How does the Email Class handle attachments in an email?
- Attachments are automatically added if the email body contains file paths.
- Attachments are handled by specifying file paths directly in the to() method.
- Attachments are handled using the attach() method, which attaches files to the email.
- The Email Class doesn't support attachments.
The Email Class in CodeIgniter handles attachments using the attach() method, allowing you to include files in your emails. This method allows you to specify the file path and other relevant details.
In many programming languages, unhandled exceptions are caught by a global ________ handler.
- ErrorHandler
- Exception
- ExceptionHandler
- GlobalHandler
In many programming languages, unhandled exceptions are caught by a global exception handler. This handler can be defined to manage unexpected situations and prevent abrupt termination of the program. It plays a crucial role in gracefully handling errors at a higher level.
________ is a technique used to verify whether an input adheres to a specified format, like an email address.
- Data Binding
- Input Sanitization
- Regular Expression
- Typecasting
Regular expressions are often used for input validation, allowing developers to define specific patterns that the input must match, such as email addresses.
The ________ method in CodeIgniter is crucial for handling conditional rollbacks in transactions.
- commit
- end_transaction
- rollback
- set_rollback
The "set_rollback" method in CodeIgniter is crucial for handling conditional rollbacks in transactions. It allows you to set a flag that determines whether a transaction should be rolled back or not. This is useful when dealing with conditional logic within a transaction.
What is the primary purpose of session management in web applications?
- Enhancing security by storing user data securely
- Facilitating server-side rendering
- Improving database performance
- Managing and persisting user data across multiple requests
Session management is crucial for persisting user-specific data across different requests. It allows web applications to maintain stateful interactions with users by storing data like user preferences, authentication details, etc. This enhances the user experience and makes it easier to manage user-related information.
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 multi-step form, ensuring that each step is validated before proceeding to the next is an example of ________ validation.
- Front-to-back
- Incremental
- Sequential
- Step-wise
Sequential validation ensures that each step is validated before moving to the next. It ensures data integrity throughout the form submission process.
In a multi-threaded application, an exception in one thread should be handled in a way that ________.
- Does not affect other threads
- Pauses all threads until resolved
- Prompts the user for a resolution
- Terminates the entire application
Handling an exception in a way that does not affect other threads is essential in a multi-threaded application. Pausing or terminating the entire application is generally not recommended as it could disrupt other threads and impact the overall application stability.
Database ________ is a process of inserting initial data into the database for testing purposes.
- Insertion
- Populating
- Seeding
- Seeding:insert
Database Seeding is the process of inserting initial data into the database for testing purposes. It helps to populate the database with dummy data for testing and development.
When storing sessions in a database in CodeIgniter, the table must have a column named ________ to store session data.
- data
- session_content
- session_data
- session_payload
CodeIgniter expects a column named session_data to store session information when using a database to store sessions. The framework uses this column to store serialized session data securely. It is crucial to have this column named correctly for CodeIgniter to work seamlessly with database-backed sessions.
