Form handling with PHP

I have a bunch of pages with long forms, with lots of input
types-text, radios, textareas, and the debugging process has become
overwhelming.
What I need to happen is to make sure that
1. Every field on the page is filled out-if not, a list of incorrect
fields is displayed, and any radio boxes that were checked still are
2. The fields are queried to a table in a database. (The table has the
same column names as the field names)

Here's what I did; can someone tell me why this doesn't work?

<?php
require_once ('../mysql_connect.php');
$page_title = 'Test page';

if (isset($_POST['submit'])) { // Handle the form.

// Create an empty new variable.
$message = NULL;

// Create a function for escaping the data.
function escape_data ($data) {
global $dbc; // Need the connection.
if (ini_get('magic_quotes_gpc')) {
$data = stripslashes($data);
}
return mysql_real_escape_string($data, $dbc);
}

//Create an array of all formfield names
$required=array('field1','field2','field3');

//Check to see if all field names are filled in
function field_check($required) {
foreach($required as $q) {
if(empty($_POST[$q])) {
$message = 'Error: The following field was not filled in: $q';
$ok=FALSE;
}
else {
$ok;
}
}
}

// If no empty posts are returned
if ($ok) {
//set a variable for the current user
$u = addslashes($_COOKIE['user_id']);

//insert all variable values into the table
foreach($required as $q) {
$query = "INSERT INTO test_table ($q) VALUES ('$'.'$q')";
}

// Run the query
$result = @mysql_query ($query); // Run the query.

// If it ran OK, write the the page with a link to continue.
if ($result) {
include ('templates/header.inc');
$page_title = 'Entry Recorded';
echo "<p><b><a href=\"next_page.php\"
class=\"content\">Continue</a>";
include ('templates/footer.inc');
exit(); // Quit the script.
}
// If it did not run OK, show an error
else {
$message = '<p>Your form could not be recorded due to a system
error. We apologize for any inconvenience.</p><p>' . mysql_error() .
'</p>';
}
}

// Close the database connection
mysql_close($dbc);
}

include ('templates/header.inc');

// Print the error message if there is one.
if (isset($message)) {
echo '<font color="red">', $message, '</font>';
}

// Print the page.
?>

<form action="<? echo $_SERVER['PHP_SELF']; ?>" method="post">
<table>
<tr>
<td><input type="radio" name="field1" value="1"</td>
<td><input type="radio" name="field1" value="2"></td>
<td><input type="text" name="field2"></td>
<td><textarea name="field3" rows="20" cols="30">
</textarea></td>
</tr>
</table>
<p>
<input type="submit" name="submit" value="Add to Record">
</p>
</form>
<?
include ('templates/footer.inc'); // Include the HTML footer.
?>
Thanks.

It doesn't work because it isn't coded properly...
What bit doesn't work?

You may want to try this class instead of reinventing the wheel. It can
compose and validate HTML forms, either on client side with Javascript
or on the server side with the class code. It supports many common
validation types.

You can compose the forms output with a Smarty plugin that makes it
possible to integrate with the class. The generated output embeds the
necessary Javascript but you do not need to know Javascript at all.
