20-20: Consider adding parameter validation.While the current implementation works well, adding basic parameter validation could improve robustness, especially for edge cases like empty arrays or invalid field objects.
Consider adding validation at the beginning of the function:
function arrange_fields_by_page( $fields_backup, $filtered_fields ) { + if ( empty( $fields_backup ) || empty( $filtered_fields ) ) { + return $filtered_fields; + } + $filtered_map = array();
74-74: Consider adding parameter validation.Similar to the previous function, adding validation could enhance robustness.
Consider adding validation:
function randomize_fields_within_pages( $fields ) { + if ( empty( $fields ) ) { + return $fields; + } + $result = array();

Learning: In Gravity Forms snippets, use 'gravityforms' as the translation domain for internationalization functions instead of creating custom domains, to maintain consistency with the related plugin.

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.

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.

1-9: LGTM! Well-documented snippet header.The header provides clear documentation with proper links to documentation and video demonstration. The purpose is clearly stated.
10-18: Filter hook implementation is correct.The hook properly utilizes the
gpr_filtered_fieldsfilter with the correct signature and parameters. The conditional logic appropriately handles both initial display and redisplay scenarios.
20-44: Efficient field mapping and reconstruction logic.The function creates an efficient O(1) lookup map for filtered fields and properly reconstructs the field order while preserving the original page structure. The two-pass approach ensures all fields are included while maintaining proper positioning.
45-72: Excellent cleanup logic for page breaks.The cleanup section effectively handles edge cases:
- Removes consecutive page breaks to prevent empty pages
- Eliminates leading page breaks (forms shouldn't start with a page break)
- Removes trailing page breaks (forms shouldn't end with a page break)
This ensures a clean, functional page structure.
74-97: Solid randomization implementation.The function correctly groups fields between page breaks, shuffles each group independently, and preserves page breaks as separators. The handling of the final group ensures no fields are lost in the randomization process.

23-75: Consider performance optimization for large forms.The function correctly handles field arrangement and page cleanup, but uses multiple array iterations that could impact performance on forms with many fields.
Consider this more efficient approach that combines operations:
function arrange_fields_by_page( $fields_backup, $filtered_fields ) { - $filtered_map = array(); - foreach ( $filtered_fields as $field ) { - $filtered_map[ $field->id ] = $field; - } + $filtered_map = array_column( $filtered_fields, null, 'id' ); $result = array(); $used_ids = array();

🛠️ Refactor suggestion
Consider function naming conflicts in global scope.
The helper functions are defined in global scope which could cause naming conflicts with other plugins or themes.
Wrap the functions in a namespace or use unique prefixes:
-function arrange_fields_by_page( $fields_backup, $filtered_fields ) {
+function gpr_arrange_fields_by_page( $fields_backup, $filtered_fields ) {
// ... function body ...
}
-function randomize_fields_within_pages( $fields ) {
+function gpr_randomize_fields_within_pages( $fields ) {
// ... function body ...
}And update the function calls in the filter hook:
if ( ! $settings['display_count'] ) {
- $filtered_fields = randomize_fields_within_pages( $form['fields'] );
+ $filtered_fields = gpr_randomize_fields_within_pages( $form['fields'] );
} else {
- $filtered_fields = arrange_fields_by_page( $form['fields'], $filtered_fields );
+ $filtered_fields = gpr_arrange_fields_by_page( $form['fields'], $filtered_fields );

In gp-randomizer/gpr-randomize-fields-to-its-own-page.php from lines 23 to 100,
the functions arrange_fields_by_page and randomize_fields_within_pages are
defined in the global scope, risking naming conflicts with other plugins or
themes. To fix this, wrap these functions inside a unique namespace or add a
unique prefix to their names to avoid collisions. Also, update any calls to
these functions accordingly, such as in filter hooks, to use the new namespaced
or prefixed versions.

Add error handling for plugin dependency.
The filter hook logic is sound, but there's no validation that the required gp_randomizer() plugin function exists, which could cause fatal errors if the plugin is deactivated.
Apply this diff to add proper error handling:
add_filter( 'gpr_filtered_fields', function( $filtered_fields, $form ) {
+ if ( ! function_exists( 'gp_randomizer' ) || ! gp_randomizer() ) {
+ return $filtered_fields;
+ }
$feed_id = gp_randomizer()->get_default_feed_id( $form['id'] );
$settings = rgar( gp_randomizer()->get_feed( $feed_id ), 'meta', array() );🤖 Prompt for AI Agents
In gp-randomizer/gpr-randomize-fields-to-its-own-page.php around lines 10 to 21,
the code calls the gp_randomizer() function without checking if it exists, which
can cause fatal errors if the plugin is deactivated. Add a conditional check at
the start of the filter callback to verify if the gp_randomizer() function
exists; if it does not, return the original $filtered_fields immediately to
prevent errors. This ensures safe execution even when the plugin dependency is
missing.
