将所选单选按钮与表格中的字段进行比较

Question

How do I check the selected radio button value with the value stored in a database field? Code is below:

index.php:

    dfdfdffdfdfdfdf

question.php

$_POST['answer'];
$totalCorrect = 0;

if ($_POST == 'CorrectAnswer') { $totalCorrect++;}

echo "$totalCorrect questions correct";

I want to pass the answer chosen to check it with the database to see if it matches the value of CorrectAnswer and edit the score accordingly.

Answer 1

You missed to access the 'answer' index when accessing $_POST. Use:

if ($_POST['answer'] == 'CorrectAnswer') { $totalCorrect++;}

instead.
