Isset wont recognize the submit on POST PHP

Question

if (isset($_POST['submit'])) in the following code wont execute, same goes for the if(isset($_POST['Q1']))

<form action='' onsubmit="return validateQuiz()" method="post">
            <section>
                <p>Who cares?</p>
                <input type="radio" name="Q1" value="Q1_1">
                <label for="Q1_1">Me?</label><br>
                <input type="radio" name="Q1" value="Q1_2">
                <label for="Q1_2">No one</label><br>
                <input type="radio" name="Q1" value="Q1_3">
                <label for="Q1_3">That guy</label>
            </section>

            <br>
            <input id="submit" type="submit" value="submit" name="submit">
        </form>

In the same file there goes a php block right under this form that goes:

<?php

        if (isset($_POST['submit'])) {
            if(isset($_POST['Q1']))
            {
                echo "You have selected :" . $_POST['Q1'];  //  Displaying selected value not working
            }
        }
        ?>

For further information, I've tried doing pure if (isset($_POST['submit'])) to see what the real problem was, and it doesn't even set the isset to true even tho the form was submitteed. I've also tried the GET method instead of POST, still doesnt work. Pure echo-code without anything else works so php is working as intended.

Here is a picture of how it looks if anyone is wondering and such, Right under submit should appear text of what was selected.

I realized that name is an important part of the post checker, Ive added a name value for the submit button but it still doesnt work? — Hymandois, Mar 07 '23 at 17:12
When you say "nothing" do you mean **nothing** or do you mean `array(0) { }`? — Quentin, Mar 07 '23 at 17:26
as in array(0) { }, I did 'echo var_dump($_POST);' for your information — Hymandois, Mar 07 '23 at 17:27
So you aren't sending a POST. Does `validateQuiz` do form processing? — user3783243, Mar 07 '23 at 17:27
Then the most likely explanation is that the function `validateQuiz` is doing something to break it. Remove `onsubmit="return validateQuiz()"`. — Quentin, Mar 07 '23 at 17:27
Ah yup, it was the problem, thanks for helping @Quentin & user3783243 — Hymandois, Mar 07 '23 at 17:30
