dict_has_key

The dict_has_key function checks whether a dictionary contains a specific key.

Syntax

{{ dict_has_key dictionary "key" }}

Example

{{ $data := dict_create "title" "Hello World" "author" "Alice" }}

{{ if dict_has_key $data "title" }}
  <h1>{{ dict_get $data "title" }}</h1>
{{ end }}

{{ if dict_has_key $data "subtitle" }}
  <h2>{{ dict_get $data "subtitle" }}</h2>
{{ else }}
  <h2>No subtitle</h2>
{{ end }}

Output:

  <h1>Hello World</h1>

  <h2>No subtitle</h2>

Notes

• Returns true if the key exists, false otherwise
• Useful for conditional rendering based on data availability
• The key's value doesn't matter—even empty string or false values return true if the key exists
