I have a table called settings, when I would change or enter data into the form it did not change the data in the table. In addition on form an image upload file is not running, There may be the wrong code below.

<div class="maintitle">Site Settings</div>
<?php
$act=isset($_GET['act'])?$_GET['act']:"";

if($act=='sub'){
$name=isset($_POST['site'])?$_POST['site']:"";
$keys=isset($_POST['keywords'])?$_POST['keywords']:"";
$desc=isset($_POST['descrp'])?$_POST['descrp']:"";
$email=isset($_POST['email'])?$_POST['email']:"";
$fbpage=isset($_POST['fbpage'])?$_POST['fbpage']:"";
$twitter=isset($_POST['twitter'])?$_POST['twitter']:"";
$gplus=isset($_POST['gplus'])?$_POST['gplus']:"";
$disclaimer=isset($_POST['disclaimer'])?$_POST['disclaimer']:"";
$template=isset($_POST['template'])?$_POST['template']:"";


mysql_query("UPDATE settings SET site='$name',keywords='$keys',descrp='$desc',email='$email',fbpage='$fbpage',twitter='$twitter',gplus='$gplus',disclaimer='$disclaimer',template='$template' WHERE id=1");

if($_FILES["file"]["name"]!=''){
           move_uploaded_file($_FILES["file"]["tmp_name"], "../images/logo.png");
    }?>

<div class="infomsgbox">Settings updated successfully.</div>  

<?php }

$q=mysql_query("select * from settings where id=1");
$s=mysql_fetch_assoc($q);
?>
