Here i use a href to show facebook login.after te click of href it will redirecting to facebook login instead automatically want to click and it will redirect the page.Is there any possible way to do that.If anyone know the solution for the problem please help me!!
Why not do this with header location? Here´s how that works: PHP header(Location: ...): Force URL change in address bar
For example:
$loginUrl = $facebook->getLoginUrl(array('redirect_uri' => $homeurl, 'scope' => $fbPermissions));
header("Location: " . $loginUrl);
Official docs: http://php.net/manual/function.header.php
No need for using an $output variable, or for creating a login page (if you want to auto-redirect anyway). Just redirect the user if he is not logged in yet. No need to do something shady like "auto-clicking the login button". It´s not a solution, it´s a bad workaround. Although, it would be a lot better if you would let the user click it. Redirecting to the login page without a proper intro page, where he can see what the App is about, is not a good idea.
Even better: Use the JavaScript SDK for login: http://www.devils-heaven.com/facebook-javascript-sdk-login/
If you want to change the webpage's URL, you do not need to use jQuery to click the link. Instead, there is a simpler way.
JS:
window.location = "http://www.example.com/";
By changing the window.location, you can "redirect" to a new URL.
If you want to redirect only after an event, you can put that in a function of yours.
Example:
window.location = "http://www.example.com"

When I go to the home page of my website, it does not have a default id in url.
How can I set a default id to my home page's url.
I want this : www.afgclick.com&id = 2
Just add a check to see if and id is set, and if not, redirect to the same url WITH that id.
In PHP: (thanks #Albzi)
if (!$_GET['id']) $_GET['id'] = 1;
If you need that parameter in the URL but you dont own the link that gets you to that page then try using something like:
HTML version
Create an index.html file containing the following code in the head section:
<meta http-equiv="refresh" content="0; url=www.afgclick.com&id=2" />
Javascript version
<script>
setTimeout(function(){location.href="http://www.afgclick.com&id=2"} , 3000);
PHP version
function redirect($url, $statusCode = 303){
header('Location: ' . $url, true, $statusCode);
die();
}
Good luck!
I am using the Google login client API for JavaScript. The site I am working on has two relevant pages. It has a login page, and it has a user profile page. The login page obviously has a Google login button on it. You should only be able to view your profile page when you are logged in. When a user goes to their profile page without being logged in, it should redirect them to the login page.
Here is an approach I have tried that did not work:
// This does not work because this event is only fired when the user logs in or logs out, but not when the user is already logged out.
gapi.auth2.init().isSignedIn.listen(function(state) {
if(!state) location.href = "/login/";
});
I have also tried detecting the login status of the user when the script loads, but that did not work either. It always redirected to the login page because the Google API can never log the user in by the time the script is done loading.
Additionally, I am trying not to use setInterval or setTimeout in my code, though, if that is my only valid option, please inform me.
By the way, I have heard multiple times that I can just set a variable when the user logs in, and then simply redirect to the login page if the variable is false. When would I check for the value of said variable? This will not work because it requires me to set a specific delay with setTimeout. Google's loading time can vary greatly, so I am not going to use that.
I figured out that you can use this simple expression that returns either true or false depending on whether the user is logged into Google on your website.
gapi.auth2.init().isSignedIn.get()
I'm no expert in the Google login API, however from the what I do know the API is purely for verification purposes, and (as far as I'm aware, I could be wrong) not actual user sessions. Everything else relating to the user account (IE, storing and persisting the login session in your case) are handled by you, the developer. The basic auth supports calling a callback function on a successful login, via data-onsuccess, which calls a JavaScript function on the login with the relevant login information. When a user logins the standard practice is to verify the validity of the user token returned, then you can do what you need with the data. In this case, you'd start some kind of session for the user.
A very basic example is as follows:
home page
<!DOCTYPE html>
<html>
<head>
<title>Test Home</title>
</head>
<body>
Login<br>
Profile
</body>
</html>
This has 2 links, one for the profile and one for the login page.
login/index.php
<!DOCTYPE html>
<html>
<head>
<title>Test Login</title>
<meta name="google-signin-client_id" content="YOUR-CLIENT-ID.apps.googleusercontent.com">
</head>
<body>
<div class="g-signin2" data-onsuccess="onLoginSuccess"></div>
<script type="text/javascript">
function onLoginSuccess(user) {
var user_id_token = user.getAuthResponse().id_token,
request = new XMLHttpRequest();
request.open('POST', 'https://www.googleapis.com/oauth2/v3/tokeninfo');
request.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
request.onload = function() {
authUser(request.responseText);
};
request.send('id_token=' + user_id_token);
}
function authUser(userData) {
var request = new XMLHttpRequest();
request.open('POST', '/login/login.php');
request.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
request.onload = function() {
if (request.responseText == 'true') {
location.href = "/";
}
};
request.send('user_data=' + userData);
}
</script>
<script src="https://apis.google.com/js/platform.js" async defer></script>
</body>
</html>
What this is doing is creating a very basic login button. The button has a callback of onLoginSuccess which is called when the user logs in with Google. It then grabs the users token, via user.getAuthResponse().id_token and makes a post request to https://www.googleapis.com/oauth2/v3/tokeninfo to verify the token (this can be done locally on your backend, Google provides libraries for it. However it's much easier to use the API endpoint). Once it is verified, it sends the response data to authUser, another function, which then passes it to the backend (/login/login.php) to actually start the user session.
login/login.php
<?php
session_start();
$user_data = json_decode($_POST['user_data']);
$_SESSION['user_data'] = $user_data;
echo 'true';
login.php simply starts a session, grabs the posted data, and sets the user session to the data posted. It then echos true so that the JavaScript knows it is done. The JavaScript then sends the user back the home page.
profile/index.php
<?php
session_start();
if (!isset($_SESSION['user_data'])) {
header('Location: /login');
}
?>
<!DOCTYPE html>
<html>
<head>
<title>Test Profile</title>
</head>
<body>
<img src=<?php echo $_SESSION['user_data']->picture; ?>><br>
<b>Welcome! <?php echo $_SESSION['user_data']->name; ?></b><br>
Sign out
</body>
</html>
What this page does is first check if the user_data session is set. IF it is not set (meaning the user has not logged in), it redirects them back to the home page. If it is set (meaning they are logged in) then it displays a picture and the users name, and has a logout button. When this is clicked it simply brings the user to /login/logout.php.
login/logout.php
<?php
session_start();
if (isset($_COOKIE[session_name()])) {
setcookie(session_name(), '', time()-3600, '/');
}
session_destroy();
header('Location: /');
All it does is remove all session data for the user, first getting rid of the session cookie and then destroying the actual session. It then leads them back to the home page. Clicking profile will now not allow them to view anything, because they are logged out, and will only display data when they log back in.
That is just a VERY basic and rough way of handling user sessions with the Google API. There are by far better ways (as this example has no real verification on the backend, and sessions are killed when the browser closes, so cookies may be better for you), however this is a general basis for handling user sessions.
I am trying to send data to php with ajax and at the same time redirect to that php file but when I redirected to the php file, the ajax didn't seem to send the data. I wanted to achieve something wherein a button is clicked and a data is sent to php using ajax and at the same time redirect to that php file to see the data sent by displaying it. The reason I didn't use something like window.location="ajaxtest.php?data=data" is because I'm gonna be using it in a google map api wherein if I click a button of a place, then I will redirect to the maps page and display the marker of the specific place depending on the id the ajax sent to the php file and the coordinates generated based on that id.
ajaxtest.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3
/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("#button").click(function(){
var data = "test";
$.post("ajaxtest.php",{
data: data
},function(data, status){
window.location="ajaxtest.php";
});
});
});
</script>
<button id="button">test</button>
</body>
</html>
ajaxtest.php
<?php
if(isset($_POST['data'])){
echo $_POST['data'];
}
?>
So, that's not how HTTP, AJAX, or PHP work. There isn't any POST data when you do your redirect, because the redirect is a separate request from the AJAX post. What you want is to do an AJAX post and somehow consume the response on your page, without doing a redirect at all.
It doesn't seem like ajax is the way to go here. If you want to redirect to a different page just do window.location.href = 'ajaxtest.php?id='+locationId; and in your ajaxtest.php:
<?php
$id = isset($_GET['id']) ? (int) $_GET['id'] : null;
if ( ! $id) {
die('ID missing');
}
// Show marker
?>
I have a simple form which is inside IFRAME. When user click on SUBMIT, it redirects to a specific page on my server. The function I use for the redirect is
header ('Location: mypage2.html');
exit ();
But I want the new page to open in _top location, not inside the same IFRAME that I use. How can I tell the browser to open the new page in _top not inside the IFRAME?
Thanks in advance.
You are not able to achieve the desired effect in PHP. This is something you'd have to do from JavaScript or add target attribute to <form>:
<form ... target="_top">
You can use javascript to access the parent. You could echo out javascript in your PHP.. so your parent page has this:
function changeURL( url ) {
document.location = url;
}
and in your php script, you echo
<script>
parent.changeURL('mypage2.html' );
</script>
The reason you can't call parent.document.location is because it's read only - you have to have a function available on the parent to do it.
A simple way directly in PHP to redirect the parent page rather than the iframe:
echo "<script>top.window.location = '/mynewpage.php'</script>";
die;
The die; isn't necessarily necessary, but it is good "just in case" to prevent the script from continuing any further, for example, if javascript is disabled in the user's browser.
we can use javascript like this :
target.window.location='locationpage.html';
top.window.location='mypage2.html';
The best and simplest thing to do is to use the form target element
<form action="..." target="_top">
<form action="..." target="_parent">
either of the target parameters works fine
You can either link to the page using Break Out or use code
<?php header("Location: pagename.php?Break=Y"); ?>
You then use the following code in the header of the page with
if(isset($_GET['Break'])) //
{
$BreakFrame = true;
$BreakToPage = "pagename.php";
}
<script language="JavaScript" type="text/javascript">
function changeURL( url ) {
document.location = url;
}
</script>
<?php if($BreakFrame) { ?>
<script language="JavaScript" type="text/javascript">
parent.changeURL('<?=$BreakToPage?>' );
</script>
<? }?>
In the page that you want to load in _top, add the follow code in the header
<script type="text/javascript">
if (top != self) top.location.href = location.href;
</script>
For CakePHP 4, to redirect your parent page just add option 'target'=>'_top' in your iframe's link:
Example:
<?= $this->Html->link(__('Redirect Parent'), ['controller' => 'Users', 'action' => 'view'], ['target'=>'_top']) ?>
All the best!
You can add multiple headers to your redirect.
I use a little function that I created with this in mind.
public function redirect($url){
header('Window-target: _top');
header('Location:' . $url, true, 303);
exit();
}
a page directs users back to a page automatically
<meta http-equiv="refresh" content="1; URL=http://localhost/mywebsite/Untitled9.php">
when it reaches 'Untitled9.php' i want it to display an alert box saying 'Message sucessfully posted'
I only want it to display when it id directed back to the page and not when first load
e.g Home - Message page = No alert
Home - message page - submit - redirect to message page = alert 'post sucessfully posted'
Can't control the DOM of a page externally.
What you could do however is pass a variable in the query string to the page you're redirecting to like this
Untitled9.php?message=success
Then on your new page have
<?php
session_start();
if ($_GET['message'] == "success" && $_SESSION['revisit'] == "0")
{
$_SESSION['revisit'] = "1";
?>
<script type="text/javascript">window.alert('Message successfully posted.');</script>
<?php
}
?>
In your first page change your code to look like this
<?php
session_start();
$_SESSION['revisit'] = "0";
?>
<meta http-equiv="refresh" content="1; URL=http://localhost/mywebsite/Untitled9.php">
If I understand your question correctly, this should work for you (assuming you alter the keys for the $_POST variables accordingly, of course):
<?php (isset($_POST['my_sub_btn'])): ?>
<script type="text/javascript">window.alert('Message successfully posted.');</script>
<?php endif ?>
Assuming you're submitting the message from a form, there should be no reason to redirect using a HTML redirect. Set the action attribute of your form to Untitled9.php and it will handle the rest...
Given your requirements, why not set a parameter on succes? Such as:
<meta http-equiv="refresh" content="1; URL=http://localhost/mywebsite/Untitled9.php?success=1">
