Answer 1

You don't have any form. You have a table and table contents do not sent to php.
You must use a form with fields. Each field must have a name.
In below simplest example: method is post so your form content will be in $_POST. In targetpage.php page, try var_dump($_POST) to see the result after you submit the form.
You'll see $_POST is an array with these keys: email, name, submit.
form.php // php page that has the form
<form action="targetpage.php" method="post">
<div class="form-example">
<label for="name">Enter your name: </label>
<input type="text" name="name" id="name" required>
</div>
<div class="form-example">
<label for="email">Enter your email: </label>
<input type="email" name="email" id="email" required>
</div>
<div class="form-example">
<input type="submit" value="Subscribe!">
</div>
</form>
