Button clicks

[feck]

Hi,Is there a way to have a simple page that post a variable back too itself and display that varaible on the page.Using a button to increment a variable and then redisplay the new value

Do you mean something like this?

<?phpif(isset($_POST['submit'])) {echo "Your name is $_POST[name]<br />and your email is <a href='mailto:$_POST[email]'>$_POST[email]</a>";}else {echo "<form action='' method='post'><p>Name<br /><input type='text' name='name' /></p><p>Email<br /><input type='text' name='email' /></p><p> <br /><input type='submit' name='submit' value='Submit' /></p></form>";}?>

I tested the code, and it works. It's very similiar to the one in the PHP section at W3Schools, just that I made this on my own right now

Sorry andersmoen,what I'm thinking of is something that will diplay the amount of times you click a button, by posting a variable back to itself after every click and redisplay the new value.I not too sure this can be done without using javascript, maybe I'm wrong.

Aha. Maybe you mean the count() variable in PHP. Read about it at php.net.

Solved it:

<?phpif(isset($_POST['count'])){		$var=++$_POST['count'];	}else{		$var= '1';	}echo "<form action='testButtonClick.php' method='post'><p>Counter:<br /><input type='text' name='count' value='$var'/></p><br /><input type='submit' name='submit' value='Submit' /></p></form>";?>

Pretty useless piece of code, I know, but just wanted too see how it could be done.Is there no other way of doing this apart from a full page refresh?

[Anders Moen]

Hmm, I guess there are. You can use <form action='' method='post'>. Then you will be on the same site all the time. If that's what you mean.

The testButtonClick.php was the script itself, did'nt know you could leave this out and achieve the same thing in the post method. Thanks for that, but both way's still require a full refresh.

[Anders Moen]

Okay, you could have told us in the post before you know :)I guess you'll gonna have to find something else than the count() then. Search for ip counter at google.com or something. Maybe you'll get something then

If you don't want to refresh your page like the F5 way.. you can take a look at AJAX (Google some tuts & W3Schools tuts offcourse)
