loop on my quiz id and get each one and inserted in the answer table

Question

I need to get the question id and insert it into the answer table every time the $qid insert into the database 1

this is my db table look like

┌──┬───┬─────┬───┬────────┐
│id│uid│ad_id│qid│answer  │
├──┼───┼─────┼───┼────────┤
│1 │2  │15   │1  │Answer 1│
├──┼───┼─────┼───┼────────┤
│2 │2  │15   │1  │Answer 2│
├──┼───┼─────┼───┼────────┤
│3 │2  │15   │1  │Answer 3│
├──┼───┼─────┼───┼────────┤
│4 │2  │15   │1  │Answer 4│
└──┴───┴─────┴───┴────────┘

now the column qid should be the question id coming from the question table but it dose not as you see it's always insert 1

this is my PHP code

<form action="<?php $_SERVER['PHP_SELF'] ?>" method="post" id="quiz" class="container width_648">

<?php
            $getTheQuiz = $db->prepare("SELECT * FROM rec_employer_quiz WHERE ad_id=?");
            $getTheQuiz->bind_param('i', $ad);
            if ($getTheQuiz->execute()) {
                $res = $getTheQuiz->get_result();
                $i = 0;
                while ($q = $res->fetch_array()) {
                    ?>
                    <div class="oneLine">
                        <div class="question">
                            <h3><?php printf("%s", $q['question']) ?></h3>
                            <input type="hidden" value="<?php printf("%s", $q['id']) ?>" name="qid" id="qid">
                        </div>
                        <div class="answer">
                            <input type="hidden" name="qid" id="qid" value="<?php printf("%s", $q['id']) ?>">
                            <textarea name="answer[]" rows="3" maxlength="200" class="message1 width_640"></textarea>
                        </div>
                    </div>
                <?php
                }
                ?>
                <div class=" oneLine">
                    <input type="submit" name="ans" id="ans" value="I'm Finished" class=" MainBtn">
                </div>

                <?php
                $dateApplied = date(date_default_timezone_get());
                if (isset($_POST['ans'])) {
                    //$questionId=$_POST['qid'];
                    foreach ($_POST["answer"] as $key => $answer) {
                        $questionId=$_POST['qid'];
                        $answer = $_POST["answer"][$key];
                        $putData = $db->prepare("INSERT INTO rec_employer_quiz_results (id, uid, ad_id, qid, answer, exam_date)VALUE(?, ?, ?, ?, ?, FROM_UNIXTIME(?))");
                        $putData->bind_param('iiiiss', $id, $uid, $ad, $questionId, $answer, $dateApplied);
                        if ($putData->execute()) {
                            echo "done";
                        } else {
                            printf("Error: %s\n", $db->error);
                        }
                    }
                }
            }
            ?>
        </form>

What I am getting now is the last question id for all the answers I need to insert the id of the question with it's value.

I am getting this on print_r($_POST);

1

but when check the inserted qid in my database it just insert 1 for all the rows.

Answer 1

Let's consider your code here:

<div class="question">
    <input type="hidden" value="<?php printf("%s", $q['id']) ?>" name="qid" id="qid">
 </div>
 <div class="answer">
    <input type="hidden" name="qid" id="qid" value="<?php printf("%s", $q['id']) ?>">
    <textarea name="answer[]" rows="3" maxlength="200" class="message1 width_640"></textarea>
</div>

Here you already have 2 fields with name qid. After you post all fields from your form the last qid value will be saved. Also I don't understand why do you need 2 qid fields for each question? One field is not enough?

What you need to do is to set qid as answer, i.e

<input type="hidden" name="qid[]" id="qid" value="<?php printf("%s", $q['id']) ?>">

Print_r you $_POST values then and see how are they arranged.

Going further you can use current $q['id'] as part of field name:

<input type="hidden" name="qid[<?php printf("%s", $q['id']) ?>]" id="qid" value="<?php printf("%s", $q['id']) ?>">

And for answer too:

<textarea name="answer[<?php printf("%s", $q['id']) ?>]" rows="3" maxlength="200" class="message1 width_640"></textarea>

Again print_r you $_POST values then and see how are they arranged.

Sidenote: id attribute for fields should be unique for each field.

Update: so, I see you get proper qids. You should now use the same keys from qid and answer:

foreach ($_POST["answer"] as $key => $answer) {
    $answer = $_POST["answer"][$key];
    $questionId = $_POST['qid'][$key];
    // do insert
}
