When the facebook.com/profile/{username} is requested how is server able to load page with data corresponding to that user, instead of navigating to a directory named in that {username}, and possibly showing a 404 error ?
It's achieved typically using a pattern called "front controller", where all requests are handled by the same file (let's say index.php, talking specifically about PHP now). So all URLs are like this:
facebook.com/index.php/profile/abc
facebook.com/index.php/account
That file serves as the bootstrap for the application, reading extra parameters (anything after index.php) and dispatching requests to the appropriate handlers/controllers.
Then there's multiple ways you can get rid of that ugly index.php, depending on how you configure your web server (loads of questions here about that subject: htaccess remove index.php from url as an example).

I am hosting and developer on my DNN portal. I need to redirect users using client IP. I think may be two ideas for this work.
1- DNN Setting
Maybe DNN has settings for it that I can set specific URL for client IP addresses and automatically DNN redirects to specific URL.
I read many topic but I could not find setting to do it.
Is there a way to do this?
2- New Module
I have a ascx that onload method has this code:
var IP = Server.HtmlEncode(Request.UserHostAddress).ToString();
using (Entities db = new Entities())
{
var retVal = db.URLAddresses.Where(u => u.IPAdress == IP).FirstOrDefault();
if (retVal != null)
Response.Redirect(retVal.URL);
}
But I should add this code to any ascx for redirect using client IP. This is impossible because maybe I haven't source code modules.
I think I should create new module. So I can add it to page. Module changes onload page and redirect to URL using client IP.
In this scenario, I try to create new module but I don't know how I can change onload method each page that is added module to it?
You can use IHttpModule and make a new Module for Including your class then you should add your IHttpModule to web.config .
For e.g
<add name="YourModule" type="YourAssembly, YourNameSpace" preCondition="managedHandler" />
See this Sites:
HTTP Handlers and HTTP Modules Overview
and How To Create an ASP.NET HTTP Module
DNN does have a Host setting that will allow or deny access to users logging in based on their IP address. It's in Host Settings > Advanced Settings > Login IP Filters. I don't think that will give you the desired result.
I would not suggest creating a module. It can be difficult copying it to all pages and ensuring one instance is added to every page.
Rather, I would create a skin (theme) token. To do this, create a simple class library project. Create an .ascx and ascx.cs file. You can leave the .ascx empty because you don't have any html to add to the pages. In the .cs, put something like this:
namespace MyCompany.DNN.Skin
{
public partial class IpRedirect : SkinObjectBase
{
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
// Put your redirect logic here
}
}
}
Then, in your theme/skin ascx pages, include the following:
<%# Register TagPrefix="myco" TagName="IPREDIRECT" Src="~/DesktopModules/MyCompany/IpRedirect/IpRedirect.ascx" %>
<myco:IPREDIRECT ID="pageRedirect" runat="server" />
This will ensure that this functionality will execute on all pages in the site that use the skin/theme.
I'm using ZF for my project and my server directory structure is:
/ROOT
__/APPLICATION
__/Zend library
__/public_html(I put all the contents of public folder created by ZF here)
__/docs
__library
I have a single .htaccess file which I put in public_html folder. There are two issues that I want help for.
First,
the url links I'm creating using $this->url(array('controller'=>'home', 'action'=>'index'),null,true), for example, are resulting into <a href='/~wethemen/home'>...</a>, where 'wethemen' is my username on the hosting server account. I checked that in page source. That's why it is not rendering the requested controller and actions as well, may be.
Second,
Only the layout is rendered and no action. My default controller is 'home' so I get this error when I try to access the site.
script:''home'/index.phtml' not found in path (/home1/wethemen/application/views/scripts/).
This is the first time I'm deploying a ZF project on server. Any help will be greatly appreciated. I'll pour the contents of index.php and bootstrap.php if needed.
Just put
$controller = Zend_Controller_Front::getInstance();
$controller->setBaseUrl('/your/base/url');
where you find the text "->setRouter" or anywhere in bootstrap, before dispatch() is called.
Edit: if this does not work and you think it is a HTTP server rewrite issue, adding
RewriteEngine on
RewriteBase /
if you application is accessed at http://yourdomain.com/
or
RewriteEngine on
RewriteBase /your/base/url/
if the application is accessed as http://yourdomain.com/your/base/url/
i am trying to develop website using zend framework so i had created one index.php file where all my requests goes and c.reated two controller one is IndexController and other is TestController
Class IndexController extends Zend_Controller_Action{
public function indexAction(){
echo "Index Index Jamla";
}
public function displayAction(){
echo "Index Display Jamla";
}
}
now when i access the url http://test/
it correctly calls IndexController and its IndexAction function
but when i access the url http://test/index/index
it displays the message url /index/index was not found on this server same it does when i access http://test/test/index
though http://test/ is equivalent to http://test/index/index
The rewrite rules for Zend Framework are not working.
http://test works because Apache is defaulting to run index.php which will run your application. The router will see no URL parameters so it routes to index controller index action. When you attempt to access anything else, Apache is handling the request and is not rewriting it to index.php so you are getting a 404 not found.
Make sure the .htaccess containing the rewrite rules is in your public folder. Also check that Apache allows processing of .htaccess files for your document root by setting AllowOverride All in httpd.conf and/or httpd-vhosts.conf.
Make sure that you have set AllowOverride to All in your Apache configuration and have enabled the mod_rewrite extension
Silly but can you recheck again either index.phtml file exists under views/scripts/index/
I have a project in which I want to be able to call wp_list_pages() on a page that also uses the Zend Framework to power some complex interfaces manages custom data outside of wordpress.
This page should also redirect the user to the wordpress login screen if they're not already logged in with the appropriate level of authorization.
How would this work at a high level, i.e. do I need to edit the wordpress bootstrap file to conditionally implement the custom interface based on a specific URL or something, but still include certain files to be able to call wp_list_pages() on that custom interface?
I've developed a couple of WordPress plugins, and I've found it's really easy to extend. Haven't worked with Zend though.
You should check the WordPress plugin api. Mostly the part about actions, filters and hooks: http://codex.wordpress.org/Plugin_API
You can even override some functions (not sure if wp_list_pages() is overridable).
It's pretty well documented, and there's a large developer community behind it on IRC, forums, etc.
Thanks Fernando.
I just read this thread which suggests that you can use Zend in any script by just including:
require_once('Zend/Loader.php');
Zend_Loader::registerAutoload();
So given that all I need to use Zend for is on one page, can I just include that code in a custom template file that I assign to the appropriate page in the navigation? If I used javascript to submit the form via XHR, the requested URL would take the form '/controller/action' - but Zend wouldn't know the controller directory.
Could I put Zend code into the wordpress bootstrap, i.e. the above code plus the frontController configuration, and then use Zend wherever however?
So I've created a page in Wordpress and a custom template for that page, in which I've placed the following Zend Framework code:
require_once('Zend/Loader.php');
Zend_Loader::registerAutoload();
$db = Zend_Db::factory('Pdo_Mysql', array(
'host' => 'localhost',
'username' => 'username',
'password' => 'password',
'dbname' => 'dbname'
));
Zend_Db_Table::setDefaultAdapter($db);
class Users extends Zend_Db_Table_Abstract {
protected $_name = 'wp_users';
}
$users = new Users();
$users = $users->fetchAll()->toArray();
print_r($users[0]['user_login']);
This all works fine, so it's clearly possible to use Zend in conjuction with Wordpress at least to some extent.
It's becoming apparant that the problem is about who controls the URL rewriting, or the routing, or the bootstrapping (not sure of the correct terminology). If I were to put the end of the above code, starting $users = new Users();, into a controller as follows:
class UsersController extends Zend_Controller_Action {
function getUserAction() {
$this->_helper->viewRenderer->setNoRender();
$users = new Users();
$users = $users->fetchAll()->toArray();
echo $users[0]['user_login'];
}
}
How would I then call that function? My intention would be to call it from javascript via an XHR request in response to an event on the page, but requesting the URL 'index.php/Users/getUser/' returns 'No input file selected'. Trying to access the URL http://www.domain.com/Users/getUser/ produces a Wordpress 404 page.
Is there a way around this? It doesn't just apply to wordpress, of course - I expect it applies to any existing application that rewrites/routes requests via a bootstrap.
I guess you could do that, just import the framework into the one page you need it for. I don't know how Zend works, but check the paths as to where to put your directories so that Zend finds them.As I said I guess you could do that, just experiment and tell us how it went!
Beware of name conflicts for functions and/or variables, this shouldn't be much of a problem coming from such popular products as WordPress and Zend though... (which should be theoretically well coded)

I've built a plugin for wordpress that has a similar goal to yours, more modeled on CodeIgniter though. Not knowing Zend terribly well, I think this should help:
Make a file named routes.php in your plugins directory with the following code:
add_action( 'init', 'add_custom_urls' );
function add_custom_urls(){
global $wp, $wp_rewrite;
$wp_rewrite->add_rule( '(.*)$', 'index.php?&cPath=$matches[1]', 'top' );
$wp->add_query_var( 'cPath' );
}
Be sure to activate both plugins in your admin. These two files will allow you to catch the url before Wordpress tries to figure out what to do with it. You can use regular expressions to have finer control over which pages to catch. You may have to delete the record in your _options db table where option_name = 'rewrite_rules' before this works.
Next, make another plugin with the following code:
add_action( 'template_redirect', 'bootstrap' );
function bootstrap(){
global $cPath;
echo( "cPath : $cPath" );
if( $cPath ){
dosomethingwith( $cPath );
}
}
Put all your code in the dosomethingwith() function. You'll need to figure out if the url requested can me mapped to a zend controller, etc. http://www.domain.com/Users/getUser/ would give you $cPath = Users/getUser/ If successful, you'll also probably want to die(), so once it is completed Wordpress won't try and take over again.
