To add custom query parameters to pagination links, the ________ configuration option is used.
- custom_params
- page_query_string
- link_params
- query_options
The page_query_string configuration option in CodeIgniter allows the addition of custom query parameters to pagination links, facilitating customization based on specific requirements.
In a scenario where a user logs in through a social media account and their profile picture and bio are automatically updated in the app, this process is known as ________.
- Data Synchronization
- OAuth Integration
- Social Media Scraping
- User Profiling
The correct option is "Data Synchronization." This process involves updating user data in the app in real-time based on changes in the external source, in this case, the social media account. It ensures that the app reflects the latest information from the user's profile.
How does exception handling contribute to a program's robustness?
- Enhances code reliability by handling unexpected errors gracefully
- Increases code complexity and performance issues
- Only applicable in certain programming languages
- Reduces the need for testing
Exception handling improves a program's robustness by allowing it to gracefully handle unexpected errors. It prevents abrupt termination and provides mechanisms to recover or log errors, contributing to overall code reliability.
When integrating a third-party library in CodeIgniter, it is usually placed in which directory?
- application/libraries
- application/third_party
- system/libraries
- system/third_party
When integrating a third-party library in CodeIgniter, it is usually placed in the "application/third_party" directory. This directory serves as a designated location for external libraries that are not part of the CodeIgniter core. Organizing third-party libraries in this directory helps maintain a clean and structured project layout.
During a system upgrade, a developer uses ________ in CodeIgniter to ensure database compatibility with new features.
- controllers
- migrations
- models
- seeds
In CodeIgniter, migrations are used to version control the database schema. During a system upgrade, a developer can create and run migrations to modify the database structure, ensuring compatibility with new features.
In CodeIgniter, the ________ method allows controllers to handle multiple HTTP verbs in a single method.
- _remap
- handleHTTP
- multiHTTP
- requestMethod
In CodeIgniter, the requestMethod method allows controllers to handle multiple HTTP verbs (GET, POST, etc.) in a single method. This is useful for consolidating different actions into a single controller method, improving code organization.
A common issue when integrating third-party libraries in CodeIgniter is __________, which can be resolved by careful version management.
- Class Overloading
- Dependency Collision
- Method Overriding
- Namespace Conflict
One common problem is a Dependency Collision, where different libraries or components may rely on conflicting versions of the same dependency. This can be resolved by carefully managing the versions of the libraries and their dependencies.
In CodeIgniter, the setting $config['sess_ ________'] can be used to enable session encryption for added security.
- encrypt_sessions
- encryption
- secure_encrypt
- session_encrypt
The setting $config['sess_encryption'] in CodeIgniter can be used to enable session encryption. When set to on, it encrypts the session data for added security. This is particularly useful when dealing with sensitive information in the session, providing an additional layer of protection against unauthorized access.
What is the concept of 'exception propagation' in error handling?
- Propagation allows an exception to travel up the call stack until it is caught by an appropriate catch block.
- Propagation is a feature in CodeIgniter that automatically logs exceptions.
- Propagation is the process of creating custom exceptions in CodeIgniter.
- Propagation refers to the automatic handling of exceptions by the PHP interpreter.
Exception propagation in CodeIgniter involves allowing an exception to move up the call stack until it encounters a suitable catch block. This mechanism helps in centralized handling of exceptions at higher levels, enhancing code maintainability.
During a penetration test, it's found that a script from an external domain is executing malicious actions. This indicates a potential ________ vulnerability.
- Cross-Origin Resource Sharing (CORS)
- Cross-Site Request Forgery (CSRF)
- Cross-Site Scripting (XSS)
- SQL Injection
The presence of a script from an external domain executing malicious actions suggests a Cross-Site Scripting (XSS) vulnerability, where untrusted data is rendered without proper validation or escaping.
