Blueprints

Blueprints are a key component of the content modeling process. Inside a blueprint you define your fields, which field types they'll implement, group them into sections if you desire, and define conditions controlling their visibility. The control panel uses blueprints to render publish forms so you can manage content.

Overview

Think of blueprints as stencils for your content. They control what fields users get to work with when publishing content, as well as the schema of the data developers will be tapping into to build the front-end of your site.

Each blueprint belongs to an item:

  • You can define multiple Blueprints for collections, and each entry will have the opportunity to choose from one of them.
  • Same goes for taxonomies and their terms.
  • Global sets, Asset containers, and Forms each get their own Blueprint.
  • Users all share a Blueprint.

Creating Blueprints

There are 3 ways to create blueprints:

  • In the respective areas of the control panel. For instance, the collections area will let you define its blueprints.
    The forms area will let you define its blueprints, and so on.
  • In the Blueprints area of the control panel. This page serves as a hub to jump over to managing blueprints in various areas.
  • Creating a YAML file in the appropriate place within resources/blueprints/. More on that in a moment.

Once created, you can begin to define fields and the sections that hold them. If you have more than one section, each becomes a tab in the publish form.

Directory Structure

Whether you manually create your blueprint's YAML file, or use the control panel, they will all end up as YAML files in the resources/blueprints directory.

Statamic Blueprints Folder Structure
Here's how Blueprints are organized in the filesystem.
resources/
blueprints/
collections/
blog/
basic_post.yaml
art_directed_post.yaml
taxonomies/
tags/
tag.yaml
globals/
global.yaml
company.yaml
assets/
main.yaml
forms/
contact.yaml
user.yaml

Collections and Taxonomies have their available blueprints organized in subdirectories named after their collections.
When you create an entry or term, you will be able to choose which blueprint to use (if there are multiple).

Globals, Asset Containers, and Forms can only have one blueprint per item, so they are organized into their own subdirectories, where each YAML file is the handle of the item.

All users will share the same blueprint, and it hangs out in the root of the directory.

Conditional Fields

It’s possible to have fields be displayed only under certain conditions. For example, you may only want to show a caption field if an asset field has an image selected, or a whole block of fields if a toggle switch is enabled.

YAML Structure

At its most basic, a blueprint has an array of sections.

sections: []

A section has a handle, a display name, and an array of fields:

sections:
main:
display: Main
fields:
-
handle: content
type: markdown
meta:
display: SEO Metadata
fields:
-
handle: meta_title
type: text
-
handle: meta_description
type: textarea
Hot Tip!

Blueprint fields are indexed sequentially instead of keyed by handle. This format allows maximum flexibility: you can reference fields from other blueprints one or more times, override their settings inline, and even reference existing fields for Bard, Replicator, and Grid sets.

Reusable Fields

A section's fields can be comprised of references to fields in fieldsets (so you can reuse fields) or inline field definitions.

Field References

You will likely want to pre-configure reusable fields to pull into your blueprints.

For example, you might have a rich text field configured with all your favorite buttons, which you've called content and stored in the common fieldset.

You can pull it into your blueprint like so:

fields:
-
handle: my_content_field
field: common.content
-
handle: another_content_field
field: common.content

This way, you are free to reuse the same field as many times as you like. Update the field in the fieldset and it will be reflected across all your blueprints.

Customizing Fields

You may customize a referenced field by adding a config array. Any keys found in this will override whatever was defined in your fieldset.

fields:
-
handle: my_content_field
field: common.content
config:
display: My Content Field
validate: required|max:200

Here, the display and validate would replace whatever was defined in the fieldset.

Note: This only applies to referenced fields. For inline fields, you can just set everything right there.

Importing Fieldsets

Fieldsets still exist in Statamic 3! They serve to create reusable sets of fields, just like v2. You may import an entire fieldset at any point by using the import key, for example:

# blueprint
 
fields:
-
import: survey
prefix: favorite_
-
import: survey
prefix: least_favorite_
# the survey.yaml fieldset
 
fields:
-
handle: food
type: text
-
handle: food_reason
type: textarea

Doing the above would result in a blueprint like this:

fields:
-
handle: favorite_food
field:
type: text
-
handle: favorite_food_reason
field:
type: textarea
-
handle: least_favorite_food
field:
type: text
-
handle: least_favorite_food_reason
field:
type: textarea

It would bring every field inline and prefix each field's handle appropriately.

If you omit the prefix you won't be able to import them more than once at the same level because they would have the same handle and overwrite each other.

Validation

Fields can have various validation rules applied to them, enforcing the need for content creators to fill them out in a specific way before saving or publishing.

While configuring a field, switch to the Validation tab where you can choose from any built in Laravel rule.

Field validation
Add validation rules (with a shortcut for requiring)

In this screenshot, you can see that the field has an alpha_dash and min:4 rule which means you can only type letters and dashes, like a slug, and that it
must be at least 4 characters. You have plenty of options to be creative and confident that your data will be entered the way you need it to be.

Here's a peek at how that YAML is structured.

-
handle: your_field
field:
type: text
validation:
- alpha_dash
- 'min:4'

Required Fields

Being the most common type of validation rule, we give you a shortcut for that. Simply toggle it on, or add required: true to the YAML.

Grid Fieldtype

The Grid fieldtype lets you define a set of sub-fields, which it will allow you to repeat as many times as you like.

You should define its fields using the blueprint field syntax. This will allow you to reference other fields and/or import entire fieldsets.

An example grid field
This is an example Grid field.
links:
type: grid
fields:
-
handle: url
field: links.url
-
handle: text
field: links.text
-
handle: external
field: links.external

Unlisted Fields

While conditional fields allow you to control field visibility on the publish form, you may also customize column visibility on entry listings in the control panel.

listable: false

This hides the field column from entry listings, which can be useful for toggle fields etc, which may never make sense in the context of an entry listing.

listable: hidden

This will hide the field from entry listings by default, but still allows a user to toggle visibility using the column selector, and save those column preferences for his/her preferred workflow.
