I have a self-made math captcha and it should be output without anything before it's image header, so I can't make it a 'View'. I put this captcha.php in the web root dir, but it can't share session with scripts in Yii. How to solve this?
Is there any way to pass the session from Yii to the other scripts or clean anything before the header in view?
Though it is true that the default layout wraps the page's content with the typical html markup you'd expect, you have complete control over that by specifying the layout you'd like from the controller by using $this->layout = ... You can set it to null to use module layout or false to disable the layout completely. See more details in Yii API Docs.
Alternatively you can call $this->renderPartial('view name') if you'd like the output of your captcha script displayed without the surrounding page content.

Currently I have subdomain.mydomain.com, which redirects to mydomain.com/subdomain(I am using a PHP - codeigniter framework).
But all I want is after redirection url should remain subdomain.mydomain.com instead of mydomain.com/subdomain.
Is there any way to achieve this?
if you like to keep it pure html + php, i suggest you look into the iframe tag from html.
it is basically a browser window within your current browser window. Set the iframe to cover up 100% of your current browser window and set it's url to mydomain.com/subdomain.
what you'll see is that it's displaying content from mydomain.com/subdomain but your url field in your main browser is still saying subdomain.mydomain.com
Write this code in the routes.php file(present in config folder):
$route['mydomain.com/subdomain'] = "subdomain.mydomain.com";
Basically it's logic is
$route['route_you_want_to_show'] = "current_route";
But mind well in codeigniter routes are formed from the redirection of code to controller and its methods.

I have got the layout working properly. However, I want to ask a couple of questions in order to get my set up perfect for the way I want it.
Is application>styles a good place for the stylesheet to be? If not what's the recommended?
How do i add the stylesheet to the layout?
In my layout I have a title tag : <title>Text</title>. How do I pass values from my controllers to it?
Stylesheets need to be accessible from the browser, so typically you will put these somewhere in the public directory, such as public/css
There are several ways, including placing rel tags in your view/layout, but my preferred option is to use the viewHelper within your controller:
$this->view->headLink()->setStylesheet('/css/style.css');
Then your call to headLink() in the layout file will automatically include the stylesheet.
The way I have done this is to use the Zend_Registry in the past. There may be better ways.
I feel my problem is relatively simple. I'm new to the Zend framework and I'd like to be able to call a controller to do some work for a header or a footer. I've already created a HeaderController and a applications/views/scripts/headers/index.phtml - all I'm trying to do is get that data, and put it in my layout by default.
Everything works if I navigate to /header, by the by.
Edit:
Made some progress - if I add:
$this->render("header/index.phtml");
it renders all the static data, but doesn't seem to be running the HeaderController.
Try this bit of code out, be sure to disable the layout in your header controller, as the purpose is only to render a limited amount of content.
<?= $this->action('index', 'header', null, array('possible_args'=>'here')); ?>
The documentation can be seen here.

I'm creating a website/codeigniter-project that uses views which link to external CSS files.
Everywhere throughout my project/web-page's views I can control the URL paths of images, links, etc by constructing them from the 'base_url' setting variable. I don't have any control over static, linked external CSS files. This means that whenever my base URL path changes for my site I have to go through my CSS files and do global search/replaces to update all my paths.
To solve this I thought about creating a controller just to load CSS/JavaScript files and treating the actual files like views with hooks but I was talked out of this by #WesleyMurch in this question:
Using a controller to handle returning customized css & javascript files with codeigniter
How can I dynamically assign base-paths to my css assets so I don't have to do global search and replaces every time I update the base path of my site?
For this I use a view file containing css code with all the variables. The only change is that you should set appropriate headers for CSS
Create function style in your controller and set it to render appropriate view file (style.php). Code all your css with php code in style.php.
Set following headers at the start of the function:
header("ContentType: text/css");
header("Expires: <some far future expiration time or use mod_expires with apache>");
I have a navigation menu inside a CakePHP element file (views/elements/nav_default.ctp).
The file is included inside another element that is the header (views/elements/header_default.ctp) which is then included in the layout file (views/layouts/default.ctp).
I am trying to tell Cake to load a js file (webroot/js/mega_drop.js) from within the nav element like so:
<?php
$this->addScript('mega_drop');
?>
It does not get included. I looked at the documentation for addScript which just says:
Adds content to the internal scripts
buffer. This buffer is made available
in the layout as $scripts_for_layout.
This method is helpful when creating
helpers that need to add javascript or
css directly to the layout. Keep in
mind that scripts added from the
layout, or elements in the layout will
not be added to $scripts_for_layout.
This method is most often used from
inside helpers, like the Javascript
and Html Helpers.
The key part:
Keep in mind that scripts added from the layout, or elements in the layout will not be added to $scripts_for_layout.
So how do I do it then?
I guess I could add a <script src="/js/mega_drop.js"></script> to the default.ctp layout. That doesn't feel right though as it would tightly tie the layout and the element together.
Whats the CakePHP best practice way to do this?
addScript() does not load a file; it adds actual code to the $scripts_for_layout variable. The idea being that the layout is a good, common place to load your JavaScript files and code. That way you can output all the code in one location - in the head block or at the end - either way it's together. So if you are in a situation where you've got JavaScript code in the view, rather than output it inline, you can pass it up to the layout.
The best way to load a script file is with the HTML Helper- echo $this->Html->script("script or array('of', 'scripts')"); With that in mind, you could $this->set('scripts', 'mega_drop'); in the element and then call the Html Helper with that $scripts variable from the layout.
The problem with that: it won't work if your nav_default.ctp is called from the layout. $this->set() works inside of a view (or an element called from a view) because the View is rendered before the Layout. If you are calling your element from the layout, then it is too late to be setting viewVars for use in the layout. The best thing to do is set() the scripts variable from the Controller and use a if(isset($scripts)) { echo $this->Html->script($scripts); } in the layout.
Correct and valid 1.3.x CakePHP 2.0 Dev is from example.ctp file:
$this->addScript($this->Javascript->link('tab_enabler'));
$this->addScript($this->Html->css('jquery.tabs'));
This is an example of how to properly include CSS and JS files from the view and adding in the variable $scripts_for_layout to not generate validation error with the W3C as it is not correct to add the link to a css file in <BODY></BODY>
try
$this->Html->script('mega_drop', $inline=false);
in your element without the echo.
The Second parameter says to add it to the $scripts_for_layout variable.
You should be able to do this in your element, so that the javascript is only included when the element is.
