I would like to use the addCrumb method in my Layout to automatically add controller links. I tried this but the Html-Helper-Object in the Layout didn't contain the addCrumb Function. Then I tried to use the function in the beforeFilter in my AppController to set the Link but this wont work too (no error given). At last I tried to use an element to make this happen, but this didnt the job (error method not found).
I am using CakePHP 2.0 - has anybody an idea to solve my problem (without changing the *.ctp files by hand)?
PS: Using $this->html->addCrumb() in my specific .ctp-file works great.
To have access to HTML helper methods such as addCrumb, you must make sure the helper is loaded for whatever action you want to use it in. Simply do $this->helpers[] = 'Html'; in your controller (in an action or in your AppController to add it universally).

I have a project having lots of controller class files which do not contains index(). But If anyone type in address bar .../index then Zend show an error:
I don't need to create index() again an again in controller files. Can anyone suggest me here. What is the shortest way to fix this problem.
Any help would be appriciable.
In completion of Marcel's comments You have either in a controller (maybe UserManagementController) :
an indexAction.
Or an Action wich define this index template.
You have more solution that can fix this issue.
Using may terminate in route config to false, if it's what you want.
No controller nor action will be call.
Identify wich Action calls this template and fix it by returning the correct template or redirect to other action or return a notFoundAction.
I wanted the functionalities of view files to run in controller file also.
For example, I wanted $this->escapeHtml() which runs in view file alone to run in controller through some means like $this->...->escapeHtml()
Is this possible? Kindly help.
You need to get the ViewHelperManager and extract the EscapeHtml helper. This is a one example how to do it from the controller:
$viewHelperManager = $this->getServiceLocator()->get('ViewHelperManager');
$escapeHtml = $viewHelperManager->get('escapeHtml'); // $escapeHtml can be called as function because of its __invoke method
$escapedVal = $escapeHtml('string');
Note that it is recommended to escape and display the output in the view scripts and not in the controller.
I think this is a route issue but I'm not sure. I have a page with this URL:
siteurl.com/kowmanger/titles/titles/edit/$id
I'm trying to find out that when I'm on this page I load the titles page it says page not found so I need to tell it that the $id is just a paramter so I can use it to get the data of the title.
UPDATE :
So I decided to change my titles controller so that there's a edit and add function inside of the titles controller that way they dont' have separate controllers when they are in fact methods.
So now I have:
kansasoutalwwrestling.com/kowmanager/titles/titles - list of titles
kansasoutalwwrestling.com/kowmanager/titles/titles/add - addnew form
kansasoutalwwrestling.com/kowmanager/titles/titles/edit/$id - edit form
I don't have any routes set up so far for this. For some reason though I"m getting the same page for both of these page.
kansasoutalwwrestling.com/kowmanager/titles/titles/add - addnew form
(right link url) kansasoutalwwrestling.com/kowmanager/titles/add -
addnew form
I need a route so that it'll show the correct url if the add method is accessed.
Also I need to set up a route so that if the correct edit link is accessed it sees the id attached to the end of the url and it'll accept it so that I can do a my database query to get the title data.
UPDATE: So to reiterate I have a module(subfolder) called titles. Inside of the module I have a controller called titles and inside of that controller I have 3 functions called index(), add(), edit().
I tried using Chris's suggestion on the routes but its not routing correctly. Also wanted to mention I'm using wiredesignz modular separation framework if that matters.
Any additional ideas?
Possible answer based on your post, not one hundred percent your entire structure but if i had to guess based off the post I would try this as my routes first..
$route['titles/titles/edit/(:any)'] = 'titles/titles/edit/$1';
$route['titles/titles/add'] = 'titles/titles/add';
$route['titles/titles'] = 'titles/titles';
$route['titles'] = 'titles/index';
Are you using custom routing in your configuration files ?
The general routing protocol used by codeigniter is like this:
domain.com/controller/methode/param1/param2/param3
This being said, your url
siteurl.com/kowmanger/titles/titles/edit/$id
corresponds to something like this :
class Kownmanger extends CI_Controller
{
public function titles($titles, $action, $id)
{
}
}
In case you are using sub-folders in your controllers folder, what I have just said will change, Could you please tell us what's your directory structure ?
I have a controller that is called with AJAX (sends JSON data), so I don't use a view.
I need to use a personnal view helper to format my data, but in my controller.
Is that possible ?
Or maybe I am doing it wrong (maybe I should have a view, but how with JSON) ?
You can access any ViewHelper from the Controller by
$this->view->helpername(/*params*/);
// or
$helper = $this->view->getHelper('helpername');
// or
$broker = Zend_Controller_Action_HelperBroker::getStaticHelper('ViewRenderer');
$broker->getView()->helpername(/*params*/);
See Zend: How to use a custom function from a view helper in the controller?
However, you might be right that you are doing it wrong (funny pic btw), but I cannot really tell from your question. Please refine it as to why you need to call the view helper and what it is supposed to format.
Zend_Controller_Front::getInstance()->getParam('bootstrap')->getResource('view');
Just be sure that the returned view is the view you want. Because down the line, the view may get overwritten and on the controller you have a spank new view.
And all those values you setup on the view on the action helper and the like... before the controller is kicked in? All gone with the wind!
So test before assuming that if you get a view resource. it is really the same view resource you expect, and that all your vars are still there.
You may be surprised as i was!
You can create an instance of a Helper .. this will work in Controllers, Models and everywhere you need the Helper.
eg.
// create Instance
$serverUrl_helper = new Zend_View_Helper_ServerUrl();
// get the ServerUrl
$serverUrl = $serverUrl_helper->serverUrl();
Another approach is to use the ContextSwitch or AjaxContext action-helpers. This allows you to use a view-script from which you can then call your view-helper in the standard manner.
Just use action helpers, many of view helpers are available as action helpers too.
Or directly by using Zend_Date or sprintf.
I call an action helper in one of my views using the following code
echo $this->action('foo', 'bar');
The fooAction in the barController does its thing and outputs a list of pages. However, the list has the layout in the output again, which is mightily irritating. If I disable the layout in the fooAction, this causes layout to be completely disabled on the live side, as well.
I'm vexed. I could just create a view helper, and there are many ways around this, but out of curiousity I was wondering if anyone had a solution to this.
From the ZF Reference Guide on Action ViewHelper
The API for the Action view helper follows that of most MVC components that invoke controller actions: action($action, $controller, $module = null, array $params = array()). $action and $controller are required; if no module is specified, the default module is assumed.
Modify your controller to accept a param that controls whether the action should disable the layout. When using the action helper, pass this control flag.
On a sidenote: using the Action ViewHelper is considered bad practise as it will go through the entire dispatch process again and this will slow down your app. If possible, try to access the model directly.
