'PHP send variable value external webpage

I'm currently trying to send the two variable values, $incorrect and $correct from a form.

I have tried to use $_POST[] to create this functionality, yet it doesn't work!

Could anyone help me when creating such a functionality ?

page1.php

<form action="testresult.php" method="POST">
    <label for="qn1">Question 1: <?php echo $array_question[$question_num_array[0]] ?></label><br>
    <input type="text" id="question1_answer" name="question1_answer" required><br><br>
    
    <label for="qn2">Question 2: <?php echo $array_question[$question_num_array[1]] ?></label><br>
    <input type="text" id="question2_answer" name="question2_answer" required><br><br>

    <label for="qn3">Question 3: <?php echo $array_question[$question_num_array[2]] ?></label><br>
    <input type="text" id="question3_answer" name="question3_answer" required><br><br>

    <input type="hidden" name="correct" id="correct" value="<?php $correct ?>" />
    <input type="hidden" name="incorrect" id="incorrect" value="<?php $incorrect ?>" />
    
    <input type="submit" name="submitAnswers" value="Submit">
</form>

<?php
        if(isset($_POST["submitAnswers"])){
            $correct = 0;
            $incorrect = 0;
            $qn1_ans = $_POST['question1_answer'];
            $qn2_ans = $_POST['question2_answer'];
            $qn3_ans = $_POST['question3_answer'];

            if ($qn1_ans == $array_answer[$question_num_array[0]]){ $correct ++; }
            else { $incorrect ++; }

            if ($qn2_ans == $array_answer[$question_num_array[1]]){ $correct ++; }
            else { $incorrect ++; }

            if ($qn3_ans == $array_answer[$question_num_array[2]]){ $correct ++; }
            else { $incorrect ++; }

        }
    ?>

And on the receiving end page2.php

<html>
    <head>
    <title>Results</title>
    </head>
    <body>
        <?php
        $correct = $_POST['correct'];
        $incorrect = $_POST['incorrect'];

        echo $correct."test ".$incorrect;
        ?>
    </body>
</html>

php html

Your first page should JUST show the questions, it will be like this.

<form action="testresult.php" method="POST">
    <label for="qn1">Question 1: <?php echo $array_question[$question_num_array[0]] ?></label><br>
    <input type="text" id="question1_answer" name="question1_answer" required><br><br>
    
    <label for="qn2">Question 2: <?php echo $array_question[$question_num_array[1]] ?></label><br>
    <input type="text" id="question2_answer" name="question2_answer" required><br><br>

    <label for="qn3">Question 3: <?php echo $array_question[$question_num_array[2]] ?></label><br>
    <input type="text" id="question3_answer" name="question3_answer" required><br><br>

    <!--input type="hidden" name="correct" id="correct" value="<?php $correct ?>" />
    <input type="hidden" name="incorrect" id="incorrect" value="<?php $incorrect ?>" /-->
    
    <input type="submit" name="submitAnswers" value="Submit">
</form>

When you hit the submit button, the answers are posted to testresult.php.

In this file, first checking the answers, then showing the result.

The page doesn't contain questions, so you need to include the php file too.

<html>
    <head>
    <title>Results</title>
    </head>
    <body>
        <?php
        if(isset($_POST["submitAnswers"])){
            include 'question.php'; #include the question array.

            $correct = 0;
            $incorrect = 0;
            $qn1_ans = $_POST['question1_answer'];
            $qn2_ans = $_POST['question2_answer'];
            $qn3_ans = $_POST['question3_answer'];

            if ($qn1_ans == $array_answer[$question_num_array[0]]){ $correct ++; }
            else { $incorrect ++; }

            if ($qn2_ans == $array_answer[$question_num_array[1]]){ $correct ++; }
            else { $incorrect ++; }

            if ($qn3_ans == $array_answer[$question_num_array[2]]){ $correct ++; }
            else { $incorrect ++; }

            echo $correct."test ".$incorrect;
        }
        ?>
    </body>
</html>

Where did those variables from from?

In your code you're calling two vars $array_answer and $question_num_array.

None of these two variables are set! Please fix this issue.

The Form action you've set to your testresult.php. So surely the form will carry all of its data to that page. But you are trying to get the data on the same page as if(isset($_POST["submitAnswers"])) where is the form; what actually should exist in that testresult.php page. So should be like this:

index.php or something.php

<form action="testresult.php" method="POST">
    <label for="qn1">Question 1: <?php echo $array_question[$question_num_array[0]] ?></label><br>
    <input type="text" id="question1_answer" name="question1_answer" required><br><br>
    
    <label for="qn2">Question 2: <?php echo $array_question[$question_num_array[1]] ?></label><br>
    <input type="text" id="question2_answer" name="question2_answer" required><br><br>

    <label for="qn3">Question 3: <?php echo $array_question[$question_num_array[2]] ?></label><br>
    <input type="text" id="question3_answer" name="question3_answer" required><br><br>

    <input type="hidden" name="correct" id="correct" value="<?php $correct ?>" />
    <input type="hidden" name="incorrect" id="incorrect" value="<?php $incorrect ?>" />
    
    <input type="submit" name="submitAnswers" value="Submit">
</form>

testresult.php

<?php



// questions array that is called in the form's page should be 
   called here too to get the questions and comparisons.

    if (isset($_POST['submitAnswers'])) {
    $correct = 0;
    $incorrect = 0;
    $qn1_ans = $_POST['question1_answer'];
    $qn2_ans = $_POST['question2_answer'];
    $qn3_ans = $_POST['question3_answer'];

    if ($qn1_ans == $array_answer[$question_num_array[0]]) {
        $correct++;
    } else {
        $incorrect++;
    }

    if ($qn2_ans == $array_answer[$question_num_array[1]]) {
        $correct++;
    } else {
        $incorrect++;
    }

    if ($qn3_ans == $array_answer[$question_num_array[2]]) {
        $correct++;
    } else {
        $incorrect++;
    }
}
?>
<html>

<head>
    <title>Results</title>
</head>

<body>
    <?php
    $correct = $_POST['correct'];
    $incorrect = $_POST['incorrect'];
    
    echo $correct . 'test ' . $incorrect;
    ?>
</body>

</html>
