将JavaScript确认框的结果分配给PHP变量

Question

//this is in php
function msgbox($msg, $type)
    {
    if ($type == "alert")
        {
        // Simple alert window
        ?> <script language="JavaScript"> alert("<? echo $msg; ?>"); </script> <?
        }
    elseif ($type == "confirm")
        {
        // Enter Confirm Code Here and assign the $result variable for use
        // Should include "OK" and "Cancel" buttons.
        ?>
           <script language="JavaScript">
           if (confirm("<? echo $msg; ?>"))
                {
                <? $result == "ok"; ?>
                }
           else
                {
                <? $result == "cancel"; ?>
                }
           </script>
        <?
        }
    }



if ($page_title->exists())

{msgbox("page exists,do you want to delete", "confirm");

}      
 if ($result == "ok")
//code..

The problem is that $result is not reading the value from the confirm box I think because the if clause is not being executed and the program flow is going where it would go without the if clause.

You are using short tags, make sure that they are turned on from php.ini file otherwise php code won't execute in your code.
