Php check if in iframe

Check if site is inside iframe

PHP is never in an iframe. PHP is executed on the server side and generates output such as HTML, Javascript, or text. The output generated by PHP may produce or reside within an iframe, but never PHP itself.

ADDITIONAL DETAIL

With regard to the additional detail you added in comments (that you want to distinguish between requests directly to your site and requests via a Facebook application) there are a few techniques you can use:

You can check the referrer to determine if a request came from a Facebook URL, from another page on your own site, from a third-party site, or if it was direct traffic. This method is not foolproof, but may provide more information than your application currently receives.

You can create separate URLs for the application running on your site and the Facebook version. Using $_SERVER[‘REQUEST_URI’] , you can easily detect whether your application was accessed via ‘yoursite.com/fbapp’ or ‘yoursite.com/localapp’. Both URLs can reference the same scripts via Apache’s mod_rewrite or the aliasing solution of your choice.

This method is possibly the easiest to implement. If you can provide URL parameters when you provide an application URL to Facebook, just add a parameter. For example:

In PHP, you can easily check for the existence and value of the access_method parameter, and take action as necessary.

For anyone who lands on this old thread: There is a very easy way to check in PHP wether or not your page is loaded through an iframe.

if( isset($_SERVER['HTTP_SEC_FETCH_DEST']) && $_SERVER['HTTP_SEC_FETCH_DEST'] == 'iframe' ) <> 

No, PHP is server side. It has no way of knowing if it is in a iframe.

Check If Site Is Inside Iframe

How to identify if a webpage is being loaded inside an iframe or directly into the browser window?

Browsers can block access to window.top due to same origin policy. IE bugs also take place. Here’s the working code:

function inIframe () try return window.self !== window.top; 
> catch (e) return true; 
>
>

top and self are both window objects (along with parent ), so you’re seeing if your window is the top window.

Foolproof way to detect if this page is INSIDE a cross-domain iframe

First check if you are IFramed.

If you are IFramed, then your referrer is your parent frame url.

From this url you should be able to detect if you want to branch your code.

Detect iFrame embedding in Javascript

Looking at frame length breaks down generally if page A itself has frames (I know this might not be the case for this specific instance). The more reliable and meaningful test would be:

PHP: Check if page is displayed inside iframe?

Php cannot tell the context for which the request is made. It doesn’t know anything except what is passed to it and available as server variable. You could add your own get parameter to the url to be used when putting your page in an iframe, but otherwise you are out of luck.

I know it’s possible with javascript, but i couldn’t find any example with PHP?

Detect if page is viewed inside an iframe in PHP

I have a blog service and I’m trying to prevent people from displaying the blogs on their own domains with an iframe.

I have added this code in my .htaccess :

Header always append X-Frame-Options SAMEORIGIN Copy code

But I found out that even though modern browsers do not display the page’s content, the PHP script is still executing, as proven by adding this piece of code at the end of the script :

$file = fopen("test.txt","w"); fwrite($file,"script loaded"); Copy code

Is there any way to detect that the page is being loaded in an iframe from PHP and stop the script’s execution in the first place ?

Answer

Solution:

There’s no way to detect if the content is being framed from a PHP script, you can only serve an X-Frame-Options header as you did to prevent the content being displayed by the browser.

This is often used as a security measure to prevent attacks such as clickjacking.
