To override default controllers, models, or libraries, the developer should place these in the ________ directory.
- application/controllers
- application/custom
- application/extensions
- application/overrides
In CodeIgniter, to override default controllers, models, or libraries, the developer should place these customized versions in the 'application/overrides' directory.
How do SameSite cookies contribute to CSRF protection?
- CSRF is entirely unrelated to SameSite cookies.
- Mitigates CSRF by restricting cookie access based on the request source.
- Prevents CSRF by encrypting cookies to make them inaccessible to attackers.
- SameSite cookies have no impact on CSRF protection.
SameSite cookies contribute to CSRF protection by restricting cookie access based on the request source. This helps prevent malicious requests from other sites that might attempt to perform actions on behalf of the user. It's an additional layer of security to ensure that cookies are only sent in a first-party context, reducing the risk of CSRF attacks.
In CodeIgniter, ________ is a common library used for parsing XML files.
- SimpleXML
- XMLHandler
- XMLParser
- XMLReader
CodeIgniter commonly uses the SimpleXML library for parsing XML files. It provides a simple interface for working with XML data in an object-oriented manner.
To update records in a database using CodeIgniter's Query Builder, the ________ method is used.
- change()
- modify()
- set()
- update()
The correct method to update records in a database using CodeIgniter's Query Builder is the update() method. It allows you to set the values you want to update using the set() method.
Which function in the Active Record Class is used to read data from the database?
- fetch()
- get()
- read()
- select()
The get() function in the Active Record Class is used to read data from the database. It allows you to specify the table and conditions for retrieving data. This method simplifies the process of querying the database and fetching results in a structured manner.
The ________ directory is used for adding custom helper functions in CodeIgniter.
- application/custom
- application/helpers
- application/libs
- application/utilities
CodeIgniter uses the 'application/helpers' directory for adding custom helper functions. Helper functions are sets of utility functions that can be used throughout the application.
In payment gateway integrations, what is the purpose of using a webhook?
- Data Encryption
- Load Balancing
- Real-time Notification of Events
- Session Management
The purpose of using a webhook in payment gateway integrations is to receive real-time notifications of events, such as successful payments or chargebacks. Webhooks enable developers to respond promptly to transaction-related events, enhancing the efficiency and responsiveness of the payment processing system.
The process of synchronizing a user's social media profile with an application's user profile is known as ________.
- Authentication
- Integration
- Mapping
- Synchronization
Synchronization refers to the process of keeping two sets of data, in this case, a user's social media profile and the application's user profile, consistent and up-to-date with each other.
How does CodeIgniter's Active Record pattern simplify database interactions?
- It abstracts SQL queries into PHP functions
- It disables database interactions for security
- It enforces the use of raw SQL queries
- It is not related to database operations
CodeIgniter's Active Record pattern simplifies database interactions by abstracting SQL queries into PHP functions. This abstraction makes it easier to write database-agnostic code, improves code readability, and reduces the risk of SQL injection attacks. The pattern allows developers to perform common database operations using a set of convenient methods, promoting a more structured approach to handling data in CodeIgniter applications.
What is the advantage of using database seeding in a development environment?
- Enhancing security through encrypted data
- Improving database performance through indexing
- Optimizing database queries using stored procedures
- Populating the database with sample or test data
Database seeding in CodeIgniter is advantageous in a development environment as it allows populating the database with sample or test data. This facilitates testing and ensures that the application behaves as expected with realistic data scenarios.
