How do I go about using a dynamic value to access a user field value? I have created a form builder for users and dynamically populate the user field based on the question's associated field.

<input name="fields[{{ question.fieldName }}]">

This works nicely but I am looking to pre-populate this input with a value if the user has previously provided and saved this info but I'm having trouble figuring out how to combine the field name with currentUser.

My first try was:

{% set fieldName = question.fieldName %}
{{ currentUser.fieldName }}

But that returns the following error:

Craft\UserModel and its behaviors do not have a method or closure named "fieldName".

Any help would be greatly appreciated

You could try using the attribute function in twig, this should let you call dynamic properties.

Something like:

{{ attribute(currentUser, question.fieldName) }}
  • Thanks for the suggestion, I tested it but get returned the following error: array_key_exists(): The first argument should be either a string or an integer Commented Apr 12, 2017 at 15:16
  • What values are you getting if you dump question.fieldName? Commented Apr 12, 2017 at 15:19
  • Sorry, using the attribute function did work. I just needed to to adjust it to use question.fieldName.value so I set that as a variable as such: {% set questionField = category.fieldName.value %} {{ attribute(currentUser, questionField ) }} Thanks! Commented Apr 12, 2017 at 18:54
