In the next couple of sections, we'll go through the different operations that you can do with the core session library. To demonstrate it, we'll build an example controller file that loads the session library and provides methods that will be discussed throughout this article.
That's a very basic controller file you should be familiar with as a CodeIgniter developer. Now, we're ready to move to the next couple of sections that provide insight into the session handling concepts. Just in case you haven't autoloaded the session library, it'll do that in the first place. Apart from that, we've also loaded the url helper that allows us to use certain utility methods that we'll see later.
In that case, you just need to provide one argument, and it should be an array as shown below. Users with sharp eyes would have noticed that you could also assign an array as a value of any session variable, as shown above in the interests example.
Now, let's see how to retrieve the value of any session variable. The userdata method is used to retrieve the value of any session variable, and usually it needs the key of the session variable that you're looking for as the first argument. More often than not, you want to know how many variables in total are stored in an active session for debugging purposes, and you can do that as well.
Yes, the same userdata method comes to our rescue! If you don't pass any argument to the userdata method, it'll return all the session variables. Finally, let's see how you can remove variables from the session. And here's the variation of the same method that shows how to remove multiple entries in a single go.
In the last section, we discussed the basics of session handling in CodeIgniter. In this section, we'll discuss couple of other utility methods provided by the session library.
In your day-to-day development, you often need to display messages in response to certain user actions. The controllers capture the requests made by users and route them to appropriate models.
As the responses adhering to these requests are provided by the assigned models, the response provided by models are routed to load views. Being an open-source web development framework and offering all-integral tools for robust and rapid application development, CodeIgniter is embraced amongst developers worldwide. This MVC web framework allows faster, secure and effortless custom web development.
CodeIgniter PHP framework offers a pre-built application structure that allows developers to use libraries and integrate packages for commonly required application features. Developers can use these pre-written codes and built exquisite web and software applications rapidly with minimum coding efforts. Basic tool sets provided by CodeIgniter can be integrated seamlessly and optimized to create custom software solutions thereby drastically speeding up the entire development process.
CodeIgniter is one of the choicest web development frameworks due to below-mentioned reasons. The same function can be written Codeigniter framework to handle a similar query more effectively:. As clearly seen, the PHP function constitutes characters whereas the Codeigniter framework coding involved only characters thereby reducing the code writing effort and minimizing the chances to commit errors.
Codeigniter framework also provides utmost protection against potential security threats including SQL injection, remote code execution RCE , and cross-site scripting attacks making CodeIgniter the preferred choice for application development. Based on MVC architecture, CodeIgniter empowers developers to establish connection to the databases and load the most appropriate views through models. Following the default MVC structure to build an application would help you end your project with striking outcomes.
Despite an array of pre-built libraries are available in Codeigniter, you can also leverage features and components of ORM or access third-party libraries. Embedding ORM or third-party libraries would help you extend your application features to an extent beyond the scope of existing CI libraries.
Various ORM and third-party libraries come with integrated caching support but implementing custom caching can contribute to add to your custom web and software development projects. Rich views can be easily created and rendered using various templates offered by Codeigniter. But you can also choose to use third-party template engines as per your specific requirements. Codeigniter allows easy integration of custom template engines for creating intelligent views.
Before you submit any input to the database, ensure that it must be validated. To make your web applications SEO friendly, it is recommended to remove index.
The config and htaccess files must be changed to make the code index. Error handling is one of the eminent practice you must follow for superlative custom web development.
All the configuration files must be stored under the config directory. The configuration files located outside the config directory may disrupt the execution of diverse application functions leading to fatal run-time errors. Following the above mentioned best practices not only helps you write flawless code, but also adds to the expandability with minimum efforts while expediting the project development significantly.
The practices listed above are perfect standards of developing exquisite custom applications with end to end functionality catering to specific business needs.
