Executing a PHP function in HTML

zang1

Here's what I'm trying to do, I have a page with a button on it, and I want to execute a PHP function when the button is clicked. This is what I have and it doesn't seem to be working. When I click the button I get an error "Object Expected"

<SCRIPT LANGUAGE="PHP">
function my_function() {
$host = "192.168.0.6";
$port = "70";
$timeout = "60";
$fp = fsockopen($host, $port, &$errno, &$errstr, $timeout);
}
</SCRIPT>

Now I know why this isn't working because when the page is being loaded its not picking up the PHP. How can I do this so when I click the button, it executes the function but does NOT reload the page.

Any help would be greatly apreciated.

Thanks,
Zang

What you've coded here doesn't make any sense. You're writing code in PHP, which is supposed to be executed server-side to build a complete HTML page. Then you're asking Javascript, which is a client-side scripting language, to call a PHP function by name. It can't. Not only are they completely separate languages, but the client does not ever receive or execute PHP code.

I know that doesn't work, I have no idea how to make it work, I was using that to show what I am TRYING to do.

This should do what you need. It's not "client-side PHP", but close. basically you are reloading the page with a varible function name call. If you needed to keep the values of other varibles you could just pass them also.

Hope it helps.

<?php
if(isset($action))
{
$action();
}

function my_function()
{
$host = "192.168.0.6";
$port = "70";
$timeout = "60";
$fp = fsockopen($host, $port, &$errno, &$errstr, $timeout);
}
?>

<CENTER><input type="button" value="GO!" onclick="location.href='<?php echo
$PHP_SELF; ?>?action=my_function'"></CENTER>

Also you may want to add some security by encoding the passed function name and limiting the functions that can be executed by $action.

Just some thoughts after I hit submit,

you're mixing javascript style scripting (client side) with php style scripting (server side).

consider changing the button to a submit in a form. have php call the function my_function() when the page refreshes after the submit.
