Make plugin install plugin

So I decided to work as a plugin developer for another server just for fun, and he wants me to make a ShopGUI. At first, I was going about it, then I thought about something. I asked the owner if he/she was using EconomyAPI and when he said no I got shaken, because all the other plugins the other developers he/she hired also were making plugins that depended on it. I want to see if there is any way to install plugins through another plugin, so I don't have to deal with the stubborn owner.

Thank you so much in advance!

 

Sure you can, just download a phar from Poggit using a preferred method (file_get_contents, curl, BulkCurlTask) and save it to the plugins folder, then force stop the server so the owner has to restart it

 

Thank you so much! After doing some Google searches, I found a way to install plugins using file_get_contents, here is my code:

PHP:

private $forced = false;

    public function onEnable(){
        Server::getInstance()->getLogger()->info(TextFormat::GREEN . "ShopUI by TheSacrafice (@ethaniccc) has been enabled!");
        $this->loadCommands();
        $this->getScheduler()->scheduleDelayedTask(new ClosureTask(function(int $currentTick) : void{
            $economy = Server::getInstance()->getPluginManager()->getPlugin("EconomyAPI");
            if($economy === null || $economy->isDisabled()){
                $this->forced = true;
                Server::getInstance()->getLogger()->error("EconomyAPI is not installed on the server! Attempting to install!");
                $download = file_get_contents('https://poggit.pmmp.io/r/34531/EconomyAPI.phar');
                if($download === false){
                    Server::getInstance()->getLogger()->emergency("EconomyAPI failed to install! Disabling ShopUI!");
                    Server::getInstance()->getPluginManager()->disablePlugin($this);
                } else {
                    file_get_contents('https://poggit.pmmp.io/r/34531/EconomyAPI.phar');
                    $filename = 'plugins/EconomyAPI.phar';
                    $save = file_put_contents($filename, $download);
                    if($save === false){
                        Server::getInstance()->getLogger()->emergency("EconomyAPI failed to install! Disabling ShopUI!");
                        Server::getInstance()->getPluginManager()->disablePlugin($this);
                    } else {
                        file_put_contents($filename, $download);
                    }
                }
                //Server::getInstance()->getPluginManager()->disablePlugin($this);
            }
        }), 60);
        if(!InvMenuHandler::isRegistered()){
            InvMenuHandler::register($this);
        }
    }

    public function onDisable(){
        Server::getInstance()->getLogger()->warning("ShopUI by TheSacrafice (@ethaniccc) has been disabled!");
        if($this->forced === true){
            Server::getInstance()->getLogger()->info(TextFormat::GREEN . "EconomyAPI has been installed on the server! Please wait a few seconds...");
        }
    }

Forgot to shutdown the server, but it still works

 

PHP:

private $forced = false;

    public function onEnable(){
        Server::getInstance()->getLogger()->info(TextFormat::GREEN . "ShopUI by TheSacrafice (@ethaniccc) has been enabled!");
        $this->loadCommands();
        $this->getScheduler()->scheduleDelayedTask(new ClosureTask(function(int $currentTick) : void{ // why did you put it in a task?
            $economy = Server::getInstance()->getPluginManager()->getPlugin("EconomyAPI");
            if($economy === null || $economy->isDisabled()){
                $this->forced = true;
                Server::getInstance()->getLogger()->error("EconomyAPI is not installed on the server! Attempting to install!");
                $download = file_get_contents('https://poggit.pmmp.io/r/34531/EconomyAPI.phar');
                if($download === false){
                    Server::getInstance()->getLogger()->emergency("EconomyAPI failed to install! Disabling ShopUI!");
                    Server::getInstance()->getPluginManager()->disablePlugin($this);
                } else {
                    file_get_contents('https://poggit.pmmp.io/r/34531/EconomyAPI.phar'); // why are you downloading it again
                    $filename = 'plugins/EconomyAPI.phar'; // I recommend using Server->getPluginPath() instead
                    $save = file_put_contents($filename, $download);
                    if($save === false){
                        Server::getInstance()->getLogger()->emergency("EconomyAPI failed to install! Disabling ShopUI!");
                        Server::getInstance()->getPluginManager()->disablePlugin($this);
                    } else {
                        file_put_contents($filename, $download); // why are you saving it again?
                    }
                }
                //Server::getInstance()->getPluginManager()->disablePlugin($this);
            }
        }), 60);
        if(!InvMenuHandler::isRegistered()){
            InvMenuHandler::register($this);
        }
    }

    public function onDisable(){
        Server::getInstance()->getLogger()->warning("ShopUI by TheSacrafice (@ethaniccc) has been disabled!");
        if($this->forced === true){
            Server::getInstance()->getLogger()->info(TextFormat::GREEN . "EconomyAPI has been installed on the server! Please wait a few seconds...");
        }
    }
