Adding Dynamic Content

In this section, we will explore how to add dynamic content to our CodeIgniter application while integrating Bootstrap.

We will cover passing data from the controller to the view, manipulating the data in CodeIgniter, and displaying it using Bootstrap.

Additionally, we will implement dynamic features like dropdowns, modals, etc.

1. Passing data from the controller to the view

One of the crucial aspects of building dynamic web applications is passing data from the backend (controller) to the frontend (view).

CodeIgniter provides an easy-to-use mechanism for achieving this.

To pass data from the controller to the view, we can use the CodeIgniter’s $this->load->view() method along with an associative array to store the data.

For example:

$data = array(
'title' => 'My Page',
'content' => 'Welcome to my page!'
);

$this->load->view('my_view', $data);

Inside the view file, we can access the passed data using PHP variables, just like we normally do:

<h1><?php echo $title; ?></h1>
<p><?php echo $content; ?></p>

2. Manipulating data in CodeIgniter and displaying it using Bootstrap

CodeIgniter provides a wide range of libraries and helpers to manipulate and format data before displaying it to the user.

By combining this with Bootstrap’s styling, we can create visually appealing and user-friendly dynamic content.

For example, we can use CodeIgniter’s date_helper to format dates before displaying them with Bootstrap’s text-muted class:

<p class="text-muted"><?php echo nice_date($date, 'F j, Y'); ?></p>

This will display the date in a more human-readable format, such as “January 1, 2022”.

3. Implementing dynamic features like dropdowns, modals, etc.

Bootstrap offers a range of dynamic features that can enhance the user experience of our web application.

By integrating these features with CodeIgniter, we can create interactive and functional components.

For example, we can implement a dropdown menu using Bootstrap’s dropdown class and CodeIgniter’s database functionality:

<div class="dropdown">
<button class="btn btn-primary dropdown-toggle" type="button" data-toggle="dropdown">
Select a category
</button>
<div class="dropdown-menu">
<?php foreach($categories as $category): ?>
<a class="dropdown-item" href="#"><?php echo $category; ?></a>
<?php endforeach; ?>
</div>
</div>

This will create a dropdown menu with dynamically populated categories retrieved from the database.

In general, by integrating Bootstrap with CodeIgniter, we can easily add and manipulate dynamic content in our web application.

Whether it is passing data from the controller to the view, formatting and displaying data using Bootstrap’s styles, or implementing dynamic features like dropdowns and modals, CodeIgniter provides an effective framework for building robust and visually appealing applications.
