How to make a poll out of voting?

Question

PHP

Hello dear experts.
Please do not kick me hard, I'm just learning.
There is a voting script, counts, displays the results, and so on. everything is great. fastened an adaptive layout to it, an admin panel with authorization and user registration. everything seems to be not bad. but I would like to modify it a little, but I don’t have enough mind (before kicking, please note that I’m just learning).
Now it goes like this:
I create a vote, it contains answers 1,2,3 or 10 answers and so on.
How can I make the same poll / vote be created, but there were several votes, preferably an unlimited number. For example, I clicked a button, a new question with answer options was added. it turns out, for example, Poll No. 1
There, question No. 1
is option "a"
- option "b"
- option "c"
There is question number 2
- option "a"
- option "b"
- option "c"
Here is the structure of the tables and the code itself when you create a new vote.
Thanks in advance to everyone who helped, I was already desperate (although apparently there is a task to work with relationships between tables or even rows. My head is boiling, confused)

<?php
include_once "config.php"; # подключаем файл с настройками
db_connect(); # подключаемся к базе
# если кнопка НЕ нажата, то выводим форму
if (!isset($_POST['submit'])) {
?>
    <form action="" method="POST">
        Введите ваш вопрос
        <input type="text" name="quest" placeholder="Текст Вашего вопроса" class="form-control">
        <br/>
        Варианты ответа (1 строчка - 1 вариант)<br/>
      <textarea class="form-control" rows="5" id="textareaDefault" name="variant"></textarea>
      <br/>
        <div class="col-lg-6">
                            
                            
                        </div>
                      
      <input type="submit" name="submit" value="Добавить" class="btn btn-primary"/>
    </form>
    <br/>
                    </div>
<?php
}
else { # если кнопка нажата, то заносим в базу опрос
    $err = array();
    $quest = mysql_real_escape_string($_POST['quest']);
    $variant = mysql_real_escape_string($_POST['variant']);
 
# Проверяем заполнено ли поле для ввода вопроса 
    if (trim($quest) == '') {
        $err[] = "Вы не задали вопрос";
    }
# Проверяем введены ли варианты ответа
    if (trim($variant) == '') {
      $err[] = "Вы не ввели варианты ответа";
    }
    else {
# Разделяем строки и засовываем их в массив
      $variant= explode('\r\n', $variant);
        if (count($variant) < 2) {
            $err[] = "Вариантов ответа должно быть минимум 2!";
        }
    }
# Проверяем нет ли уже такого вопроса в базе
    $quest_query = mysql_query("SELECT count(*) FROM `poll_question` WHERE quest_name = '".$quest."'") or die(mysql_query());
    $count = mysql_result($quest_query,0,0);
    if ($count > 0 ) $err[] = "Такой вопрос уже есть в базе, задайте другой";
    unset($quest_query);
  
# Проверяем были ли ошибки, если ошибки были выводим их
    if (count($err) != 0) {
        echo "<b>Ошибки:</b><br/>";
        foreach ($err as $error) echo $error."<br/>";
        echo "<br><a href=\"javascript:history.go(-1);\">Вернуться назад</a>";
    }
# Если ошибок небыло заносим данные в базу
    else {
# Записываем вопрос в базу
        $q = mysql_query("INSERT INTO `poll_question` SET quest_name = '".$quest."', quest_act = 1") or die (mysql_error());
      unset($q);
# Узнаем ID только что записанного вопроса
        $q = mysql_query("SELECT * FROM `poll_question` WHERE quest_name = '".$quest."'") or die(mysql_error());
        $row = mysql_fetch_array($q);
        $id_quest = $row['quest_id'];
        unset($q,$row);
#Записываем в базу варианты ответа
        foreach ($variant as $var)
            $q = mysql_query("INSERT INTO `poll_variant` SET var_id_quest = ".$id_quest.", var_name = '".$var."', var_voice = 0") or die(mysql_error());
        
        echo 'Опрос успешно добавлен!<br/>';
        echo '<a href="/journal.php">Добавить еще?</a>';		
    }
}
?>

Here is the table structure:
poll_question and poll_variant tables
poll_question - table with questions

CREATE TABLE `poll_question` (
  `quest_id` int(5) NOT NULL auto_increment,
  `quest_name` varchar(255) NOT NULL,
  `quest_act` int(1) NOT NULL,
  PRIMARY KEY  (`quest_id`)
);

quest_id - 1,2,3,4..., N is set automatically
quest_name - The question itself
quest_act - if 1, then display the poll, if 0, then remove it.
poll_variant - table with answer options

CREATE TABLE `poll_variant` (
  `var_id` int(5) NOT NULL auto_increment,
  `var_id_quest` int(5) NOT NULL,
  `var_name` varchar(255) NOT NULL,
  `var_voice` int(4) NOT NULL,
  PRIMARY KEY  (`var_id`)
);

var_id - 1,2,3,4..., N is set automatically
var_id_quest - Determine the belonging to the question (the ID of the question to which the answer belongs)
var_name - The answer itself
var_voice - How many people voted
