Need help!!! Please
I am new to PHP so please bear with me.
I have a page that I display several questions retrieving from the DB along with its answers. I do not have any problems displayed them. Each question have 4 checkboxes. Users can check as many boxes as it applied. After users submit the form, I need to compare their answers with the correct answers for each question. How do I get their answer from each question to compare. I used $_POST to get their answers, but i get an array of all the checkboxes which does not help me to compare for each answer.
Here is my code:
<input type='checkbox' name='option[]' value='a'>
<input type='checkbox' name='option[]' value='b'>
<input type='checkbox' name='option[]' value='c'>
<input type='checkbox' name='option[]' value='d'>
each answer is a checkbox. User can check as many checkboxes as they want.
1 .question1......?
a. answer1
b. answer2
c. answer3
d. answer4
User chose d and a
Correct answer is a and b
2 .question2......
a. answer1
b. answer2
c. answer3
d. answer4
User chose a and b.
Correct answer is c.
$boxes=$_POST['option'];
echo("<p>You selected answer(s): ");
foreach ($boxes as $key) {echo "Key: $key";}
The correct answer of each question is hidden from user.
thank you
