I thought WordPress plug-ins get managed through SVN in the official plug-in repo.
But to be honest I never thought about how premium plugins manage this.
According to ChatGPT
The prompt:
In WordPress, as a developer, how do I create a button to update a premium WordPress plugin
The answer:
To create a button that updates a premium WordPress plugin, you can follow these steps:
First, you need to integrate your plugin with WordPress’ update system. This is done by creating a custom update API that your plugin can use to check for updates and download them. You can use a library like Easy Digital Downloads or Freemius to handle the update API integration.
Once your plugin is integrated with the update system, you can create a button in the WordPress admin area that triggers the update process. This button can be added to the plugin settings page or any other appropriate location.
To create the button, you can use the WordPress function add_settings_field to add a new field to the plugin settings page. In the callback function for this field, you can output HTML for the button using the submit_button function.
In the callback function for the button click event, you can trigger the update process by calling the wp_remote_get function with the update API endpoint for your plugin.
Finally, you can display a message to the user indicating that the update process has started or has completed successfully.
Overall, the process of creating a button to update a premium WordPress plugin involves integrating your plugin with the update system, adding a button to the plugin settings page, and handling the button click event to trigger the update process.
