Is there any way to mask URLs with PHP or something else? I want to use a custom domain with goo.gl, basically I want to be able to send someone to http://l.bearce.me/iS7tz and have them reidrect to http://goo.gl/iS7tz automatically.
I swear I've seen something like this before, but I can't remember the name of it.
You mean this? (URL cloaking, plain HTML with onclick event)
Google
Or this? (HTTP redirect)
<?php
// get $path form the url (I suppose you're using mod_rewrite or similar)
$path = $_GET['some_url_var'];
header("location: http://goo.gl/$path"); // redirect
?>

I do not care about people viewing my source code, however, I want Bots to avoid coming on to my site and getting through my security. I was hoping to disable page source viewing. To do this, I am using this code:
$url= $_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
$needle = "view-source:";
if (strpos($url,$needle)) { echo "You can not see me";}
else {
//The rest of my index page
}
The objective here is that if someone tries to view my page source or if a bot tries to, that rather than being able to see it, the code will detect that the page URL is view-source:www.yoururl.com and will display a "Nice try" message in the source instead of the page source. The code above in theory should have worked, but didn't. Any other idea's to try and make this work?
This cannot be done, the HTML source code is passed to whoever requests it. You should probably redesign your captcha, as it is not secure from how you described it. Use session variables to store the data and to check against the submitted value on the form processor script.
you could use mod_rewrite and a permanent 301 redirect in your .htaccess to hide the ?captcha=xxxx part of your url, if it is your sole concern.
Im new to this and im trying to rewrite URL so that utm_expid is hidden so if my url is:
http://www.myweb.com/?utm_expid=67183125-2
how would i make it so when user visits
myweb.com
it does not show utm_expid in url
Is this possible using PHP/JS?
NOTE: i cant use RUBY or any other languages except PHP/JS/HTML
There is a way. Just redirect the page to base url once the utm_expid=67183125-2 is got. ie,
if($_GET['utm_expid']) { //header to redirect to myweb.com }
Its a tricky way. Hope you are permitted to use it.
Just start a session and store value in session variable. you can regain it even page is re directed.
ie
<?php
session_start();
if($_GET['utm_expid']) {
$_SESSION['variable_name']=$_GET['utm_expid']
//header to redirect to myweb.com
}
?>
Let me add this Javascript trick that is server agnostic.
if (location.search.indexOf('utm_expid') > -1) {
history.replaceState('page', 'Title', '/')
}
I recommend you to place it at the end of the body.
If you wanted a clean URL (as you do for branding and manual sharing purposes), I'd script it so that you load a full page iFrame which loads the gA test queried URL. That way the user see s the clean URL in the address bar and still see the experiment.
You could use PHP to set up your index page (or any server side, or even client side script).
I would like to create a single URL that returns one image when loaded in a page within my domain, and another slightly modified image when loaded in a page outside my domain.
I am thinking along the lines of something like:
<?php
header('Content-type: image/jpg');
if (/**image is loaded within my domain**/)
{
readfile("image1.jpg");
}
else
{
readfile("image2.jpg");
}
?>
Is there something I can put in the if-statement to make it work? Possibly that works in all browsers?
Is there a way to do this without php?
You could use the referrer URL in the request and check to see if it is your domain. This is done using $_SERVER['HTTP_REFERER'].
However, the HTTP_REFERER URL can be easily modified by clients and can even sometimes not be set, so you need to be careful when using it.
I don't know, how you're going to get request for image not in your domain, but you may look at $_SERVER['HTTP_HOST']. Maybe, HTTP_REFERER is what you need. Anyway look here.
I have a free PHP webserver and I would like to provide a redirect to external links page, just like deviantart.com does. Is there any way to do this with just PHP? I have no access to the server.
Edit: I meant a page asking "Are you sure you want to leave [MA WEBSITE]? NOPE ; DUH - GO TO http://outside-example.com"
Edit2: I actually meant a function to catch outside links and replace them with a /redirect/?url=PARSED_URL_ADDRESS
You need to detect if there is any link which redirects to outside website then you need a page to show something like "Now Leaving yourwebsite.com"
If that is the case then you need to analyze the content of your page before rendering and find out if there is any tags and replace ref of them with some gatway.php?url=outgoing-url
Where in gateway.php compare if the url belongs to your website or external website by using string comparison methods
Use this js code in footer (I am expecting there is some common footer page)
var urls = document.getElementsByTagName("a");
for (urlIndex in urls ) {
urls[urlIndex].href = "dummy.php?url="+urls[urlIndex].href; //replace dummy.php with urs
}
You mean like header('Location: http://www.example.com/');?
Provide, for example, a function that creates <a> tags. Or just one that converts URLs to your redirector: redirect.php?url=http://.... The redirector then issues a HTTP header called "refresh" set to the new address.. Beautify it so the user knows he is being redirected, voilá.
Find out yourself how :)
The best way to do it is using the location header, but you also need to set a 301 response code, this also tells the search engines crawling the link that the content at that url is at a different location, and it's a best practice to set the response code for redirects in general.
Header( "HTTP/1.1 301 Moved Permanently" );
Header( "Location: http://www.new-url.com" );
I am designing a site where external links form various are being shown on my page. I am using
$url=$_GET['url'];
$website_data = file_get_contents($url);
echo $website_data;
so essentially a user would click on a hyperlink which is something like www.test.com/display_page.php?url=http://www.xyz.com/article/2.jpg
My page, list_of_images.php, typically has a list of images with href for each image as above on the page and when any image is clicked it would go to display_page.php, which would show our banner on the top of this page, some text and then this image beneath that. This image could be from any website.
I am currently sending the url directly and grabbing it using GET. I understand that users/hackers can actually do some coding and send commands for the url variable and could break the server or do something harmful and so i would like to avoid this method or sending the url directly in the header. what is the alternate approach for this problem?
The safe approach is to use a fixed set of resources stored in either an array or a database, and the appropriate key as a parameter.
$ress = Array('1' => 'http://www.google.com/', ...);
$res = $ress[$_GET['res']];
I would make sure the url starts with http:// or https://:
if(preg_match("`^https?://`i", $_GET['url']))
// do stuff
You may also want to make sure it isn't pointing anywhere internal:
if(preg_match('`^https?://(?!localhost|127\.|192\.|10\.0\.)`i', $_GET['url']))
// do stuff
Rather than a big dirty regex, you could go for a more elegant host black-list approach, but you get my drift...
Try POST....
Try doing this using POST method
