I am trying to route an external webpage to a local file on my machine.
For example:
https://example.org/something/page.php
should redirect to:
c:\local.html
I don't want to redirect all traffic from that domain, only this particular page.
I do not have access to the website so I can't change it.
It's a PHP script. This means you can use PHP's header() function to do what you need.
You'd use it like this:
<?php
header('Location: file://path/to/file.html');
?>
If you want to redirect to a different page on the same server simply use
<?php
header('Location: /path/to/file.php');
?>
This would cause all traffic that lands on that page to be redirected to that local path.
For the best performance you'd want to put this at the top of your script so that the page does not execute more PHP code than needed.
Also do note that any local files will not be visible for other users visiting your page on the interweb.
This means that whenever someone lands on page.php he or she will be redirected to the same path on their local PC so if that is not there they will get a 404 of some kind.
If you want it to happen immediately as you visit the page, add this inside your <head>-tag.
<meta http-equiv="refresh" content="0; url=file:///c:/local.html" />
Same can be achieved with Javascript, if you add this to your <script>-tag inside your <head>-tag.
window.location = "file:///c:/local.html"
And since I see you're using PHP, this might be ideal to you as well:
header('Location: file:///c:/local.html');
Using either one works, but I would prefer the PHP option. Simply add it inside your <php>-tag (at the top would be prefered).

I have search on the web, yet I can't get the answer where a single PHP file could redirect to given url.
Like example I see on the website when I click the contact link on the menu I can see the url like below. And it redirect me to contact page. Even when I try placed other domain on the redirect 'to' location it can work as usual.
What is the best way to have a single file where could work like this
example.com/redir?s=icon_topost&url=http://www.example.com/contact (redir)
or
mydomain.com/redir.php?=http//www.mydomain.com/contact (redir.php)
I have try this code. I can't.
<?php header('Location: http://'); ?>
Thanks.
This code should work, but you must have not returned anything in the body to be able to change headers. What's the error PHP is displaying?
<?php header("Location: $_GET['url']"); ?>
I have the following code in my index.php page:
<?php include("/includes/widgets.php") ?>
And in my widgets.php page:
<?php
header("Location: /");
?>
What I want to achieve with this is to redirect it if the user visits it, but allow it for including.
But I get the following error:
The webpage has a redirect loop
How can I fix/prevent the redirect loop, but still redirect the user and not the server.
Place the widgets.php file in a folder not accessible to HTTP clients. I.e on apache webserver, either put it above your document root (into it's parent) or use .htaccess file to block users from it.
e.g.
deny from all
I think I know what you need :)
Change code index file to next
define("IS_INDEX", true);
include("/includes/widgets.php"
Change code for widgets.php to next
if (!defined("IS_INDEX")) {
header("Location: /");
exit();
}
The issue is you are redirecting back to the same page, which then redirect again, and again, and again.
An easy fix would be to wrap the redirect in an if, and only redirect if they aren't already on the index page; but this is just patching what looks like an architectural problem.
Something like:
if (ltrim($_SERVER['REQUEST_URI'], '/') != 'index.php')
header('Location: index.php');
One way is to check if __FILE__, which is the file loaded, regardless of included or not matches up with the file requested which is in $_SERVER['REQUEST_URI'] (or $_SERVER['PHP_SELF']).
I use this on our development site in a page that is usually included to get the output as debugging.
if(basename($_SERVER['PHP_SELF'])===basename(__FILE__)){
//do some debugging
}
Typically you wouldn't use basename, but this is on a non-public facing development site and the file has a pretty unique name so I'm not worried about the file being included with another file with the same name or anything.
One possible way is to add a parameter to the redirection, e.g.
if (!$_REQUEST['redirect'])
header("Location: /ìndex.php?redirect=1");
That way redirection can happen only once.
Another way is to stop redirection if the user already is on the /. I´d suggest to combine both.
Hey so I have create a login system to a website and I wish to have this login appear when I type in my address. When I have typed in details and logged in, I wish to be redirected to another PHP file, but with the same address.... this way, All I need to do is type in my address if I am allready logged in and I will go to the site which requires login.
I have made a transaction happen identifing if the session is created, if it is, it redirects me to another page, but also to another URL. I tried googleing it, but couldn't find anything exact and straight forward.
Currently:
Login page:
www.example.com
Member page:
www.example.com/members
What I wish for:
Login page:
www.example.com
Member page:
www.example.com
The program structure should look like this.
index.php
if (user is logged in)
display dashoard
else
display login page
Since you are using PHP, make use of session functions. Thus, URL rewriting is no longer necessary.
Update
Assuming if you have file structure in PHP like this:
- index.php
- login.php
+ template
- login.php
- dashboard.php
You can do the following structure in index.php file.
define('IN_FILE', true);
if (isset($_SESSION['user'])) {
require 'template/dashboard.php';
} else {
require 'template/login.php';
}
In template/dashboard.php
if (!defined('IN_FILE')) {
exit;
}
// Then your HTML, PHP and whatnot
And in login.php
if (!isset($_SESSION['user'])) {
require 'template/login.php';
} else {
header('Location: index.php');
}
Change the code according to your needs.
This can be achieved using several approaches.
a) Use session to determine the current page, so if a user click on a link, create a session store the value and on page load read the session data and include the file accordingly.
b) Use URL parameter to determine the page (this is the most common approach). for example in index.php you can add more parameters like index.php?page=somepage and by reading the value using $_GET and including the PHP file accordingly.
There are some more way to achieve what you want to, for instance using javascript/jQuery this is possible.
Supposed the page is example.com/blog/data.php. I am using file_get_contents to get the content in another script page. Now, i want to:
Forbid google search to crawl and index the data.php page.
Forbid the visitor to access it
Is there a way to achieve this?
You can redirect to another page if the request url is example.com/blog/data.php, but a far easier and more logical solution would be to move the file out of your web-root.
Edit: If you really want to keep the file inside the web-root, you can use something like this at the top of the script that you don't want to access directly:
if ($_SERVER['REQUEST_URI'] === $_SERVER['SCRIPT_NAME'])
{
header('Location: /'); // redirect to home page
}
However, this will probably not work in combination with file_get_contents (you need to remove these lines from the result), you could include the file instead.
Don't put data.php under the web root. Keep it in a parallel directory.
You can pass token via GET. Overall your way is slightly wrong. Why don't you incorporate the data.php logic in the script that is calling it.
Simply apply access restriction for authorized users only. You are able to do it in the most simple way by accessing your page using url parama as password:
example.com/blog/data.php?secret=someblah
and in the first of your file data.php do the following:
<?php
if (!isset($_GET['secret']) || $_GET['secret'] != 'someblah')) exit();
?>
However,It is recommended, don't use this from public computer becuase it is not secure but it is the primitive authentication principle.
How can I redirect a user to an external site while linking to an internal page ?
I have seen examples like:
example.com/go/ksdjfksjdhfls
example.com/?go=http://www.new-example.com
... And many more...
How this is achieved in php ?
Does this have any pros/cons with regards to SEO ?
I don't see any benefit in this approach, but there are a few ways to achieve it. To do it with the GET query, you would simply need the following code:
HTML:
Google!
PHP:
if (filter_var($_GET['site'], FILTER_VALIDATE_URL)) {
header('Location: ' . $_GET['site']);
}
With the above example, it will actually take the user to that location, not to:
http://example.com/link.php?site=http://www.google.com
To achieve the url being "local" while pulling up a remote site, you'd either have to:
Mess with URL rewriting, which can get messy and I'm not sure will let you do the above
Retrieve the remote page via curl and display it, which may screw up links on the "remote" page
Use iframes and set the iframe to be the size of the page. Note that this last method, while least offensive, is recognized as a potential security breach known as 'clickjacking' since it's used to trick users into clicking on a link for one page which his hiding a malicious link to another site. Many servers and browsers are taking steps to avoid this (for instance, google does not allow iframing of its home page), so this may also reach dead ends.
So of the three server-side methods I can think up, one may or may not be possible, and is a pain. One will be crippled and put a heavy load on the server. The last is a known bad guy and is likely not to work for many cases.
So I'd just go with a redirect, and really, if you don't need the address bar to show the local URL, then I'd just have a direct link.
All of the raises the question: What are you hoping to accomplish?
put this is beginning before any output to browser
<?
header('location:example.com\index.php');
?>
Set up an index php file which sets the header location to the url in the get parameter.
example.com/?go=http://www.new-example.com :
// example.com/index.php
<?php
if (isset($_GET['go'])) {
$go = $_GET['go'];
header('Location: $go');
} // else if other commands
// else (no command) load regular page
?>
example.com/go/ksdjfksjdhfls :
// example.com/go/ksdjfksjdhfls/index.php
<?php
header('Location: http://someurl.com');
?>
I use .htaccess rules for this. No PHP needed.
i.e.
Redirect 307 /go/somewhere-else http://www.my-affiliate-link.com/
So visiting http://www.mywebsite.com/go/somewhere-else will redirect to http://www.my-affiliate-link.com/.
On my site, I use "nofollow" to tell the search engines not to follow the link. The 307 status code means "temporary redirect".
Click here!
example.com/?go=http://www.new-example.com
you can use iframe and set the src attribute to http://www.new-example.com
<!DOCTYPE HTML>
<html>
<head>
</head>
<body>
<iframe src="http://www.new-example.com" width="100%" height="100%"></iframe>
