BrightLeaf Digital Code Snippet Library

This code snippet enforces validation on a Gravity Forms Nested Form field, ensuring that at least one child entry in a batch contains a specific value in a selected field. If no child entry meets the requirement, the form submission is blocked, and a validation message is displayed.

Remember to configure the array at the top of the snippet. Change the 71 to the id of the parent form. Then replace the nested_field_id with the id the nested form has on the parent form. The child_field_id should be replaced with the field that has a required value and required_value should be replaced with the required value.

Features

• Ensures at least one child entry contains a required value before submission.
• Works with Gravity Forms Nested Forms, validating child form entries within a parent form.
• Customizable per form, allowing different field and value requirements for multiple forms.
• Prevents incorrect submissions by enforcing specific data conditions.
• Displays a validation message if no child entry meets the required criteria.
• Lightweight and efficient, checking only relevant forms and fields.
