Php mysql update puts in blank space

Question

Okay, so i have a problem here. I solved the updating to a mysql database with just set values. But now i want to let the user put something by use of a textbox to update a row. this doesnt seem to work

code:

$newfirstname = $_POST['newfirstname'];

        //Update the record
        $updateQuery = "UPDATE users SET firstname = '".$newfirstname."' WHERE KcID = 2";
        mysql_query($updateQuery) or die("Error: ".mysql_error());
        //create the query
        $query = mysql_query("select * from voskousers");

        //return the array and loop through each row
        while ($row = mysql_fetch_array($query))
        {
    ?>

It just doesnt update it with the right value, it makes it a blank space in my row.

Answer 1

是因为您要更新一个名为users的表，然后从一个名为voskousers的表中进行选择吗？
