Grabbing data from two HTML forms from the same page - php

Question

So I've searched through some posts, and I've seen that I can't use a HTML form within another HTML form.
Like:
<form method="post" action="x.php">
<input type="..."/>
<form method="post" action="x.php">
<input type="..."/>
</form>
</form>
Ok, but my problem is that I want to make a different page, which contains HTML code like this:
<?php
if(isset($_GET['vote']) && $_GET['vote']=='yes'){
echo 'vote successfully inserted';
}
# gets the email value from MAIN form
$email = isset($_POST['email'] : $_POST['email'] : NULL;
#grab the infos from bd for the user with that email,
$stmt = $db->prepare('SELECT name,email,vote FROM tbl WHERE email=:e');
$stmt->execute(array(':e'=>$email));
while($row = $stmt->fetch(PDO::FETCH_OBJ)){
if($row->vote == 'no'){ # IF THE USER DIDN'T VOTED, THEN
if(isset($_POST['vote'])){ # IF THE <a> IS PRESSED, UPDATE DB
$sql = "UPDATE tbl SET vote='yes' WHERE email=:e";
$s = $db->prepare($sql);
$s->execute(array(':e'=>$email));
}
}
?>
<table>
<tr>
<td>Name</td>
<td>Email</td>
<td>Address</td>
<td>Vote</td>
</tr>
<tr>
<td><?php echo $row->name;?></td>
<td><?php echo $row->email;?></td>
<td><?php echo $row->address;?></td>
<td>
<form method="POST" action="" id="SECOND">
VOTE!
</form>
</td>
</tr>
</table>
<?php } // end while() ?>
Then, under this <table>, I have another form:
<form action="" method="POST" id="MAIN>
<input type="text" name="email" placeholder="email"><br/>
<input type="submit" value="Login" name="submit"/>
</form>
The project is about a electoral campaign, where a user can 'login' with this email address, and submit his vote.
So,
when the user requests the page, the MAIN form will pop-up, he will fill in his email, and will press submit.
he is redirected to the same page (I'm hiding the MAIN form), and the table will pop-up.
now, the user can select his favorite candidate, and press on the <a> link - his vote will be stored in db, updating the vote field from, initially 'no' to 'yes'.
Now, the prob is that when the <a> link is pressed, the update in the db doesn't take place.

Answer 1

The reason the link doesn't update the database is because the form is not being submitted. Change the to an
<input type="submit" value="VOTE!">
