I am trying to redirect to a new page using CakePHP redirect method but for some reason the redirect is not working. The code I am using to redirect is
public function update_sticky_postition_in_db()
{
$this->autoRender = false;
... // Save info to database
$this->redirect(array('action' => 'tool'));
}
Where tool is the name of the view I am tring to redirect to. To try and speed the process of finding the problem I have checked few things and think I have found the cause of the problem. Basically I am trying to redirect to the view that is currently active which I think is part of the reason why it is not redirecting. I have read that it might have something to do with caching of the page but I am not sure how to solve that issue.
Also when using firebug I can see the redirect is sending a GET request but after that nothing is happening. Do I have to do something with the GET request or should Cake handle that for me. Also I have checked the URL of the GET and it is correct.
It is located within the controller with the correct name as I can view the original tool page.
Also the update_sticky_postition_in_db() method does not have a view (hence why the auto render is set to false), its intended purpose is to update a row in the database from an ajax call.
From your post it seems you're firing the update_sticky_postition_in_db() using ajax call, so that the redirection will not work.
You can do redirection using JavaScript within ajax success method.
In order to do that, you may send some json_encode() message from you above method and checking that status within ajax success method you can do a redirect using window.location.

This question is for CakePHP 4.3:
In my action, I am accessing the session. For a normal GET request, everything works fine. If I call the same action through an AJAX request, I do not have access to the session. Why is that?
For example, even this does not work:
public function select3() {
debug($this->request->getSession()->read());
}
For a GET request, the session is printed. For an AJAX call, an empty array is printed.
Is the AppController NOT called for an AJAX request?
Any help is appreciated!
First, thanks to "ndm" for your offered help.
I solved it after seeing that something was mixed up with the URLS.
The URL has "server-4.2" in it, and "server" is a link to it.
Both "server-4.2" and "server" seemed to have confused the Authentication controller.
Glad it works now.
I am working on codeigniter and I am making a login page. When i validate the credentials I wan to move the user to next view if the credentials are correct.
I am using following command to redirect the user but it is merging the new view to the existing view and the url being shown in the browser is also getting appended.
$this->load->view('DataEntry');
URL before executing this command :http://127.0.0.1:8080/ci/
URL after executing this command : http://127.0.0.1:8080/ci/index.php/CI/DataEntry
how can i redirect the user from one view to another without appending the url and what is the right way to do it ?
I am an abolute beginner. so accept my apologies for dumb questions.
In general, it should be something like this:
//pseudo code
if ($validation_passed)
{
redirect('secret_page_controller/secretpage_method');
}
else
{
//if validation failed
$this->load->view('view_where_login_form_is');
}
Follow basic example from docs.
Please, format your code appropriate and add controller/method(s) code.
I was looking at the example http://ellislab.com/codeigniter%20/user-guide/libraries/form_validation.html#validationrules (trying to learn codeigniter) and saw this code
$this->load->view('myform');
My question is does this cause the server to send a redirect back to the user? or does this return the user html code?
ie. I am looking to be completely REST based where a post should always redirect and never should return html(plus returning html on post screws up browsers and we have noticed the playframework model of post -> redirect -> get to work 100% of the time with browser back buttons and behaving the way a user would expect and want to keep that in place)
If the above does not redirect, anyone know of an example with validation failing that does a redirect and then displays the errors.
thanks,
Dean
$this->load->view('myform'); is a function that parse the html resource and output to the browser.
there is a redirect function in url_helper can do that.
But i just imply my function.
redirect is showing a message then redirect.
jump is jumping without a message.
message is showing a note message.
public function redirect($url,$message,$time=3){
$this->template->display('common/redirect',array('url'=>$url,'message'=>$message,'time'=>$time),$this->theme,$this->thcolor,false,0);
}
public function jump($url){
$this->template->content_display("<html><head><meta http-equiv='refresh' content='0;url={$url}'></head><body></body></html>");
}
public function message($heading,$message){
$this->template->display('common/message',array('heading'=>$heading,'message'=>$message),$this->theme,$this->thcolor,false,0);
}
It loads HTML . As a general advice I would stay away from CI. It has tons of security bugs and it's not suited for your purpose. Try laravel or better rails
EDIT: Removed non-relevant code/desc, since the issue was not just to do with the initial code there.
I have an MVC3 based application that uses a lot of Ajax calls (such as with jqGrid) and Forms Authentication. I also use the [Authorize] attribute on certain controller/actions that I call with Ajax in most cases. Every so often my application falls over with a 'This page isn't redirecting properly' or a 'this page has a redirect loop'.
I checked this out with fiddler. After logging in as a user and trying to access pages that require authentication, sometimes I get redirected to Account/LogOn which then goes into an infinite loop. This usually happens when I'm calling any controller/action with an Authorize attribute with an Ajax call. The application seems to send out a 302 redirect to Account/Logon. The Account/Logon call then seems to redirect to itself. And the textView on Fiddler shows the following.
<html><head><title>Object moved</title></head><body>
<h2>Object moved to here.</h2>
</body></html>
I have the following in my Global.asax file
protected void Application_EndRequest()
{
var context = new HttpContextWrapper(this.Context);
//if we are an ajax request and forms authentication caused a 302, then we actually need to do a 401
if (System.Web.Security.FormsAuthentication.IsEnabled && context.Response.StatusCode == 302 && context.Request.IsAjaxRequest())
{
context.Response.Clear();
context.Response.StatusCode = 401;
}
}
And this in my main Layout page
<script type="text/javascript">
$(document).ajaxError(function (xhr, props) {
if (props.status == 401) {
location.reload();
}
});
</script>
My web.config setting for Forms authentication has this
<authentication mode="Forms">
<forms loginUrl="~/Account/LogOn" timeout="2880"/>
</authentication>
The redirect starts every so often and it is not with the same controller/action either. Just seems quite random. I am not sure if the cookie is expiry for the user and causing this issue for some reason or if it is an issue with the application pool recycling. Any suggestions on how to get around this would be most appreciated. Been struggling with this the last few days now, so any help from the experts will be great. Thank You
decorate your action method with Authorize attribute to make it available to authenticated/logged in users, after that check user role.
I don't see a loop in the above code. But maybe in one of controller1 or controller2 you have a redirect back to this home/index action.
I would suggest to run fiddler while testing the site, when a redirect loop happens you can easily detect it there, and then it is easier to find out what's wrong with the code.
Please see the answer in the linked question. This was the resolution to my redirect loop problem. Thank you for all your inputs.
IIS Session timeout and Forms Authentication loop
Is there a way to redirect a user to a page (login page in my case) when an AJAX query is made by the user to a server? The server is supposed to serve data only if the session is set or else the user should be redirected. I have tried sending a header("location:...") request but the browser handled it as a string (xmlhttp.response) rather than acting on it.
Not directly. Your callback function would have to handle it.
For example, if the server sends the text "LOGIN;/login.php;" then your onreadystatechange call back could have the snippet
if (xmlhttp.responseText.substring(0,6) == 'LOGIN;') {
window.location.href = xmlhttp.responseText.split(";")[1];
return;
}
If you're using a framework for the Ajax, this code could be in whichever callback gets the result of the Ajax call.
No. Not directly. You can return something special which should be handled as a redirect. But since the browser isn't looking to navigate and it won't.
In the callback function you can set the window.location to the new page if the session is not set.
