": {
"user": [
{
"id": "dXNlcjox",
"username": "jasonbahl",
"firstName": "Jason",
"lastName": "Bahl"
},
{
"id": "dXNlcjoy",
"username": "WPGraphQL",
"firstName": "WP",
"lastName": "GraphQL"
}
]
}
}
}
}
