Passing Data Into View Files
Passing data into view files in Trongate involves initializing an associative array within a controller and passing it to the view() method. This array contains variables that can be accessed directly within the view for dynamic content rendering.
Basic Data Passing
The technique for passing data from controller files into view files comprises of the creation of an associative array of key-value pairs. This data array is then passed as the second argument to the view() method:
This example initializes $data with user information and renders the 'welcome' view, where variables like $first_name and $last_name can be accessed directly.
Complex Data Types
You can pass various data types such as arrays, objects, and booleans into view files. For instance, consider passing an array of cities and today's date to a view:
Accessing Passed Data
Within view files, accessed data is available as standard variables. For debugging or development purposes, you can use:
To display structured data in a formatted manner, use Trongate's json() method:
Example: Rendering Dynamic Content
Enhance the greeting() method to pass a name variable into a view file:
In the 'greeting.php' view file, you can directly echo the $name variable:
Output:
When rendering data from untrusted sources like user inputs, always sanitize outputs to prevent security vulnerabilities. Trongate provides the json() function for safe output encoding, protecting against XSS attacks by properly formatting content for HTML, XML, JSON, JavaScript, and HTML attributes.
