Displaying Dynamic Data
In views, dynamic data is information that changes based on user input, database values, or application state, rather than being hard-coded. It is displayed using variables and simple logic inside templates.
In MVC, the controller prepares this data and passes it to the view, where PHP tags are used to output it. For example, a controller can send a user’s name to the view, and the page will display a personal greeting based on who is logged in.
welcome.php
1234567891011121314<!DOCTYPE html> <html> <head> <title>Welcome</title> </head> <body> <h1> <?php echo "Hello, " . htmlspecialchars($username) . "!"; ?> </h1> <p> Welcome to your dashboard. </p> </body> </html>
When the controller renders this view, it provides a value for the "$username" variable. The PHP code inside the HTML outputs the value wherever you place it, so the greeting will be different for each user. This approach is useful because it separates your logic (in the controller) from your presentation (in the view), and lets you reuse the same template for many users or situations without editing the HTML each time.
user_list.php
123456789101112131415161718<!DOCTYPE html> <html> <head> <title>User List</title> </head> <body> <h2>Registered Users</h2> <ul> <?php if (empty($users)): ?> <li>No users found.</li> <?php else: ?> <?php foreach ($users as $user): ?> <li><?php echo htmlspecialchars($user); ?></li> <?php endforeach; ?> <?php endif; ?> </ul> </body> </html>
Using conditional statements and loops in your views allows you to handle data sets and cases where no data is available. For example, you can display a list of users or show a message when the list is empty.
By working with dynamic data, your views automatically update based on user actions or database changes. This makes your application more interactive and provides a richer experience than static HTML.
