Capitalize Specific Field Value Before Saving Entry – Code Snippet Directory

GOAL

By default this code snippet automatically converts the value of a specific text field to uppercase before saving the entry in Gravity Forms. It ensures consistency in formatting and is particularly useful for fields like names, codes, or identifiers that require capitalization. Now also allows numerous other text manipulations and transformations:

•  Case transformations: uppercase, lowercase, title case, camelCase, PascalCase, sentence case
• Formatting: URL-friendly slugs, phone number formatting, whitespace trimming, space collapsing
• Cleaning: strip HTML tags, remove non-alphanumeric characters
• Special: string reversal

Features

• Ensures uniform formatting for data consistency.
• Applies only to text input fields, preventing unintended changes to other field types.
• Easily customizable by modifying the form and field ID in the filter hook.
• Multiple transformations can be applied in sequence
• Highly configurable with 12+ built-in transformation options
• Preserves original value if transformation not applicable
• Sanitizes output for security

CONFIGURATION REQUIRED

• gform_save_field_value_3_16: Change '3' to your target form ID (or remove '_3' to apply to all forms)
• gform_save_field_value_3_16: Change '16' to your target field ID (or remove '_16' to apply to all fields on the form)
• $apply: Default is set to uppercase ('upper'). Other options include: 'lower', 'title', 'camel', 'pascal', 'sentence', 'slug', 'trim', 'collapse', 'alphanumeric', 'phone', 'strip_tags', 'reverse'. Add or modify transformations as needed.
