How to call a php function from a swf file

[-:)lauri]

Try with orginal function:

PHP Code:

function logout1(){
    global $logoutAction2;
    $logoutAction2 = $_SERVER['PHP_SELF']."?doLogout=true";
    if ((isset($_SERVER['QUERY_STRING'])) && ($_SERVER['QUERY_STRING'] != "")){
        $logoutAction2 .="&". htmlentities($_SERVER['QUERY_STRING']);
    }
    
    if ((isset($_GET['doLogout'])) &&($_GET['doLogout']=="true")){
        //to fully log out a visitor we need to clear the session varialbles
        $_SESSION['MM_Username'] = NULL;
        $_SESSION['MM_UserGroup'] = NULL;
        $_SESSION['PrevUrl'] = NULL;
        unset($_SESSION['MM_Username']);
        unset($_SESSION['MM_UserGroup']);
        unset($_SESSION['PrevUrl']);
        $logoutGoTo = "../../login.php";
        if ($logoutGoTo) {
            header("Location: $logoutGoTo");
            exit;
        }
    }
} 


...as you can see there is a "header()" and not "return".

Well and there is "exit" too which means you probably should add it in this also:

PHP Code:

<?php 
    if(isset($_POST['logout']))  
    { 
        header("Location: ".$logoutAction2);
    } 
?>

to get

PHP Code:

<?php 
    if(isset($_POST['logout']))  
    { 
        header("Location: ".$logoutAction2);
        exit;
    } 
?>

just every time you're using the header().

Hi

My logout button is now working as required.
Many thanks for your help.

If possible could you add a couple of comments to the following code
just so that I have a better idea what is going on.

{
    post.logout = "laksfslvs";
    var ureq:URLRequest = new URLRequest(fileName);
    ureq.data = post;
    ureq.method = URLRequestMethod.POST;
    navigateToURL( ureq, "_self");
}

Best regards Maxwell

My plan is to add the logout button to multiple files. So I would change this line to

var fileName:String = "../../public/computers/computers.php";

I noticed when I added the same button as previous to a file in the same folder as computers_publicaccess.php called computers.php
the button still worked.

This makes me think that the following line may not be needed

var fileName:String = "../../public/computers/computers_publicaccess.php";

import flash.events.MouseEvent;
import flash.net.URLLoader;


var fileName:String = "../../public/computers/computers_publicaccess.php";

var post:URLVariables = new URLVariables();
logOutBtn.addEventListener(MouseEvent.CLICK, onClick);

function onClick(event:MouseEvent):void
{
    post.logout = "laksfslvs";
    var ureq:URLRequest = new URLRequest(fileName);
    ureq.data = post;
    ureq.method = URLRequestMethod.POST;
    navigateToURL( ureq, "_self");
}

{
    // First we define variable "logout" and give it some value, so
    // it is correctly defined and php can detect that. post is an
    // object of URLVariables
    post.logout = "laksfslvs";

    // Then we define url request object that takes the url as a
    // string
    var ureq:URLRequest = new URLRequest(fileName);

    // We add our URLVariables to our url request object
    ureq.data = post;

    // Then we define the method type that will be used to 
    // transferring data to server and we use POST 
    ureq.method = URLRequestMethod.POST;

    // Finally we just launch a www site with our url request 
    // object. "_self" is optional html tag and while I'm not sure 
    // could user force the page open in some other window 
    // at least this shouldn't open new window and just 
    // refreshes the currentone.
    navigateToURL( ureq, "_self");
}

I'm pretty sure you need url address to post any values to any server from swf object. But then if you have your swf object inside of the <a></a> tags as was your previous button then you wouldn't probably need a single line of any code in your Flash. But I haven't been testing that so much so there may be some other ways to do the job that I'm not aware of.

Anyway if you need to reuse your button, maybe you should give the address to the flash dynamically via flashvars, which you can define at the same time you define the swf object on your html page, which should look with older implementations something like this:

<?php $address = "../../public/computers/computers_publicaccess.php"; ?>
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0" width="550" height="400" title="ReadingFlashVars">
	<param name="movie" value="ReadingFlashVars.swf" />
	<param name="quality" value="high" />
	<param name="FlashVars" value="url=<?php echo $address; ?>" />
	<embed src="ReadingFlashVars.swf" width="550" height="400" quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" FlashVars="url=<?php echo $address; ?>"></embed>
</object>

Then in the actionscript file something like this may work:

import flash.events.MouseEvent;
import flash.net.URLLoader;


var fileName:String = LoaderInfo(this.root.loaderInfo).parameters.url;

var post:URLVariables = new URLVariables();
logOutBtn.addEventListener(MouseEvent.CLICK, onClick);

function onClick(event:MouseEvent):void
{
    post.logout = "laksfslvs";
    var ureq:URLRequest = new URLRequest(fileName);
    ureq.data = post;
    ureq.method = URLRequestMethod.POST;
    navigateToURL( ureq, "_self");
}
