flashbangpro Posted October 20, 2011 Share Posted October 20, 2011 Hi I am still learning PHP and have a project due. I haven't had any PHP classes so I am struggling with this project. It is suppose to be a text only output pinball simulation. It calculates the players skill level randomly, there are 4 bumpers and for banks, it calculates how many times each bumper and bank is hit and calculates the score outputting all info in text no formatting. My code looks like it should work but doesn't output correctly and I can't figure out way. Here is the output : Notice: Undefined variable: skillLevel in C:\xampp\htdocs\pinball.php on line 39 Notice: Undefined variable: skillLevel in C:\xampp\htdocs\pinball.php on line 39 Notice: Undefined variable: skillLevel in C:\xampp\htdocs\pinball.php on line 42 Notice: Undefined variable: skillLevel in C:\xampp\htdocs\pinball.php on line 42 Notice: Undefined variable: skillLevel in C:\xampp\htdocs\pinball.php on line 45 Notice: Undefined variable: skillLevel in C:\xampp\htdocs\pinball.php on line 45 Notice: Undefined variable: skillLevel in C:\xampp\htdocs\pinball.php on line 48 Notice: Undefined variable: skillLevel in C:\xampp\htdocs\pinball.php on line 48 Notice: Undefined variable: skillLevel in C:\xampp\htdocs\pinball.php on line 51 Notice: Undefined variable: skillLevel in C:\xampp\htdocs\pinball.php on line 51 Notice: Undefined variable: skillLevel in C:\xampp\htdocs\pinball.php on line 54 Notice: Undefined variable: skillLevel in C:\xampp\htdocs\pinball.php on line 54 Welcome To God Mode!

KevinM1 Posted October 20, 2011 Share Posted October 20, 2011 You need to pass the appropriate values into your functions via their argument lists. In other words: function launch($skillLevel) { // rest of function } // AND, when you want to invoke it: launch($skillLevel); Also, NEVER use 'global'. Pass parameters through a function's argument list. That's why it's there. In fact, stop using whatever source you're using to learn PHP. 'Global' is a clear sign of doing it wrong, which calls into doubt everything else your resource is trying to instruct. Regarding functions (and just about everything else), go to the manual for more information: functions Quote Link to comment Share on other sites More sharing options...
flashbangpro Posted October 20, 2011 Author Share Posted October 20, 2011 Thank you I'll try and see if i can get that to work. I have just been trying to learn from online tutorials. Quote Link to comment Share on other sites More sharing options...
flashbangpro Posted October 21, 2011 Author Share Posted October 21, 2011 Its all working now except the calculation of the totaling of the accumulated score. I'm not sure if I was suppose to pas $score through something specific or what, But thank you very much for the help you have provided and I will look for better learning resources.
