To troubleshoot an issue where session data is lost after redirecting in CodeIgniter, a developer should first check the ________ configuration.
- session_cookie_secure
- session_driver
- session_renewal_interval
- session_time_to_update
When troubleshooting session data loss after redirection in CodeIgniter, check the session_time_to_update configuration. It determines the time interval for session ID regeneration, affecting session persistence during redirects.
Which function in the Email Class is typically used to set the recipient's email address?
- bcc()
- cc()
- from()
- to()
The to() function in the Email Class is used to set the recipient's email address. This function specifies the main recipient of the email and is commonly used when composing and sending emails using the CodeIgniter Email Class.
In a scenario where the database schema changes frequently, ________ helps in managing these changes effectively.
- Controller
- Database Seeder
- Routes
- Version Control
Version control is crucial for managing frequent database schema changes. It allows developers to track, revert, and collaborate on database changes effectively, ensuring consistency and traceability in the project.
In CodeIgniter, what is the significance of the 'core' subdirectory within the 'application' directory?
- It contains configuration files for the core system.
- It houses the core system files of CodeIgniter.
- It is used for storing core database configurations.
- It is where the main application logic resides.
The 'core' subdirectory within the 'application' directory contains the core system files of CodeIgniter, essential for the framework's functionality and behavior.
In CodeIgniter 4, how does the Model's 'find' method enhance data retrieval flexibility?
- Allowing cross-database querying for distributed systems
- Enabling custom SQL queries for precise data retrieval
- Facilitating the retrieval of records based on primary key values
- Implementing automatic caching for improved performance
In CodeIgniter 4, the Model's 'find' method enhances data retrieval flexibility by facilitating the retrieval of records based on primary key values. This method simplifies the process of fetching a specific record from the database, providing a convenient and efficient way to retrieve data using the primary key as a reference.
During a high traffic period, a CodeIgniter application starts throwing database errors. The best practice to handle this scenario involves ________.
- Implementing Caching Mechanisms
- Implementing Database Connection Pooling
- Increasing the Database Query Timeout
- Using Shared Database Connections
During high traffic, using shared database connections in CodeIgniter is a recommended practice. It helps manage and reuse existing database connections, reducing the impact of opening and closing connections frequently during peak times.
What file extension is typically used for views in CodeIgniter?
- .ci
- .html
- .php
- .view
In CodeIgniter, views are typically saved with a .php extension. This allows the server to interpret and process the PHP code within the view file. The .html extension is not commonly used for CodeIgniter views.
A common method to sanitize user input and prevent XSS is using ________ encoding.
- Base64
- HTML
- URL
- XSS
HTML encoding helps prevent XSS attacks by converting special characters to their HTML entities, making them harmless.
What is the purpose of the __construct() function in a CodeIgniter controller?
- Defining route configurations
- Handling HTTP requests and responses
- Initializing class properties and methods
- Loading necessary libraries and resources
The __construct() function in a CodeIgniter controller is used for initializing class properties, loading necessary libraries, and performing tasks that need to be executed before any other controller method is called.
What security risks are associated with storing uploaded files directly in the webroot directory?
- Enhanced security through isolation, reduced risk of unauthorized access
- Improved file access speed, enhanced server performance
- Increased risk of code execution, vulnerability to file inclusion attacks
- Simplified file management, easier accessibility
Storing uploaded files directly in the webroot directory poses a significant security risk, as it allows for potential code execution and makes the application vulnerable to file inclusion attacks. By placing files outside the webroot, the risk of unauthorized access is reduced.
