Update query not updating records - php

Question

I am totally confused as to why my update query is not updating the records. There are no errors in inspector console. If I run the query in phpmyadmin substituting the vars with actual values it works fine.
I have tried coding the vars like this in query: '".$name."' and also like i have it now. All field names are correct and all values are being passed to php correctly. I would be grateful if someone could point out my error as it is driving me nuts. Many thanks
<?php
$conn = mysqli_connect("localhost","root","","domain");
if($conn === false) {
die("ERROR: Could not connect. " . mysqli_connect_error());
}
$id = mysqli_real_escape_string($conn, $_POST['idcon']);
$company = mysqli_real_escape_string($conn, $_POST['companycon']);
$name = mysqli_real_escape_string($conn, $_POST['namecon']);
$email = mysqli_real_escape_string($conn, $_POST['emailcon']);
$phone = mysqli_real_escape_string($conn, _POST['phonecon']);
$fax = mysqli_real_escape_string($conn, $_POST['faxcon']);
$mobile = mysqli_real_escape_string($conn, $_POST['mobilecon']);
$sql = mysqli_query($conn, "UPDATE contact_con SET idcode_con = '$company', name_con = '$name', email_con = '$email', phone_con = '$phone', fax_con = '$fax', mobile_con = '$mobile' WHERE id_con='$id'");
mysqli_close($conn);
?>

You should be using prepared queries, also you have a typo _POST['phonecon'].
<?php
$conn = mysqli_connect("localhost", "root", "", "domain");
// check connection
if (mysqli_connect_errno()) {
exit("Connect failed: ". mysqli_connect_error());
}
// create a prepared statement
$stmt = $conn->prepare("
UPDATE contact_con
SET idcode_con = ?,
name_con = ?,
email_con = ?,
phone_con = ?,
fax_con = ?,
mobile_con = ?
WHERE id_con= ?
");
if ($stmt) {
// bind parameters for markers
$stmt->bind_param(
"ssssssi",
$_POST['companycon'],
$_POST['namecon'],
$_POST['emailcon'],
$_POST['phonecon'],
$_POST['faxcon'],
$_POST['mobilecon'],
$_POST['idcon']
);
// execute query
$stmt->execute();
// close statement
$stmt->close();
}
// close connection
$conn->close();
?>
