在sql中插入錯誤

Question

我想在數據庫中插入2個值，我想給每個$ userid一個$ teamid，以便用戶連接到一個團隊。

但是每當我運行它，我都不會在數據庫中看到它。

<?php 
if(isset($_POST['submit'])) 

{ 
$db = mysql_connect("localhost","root","usbw"); 
mysql_select_db("the red socks",$db) or die ("fout: openen db mislukt"); 

$userid = $_POST['userid']; 
$teamid = $_POST['teamid']; 

$query = "INSERT INTO team_users (userid, teamid,) VALUES ('$userid', '$teamid')"; 
echo $query; 
$result = mysql_query($query); 
echo $result; 
} 
else 
{ 
?> 
<form method='post' action=''> 
<table> 
<tr><td>invoegen<br></td></tr> 
<tr><td>User ID</td></tr> 
<tr><td><input name='userid'></td></tr> 
<tr><td>Team ID</td></tr> 
<tr><td><input name='teamid'></td></tr> 
<tr><td><input name='submit' type='submit' value='inloggen'> 
<input type='reset' name='reset'value='wissen'></td></tr> 
</table> 
</form> 
<?php 
} 
?> 

回波餘從查詢得到當我在teamid鍵入7成用戶ID和2：

INSERT INTO team_users（用戶ID，teamid，）VALUES（ '7'， '2'）

Answer 1

改變這種

$query ="INSERT INTO team_users (userid, teamid,) VALUES ('$userid','$teamid')"; 
               ^----remove the , here 

到

$query ="INSERT INTO team_users (userid, teamid) VALUES ('$userid', '$teamid')";
