Which file in CodeIgniter is typically modified to include a third-party library?
- autoload.php
- config.php
- index.php
- routes.php
The autoload.php file in CodeIgniter is typically modified to include a third-party library. This file contains the configuration for auto-loading various resources, including libraries. Adding a third-party library to the autoload configuration ensures that it is loaded automatically when the application starts, making it readily available for use throughout the code.
In CodeIgniter, where are session data typically stored by default?
- Cookies
- Database
- Server-side files
- URL parameters
By default, CodeIgniter stores session data on the server-side in files. This provides a secure and efficient way to manage user sessions without exposing sensitive information in cookies or other less secure methods.
The technique of _________ effectively limits SQL injection by stripping out SQL commands from user inputs.
- Code Obfuscation
- Data Encryption
- Input Sanitization
- Output Validation
Input Sanitization is a security technique that involves cleansing user inputs to remove potentially harmful content, such as SQL commands. This helps prevent SQL injection attacks by ensuring that only valid and safe data is processed.
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.
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.
