I tried this code, I don't know why it shows some errors.

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '1' at line 1

and how to do, when it runs sucessfull and automaticality return to $_REQUEST['do'] == "add" ???

PHP Code:

// ### ADD ###
if ($_REQUEST['do'] == "add")
{
echo     "<table border=\"1\" align=\"center\">
    <tr>
        <td><form action=\"$PHP_SELF?do=adding\" method=\"post\">
        Title:<br/> <small>Example: American Pie 4</small></td>
        <td><input type=\"text\" name=\"title\" value=\"Title\" onfocus=\"if (this.value == 'Title') this.value = '';\"/></td>
    </tr>
        <tr>
        <td>If you're done, click Send!
        <td><input type=\"submit\" value=\"Send\"/></form></td>
    </tr>
</table>

";
}

// ### START ADDING ###
if ($_REQUEST['do'] == "adding")
{
        $adding = $db->query("
        INSERT INTO test (title) 
        VALUES ('$_POST[title]')
        ");
}
