Field Item Relationship

A Statamic plugin that adds a Field Item Relationship fieldtype.
With Field Item Relationship you can select a value from a source fields' items. That source field could be a sibling or ancestor field (in the same blueprint), or come from a Global set.

Installation

Install this plugin using composer.

composer require eminos/statamic-field-item-relationship

Features

• The source field could be a sibling or ancestor field, or come from a Global set.
• Set which key/field should be used as the select option label.
• Use string literal for advanced option label configuration (see screenshot #4)
• Choose what you want to save as the selected item.
  • Key/Index
  • Specified object key
  • Full item/object
• Comes with a Tag {{ fir }} to help you fetch the selected source field item.

Field configuration

The field configuration will depend on the source field data type.
Depending on if the source data is a simple array of strings, an array of objects or an individual object, different "Save as" options will be possible.

You will get a warning message in the field if the field configuration isn't compatible with the source field data.

Tag usage

This fetches the source value from the configured source field in field "field_item_relationship_field".

{{ fir:field_item_relationship_field }}

If the source value is an object you get its values like this.

{{ fir:field_item_relationship_field }}
    {{ text_field_1 }}
    {{ some_other_field }}
{{ /fir:field_item_relationship_field }}

Or by specifying the target field in the tag like this:

{{ fir:field_item_relationship_field:text_field_1 }}

Even nested fields work, like this:

{{ fir:field_item_relationship_field:some_field.child_field }}

You can also get Global fields:

{{ fir:global_set:field_item_relationship_field:nested.target.path }}

An other way is to use the field and path parameters:

{{ fir field="global_set:field_item_relationship_field" path="some_field.child_field" }}
