File Direct Access Disable

[Jick]

I have my site (http://kd7pyo.infinitypages.com/) and on it you will notice that I have a Iframe. The links on the page open up in the Iframe. I wundered if there was a php script that would not allow direct access of the files. The links are Home, About Us, Examples, etc... If you were to go to http://kd7pyo.infinitypages.com/examples.php you could access that page without going to it through the Iframe. I want to make it so if they try to access the page directally it will redirect them to the main index page. I want it so the only way you can access the pages such as examples.php is through the Iframe. Is this possible?

This is a rather old thread, but it might help you along. I've got to leave soon, or I'd try to get you something a bit closer to what you need...

Well since Pyro's gonna be gone can someone else help me?

I am very new to both PHP and JavaScript so I can't give syntax specifics, but here are two solutions that may work.

When the user clicks on a link call a JavaScript function that writes a cookie with name="mylink" value="1". On the page you want loaded into the IFrame set up a selection like so:

$access=$_COOKIE['mylink'];
if ($access==1) {
//print your page
} else {
//redirect to homepage
echo '
<script language=javascript>
window.location.href="www.mysite.com/";
</script>'
}


Alternatively, you could pass the value via a query string.

Also, you may be able to use JavaScript on the pages to be loaded into the IFrame to see if a parent node for the IFrame exists, then use

document.body.innerHTML="myhtml";

However, this method is only good if the pages are to contain no server-side scripts.

I haven't actually tried either of these, so I'm not sure they work.

Sorry I can't provide more actual code, but maybe the above will give you some ideas.

Here it is in psuedo-code:

1: Check if the current page is equal to the main page (ie. the page that contains your iframe.) A simple comparison with $_SERVER["PHP_SELF"] should be enough.

2: If the page is NOT equal to the top page, use a header redirect ( header("Location:http://www.yourdomain.com/yourpage.php?page=$_SERVER['PHP_SELF']"); ) to send it back to the page to the main page with a query string attached.

3: On yourpage.php check if a query string is set ( if(isset(_GET["page"])) { )

4: If it is, set up the frameset with the page in the query string set as the src of the iframe, if not, set it up with the default page...

what if, on the main page, you simply give the iframe page a variable, like send the page as page.php?id=1...so if its not loaded in the iframe, it gets loaded without that variable...

then set up some if statements:

if($id == 1){

// display page

} else {

header(Location: index.php);

}

that should work, should it not?

Yeah, and I thought about that, but decided to give the other version. If you are interested in that way, this might help you: http://www.infinitypages.com/research/divinclude.php

Sorry, I kinda got lost. Will you show me the code all put togeather. I see the diffewrent peices you posted and I tried to put them togeather but I screwed that up. Just post the code and explain what pages the codes go on. Thanks. :D
