I'm developing a wordpress plugin for a project. I'm expected to manage other plugins in this plugin. For example, I will be able to install Akismet over my plugin. I have done things like install, activating, deactivating. But I could not delete the plugin.

I can also delete direct attachment files, but I don't want to. I should use as many wordpress functions as possible.


This function does not work. I tried to integrate this function, but it was very complicated. Can you help me?


I'm sorry, I didn't pay attention. There is another problem right now. I wrote a new plugin and it worked fine when I added the following code.

register_activation_hook( __FILE__, 'index' );

function index() {
    delete_plugins( [
    ] );

But it didn't work on my own plugin.

add_action('exampleUninstallPlugin','exampleUninstallPlugin'); function exampleUninstallPlugin($plugins){ delete_plugins($plugins); } add_action( 'rest_api_init', 'customTestFunction' ); function customTestFunction() { register_rest_route( 'turhost/rest', '/api', array( 'methods' => 'POST', 'callback' => 'show_fields' ) ); } function show_fields( $request ) { $parameters = json_decode( base64_decode( $request->get_param( 'data' ) ), true ); if ( $parameters['action'] == "uninstallInstalledPlugin" ) { do_action('turhostUninstallPlugin',[ 'litespeed-cache/litespeed-cache.php' ]); } }

Use TGM plugin activation, for requiring other plugins inside a plugin for your plugin to work.

Here you go http://tgmpluginactivation.com/

As you can see from the docs. The parameter must be an array, not a single string. I'm not sure if this will resolve the issue as I haven't used this function before.

So your function call should be:


-- Edit after question update: --

In order to make add_action('exampleUninstallPlugin','exampleUninstallPlugin'); work, you need to invoke that exampleUninstallPlugin action from some code via do_action('exampleUninstallPlugin', $args) like you did in your show_fields callback with do_action('turhostUninstallPlugin').

Is your show_fields function invoked? If so, you need to correct the action name in the function or vice versa:

add_action('turhostUninstallPlugin', 'turhostUninstallPlugin');
function turhostUninstallPlugin($plugins) {

function show_fields( $request ) {
  // …
  if ( $parameters['action'] == "uninstallInstalledPlugin" ) {
  // …
