Iframe help (yikes) everything works perfect in firefox but not IE or Chrome

[lowlowz]

Here is the scenario:

 

I have phpbb installed inside of an iframe and I have all of these features working .....in firefox only:

Iframe re-sizes to fit content

external links within the forum open in a new window

traffic to my /forum directory is redirected (with a javascript window.location.replace) to open inside of the iframe

 

Essentially phpbb works perfectly in firefox

 

When I load it in either Chrome or IE:

My site index will load fine (as will any site feature that is not within the iframe)

When I attempt to load my forum or request anything within the iframe IE and Chrome show the page for less than one second then continuously load a 404 page within the frame

 

This leads me to believe that it is a problem with my redirect...but I have no clue.

 

Here is the PHP, hopefully somebody can help:

 

Iframe re-size code (in iframefile.php):

 

<script type="text/javascript">

/***********************************************
* IFrame SSI script II- &#169; Dynamic Drive DHTML code library (http://www.dynamicdrive.com)
* Visit DynamicDrive.com for hundreds of original DHTML scripts
* This notice must stay intact for legal use
***********************************************/

//Input the IDs of the IFRAMES you wish to dynamically resize to match its content height:
//Separate each ID with a comma. Examples: ["myframe1", "myframe2"] or ["myframe"] or [] for none:
var iframeids=["myframe"]

//Should script hide iframe from browsers that don't support this script (non IE5+/NS6+ browsers. Recommended):
var iframehide="yes"

var getFFVersion=navigator.userAgent.substring(navigator.userAgent.indexOf("Firefox")).split("/")[1]
var FFextraHeight=parseFloat(getFFVersion)>=0.1? 150 : 0 //extra height in px to add to iframe in FireFox 1.0+ browsers

function resizeCaller(){
var dyniframe=new Array()
for (i=0; i<iframeids.length; i++){
if (document.getElementById)
resizeIframe(iframeids[i])
//reveal iframe for lower end browsers? (see var above):
if ((document.all || document.getElementById) && iframehide=="no"){
var tempobj=document.all? document.all[iframeids[i]] : document.getElementById(iframeids[i])
tempobj.style.display="block"
}
}
}

function resizeIframe(frameid){
var currentfr=document.getElementById(frameid)
if (currentfr && !window.opera){
currentfr.style.display="block"
if (currentfr.contentDocument && currentfr.contentDocument.body.offsetHeight) //ns6 syntax
currentfr.height = currentfr.contentDocument.body.offsetHeight+FFextraHeight; 
else if (currentfr.Document && currentfr.Document.body.scrollHeight) //ie5+ syntax
currentfr.height = currentfr.Document.body.scrollHeight;
if (currentfr.addEventListener)
currentfr.addEventListener("load", readjustIframe, false)
else if (currentfr.attachEvent){
currentfr.detachEvent("onload", readjustIframe) // Bug fix line
currentfr.attachEvent("onload", readjustIframe)
}
}
}

function readjustIframe(loadevt) {
var crossevt=(window.event)? event : loadevt
var iframeroot=(crossevt.currentTarget)? crossevt.currentTarget : crossevt.srcElement
if (iframeroot)
resizeIframe(iframeroot.id);
}

function loadintoIframe(iframeid, url){
if (document.getElementById)
document.getElementById(iframeid).src=url
}

if (window.addEventListener)
window.addEventListener("load", resizeCaller, false)
else if (window.attachEvent)
window.attachEvent("onload", resizeCaller)
else
window.onload=resizeCaller

</script>

____________________________________________________

 

This is (part of) the javascript redirect (in iframefile.php)

 

<script type="text/javascript">
var text = window.location.href;
function delineate(str) {
theleft = str.indexOf("=") + 1;
theright = str.indexOf("&");
return(str.substring(theleft, str.length));
}
url=delineate(text)

function refreshFrame() {
myframe.location.replace("http://www.mydomain/?var1='+window.location.href+'");
}
</script>

 

This is the other part of the above javascript redirect that is in the overall_header to redirect pages requested within the forum to target the iframe via the code above:

 

<script type="text/javascript">
if (window == top) {
var url='window.location.replace("/?var1='+window.location.href+'")';
eval(url);
}
</script>

 

 

This is the necessary code i had to add in my home directory index.php for the above two codes to work:

 

<?
ob_start();
$vary = $_GET['var1'];
$tee = $_GET['t'];
if ( $vary == "" ) {
// do nothing, no var
} else {
$gogogo = strtolower($vary);
$healthy = array("http://mydomain/forum/", "http://www.mydomain/forum/");
$yummy   = array("", "");
$newphrase = str_replace($healthy, $yummy, $gogogo);

$finalcode = base64_encode($newphrase);
$healthy = array("+", "=");
$yummy   = array("7PLUS7", "7EQUALS7");
$newphraseu = str_replace($healthy, $yummy, $finalcode);
if ( $tee == "" ) {
header("Location: http://www.mydomain/iframefile.php?var=$newphraseu");
} else {
header("Location: http://www.mydomain/iframefile.php?var=$newphraseu&t=$tee");
}
}
ob_flush();
?>

___________________________________

 

And finally this is the code for my actual iframe (in iframefile.php):

 

<?
$healthy = array("7PLUS7", "7EQUALS7");
$yummy   = array("+", "=");
$newphraseu = str_replace($healthy, $yummy, $vary);

$finally = base64_decode($newphraseu);
if ( $tee == "" ) {
$thedone = $finally;
} else {
$thedone = "$finally&t=$tee";
}
if ( $vary == "" ) {
?>
<center><iframe onload="refreshFrame();" id="myframe" src="/forum" scrolling="no" marginwidth="0" frameborder="0" marginheight="0" vspace="0" hspace="0" style="overflow:invisible; width:100%; display:none"></iframe></center>
<?
} else {
?>
<center><iframe onload="refreshFrame();" id="myframe" src="/forum/<? echo $thedone; ?>" scrolling="no" marginwidth="0" marginheight="0" frameborder="0" vspace="0" hspace="0" style="overflow:invisible; width:100%; display:none"></iframe></center>
<?
}
?>

 

 

Sorry for the long read.

Again this all works perfect in firefox but with IE and Chrome the iframe keeps reloading a 404 page after showing the requested page briefly.

Any and all help is appreciated!

 

Thanks in advance

Sorry, I should include my url for this....  http://www.razzleberry.info    Notice how the Downloads and Forum tabs work in firefox vs. IE or Chrome. Thx again

Even in firefox i just had the 404 error from hostgator.

I am running IE7 (because my expensive HP printer will not work with IE8 and there is no fix for it) and it displays just fine.

[lowlowz]

I think I have it working in (hopefully) all browsers now...

Using latest firefox, seems to work.
