In CodeIgniter, which directory is designated for storing view files?
- application/views
- code/views
- content/views
- system/views
In CodeIgniter, the application/views directory is designated for storing view files. Views are responsible for presenting the data to the user. This separation helps in maintaining a clean structure and follows the MVC pattern where views handle the presentation logic.
How does seeding differ from normal data entry in a database?
- Normal data entry involves entering data through user interfaces
- Seeding and normal data entry are the same
- Seeding is only used for populating tables with empty records
- Seeding is the process of adding initial data to the database for testing purposes
Seeding in CodeIgniter refers to the process of adding initial data to the database, typically for testing and development. It is different from normal data entry, which involves inserting data through user interfaces or forms during regular usage of the application.
The function $this->load->view('view_name', $data); in CodeIgniter is used to load a view and pass ________ to it.
- Data
- Libraries
- Models
- Styles
The function $this->load->view('view_name', $data); in CodeIgniter is used to load a view and pass data to it. The data variable is an associative array containing information that needs to be displayed in the view.
How does CodeIgniter's Query Builder handle complex queries involving subqueries?
- By employing the join_subquery() function
- By using the select_subquery() method
- By utilizing the where_in_subquery() method
- Through the from_subquery() method
CodeIgniter's Query Builder supports subqueries using the join_subquery() function, allowing for the integration of subqueries in complex queries.
In the context of file uploads, what is the significance of implementing a file integrity check?
- Detects and prevents tampering or corruption of uploaded files
- Ensures file confidentiality, restricts access to privileged users
- Simplifies file metadata management, improves searchability
- Verifies file format compatibility, enhances cross-browser support
Implementing a file integrity check is essential for detecting and preventing tampering or corruption of uploaded files. This ensures that the files remain intact and unaltered, maintaining the integrity of the data throughout the upload process.
In CodeIgniter, Helpers are not classes but a collection of ________.
- Components
- Functions
- Libraries
- Modules
In CodeIgniter, Helpers are collections of functions, not classes. They are typically stored in the application/helpers directory.
When a web application crashes due to a database error, the first step in exception handling should be to check the ________.
- Database connection and credentials
- Front-end code
- Network connectivity
- Server logs
In the event of a database error, checking server logs is crucial for identifying the root cause and understanding the error details. Examining front-end code or network connectivity is less likely to reveal insights into the database issue.
In CodeIgniter, unit tests are typically written in which programming language?
- JavaScript
- PHP
- Python
- Ruby
Unit tests in CodeIgniter are typically written in PHP, as it is the primary language for CodeIgniter development. The Unit Testing Library in CodeIgniter is designed to work seamlessly with PHP, allowing developers to write effective unit tests for their PHP code.
What is the primary goal of SQL injection attacks?
- Code execution
- Data manipulation
- Server overload
- Unauthorized access to a database
SQL injection attacks aim to gain unauthorized access to a database by exploiting vulnerabilities in the input handling of SQL queries. Attackers try to manipulate or extract sensitive data by injecting malicious SQL code.
A security audit requires tracking unauthorized access attempts in a CodeIgniter application. This can be done by analyzing the ________.
- Access Logs
- CSRF Token Usage
- Error Logs
- Session Data
Analyzing the Access Logs is crucial for tracking unauthorized access attempts during a security audit. Access Logs provide information about requests made to the application, helping identify potential security threats.
