Update SQL data within PHP - php

Question

Ok i have updated my Code, not getting any Errors but nothing is being updated on the mysql side nor on the PHP Front end.
I have even tried a Hard Coded Statment.
This section is at the Very top of my Php Viewer page..
<?php
/
/ IF RESQUEST IS EQUAL TO SUBMUIT
if (isset($_REQUEST['submit']))
{
$my_date = date("Y-m-d H:i:s");
$order = uniqid();
$FullName= $_REQUEST['fullname'];
//Take in full Name and Split it into first and last name.
list($fname, $lname ) = explode( ' ', $customerName, 2 );
$address = $_REQUEST['address'];
$emailAddress = $_REQUEST['emailAddress'];
$phoneNo = $_REQUEST['phoneNo'];
Below is my Sticky Forum which is getting the Information from the Database and putting it into the Text Fields
// STICKY FORM TO ALLOW USER TO UPDATE INFORMATION
if (isset($_REQUEST['up']))
{
$query_sticky = mysqli_query($connection,'SELECT * FROM orders WHERE id = "' . $_GET['id'] . '"');
if(! $query_sticky )
{
die('Could not get data: ' . mysqli_error($connection)); // Could not find Order_id show Error
}//end die error
else
(isset($_REQUEST['update']));
{
while($row = mysqli_fetch_array($query_sticky, MYSQLI_ASSOC))
{
$row['id'];
echo '<form action="" method="post">'
Name:';
echo'<input name="customerName" id="cname" type="text" required value="'.$row['firstname']. " " .$row['lastname']. '" />';
echo' <br/>
<br/>
Address:
<textarea name="address" id = "caddress" type="text" rows="5" cols="30" required value="'.$row['address'].'" ></textarea>
<br/>
<br/>
Email Address:
<input name="emailAddress" type="email" required value="'.$row['email']. '" />
<br/>
<br/>
<br/>
Phone Number:
<input name="phoneNo" id="phoneNumber" type="text" required value="'.$row['phone']. '" />
<br/>
<br/>
<button type="submit" name="update" value="update" >update</button
<div id="Submit">
</form>
<form action="order.php" method="delete">
</form>';
}//close if
}
} // Close While
here is my Update Section
if (isset($_REQUEST['update']))
{
$updateDB = "UPDATE orders SET student ='$_POST[student]',
firstname='John', lastname='wallace',
email = '$_POST[emailAddress]', address = '$_POST[address]',
phone = '$_POST[phoneNo]'
WHERE
order_id ='$_GET[order_id]'";
mysqli_query($connection, $updateDB);
}//end update..
}//end PHP
?>

Answer 1

You were mixing up single and double quotes in your UPDATE query string. Try this instead:
$updateDB = "UPDATE test
SET email = '".#$_POST[$emailAddress]."',
address = '".#$_POST[$address]."',
phone = '".#$_POST[$phoneNo]."'
WHERE id = '".$_GET['id']."'";
