Error in plugin

Hi, im getting this error in my plugin

Notice: Undefined variable: gettheme in C:\Users\server\Desktop\servers\test\plugins\BuildBattle_v1.0 (1)\src\Kabluinc\BuildBattle\BuildBattle.php on line 645

My code is
$type = ("car");
$themes = new Config($this->plugin->getDataFolder() . "/themes.yml", Config::YAML);
$themes->set("theme", $type);
$themes->save();
$gettheme = $themes->get("theme");
}
if($timeToStart<=0)
{

foreach($playersArena as $pl)
{

$pl->sendPopup($gettheme);

And the config created was
---
theme: car
...

Why am i getting that error?
ik theres no point in having $gettheme but still why doesnt it work

Can you please use the [ PHP ] [/ PHP ]?(without those spaces. Put your code inside.)
Also, please point out the line.

Sorry. The line that the error is in is

$gettheme = $themes->get("theme");

The themes in config wasn't set when the config file was created, add it using:

PHP:

$gettheme = new Config($this->plugin->getDataFolder() . "/themes.yml", Config::YAML, array (
     "themes" => car
   ));


Sorry, change getthem into themes

Actually, how can i get the plugin to choose a random theme and display it on a popup?

iv tried Setting config with

---
themes:
- car
- boat
- park
...

How do i get a random theme from the themes.yml and player->sendPopup without it refreshing with a new random theme every tick. That what happened when i last tried it. Every second it keeps looping and getting a new random theme

save theme array in local variable.

PHP:

$themes = $config->getAll();

//then you can get random theme 
$theme = $themes[array_rand($themes)];
[PHP]

WTF WTF WTF
There was a $themes = new Config() line above it!

Read the reply after that i said change change $themes not creating a new one

Pls help me with this

Ok so when the plugin loads.. this code is run

PHP:

$themes = new Config($this->getDataFolder() . "/themes.yml", Config::YAML);
        $theme = array(array("Puppy"),array("IceCream"),array("Herobrine"),array("Computer"),array("Laptop"),array("car"),array("Spongebob"),array("Squid"),array("Wolf"),array("Ocelot"));
    if($themes->get("Themes")==null)
    {
        $themes->set("Themes",$theme);
        }
        $themes->save();

Then this code is run before game start

PHP:

$themes = new Config($this->plugin->getDataFolder() . "/themes.yml", Config::YAML);
     $theme = $themes->getAll();
     $buildingtheme = $theme[array_rand($theme)];

But when i use $buildingtheme when the game starts to display a theme on $player->sendMessage("Theme" .$buildingtheme . "");

Ingame it displays blank for theme and in console it shows
Notice: Undefined variable: buildingtheme in C:\Users\server\Desktop\servers\test\plugins\BuildBattle_v1.0 (1)\src\Kabluinc\BuildBattle\BuildBattle.php on line 645

Maybe try spacing between . And $buildingtheme? And why you need to add ""?

Using this

PHP:

$player->sendMessage("Theme:" . $buildingtheme .);

Crashed the server with error:
Server thread/CRITICAL]: ParseError: "syntax error, unexpected ')'" (EXCEPTION) in "/plugins/BuildBattle_v1.0 (1)/src/Kabluinc/BuildBattle/SkyWars" at line 698

Using

PHP:

$player->sendMessage("Theme:" .$buildingtheme . "");

The server loads, game starts but it displays Theme: (nothing)
And in console undefined variable $buildingtheme error

What shud i do

PHP:

$player->sendMessage("Theme:" . $buildingtheme);


Nope. That still showed the undefined variable error

Now one thing i found does work is
this before game start

PHP:

$themes = array("Botanic Garden", "Witches Hut", "Mobile Phone", "Christmas tree", "Sea Side", "Cake", "Wind Mill", "Statue of yourself", "Cup cake", "Shed");
                     $theme = $themes[rand(0, 9)];

Then i used

PHP:

$player->sendPopup("Theme:" . $theme);

It shows themes correctly but it keep changing the theme to a new random one each tick. So the popup doesnt stay to just one theme. How to fix this?

You bothered posting another post but didn't choose to edit the original post? Use the Edit button! :facepalm:

PHP:

$type = ("car");
$themes = new Config($this->plugin->getDataFolder() . "/themes.yml", Config::YAML);
$themes->set("theme", $type);
$themes->save();
$gettheme = $themes->get("theme");
} //You closed it and want to use it after this line?!?
if($timeToStart<=0)
{

foreach($playersArena as $pl)
{

$pl->sendPopup($gettheme);

The first } is the problem

T

True. But you can also

PHP:

$type = ("car");
$themes = new Config($this->plugin->getDataFolder() . "/themes.yml", Config::YAML);
$themes->set("theme", $type);
$themes->save();
$gettheme = $themes->get("theme");
if($timeToStart==0){
foreach($playersArena as $pl){
$pl->sendPopup($gettheme);
}
}


Originally when someone develops an plugin, or somethink another, he doesnt write "{" before "if"

And I'm not master with configs, but I think, that you selected all words in "themes".
If you making this for yourself, I recomended:

PHP:

$rand=mt_rand(1, 3){
switch($rand){
case 1:
$theme = §6Car;
break;
case 2:
$theme = §6Tank;
break;
case 3:
$theme = §6Build anythink what you want;
break;
}
if($timeToStart<=0){
foreach($playersArena as $pl){
$pl->sendPopup("§bTheme" .$theme.);[
}
}/PHP]

Oh, somethink is wrong!!!
On first line is:

PHP:

$rand=mt_rand(1, 3);

I forgotted it, sorry
