Call PHP function in HTML

[xbuilder]

Hello,

Is there is a way to call a PHP function rather than a cgi script as in the following example. The ok_cancel() JavaScript function prompts the user to click for OK or Cancel. Only when the user clicked OK, I want to call a PHP function, such as myfn(), rather than calling a PHP script.

<?php

echo '<a href="my.php" onclick="return ok_cancel()"> text</a>';

?>

Thanks a lot.

Hi,
the better way is to reload the page when user click ok with the parameter in url.

Else you can make a frame with width 0, put a php script here that call function and put result in a jscript variable...

see you

Thanks but I am only a few days into web development and PHP and could not do what your suggested.

All I wanted was ask the user to confirm before a php function is called.

BRING UP A WINDOW
IF USER CLICKED OK
{
my_php_function();
}

You can't absolutely. PHP is executed on the server, jscritp on the client.

You can do this:

BRING UP A WINDOW
IF USER CLICKED OK
{
document.location.replace(document.location+"?exec=my_php_function");
}

This will reload your page with $exec variable.
At begin of page you can now put:
if($exec=="my_php_function")my_php_function();

or something like this.

The reason that I need to call a a function rather than a PHP script is that I have a class object to pass to the function. The system administrator has disabled the session function of the PHP server. I do not want the class object to get lost when calling another script or the current script for a second time.

Also I have to use the cgi version of PHP due to the admin settings.

abook = new BOOK();
abook->isbn = 11111;
abook->title = ".....:
.....

CONFIRMATION =???? java_script_or_any_popup_win()
/ My difficult is to get the user's choice into a PHP variable /

if (confirmed)
{
add_this_book_to_db($abook);
}

I'm sorry, but you can't.

Serialize object and pass as a variable in url:

abook = new BOOK();
abook->isbn = 11111;
abook->title = ".....:
.....

CONFIRMATION =???? java_script_or_any_popup_win()
/ My difficult is to get the user's choice into a PHP variable /

if (confirmed)
{

document.location.replace(document.location+"?object=<?serialize(abook)?>");

}

Or save it in a file, or in a db, or in a cookie, etc etc...
From client simply you can't call a php function.
