The only int variable won't _POST - php

Question

And I again I have to deal with PHP and MySQL :) So, I've got a mysql table and want to have "add" feature. So I can edit my table from browser easily. So far I have done nearly everything but the problem is that variable consisting "number" from my table (or id) won't _POST to other page. It won't _POST directly from textarea or even if I put it in a hidden field(well, have just understood that this is pretty much the same).
Let me show you some examples:
$a = mysql_query("SELECT number FROM peoples ORDER BY number DESC LIMIT 1");
$number_a = mysql_fetch_assoc($a);
$number = $number_a['number']+1;`
That's how I got this variable.
echo '<input name="id" type="hidden" value="'.$number.'" />';
That's how I pass it.
echo $number = mysql_escape_string( $_POST['id'] );
That's how I tried to get it in other php file.
Everything from other textareas passes just fine.
Full code as requested. ADD.PHP:

$dblocation = "127.0.0.1";
$dbname = "tvp";
$dbuser = "root";
$dbpasswd = "";

if (!$dbcnx)
{
echo( "<P>В настоящий момент сервер базы данных не доступен, поэтому
корректное отображение страницы невозможно.</P>" );
exit();
}
if (!#mysql_select_db($dbname, $dbcnx))
{
echo( "<P>В настоящий момент база данных не доступна, поэтому
корректное отображение страницы невозможно.</P>" );
exit();

$a = mysql_query("SELECT number FROM peoples ORDER BY number DESC LIMIT 1");

Thanks in advance!

Answer 1

first things first. make sure you are echoing out the number to the screen. the code you have written looks correct but it's just a snippet.
add var_dump($number) after you assign your number and see if it's showing the number. if it's not then theres a problem with your sql

Answer 2

the problem is your re-assigning the hidden field id at the bottom of your form
here
echo '<td><textarea name="city">'.$man['city'].'</textarea></td>';
echo '</tr>';
echo '<input name="id" type="hidden" value="'.$id.'" />'; <------- HERE
echo '<input name="statee" type="hidden" value="'.$man['state'].'" />';
echo '<tr>';
echo '<td>Штат</td>';
i'm assuming you never assigned $id to number so, at the top of your form, yours assigning the hidden field id to "$number" but at the bottom of the form your assigning the hidden field id to $id. overwriting the original id field from the top of the form

Answer 3

You are echoing!
echo $number = mysql_escape_string( $_POST['id'] );
Change that with:
$number = mysql_escape_string( $_POST['id'] );
echo $number;
If you wanna echo it.
