Hash variable is a placeholder used to dynamically display data from various sources within your application. It allows you to insert dynamic content without hardcoding values, making your applications more flexible and customizable.

Key Uses of Hash Variables in Joget:

1. Fetching Form Data:

   • Retrieve and display data from form fields.

     plaintext
     
     #form.formId.fieldId#
     

     Example: #form.myForm.name# gets the value from the "name" field in the form "myForm".

2. Accessing Workflow Variables:

   • Display values from workflow variables.

     plaintext
     
     #variable.variableId#
     

     Example: #variable.requesterName# gets the value of the "requesterName" variable.

3. System Information:

   • Get details like the current date or logged-in user info.

     plaintext
     
     #currentUser.username#
     #date.today#
     

Example Uses:

• Personalized Email Content: Use hash variables to customize automated emails.

  plaintext
  
  Hello #form.requestForm.name#,
  
  Your request submitted on #date.today# has been approved.
  

• Dynamic User Interface: Show different content based on user input or workflow state.

  plaintext
  
  {% if #form.feedback.rating# >= 4 %}
  Thank you for your positive feedback!
  {% else %}
  We're sorry to hear that. Please tell us how we can improve.
  {% endif %}
