Divi PHP Code Module allows users to seamlessly integrate and run PHP code directly within their Divi Builder pages. This powerful module enables the addition of dynamically-generated content, execution of complex server-side logic, and interaction with databases – all from within the Divi Builder interface.

How to Use Global Variables

Global variables in PHP are accessible from any part of your script after they have been defined. It is possible to use global variables with the Divi PHP Code Module, allowing data to be shared an communicated between multiple instances of the module. Here's how to set and read global variables within the Divi PHP Code Module:

Setting a Global Variable

To set a global variable, you can add code like this in a Divi PHP Code module:

For example:

To read the previously set global variable, use code like this in another Divi PHP Code module:

For example:

Notes

When using global variables with the Divi PHP Code module, here are some things to keep in mind:

1. Scope Management: Since the PHP code in the Divi PHP Code module is executed within the context of a class method, you must use the global keyword to access global variables.
2. Execution Order: You can only read a global variable from a module that is executed after the module where the variable was set. This means that it’s not possible to read a global variable from an earlier module.
3. Visual Builder Limitations: The preview in the Divi Visual Builder (activated by the green "play" button) renders each module independently. Due to this, the visual builder won't be able to reflect changes made to global variables by other modules. However, on the front-end, all modules will share access to global variables correctly.
4. Naming Conventions: To prevent conflicts with existing global variables on your site, give your global variables unique names or prefixes. This practice avoids unintended overwriting or mismanagement of variables that could disrupt the functionality of your site.
