I want to ask the user questions by using a form. I have a text field where the user inputs either 1 or 2 and then they press submit. I can get this to work but I need to keep asking them questions based off there last answer to the previus question.
I am making a game where you start with a number ex 5 and then you either choose to take away 1 or two from that number. so we take away 2 now the number is 3 and then the computer has his go using the same number. He chooses to take away 1 which makes the number 2. Now we take away 2 and win the game for being the first one to get the number down to 0. Its a very simple game that im trying to do just to brush up on my php skills.
my code so far....
<p> please enter a number to begin the subtraction game</p>
<form name="submit1" method="post">
<input type="text" name="startingNumber">
<input type="submit" name='submit1'>
</form>
<?php if (!empty($_POST['startingNumber'])) {?>
<p>your starting number is: <?php echo $_POST['startingNumber']?></p>
<?php
while(!$_POST['startingNumber'] == 0){?>
<p> Would you like to minus one or two from <?php echo $_POST['startingNumber'];
?></p>
<form name="submit2" method="post">
<input type="text" name="oneOrTwo">
<input type="submit" name='submit2'>
</form>
<?php } }?>
As you can see i am no where near close to getting this right. Im thinking i have to use a while loop to keep asking the question minus 1 or 2 until they reach 0. Inside this while loop im thinking i need something like a waituntil user has clicked submit.
In fact i have written the same game in c++ so if it helps here is that. (it works just how i want it too)
the problem im having is that in c++ you can use cin to get a input from the user and it waits until the user types in a value but im struggling to find anything like that in php.
Any help would be greatly appreciated thank you.
#include <cstdlib>
#include <iostream>
using namespace std;
int main(int argc, char *argv[])
{ int number, oneOrTwo, remainder;
cout << "please enter a number to begin the subtraction game";
cin >> number;
while (number != 0){
cout <<"your turn, subtract 1 or 2 from " << number << endl;
cin >> oneOrTwo;
if (oneOrTwo == 1 || oneOrTwo == 2){
number = number - oneOrTwo;
}else{
cout << "sorry you have entered a incorrect number. Please enter either 1 or 2" << endl;
continue;
}
if (number == 0){
cout << "congratulations! you won the game";
break;
}
remainder = number % 3;
if (remainder % 3 == 0){
remainder = 2;
}
cout << "now my turn im going to subtract " << remainder << " from " << number << endl;
number = number - remainder;
if (number == 0){
cout << "sorry the computer won this time";
}
}
system("PAUSE");
return EXIT_SUCCESS;
}
