如何在不移动到PHP的下一页的情况下提交表单

Question

The Problem

I am trying to submit a form in php but due to the nature of what i want i need the page to not go onto the next one i just want it to submit the data and refresh the current page or whatever, at current it submits the data and goes onto page 2 which i dont want i just need it to submit the data and stay on the current page, if thats possible!

The Code

//page 1 code

<center>
<h1>What Is Jacob Dailey Doing?</h1>


<form method="post" action="jacob_dailey.php">

    <select name="baby_status">
        <option value="playing">Playing</option>
        <option value="awake">Awake</option>
        <option value="sleeping">Sleeping</option>
    </select>


<br />
    <input type="submit" value="Submit"/>
</form>

</center>

//page 2 code

<?php
if (isset($_POST['baby_status'])) {
    $baby = $_POST['baby_status'];
    setcookie("baby_status", $baby, time() + 31556926, '/'); //  Data will Store For 1 Year
    header('Location: ' . $_SERVER['PHP_SELF']);
}
$status = $_COOKIE['baby_status'];
echo '<center> <h1>Baby Jacob Dailey Is Currently ' . ucwords($status) . '</h1>';
if ($status == "playing") {
    echo '<img src="http://cdn.sheknows.com/articles/2013/02/baby-playing-with-blocks.jpg"/>';
}
elseif ($status == "awake") {
    echo '<img src="http://www.westheimphoto.com/lightbox/gallery/TaiwanStockPhotos/TWNhw1221.jpg"/>';
}
elseif ($status == "sleeping") {
    echo '<img src="http://www.babycare.onlymyhealth.com/imported/images/neonatal/2012/July/19_Jul_2012/6-Months-Old-ssl.jpg"/>';
}
echo '</center>';
?>

Page 2 code shouldnt be as important but i just need it so when i click submit on page 1 it updates the information on page 2 but doesnt take me to page 2.

Cheers!

Your form can submit onto itself. Just in the action="xyz" either leave it (the whole action=... attribute) out entirely or else name the page that also contains the form there between quotes.

Then when you load the page you check the $_POST or $_GET array (depending on the method) to see if the submit button was pushed or if someone just navigated to the page. (You'll want to give you submit button a name="foo".)
