Backend logic (main.php) On-Premises

Sometimes it is not enough to use HTML/Javascript code for creating plugin. Often 3rd party plugins provide REST API for integration or manipulation of the system, for example:

  • shops require saving orders
  • plugins may use PHP libraries
  • plugins may require encrypting form fields before submitting what requires server-side script like PHP

To add PHP code into your plugin take the following steps:

  1. create file "main.php" in your plugin folder and write your PHP code
  2. open file "main.html" and add marker {{{requireService}}}. The marker will be replaced with PHP code in published website
  3. open file "plugins/plugins_whitelist.json" and add your plugin name to php list
Note.
PHP code is not loaded in site builder but only in published website.

Adding multiple PHP files to plugin

Let's say you develop plugin which integrates some 3rd party system to your site. This system provides PHP SDK which you want to use.
The PHP SDK can be a folder which contains one or multiple .php files, other folders containing other files, etc.
To add all this PHP library to your plugin take the following steps:

  1. create folder "site" in your plugin folder
  2. add all needed 3rd party files/folders into folder "site"

After that you will have access to folder "site" within your PHP file "main.php".
Let's presume you have file in your plugin "myplugin/site/SomeLibrary.php". Then you can load this file with line require_once("SomeLibrary.php"); in your PHP file.
