用十进制更新MySQL记录

Question

I can not figure out how to update the record with aa decimal. For example. For room width, I need to add 4.2 but it rounds to 4. Please help

if ((isset($_POST["MM_update"])) && ($_POST["MM_update"] == $form_number)) {
$updateSQL = sprintf("UPDATE pano_table817 SET room_name=%s, room_width=%s, 
room_length=%s, delete_image=%s, is_pano=%s, outside_image=%s, 
floor_level=%s 
WHERE pano_id=%s",
                   GetSQLValueString($_POST['room_name'], "text"),
                   GetSQLValueString($_POST['room_width'],"numeric"),
                    GetSQLValueString($_POST['room_length'],"numeric"),
                    GetSQLValueString($_POST['delete_image'],"int"),
                    GetSQLValueString($_POST['is_pano'],"int"),
                    GetSQLValueString($_POST['outside_image'],"int"),
                    GetSQLValueString($_POST['floor_level'],"int"),
                   GetSQLValueString($_POST['pano_id'], "int")); 
mysql_select_db($database_ndctour, $ndctour);
$Result1 = mysql_query($updateSQL, $ndctour) or die(mysql_error());

HTML Form:

<input type="text" name="room_width" class="input-text-integer" value="<?php 
echo $row_uploaded_images['room_width']?>">ft</td><td>
<input type="text" name="room_length" class="input-text-integer" value="<?
php echo $row_uploaded_images['room_length']?>">ft</td><td>

Answer 1

check your field definition for room_width, it needs to accept decimals with (in your case, with this specific example in mind) at least 1 decimal, and 2 total numbers. This would give you

DECIMAL(2,1)

give yourself a little room, and use something along the lines of

DECIMAL(4,2)

if you did have a valid mysql definition, let me know and ill look more in depth
