When implementing a Content Security Policy (CSP) to protect against XSS, a developer needs to ensure that ________ to avoid unintended script blockages.
- Data URIs
- External Scripts
- Inline Scripts
- Unsafe Inline
Content Security Policy (CSP) is a security standard that helps prevent XSS attacks. "Unsafe Inline" allows inline script execution, but it's important to avoid it whenever possible to enhance security.
Where should custom libraries be placed within the CodeIgniter directory structure?
- application/helpers
- application/libraries
- system/helpers
- system/libraries
Custom libraries in CodeIgniter should be placed in the application/libraries directory. This ensures that they are easily accessible and follow the CodeIgniter directory structure conventions.
To enable database caching in CodeIgniter, the $db['default']['cache_on'] setting must be set to ________.
- 0
- 1
- FALSE
- TRUE
In CodeIgniter, setting $db['default']['cache_on'] to true enables database caching, and setting it to false disables caching. This configuration helps optimize database performance by caching query results for a specified period, reducing the need to re-run queries.
The ________ feature in CodeIgniter allows the application to run different environments seamlessly.
- Environment Configuration
- Environment Loader
- Environment Setup
- Environment Switching
The Environment Configuration feature in CodeIgniter enables the application to seamlessly run in different environments.
Explain the role of 'trans_status()' function in CodeIgniter's transaction management.
- 'trans_status()' checks whether the current transaction is active or has been rolled back.
- 'trans_status()' is deprecated in the latest CodeIgniter versions.
- 'trans_status()' is used to initiate a new transaction in CodeIgniter.
- 'trans_status()' returns true if the transaction has been successfully completed and false otherwise.
'trans_status()' is a function in CodeIgniter that checks whether the current transaction is marked as successful or has been rolled back. It returns a boolean value, true if the transaction has been successfully completed, and false if it has been rolled back or if no transaction is in progress. This function is handy for checking the status of a transaction and making decisions based on whether it was successful or not.
In CodeIgniter, how can you extend the session timeout for a user?
- By adjusting the session timeout setting in the config.php file.
- By modifying the session timeout directly in the database.
- By using the session_extend method in the session library.
- CodeIgniter does not provide a way to extend session timeouts.
By adjusting the session timeout setting in the config.php file. CodeIgniter allows developers to set the session timeout in the config.php file using the sess_expiration parameter. By increasing the value of this parameter, you can extend the session timeout for a user, providing a more flexible and customizable approach to session management in your CodeIgniter applications.
How can you pass multiple data items to a view in CodeIgniter?
- $this->load->data()
- $this->load->vars()
- $this->view->set()
- $this->view->set_data()
In CodeIgniter, the recommended method for passing multiple data items to a view is by using $this->load->vars(). This method accepts an associative array, making it easy to pass and organize multiple data items for the view.
When a new version of the API is deployed in CodeIgniter, maintaining backward compatibility is crucial for ________.
- API documentation
- Existing client applications
- SEO rankings
- User experience
Backward compatibility is essential for existing client applications that rely on the API. If backward compatibility is not maintained, existing clients may break, leading to a poor user experience. It also ensures a smooth transition for clients using older versions of the API, allowing them time to update and migrate to the new version without disruption.
The process of ________ is used by payment gateways to verify the funds and account details.
- Authentication
- Authorization
- Encryption
- Validation
In a payment gateway integration, the term "validation" refers to the process of confirming the legitimacy and accuracy of the provided information, ensuring the funds are available, and verifying the account details before completing a transaction. This step is crucial for security and financial integrity.
What is the primary purpose of unit testing in CodeIgniter?
- Analyzing database performance
- Detecting syntax errors
- Evaluating the user interface
- Verifying that individual units of code work as expected
Unit testing in CodeIgniter serves the purpose of verifying that individual units of code, such as functions or methods, work as expected. It ensures that each unit functions correctly in isolation before integrating them into the complete system, enhancing code reliability and maintainability.
