Question

I’m doing this one using PHP.

I’m doing some basic quiz application and it has a backend. On my backend, I am setting up a quiz for students to answer. One of my interface is like this.

If the user checked the box, it means 1950 is the answer. How would I process that one in my database to determine that 1950 has been the answer of the question.

My Database is like this.

tbl_choices
Id,Choice,isAnswer

so ideally, it would be stored like this.

tbl_choices
ID         CHOICE      isAnswer
001         1900          0
002         1800          0
003         1950          1
004         1850          0

My question here is how would I code it in a sense when a user will check the checkbox and the textinput right beside it will have a value of isAnswer as 1.

Just an additional info: When a user will click that + button it will add a new textinput and if user will click - button it will delete a textinput, but I got that all covered.

The choices are dynamic, it will changed, that above that I’ve shown you is just an example.

P.S: Sorry for the title, I don’t know what’s the title of this kind of question 🙂

Your help would be greatly appreciated and rewarded!

Answer 1

you can try html like this :

<input type="checkbox" value="1900" name="answer1[]">
<input type="text" value="1900" name="answer2[]" />
<input type="checkbox" value="1800" name="answer1[]">
<input type="text" value="1800" name="answer2[]" />
<input type="checkbox" value="1950" name="answer1[]">
<input type="text" value="1950" name="answer2[]" />
<input type="checkbox" value="1850" name="answer1[]">
<input type="text" value="1850" name="answer2[]" />

and then use php code:

foreach($_POST['answer2'] as $v){


    if(in_array($v, $_POST['answer1'])) {
        $s = 1;
    }else
     $s = 0;
     $sql = "INSERT INTO table VALUES(null, $v, $s)";
}

also on click plus update values of both check box and text field
