- Ensuring secure password storage
- Mitigating cross-site request forgery
- Preventing unauthorized data submission
- Protecting against cross-site scripting
CodeIgniter's CSRF protection aims to prevent unauthorized data submission by generating and validating unique tokens for each request.
Describe the role of seeding in automated testing scenarios.
- Test Data Generation
- Code Optimization
- Performance Testing
- Automated Deployment
Seeding in CodeIgniter involves generating test data for automated testing scenarios. The "Test Data Generation" option accurately reflects the role of seeding in providing consistent and reproducible data for testing purposes.
Which file needs to be modified to autoload a custom library in CodeIgniter?
- autoload.php
- config.php
- database.php
- index.php
In CodeIgniter, to autoload a custom library, you need to modify the autoload.php file located in the config folder. This file contains the configuration settings for autoloading various resources, including libraries. You can add your library to the autoload configuration array in this file to load it automatically when the application starts.
For a report generation module that involves multiple table joins and specific conditions, the recommended approach using Active Record Class is: ________.
- get()
- join()
- select()
- where()
The recommended approach is to use join() for multiple table joins, followed by where() to specify conditions, and then use select() to choose the columns needed. Finally, execute the query with get().
What is the primary function of the Query Builder in CodeIgniter?
- Building queries in an object-oriented manner
- Executing raw SQL queries
- Handling user authentication
- Managing file uploads
The primary function of the Query Builder in CodeIgniter is to build queries in an object-oriented manner. This allows developers to construct SQL queries using a convenient and secure syntax provided by CodeIgniter. It aids in creating complex queries without directly writing raw SQL, promoting better code organization and preventing common SQL injection vulnerabilities.
What is the primary purpose of form validation in web applications?
- To create dynamic form layouts
- To encrypt form data before submission
- To ensure the form looks aesthetically pleasing
- To validate and sanitize user input
Form validation is crucial for verifying user input to prevent malicious data entry, ensuring data integrity, and enhancing security. It helps in preventing common issues like SQL injection and ensures that the received data meets specified criteria.
To maintain session data across multiple requests, CodeIgniter uses a unique identifier known as a ________.
- hash
- nonce
- session_id
- token
CodeIgniter uses a unique session_id to maintain session data across multiple requests. This identifier is used to associate the user's session data with their interactions on the site.
Where are the custom libraries stored in the CodeIgniter directory structure?
- application/libraries
- codeigniter/libraries
- custom/libraries
- system/libraries
Custom libraries in CodeIgniter are stored in the 'application/libraries' directory. This allows developers to extend the framework's functionality by creating and using their own libraries tailored to the application's needs.
To pass data from a controller to a view, the data should be stored in an associative ________.
- Array
- Integer
- Object
- String
To pass data from a controller to a view in CodeIgniter, the data should be stored in an associative array. This array is then passed as the second parameter to the $this->load->view() function.
In complex queries, CodeIgniter Models use ________ to join multiple tables.
- connect()
- join()
- link()
- merge()
CodeIgniter Models use the join() method to perform JOIN operations in complex queries. This method helps in combining data from multiple tables based on specified conditions.
