Current Time Stamp - php

Question

I have read many of the postings regarding current time stamp and tried many of the solutions provided, however none of them fixed my issue. I need a current time stamp to be added to the database. I think my code may be the reason why the other solutions are not working. Everything else post perfectly. The time stamp just gives me all "0", the other solutions I tried gave me a "line 6 error".
Here is my current code
<?php
$con = mysql_connect("mysql","username","password");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
/* Prevent duplicate submissions */
if (isset($_COOKIE['FormSubmitted']))
{
show_error('You may only submit this form once per session!');
}
mysql_select_db("seller", $con);
$sql="INSERT INTO listing (name, email, website, url, dropdown, price, date, visitors, income, host, description)
VALUES
('$_POST[name]', '$_POST[email]', '$_POST[website]', '$_POST[url]', '$_POST [dropdown]', '$_POST[price]', '$_POST[date]','$_POST[visitors]', '$_POST[income]', '$_POST[host]', '$_POST[description]', 'CURRENT_TIMESTAMP[subdate]' )";
if (!mysql_query($sql,$con))
{
die('Error: ' . mysql_error());
}
echo "Thank you for listing with us. Explore Now";
mysql_close($con)
?>

Using CURRENT_TIMESTAMP in the PHP context has no sense!
You have to include the needed default value in your table definition.
Something like this:
CREATE TABLE listing
...
description VARCHAR(...)
creation_date TIMESTAMP DEFAULT CURRENT_TIMESTAMP
...
Then in PHP you should only write:
$sql="
INSERT INTO listing (name, ..., description)
VALUES ('$_POST[name]', ..., '$_POST[description]')
";
