I’m trying to edit an item in a mySQL database generated list. Here is the code:

<?php
// contact to database
$connect = mysql_connect("<HOST>", "<USER>", "<PASSWORD>") or die ("Error , check your server connection.");
mysql_select_db("tvc");
?>

<html>
<head>
<title></title>
</head>

<body>

<?php 
$result = mysql_query("UPDATE closet SET
    pattern = '{$_POST['pattern']}'
    WHERE id='{$_POST['id']}'") or die ("Error in query");

// if successfully updated. 
if($result){
echo "Successful";
echo "<BR>";
echo "<a href='patterns.php'>Back to Patterns List</a>";
}

else {
echo "ERROR";
}

?>

</body>
</html>

I get an ‘error in query’ error message and I can’t figure out what is causing it.

Any help would be much appreciated!

    You forgot to remove , before WHERE

    Change

    $result = mysql_query("UPDATE closet SET
    pattern = '{$_POST['pattern']}',
    WHERE id='{$_POST['id']}'") or die ("Error in query");

    To

    $pattern = mysql_real_escape_string($_POST['pattern']);
$id= mysql_real_escape_string($_POST['id']);

$result = mysql_query("UPDATE closet SET
    pattern = '".$pattern."' WHERE id='".$id."'") or
die("Could not connect: " . mysql_error());

    2.Mysql extension is not recommended for writing new code. Instead, either the mysqli or PDO_MySQL extension should be used. More reading: PHP Manual
