Passing $_POST data with postfield (was: Hi...desperately need help)

hello there,
i just started doing some programming in wml. actually, iv almost completed some work on a web site, and right now im just converting it to wml. im getting problems with $_POST, i never actually get the values. in one of them, when im executing a query, instead of having a value( i tried to print it to check) i only get the variable names.

im posting one bmi checker, it doesnt need any database tables. im getting a division by zero error, maybe because i didnt pass the variables well...could you have a look at it? thanks a lott,
yuk****a

well, that wasnt me using s word, thats just my name,
sunyukta...

Hi sunyukta, welcome to Devshed.

I think it may be failing because you are printing out the second card
before the form has been posted....

You could try something like:

Also note that you WML output is invalid and will break on a real phone.

hi , thanks...
im getting problems with $_POST[]...when im using postfield, say for a numeric field, when im using them in a query, im only getting the field name...

im posting some of my code
<?php
$conn_clinic = mysql_pconnect("localhost", "clinic", "") or trigger_error(mysql_error(),E_USER_ERROR);


mysql_select_db($database_conn_clinic, $conn_clinic);
$query_rsdept = "SELECT departments.Departmentno, departments.Departmentname FROM departments";
$rsdept = mysql_query($query_rsdept, $conn_clinic) or die(mysql_error());
$row_rsdept = mysql_fetch_assoc($rsdept);
$totalRows_rsdept = mysql_num_rows($rsdept);

function quote_smart($value)
{
// Stripslashes

if ( get_magic_quotes_gpc() )

{

$value = stripslashes( $value );

}

// Quote if not a number or a numeric string

if ( !is_numeric( $value ) )

{

$value = "'" . mysql_real_escape_string($value) . "'";

}

return $value;

iv used a recordset which prints all the options for departments, it's supposed to print details about staff when i click on search.
