This code must save user input as a widget in the database. Start by creating an HTML form with fields corresponding to the structure of the student table.

This prevents the submit field from being part of the form post array. The model uses this array when adding the record to the database; if the submit field were included, the database insert would fail. Listing 6. To do so, add a create function to the Student controller, shown in Listing 7. Listing 7. The MStudent model is responsible for interacting with the student table in the database.
In the. Its code is shown in Listing 8. Listing 8.

The function takes two arguments: the name of the table and an associative array of field names and values. This time, put some data into the fields and click Submit. The page will refresh, and the fields will be emptied.
Begin by updating the MStudent model with a function to retrieve the student table records, as shown in Listing 9. Listing 9. Next, add a function to the Student controller called listing that loads the MStudent model and executes the listStudents function, as seen in Listing Listing You can create virtual hosts using your Apache server. First off, you need to make sure your document root is synched with the installation directory of CodeIgniter.
You can do this by opening the virtual host file:. Once opened, look for the following block and insert the install directory ahead of Document Root:. For the next change, some context is needed. As you can see, index. For the purposes of good development practices, we want to get rid of it altogether. This is only half of the work done. This will prompt Apache to list various capabilities of the server. If not, execute this line:. This will create and open the.
Place the following lines in the file, save it and exit:.
Finally, you need to let Apache know that it needs to look at the newly created. In order to achieve this, open the virtual hosts file again, and ensure AllowOverride is set to All:. As a result, your URLs will look squeaky clean. To truly understand what makes frameworks like CodeIgniter worth your while, we need to dedicate some of this guide to learning more about MVC. MVC is predominantly a web development architecture paradigm, which recommends that in any given application, the business logic needs to be decoupled with the presentation.
It divides the application into three functional parts: Models do all the dirty work — they are responsible for dealing with your database, carrying out computations etc. In short, it is where your business logic is located.
Views, on the other hand, have nothing to do with the logic of your application. They form the presentation layer of the application, where the data coming from your models is embedded when loading web pages. Controllers are the binding force between models and views. They route user requests to relevant models, and once the model has done its job, they load the relevant view.
Only snippets of PHP code are present, to display the data provided by the models. MVC gives developers added flexibility in terms of code reusability and separation of design and development. And as both views and models are entirely separate, the front-end developers can work in parallel with the back-end team greatly reducing total development time.
In the previous section, we saw how to remove index. As a result, this template translates to URLs similar to the following:. Any further parameters can be supplied in a similar fashion, separated by slashes. As you can see, routing is extremely user-friendly in CodeIgniter.
Another important feature of CodeIgniter is — its encouragement of reusing existing solutions to carry out common tasks quickly. CodeIgniter does this by providing libraries and helper functions helpers. A competitive edge of CodeIgniter is also the fact that developers can pick and choose which libraries to load and when to load them. This results in blazing fast, light-weight yet feature-rich applications, as libraries are loaded on-demand.
Loading a library is very simple in CodeIgniter.
For instance, to load the Database library, simply pass the following line in your model or controller models are recommended, albeit optional in CodeIgniter:. Of course, some libraries and helpers are so common that it is, in fact, better to autoload them right at the start of your application boot-up.
Examples include the Database library, as databases are an essential part of any modern web application, and the URL helper function which can prove to be useful in loading URLs easily. In order to autoload the Database library, open the following file:. You can autoload additional libraries in the array method, separated by commas. By getting to know more about MVC, we hope that you can further appreciate the many wonders of CodeIgniter.
Okay, with the formalities out of the way, we can finally get to the meat of the tutorial. At this point of our CodeIgniter tutorial, you should have a running distribution of CodeIgniter with the changes we made when configuring it in Step 2.
You should also be familiar with how models, views, and controllers work in CodeIgniter. In this section, we will use that knowledge to create a simple CodeIgniter web application. The app will be fairly simple in design: The controller will be used to route requests between the model and the view.

Once you get a grip on these fundamentals of CodeIgniter, you can go ahead and start building rich web applications. For our sample application, we need to create a single table titled reviews with 3 columns named id primary key and auto-incremented , title and grade.
You should go ahead and create this table, as it will form the basis of our application.
CodeIgniter should have access to your database if you followed the instructions in Step 2. After creating the table, fill it with some mock values. After we have our database all sorted out, we can begin working on our business logic. To do this, we will create a model, which will get the values from the database. Also note that the first letter of your class is uppercase — CodeIgniter requires all class names to begin with a capital letter. Now, you need to load the Database library that we talked about in Step 3.There are many types of libraries included with CodeIgniter, and many more released by community members.
If you enable the database option then you'll need to create a database table, by using the steps given next. If you simply left your forms bare, with no validation, and then stored this information directly in a database, you are liable to attack.
This is for two reasons: The database library also makes changing between database types—from MySQL to Oracle, for example—easier, because it acts as a wrapper and provides many functions for us to use on the database.
