处理多种表格和打印内容[关闭]

Hi I have an issue with the desired output of the following code. I need to print You hit T-- message whilst I see the Form 2 is here! message along with the button.

But now what happens is when I click T-- button the message appears but the Form 2 is here content with button disappears. I need that message to be on the screen visible whilst the message You hit T-- prints.

can some one pls highlight how to correct this? Many thanks for looking

here goes the code:

<DOCTYPE html>
<html>
    <head>
        <title></title>
    </head>
    <body>
        <div id="one" style="width:300px; background:gray;">
            <form method="post" action="<?= $_SERVER['PHP_SELF'] ?>">
                <input type="text" name="txt1" id="txt1">
                <?php
                if(isset($_POST['sendone']))
                {echo "<input type='submit' name='sendtwo' id='sendtwo' value='Two'>";}
                ?>
                <input type="submit" name="sendone" id="sendone" value="One">
            </form>
        </div>

        <div id="two" style="width:300px; background:yellow;">
            <?php
            if(isset($_POST['sendtwo']))
            {echo "Form two is here!"; ?>
            <form method="post" action="<?= $_SERVER['PHP_SELF'] ?>">
                <?php echo "<input type='submit' name='sendt' id='sendt' value='T--'>";}

                if(isset($_POST['sendt'])) {echo "You hit T--"; return;}
                ?>
            </form>
        </div>
    </body>
</html>

If i got this right, is basically print that message when you post ether sendtwo or sendt.

if(isset($_POST['sendtwo']) || isset($_POST['sendt']))
{ echo "Form two is here!"; ?> }

Here's an example.
