Context

⛑️ Ticket(s): https://secure.helpscout.net/conversation/3005790586/86637

Summary

✅ Fixed some potential warnings.
✅ Added compatibility for Date and Time (array based field data).

BEFORE (none of the hidden field data was getting populated, and fatal error/warnings):

AFTER (all data populates correctly):

Walkthrough

The update refines how default values are handled in the add_default_values_to_entry method by introducing type checks and proper conversion of array values for entry saving. It also improves safety in the replace_unreplaced_merge_tags method by using a helper function for array access.

Changes

File	Change Summary
gravity-forms/gw-force-default-value.php	Added type check before variable replacement, converted arrays for entry saving, improved array access safety in merge tag replacement.

Learning: When accessing array values in Gravity Forms code, use `rgar($array, $key, $default = '')` instead of isset() checks for cleaner, more idiomatic code. The `rgar()` function handles both checking if the array key exists and retrieving its value.

File: gp-populate-anything/gppa-acf-repeater-mapper.php:78-87
Timestamp: 2025-04-17T02:43:14.227Z
Learning: When working with Gravity Forms, `rgar()` is a utility function that safely retrieves values from arrays and can be used to implement cleaner safety checks compared to direct conditionals.

gravity-forms/gw-force-default-value.php (4)

83-83: LGTM! Good defensive programming practice.

The type check ensures GFCommon::replace_variables is only called on string values, preventing potential errors when handling array-based field data like Date and Time fields.

---

87-90: Excellent fix for array-based field handling.

This properly addresses the core issue with Date and Time fields by converting array values to a savable entry format using get_value_save_entry(). This ensures compatibility with fields that return array-based data structures.

---

116-116: Good use of Gravity Forms best practices.

Using rgar() instead of direct array indexing provides safer array access and prevents potential undefined index notices. This aligns with the retrieved learnings that recommend using rgar() for cleaner, more idiomatic Gravity Forms code.

---

83-90: Well-executed fix that addresses the core issues.

The changes collectively improve the snippet's robustness by:

• Adding type safety for string operations
• Properly handling array-based field data
• Following Gravity Forms best practices with rgar()

This should resolve the warnings and errors mentioned in the PR objectives while maintaining backward compatibility.

Also applies to: 116-116
