netSEO Input field for CS-Cart - Product Options Module with Placeholder and Maximum Length

netSEO: Input field for CS-Cart

netSEO: Input field is a professional addon for CS-Cart that extends product options with a dedicated text field type, offering placeholder support and configurable maximum length. The module allows creating options such as "Empty text field", "Attachment", "Custom text" or any other input field, with clear guidance for the customer and automatic validation when adding to cart.

EXAMPLE:

Dedicated option type "Input field"

The module adds a new option type to the product options list:

• It appears in the admin as "Input field" (or "Input field" in English)
• Identical behavior to the standard text field, with additional settings
• The value entered by the customer is saved in the cart and in the order.
• Compatible with simple and variant products

Placeholder (guide text in the field)

Administrators can set a placeholder for each option:

• Text displayed in the field when empty (HTML5 placeholder attribute)
• Clear guidance for the customer (e.g. "example.com", "Enter the name")
• Reduce errors and customer questions
• Optional – the field can be left blank if it is not required

Maximum length configurable

Each "Input Field" option can have a maximum length:

• Maximum number of characters allowed (ex: 50, 100, 255)
• Value 0 = no limit
• Automatic validation when adding to cart – the customer is notified if they exceed the limit
• Protection against entering too long text

Validation when adding to cart

The module correctly validates the options when adding the product to the cart:

• Required options – the customer must complete the field
• Maximum length respected – clear error message with option name and limit
• Translatable error messages (Romanian/English)
• Improved user experience, no commands with invalid data

Configuration in administration

When editing product options (Products → Options or options per product), the administrator can:

• Select the "Input Field" type from the option type dropdown
• Fill in the placeholder (customer guide text)
• Set maximum length (0 = no limit)
• Use standard CS-Cart options: mandatory, position, etc.

Save and display in cart and order

The values entered by the customer are persisted correctly:

• Save to cart at "Add to Cart"
• Save to order upon completion
• Visible in order details in admin and in emails
• No changes to the standard CS-Cart structure – the type is stored as a standard input with additional data in a dedicated table

Compatibility and performance

The addon is built for stability and compatibility:

• Compatible with CS-Cart 4.14.0+, ULTIMATE and MULTIVENDOR editions
• Doesn't change existing options – just adds a new type
• Delete option also deletes additional data (placeholder, max_length)
• Cache cleared on install/uninstall

Native integration into CS-Cart

netSEO: Input field integrates perfectly into the administration interface and the store's frontend: the new type appears in the list of option types, and on the product page the customer sees the text field with placeholder and character limit, just like a native field.

Without a dedicated option type with placeholder and maximum length, implementing fields like "Domain" or "Custom Text" requires workarounds or code changes. This addon provides the complete solution, easy to configure, with automatic validation and optimal customer experience, ideal for software licenses, customizations or any text-based option with clear requirements.
