提交表格将不会提交数据到数据库

我一直试图通宵完成这件事，没有任何运气。由于某种原因表单提交，但数据不会发送到数据库。继承人PHP部分提交表格将不会提交数据到数据库

<?php 

mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB"); 
if (isset ($_POST['Submit'])) //If submit is hit 
{ 
    $name = $_POST['name']; 
    $category = $_POST['category']; 
    $class = $_POST['class']; 
    $level = $_POST['level']; 
    $bind = $_POST['bind']; 
    $tier = $_POST['tier']; 
    $trade = $_POST['trade']; 
    $ilvl = $_POST['ilvl']; 
    $amod = $_POST['amod']; 
    $xdmg = $_POST['xdmg']; 
    $description = $_POST['description']; 
    $description2 = $_POST['description2']; 
    $description3 = $_POST['description3']; 
    $sprice = $_POST['sprice']; 
    $bprice = $_POST['bprice']; 
    $percent = $_POST['percent']; 
    $source = $_POST['source']; 
    $tnail = $_POST['tnail']; 
    $result=MYSQL_QUERY("INSERT INTO items (name, category, class, level, bind, tier, trade, ilvl, amod, xdmg, description, description2, description3, sprice, bprice, percent, source, tnail)". 
    "VALUES ('$name', '$category', '$class', '$level', '$bind', '$tier', '$trade', '$ilvl', '$amod', '$xdmg', '$description', '$description2', '$description3', '$sprice', '$bprice', '$percent', '$source', '$tnail')")or die("<p><span style=\"color: red;\">Unable to select table</span></p>"); 
    mysql_close(); 
    //confirm 
    echo "<p><span style=\"color: red;\">Thank You; the items have been entered in the database. DO NOT REFRESH THE PAGE or data will be sent again.</span></p>"; 
} 
else 
{ 
    // close php so we can put in our code 
?>

任何帮助吗？

是您的“MYSQL_QUERY”都在首都？ – 2012-03-25 09:32:18

@WaynnLue表示无所谓。 – Shikiryu 2012-03-25 09:34:23
