How to get value of an input box into php? is it possible? syntax?

[Matt Brown - identify]

Hello,


My goal is to make an input check box that saves an input text to a
cookie when checked and destroys the cookie when unchecked.
I figured i could use the onclick method of the input box to execute
the PHP function setcookie, but how do I get the value from the input
text? Testing with the window.alert function, inputtextName.v alue
doesn't work in the PHP:

<html>
Your name:
<input class="selectst yle" type="checkbox" name="savename"
onclick='window .alert("savenam e.value")'><br>

<input class="inputsty le2" type="text" name="name" value="<?php echo
$_COOKIE["name"]; ?>">

literally "savename.value " is alerted.

I need the cookie value to echo.


Help is appreciated,

Matt

Matt,

I don't understand quite what you're trying to do - but you can't call a
PHP function from an onclick() message. The PHP code is executed on the
server before the page ever gets sent to the client.

You could use AJAX to call back to the server - but it seems like an
awful lot of trouble. Whatever you're trying to accomplish, there must
be better ways of doing it.
