Checkbox Help

baldtrainer

I am working with forms (specifically , checkboxes) and am running into an issue that I can't figure out for the life of me.

Here's the code for the forms...

  <input type="checkbox" name="questions[]" value="1" /> 1989<br />
  <input type="checkbox" name="questions[]" value="0"  /> 1991<br />
  <input type="checkbox" name="questions[]" value ="1" /> 1990 <br />
  <input type="checkbox" name="questions[]" value ="1" /> 2004</p>

As you can see, there are 3 correct answers (value is '1') and 1 incorrect answer.

Here is the php code...

<?php
$questions = $_POST["questions"];

if(is_array($questions))
{
echo 'Great Job!';	
}
else
{
echo 'Nada';	
}

?>

Here's my issue. If the user clicks on any of the correct answers (but not all of them), they get positive feedback. Further, even if they click on the wrong answer (but click 1 or all of the correct answers), they get positive feedback.

Is it possible to check the value of each form in the array and have that be what is checked in the conditional statement?

I know I can do this without an array, but I'm trying to stay away from writing thousands of if/else statements.

Thanks so much for your help!!!

Im not sure I understand your question correctly, but ...

No checkboxes checked => $_POST["questions"] = NULL
One or more boxes checked => $_POST["questions"] is an array containing values of checked boxes, in order, but since all correct values are 1, then you won't know which answer was correct.

<?php
if(isset($_POST["questions"])){
	$incorrect = in_array('0', $_POST["questions"]);
	$correct = in_array('1', $_POST["questions"]);
	$mixed =  $incorrect && $correct;
}
?>

Hope that helps.

Have an array at the start of your script a bit like:

$totals = array('questions'=>3, 'questions2'=>2,);  // etc

Then loop through all the $_POST['questions'] values and just add them together. If the total for each group isn't equal to the value in that initial array, then the user has answered the question wrongly.
