Loading Modules From Views

Within the Trongate framework, it is possible to load another module from within a view file. This capability provides additional flexibility and allows for dynamic content generation within views.

To load a module from a view file, use the following syntax:

<?= Modules::run("module_name/method_name") ?>

Why Use This Approach?

There are various scenarios where loading a module from within a view file can be advantageous. For instance, consider the need to include a 'Stripe' payment button on a webpage. When users click the 'Buy Now' button, a pop-up might appear, prompting the user to enter payment details. The implementation of such a feature can be complex and is best handled by a dedicated 'stripe' module.

Having a separate 'stripe' module that manages everything related to Stripe payments, including rendering the pop-up payment modal, allows you to maintain clean and organized code. This module can be easily called from any view file with a single line of code, as shown below:

<?= Modules::run("stripe/render_payment_button") ?>

Passing Arguments

When calling modules from view files, arguments can be passed to the methods. This is done by separating the arguments with commas. Below is an example where a variable called $name is passed as an argument:

<?= Modules::run("welcome/greeting", $name) ?>

The equals symbol (=) in the opening PHP short tag is crucial. It tells PHP to echo (display) the output. While the equals symbol is commonly used for displaying output, it is not strictly necessary if you are not displaying anything (e.g., calling a method that sends an email). For instance, the following code, using long PHP tags, would achieve the same result:

<?php
echo Modules::run("welcome/greeting", $name);
?>
