Hi. I'm no expert here, and I need some help.
This form does not update the database. I know it is accessing the database because the checkbox and radio buttons variables are good, but there is no result posted.
Can anyone tell me what is wrong here.

<?php
session_start(); 

// Place Session variable 'recid' into local variable
	$recid 		 = $_SESSION['recid'];
	$username    = $_SESSION['name'];
	$school    = $_SESSION['college'];
//Connect to the database
include_once "demo_conn.php";
// Query members data from the database and organise it for display
$sql = mysql_query("SELECT group1, group2, group3, group4, group5, group6 FROM members WHERE recid='$recid' LIMIT 1");
while($row = mysql_fetch_array($sql)){
$group1 = $row['group1'];
$group2 = $row['group2'];
$group3 = $row['group3'];
$group4 = $row['group4'];
$group5 = $row['group5'];
$group6 = $row['group6'];
}

// Process the form 
if ($_POST['group']) {
    $userGroup = $_POST['group'];
	
	foreach($_POST['snames'] as $x) {
		mysql_query("UPDATE users SET userGroup='$userGroup' WHERE recid='$recid' AND userId='$x'");
	}
    echo 'Selected students have been updated to new groups.<br /><br />

if ($_POST) {
$userGroup = $_POST;
foreach($_POST as $x) {
mysql_query("UPDATE users SET userGroup='$userGroup' WHERE recid='$recid' AND userId='$x'");
}
echo 'Selected students have been updated to new groups.<br /><br />

shouldn't $userGroup=$_POST be array too? If so, i think you should specify what field to process in query:

"UPDATE users SET userGroup='$userGroup[]' WHERE recid='$recid' AND userId='$x'"

Thanks for your comment, but the page didn't like that at all. It just returned a white screen.

I suppose that $_POST has more than one value (array). If so, you should use some loop and save values in new array (or use the same $_POST), and in query get that values by $userGroup[0] or something like that.
I'm at the similar level of knowledge as you are, so don't take my notes as an expert solution.

EDIT: sorry, just saw that its radio button, no array than

'group' is a radio button, but 'snames' is an array of indeterminate length, because it lists all the students in a particular classroom, which of course, will change from time to time.
I think you might be a bit further along than me though.

I mean, I have an array of checkboxes, but a set list of radio buttons.
