How to create dependent Fields in the Content Page.

By Neeraj420 on 7 Feb 2018 at 14:56 UTC

I have created a Taxonomy Vocabulary and terms within those Vocabulary as below.

Vocabulary1

-- Term1

-- Term2

Vocabulary2

-- Term3

-- Term4

I have created two fields

field1

field2

Field1 contains list of all the vocabulary. and Fields2 should contains of terms with reference Vocabulary selected in field1. Lets say Vocabulary1 is selected in Field1 then field2 should display term1 and term2. if vocabulary2 is selected field2 should contain the terms3 and term4.

I came across one article at https://www.drupal.org/docs/8/modules/business-rules/advanced-usage/depe... it gave a different approach to implement in different way using business rules. However I am getting following error when I implemented this.

[Wed Feb 07 19:48:20.069448 2018] [php7:notice] [pid 8356:tid 1340] [client ::1:52662] Uncaught PHP Exception InvalidArgumentException: "Field is unknown." at D:\\VPSite\\journals\\core\\lib\\Drupal\\Core\\Entity\\ContentEntityBase.php line 509, referer: http://localhost/journals/node/add

when creating a content, having these fields.

Please help, in case I am missing some thing or if this is a bug in using the business rules please share how do i achieve this.

Thanks in advance.

Have you tried Conditional

Have you tried Conditional Fields ? I've never used it to check the condition of a selected term but give it a go.

Yes Conditional Field module

Yes Conditional Field module is working fine as expected. the only hitch was, I was not able to find any documentation. So took time to get used to it.

Thanks for your help Ivan
