I want to get the selected value from my combo box and save in mysql database. I dont even no how to begin, I've managed to create the combo box. Here is my code:

<?
include("dbinfo.inc.php");

class ComboBox
{
var $tableName;
var $databaseName;


/* Begin Edit Constructor */

function ComboBox( $tblname, $dbname )
{
$tableName = $tblname;
$database = $dbname;


/* Connect to database */
mysql_connect('127.0.0.1',$username,$password);
@mysql_select_db($database) or die( "Unable to select database");
$para_query=mysql_query("select * from $tableName") or die(mysql_error());


/* Begin result table */
echo("<table width=100>");
echo("<select size=\"1\" name=\"id\">");
while ($row = mysql_fetch_array($para_query))
{
/* Output combo box */
echo("<option value=");
echo( $row[ 0 ] );
echo(">");
echo( $row[ 0 ] );
echo("</option>");
}

echo("</select>");
echo("</table>");

}// End Constructor

}// End Edit

?>

You need to enclose your <select> fields in a form and POST it to another script to process (or POST it back to itself and do it all in the same script). Are you familiar with HTML forms?

I'm new to both HTML and PHP. I've spend the whole of yesterday searching for a solution. I'l be glad if you can assist. I know I'm left with that part that allows me to retrieve the selected value.

Thank you in advance
[code]//HTML Form
<form name='data_collect' action='process.php' method='POST'>
    Pick a number:
    <select name='number'>
        <option value='0'>0</option>
        <option value='1'>1</option>
        <option value='2'>2</option>
    </select>
    <input type='submit' name='submit' value='Go!'/>
</form>

//PHP Processing script
<?php
$number = $_POST['number'];
echo "The number you selected was: $number";
?>[/code]

Thanx a lot. I will try to modify my script using this one as a guide. My list box is a dynamic one as you might have seen.
