I've seen sites enable the user to toggle flash enabled versions of their pages on and off. I know this is acomplished by PHP, but I'm not quite sure how to script it or where I can find a script like that.

I have browsed w3schools.com and found this simple switch example:

<?php
switch (2)
{
case 1:
echo "Number 1";
break;
case 2:
echo "Number 2";
break;
case 3:
echo "Number 3";
break;
default:
echo "No number between 1 and 3";
}
?>

If I were to use this in the areas where I plan on injecting Flash or non-Flash elements, how do I feed HTML code into those cases? And how do I get it to toggle?

You can see examples of what I mean at http://www.broadcom.com/ and at http://www.***-kickin.com/

On Broadcom, just click "Turn Flash On" and for ***-Kickin, click the "Turn Flash Off" tab at the bottom. That's the toggle I'm trying to accomplish.

Ok so you have a flash header (flashheader.swf) and an image header (imgheader.gif) and you want to turn flash on or off (off will just display the image). So on the homepage and every page you want flash or image you would put at the top of the page:

PHP Code:

<?php

//if cookie flash is not set then make flash on by default

if (!isset($_COOKIE[flash])) {

$flash = "on";

}

//otherwise retrieve flash on or off from the cookie

else {

$flash = $_COOKIE['flash'];

}

?>

So now here is where you put the code in the html where you want flash to display:

PHP Code:

<?php

//if flash is on echo the flash html code

if ($flash == "on") {

echo '<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,29,0">

<param name="movie" value="flashheader.swf">

<param name="quality" value="high">

<embed src="flashheader.swf" quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash">

</embed>

</object>';

}



//otherwise echo the image html code

else {

echo '<img src="imgheader.gif" border="0">';

}

?>

Ok now we have done this we need to set flash on or off in the following url:

Flash: flash.php?switch=on
Image: flash.php?switch=off

So in your flash you would create a link to go to 'flash.php?switch=on' called 'Turn Flash Off' and in your image html you would create a link to 'flash.php?switch=off' called 'Turn Flash On'.

flash.php:

PHP Code:

<?php



//set cookie on or off

setcookie ('flash', $_GET[switch], time()+31536000);



//then redirect them back home

header("Location: index.php");

?>

The end

Hey Fire,

Thanks for the bang up job on your reply. It answers a lot of my questions, however, after setting up flash.php and linking to it, once I click the href for "flash.php?switch=on", I get the following:

Parse error: syntax error, unexpected T_SWITCH, expecting ']' in flash.php on line 4

Line 4 in this case is:

PHP Code:

setcookie ('flash', $_GET[switch], time()+31536000); 

Any ideas?

[FiRe]

Try:

$cookie = $_GET['switch'];
setcookie ('flash', $cookie, time()+31536000);

FiRe,

That worked! You're a God ****ed genius. Thanks for helping a newbie along.

Now for my final question, is there any way to redirect them back to the page they came from in flash.php, rather than throwing them back to index.php everytime they turn flash on or off?

[FiRe]

yeh instead of:

header("Location: index.php");

try:

header("Location: $_SERVER[HTTP_REFERER]");

glad it all worked out, took me a while to write

[wicichris]

Outstanding! It works. Fire, you truly are a life saver. My fullest thanks to you for spelling it all out for me.
