[Help Needed] in_array() expects parameter 2 to be array

HI! I've been working on a fix on this. I need some assistance on this. Any help would be appreciated..

Error:

PHP:

in_array() expects parameter 2 to be array, null given in /plugins/ChatterBot/src/RTG/ChatterBot/Main.php on line 95


Code:

PHP:

    public function onChat(PlayerChatEvent $e) {
      
        $msg = strtolower($e->getMessage());
        $p = $e->getPlayer();
        $n = $p->getName();
        $in = strtolower($this->cfg->get("interactions"));
          
            if(in_array($msg, $in)) {
              
                switch(mt_rand(1, 3)) {
                  
                    case "1":
                        $p->sendMessage("Hey, " . $n . "!");
                    break;
                    case "2":
                        $p->sendMessage("Holla, " . $n . "!");
                    break;
                    case "3":
                        $p->sendMessage("Bonjour, " . $n . "!");
                    break;
              
                }
                  
            }
            else {
                $this->getLogger()->warning("Error, not found!"); // DEBUG line for testing
            }
          
    }


Config:

Code:

---
# Author: IG
# For better usage and reply from the vote, please use the word 'bot' infront of your question or message! ( not mandatory ).
# Don't worry about 'upper case' or 'lower case', this bot will read it :D
interactions:
    - "Heya"
    - "hey"
voting:
    - "Your voting question"
    - "How to vote?"
    - "Add how many as you want!"
votingsite:
    - "Your voting site's link"
    - "You can have multiple links!"
...

Try without using space on the config like

Code:

interactions:
- "Hello
- "hey"

 

Does that make difference?

 

I think so! try it.

 

Error:

Code:

18.02 02:32:03 [Server] INFO Warning: in_array() expects parameter 2 to be array, null given in /plugins/ChatterBot/src/RTG/ChatterBot/Main.php on line 95 
18.02 02:32:03 [Server] INFO Warning: strtolower() expects parameter 1 to be string, array given in /plugins/ChatterBot/src/RTG/ChatterBot/Main.php on line 93

 

Ohh! Got it! Remove the strtolower() function!

 

I'd need the plugin to get all the messages lower case instead of upper case. It won't be doing that if i remove

PHP:

strtolower()

 

remove the strtolower() of $in cause the strtolower() needs string and you given array!

 

Then foreach the array of strings, strtolower them then cache/store the result.

 

Thanks, i've fixed it! https://github.com/RTGDaCoder/ChatterBot/commit/7e50a312da1264fcc17e7f75fb140993ee537646

 

Thanks SOFe, appreciate it!
