Question

I have the following code:

function GetSetting($key)
{
    $Result = mysql_query("SELECT * FROM settings WHERE keys='$key'") or die(mysql_error());
    while($Row = mysql_fetch_array($Result))
    {
        return $Row['value'];
    }
    return false;
}

But I get the following error:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘keys=’header_title” at line 1

What is wrong with my SQL query?

Answer 1

keys is a reserved word, so you’ll have to escape it:

SELECT ... WHERE `keys`='$key';
                 ^----^--

In other words, your query actually isn’t good, and MySQL was telling you exactly where the problem was…
