Posts

These are examples of queries to fetch and modify post data.

Fetching posts

A single post, with author and tags:

query {
  post(by: { id: 1 }) {
    title
    content
    url
    date
    author {
      id
      name
    }
    tags {
      id
      name
    }
  }
}

A list of 5 posts with their comments:

query {
  posts(pagination: { limit: 5 }) {
    id
    title
    excerpt
    url
    dateStr(format: "d/m/Y")
    comments(pagination: { limit: 5 }) {
      id
      date
      content
    }
  }
}

A list of predefined posts:

query {
  posts(filter: { ids: [1499, 1657] }) {
    id
    title
    excerpt
    url
    date
  }
}

Filtering posts:

query {
  posts(
    filter: { search: "wordpress", dateQuery: { after: "2019-06-01" } },
    sort: { order: ASC, by: TITLE }
  ) {
    id
    title
    excerpt
    url
    status
  }
}

Counting post results:

query {
  postCount(
    filter: { search: "api" }
  )
}

Paginating posts:

query {
  posts(
    pagination: {
      limit: 5,
      offset: 5
    }
  ) {
    id
    title
  }
}

Posts with tags:

query {
  posts(
    filter: { tagSlugs: ["graphql", "wordpress", "plugin"] }
  ) {
    id
    title
  }
}

Posts with categories:

query {
  posts(
    filter: { categoryIDs: [50, 190] }
  ) {
    id
    title
  }
}

Fetching meta values:

query {
  posts {
    title
    metaValue(
      key: "_wp_page_template",
    )
  }
}

Fetching the logged-in user's posts

Fields post, posts and postCount only retrieve posts with status "publish".

To fetch posts from the logged-in user, with any status ("publish", "pending", "draft" or "trash"), use these fields:

  • myPost
  • myPosts
  • myPostCount
query {
  myPosts(filter: { status: [draft, pending] }) {
    id
    title
    status
  }
}

Creating posts

Only logged-in users can create posts.

mutation {
  createPost(
    input: {
      title: "Hi there!"
      contentAs: { html: "How do you like it?" }
      status: draft
      tags: ["demo", "plugin"]
    }
  ) {
    status
    errors {
      __typename
      ...on ErrorPayload {
        message
      }
      ...on GenericErrorPayload {
        code
      }
    }
    postID
    post {
      status
      title
      content
      url
      date
      author {
        id
        name
      }
      tags {
        id
        name
      }
    }
  }
}

Updating posts

Only users with the corresponding capabilities can edit posts.

mutation {
  updatePost(
    input: {
      id: 1,
      title: "This is my new title",
    }
  ) {
    status
    errors {
      __typename
      ...on ErrorPayload {
        message
      }
      ...on GenericErrorPayload {
        code
      }
    }
    post {
      id
      title
    }
  }
}

This query uses nested mutations to update the post:

mutation {
  post(by: { id: 1 }) {
    originalTitle: title
    update(input: {
      title: "This is my new title",
      contentAs: { html: "This rocks!" }
    }) {
      status
      errors {
        __typename
        ...on ErrorPayload {
          message
        }
      }
      post {
        newTitle: title
        content
      }
    }
  }
}
