Check all child entries don't exceed total field on parent form

This code snippet ensures that the sum of all child entries in a Gravity Forms nested form does not exceed the total specified in the parent form. It validates the "Amount" field in child entries against the "Total" field in the parent form, preventing over-allocation of resources, budgets, or quotas.

Features

  • Validates child form entries to ensure the cumulative amount does not exceed the total in the parent form.
  • Works with Gravity Forms Nested Forms to enforce limits across multiple child entries.
  • Dynamically calculates totals from submitted child entries.
  • Customizable field labels (e.g., "Amount" in child forms and "Total" in the parent form).
  • Displays a validation message when the limit is exceeded, preventing submission errors.
