Is this the right way to create a form widget in FuelPHP?
class Controller_Widget extends Controller
{
public function action_show()
{
if (Request::is_hmvc())
{
// show form widget
}
else
{
// process form
}
}
}
The form action calls the same function to process, but where will it redirect to after? how will it show validation errors?
Note: The widget should not be accessible through the URL; the form should not display itself if accessed directly through the URL.
EDIT:
Found a similar problem in CodeIgniter HMVC and dynamic widgets but this is from 3 years ago. Maybe the FuelPHP guys have found a better way to do this.
This seems like a weird method, a method that is called show but handles both showing and manipulating data? A method called "show" (or get, fetch, read, etc) shouldn't do any editing, it's name expressly seems to imply that it's a read-only operation.
But also how it proceeds seems off. Its read-operation is HMVC only but its manipulation operation is non-HMVC only? That's really a wrong way to determine what the method should do, whether or not it is HMVC should have no baring on what it does.
In your case I'd split this up into 2 methods: one for retrieval (show()) and another for manipulation (edit() for example). Whether you want to make these HMVC only is up to you. There's more ways than one to solve that, I'd go with:
if ( ! Request::is_hmvc())
{
throw new Exception('Only HMVC access allowed.');
}
Or make it impossible to route to the method by rerouting it in your routes.php config file and then using the HMVC routing overwrite as discussed here: https://stackoverflow.com/a/9957367/727225

I'm attempting to create a custom display in yii2 framework using this code in my site controller:
/******/
public function actionChartDisplay()
{
return $this->render('chartDisplay');
}
for testing purposes I pasted the form name in my actionAbout function as a parameter to the render function in it. It worked with this:
public function actionAbout()
{
return $this->render('chartDisplay');
}
But I need to create many custom views in yii2 and this won't be a solution.
This is the error I get
I'm curious as to why it is. Since I was following this tutorial and came across this weird behaviour.
My 'chartDisplay.php' file is merely a "hello world" that does work with the action about function.
in yii2, the controllers and actions with multiple words, that are marked by capital letters are divided by - in your request, so in your case the route would be some/chart-display
Apparently as #SmartCoder pointed out it was an error on how Yii2 Handles the action functions in its controller however I didn't mark his answer as the solution right away because implementing it resulted in an error. So aside from that I'm posting the way I solved it.
So instead of using chart-display I simply changed it for "charts" like this:
public function actionCharts(){
return $this->render('charts');
}
Changed the name of my file so it fits to charts.php and it worked.
I'm writing a control panel for my image site. I have a controller called category which looks like this:
class category extends ci_controller
{
function index(){}// the default and when it called it returns all categories
function edit(){}
function delete(){}
function get_posts($id)//to get all the posts associated with submitted category name
{
}
}
What I need is when I call http://mysite/category/category_name I get all the posts without having to call the get_posts() method having to call it from the url.
I want to do it without using the .haccess file or route.
Is there a way to create a method on the fly in CodeIgniter?
function index(){
$category = $this->uri->segment(2);
if($category)
{
get_posts($category); // you need to get id in there or before.
}
// handle view stuff here
}
The way I read your request is that you want index to handle everything based on whether or not there is a category in a uri segment. You COULD do it that way but really, why would you?
It is illogical to insist on NOT using a normal feature of a framework without explaining exactly why you don't want to. If you have access to this controller, you have access to routes. So why don't you want to use them?
EDIT
$route['category/:any'] = "category/get_posts";
That WOULD send edit and delete to get_posts, but you could also just define those above the category route
$route['category/edit/:num'] = "category/edit";
$route['category/delete/:num'] = "category/delete";
$route['category/:any'] = "category/get_posts";
That would resolve for the edit and delete before the category fetch. Since you only have 2 methods that conflict then this shouldn't really be that much of a concern.
To create method on the fly yii is the best among PHP framework.Quite simple and powerful with Gii & CRUD
http://www.yiiframework.com/doc/guide/1.1/en/quickstart.first-app
But I am a big CI fan not Yii. yii is also cool though.
but Codeigniter has an alternative , web solution.
http://formigniter.org/ here.
Situation: only main page is accessible by default, all other pages needs a logged in user. When a module is loaded without user, a login template should be displayed, and no module. In other words, the $sf_content must be emptied in layout.php which is not 100% ok since there is logic in the layout. Is there elegant way for that? I dont think a helper is OK either....
Check out security filters, this is one standard way security is designed in symfony.
You even can implement your own SecurityFilter class with the functionality you want.
http://symfony.com/legacy/doc/reference/1_4/en/12-Filters#chapter_12_security
It is done by default for you by the sfBasicSecurityFilter filter. You just need a good configuration. Read this part of the Jobeet tutorial. You should use sfDoctrineGuardPlugin (or sfGuardPlugin if you using propell) for user authentication.
To complete my comments above: There are different ways to override the layout. You could use the methods:
setLayout($name)
//or using foward, which forwards current action to a new one (without browser redirection)
forward($module, $action);
inside your action class. In case you wand to modify the layout inside a filter, you can use something simular to this:
class yourFilter extends sfFilter {
public function execute($filterChain) {
if($yourConditionForOverrideTheDefaultLayout) {
//here the syntax to change the layout from the filer
$actionStack = $this->getContext()->getActionStack();
$actionStack->getFirstEntry()->getActionInstance()->setLayout('yourLayout');
}
$filterChain->execute();
}
}
To avoid unnecessary duplication in the layout file you can work with Fragments and Partials.
everyone. I've started using atk4 in a personal project a couple weeks ago and have been facing some difficulties since then. This specific question I want to ask is about how to make form validations when using the CRUD component shipped with the atk4 framework.
I have already tried several different solutions, none of them solving my problem.
I have a feeling that the problem here might be that the form validation happens within the call of the method $form->isSubmitted() (am I correct?). Since when using a CRUD component within a Page we don't use that way of processing the form submission, we'd have to find alternatives to it. For example, let's say I have a Page with the following init() function:
function init() {
parent::init();
// create a CRUD and set a model to it
$crud = $this->add('CRUD');
$m = $crud->setModel('Person');
if ($crud->form) {
$fn = $crud->form->getField('first_name');
$fn->validateNotNull('The first name must not be empty.');
}
}
Even though I've added the validation to the first name field, it won't be validated. I've tried several things, unsuccessfully. I tried to extend the CRUD class and reimplement the formSubmit($form) function, adding the validation there. Even if I do it, it doesn't work.
Originally (in the CRUD class), there is the function:
function formSubmit($form){
$form->update();
$this->api->addHook('pre-render',array($this,'formSubmitSuccess'));
}
I tried to iterate through the form's fields and call its validate() method, but it didn't work. Also, if I try to do alter the function (in a MyCRUD class, let's say) like below,
function formSubmit($form){
if ($form->isSubmitted()) {
$form->update();
$this->api->addHook('pre-render',array($this,'formSubmitSuccess'));
}
}
there happens an infinite loop... Could someone help me out?
[EDIT]
One last question intimately related to this one. I've just tried to do the exact same validation proposed by romanish below but, instead of adding a CRUD to a page, I was just adding a Form, and it doesn't work -- though the CRUD does work. Instead, there happens a "Error in AJAX response: SyntaxError: Unexpected token
CRUD component respects the validation you're doing inside the model. When data is entered into the form and button is clicked, $model->update() is called.
The execution continues into beforeUpdate() hook, which is the one you need to intercept.
http://agiletoolkit.org/learn/understand/model/actions
class Model_Book extends Model_Table {
function init(){
parent::init();
// .... more definitions ...
$this->addHook('beforeSave',$this);
}
function beforeSave(){
if(strlen($this['book_name']<10))
throw $this->exception('Name of the book is too short')
->setField('book_name');
}
If model is unable to save itself and will produce exception, Form automatically show it as a field error.
I've volunteered to create some db app, and I told those guys that it will be very easy, since I wanted to use CakePHP. Sadly after some time they told me they want it inside their already existing web, which is ancient highly customized PHPNuke.
So what I want is to generate just content of one <div> inside an already existing page with CakePHP. I looked up on the internet, but I didn't find what I was looking for. I'm rather a user of the framework, not developer, so I don't know much about the backend and how MVC frameworks are working inside (and this is my first try with CakePHP, since I'm Rails guy).
What I did so far is disabling mod_rewrite for Cake. Inside PHPNuke module I included Cake's index.php and rendering views with an empty layout. This somehow works, but the thing is how to form URLs. I got it working by now with
http://localhost/modules.php/posts?op=modload&name=xxxxx&file=index&do=xxxxx
but with this all links to CSS and images on PHPNuke site are broken.
Is there any way to use something like
http://localhost/modules.php?op=modload&name=xxxxx&file=index&do=xxxxx&CakePHP=/posts/bla/bla
or any other way that could do the job? I really don't want to change anything in existing PHPNuke app.
Thank you very much
Well, if you don't understand how CakePHP works you'll have trouble doing what you want, since it would mean putting hacks into the CakePHP core files to bypass the default routing. This basically means that you would be re-working the way CakePHP works, so you can forget about ever updating to a newer CakePHP version, and maintenance would be hell.
If you want to modify the system, but keep PHP-Nuke, I'd advise against jamming CakePHP in there, since that would open up too many problems to be able to predict beforehand.
I think your options are as follows:
Learn how PHP-Nuke works so you can modify it
Use regular php for the pages
Either of those are easier by orders of magnitude compared to what you wanted to do.
So to sum up solution I found, if someone will be looking for something similar. Problem solved by using two custom route classes ( http://manual.cakephp.neoboots.com/2.0/en/development/routing.html#custom-route-classes )
class CustomParserRoute extends CakeRoute {
function parse($url) {
if (parent::parse($url) != false) //if default parser has the match continue
{
// call to Router class to do the routing for new url string again,
// if &cakePHP= is in query string, use this, or use default
if ($_GET['cakePHP']) {
$params = Router::parse($_GET['cakePHP']);
} else {
$params = Router::parse("/my_controller");
}
return $params;
}
return false;
}
}
class CustomMatcherRoute extends CakeRoute {
// cusotm mathc function, that generates url string.
// If this route matches the url array, url string is generated
// with usual way and in the end added to url query used by PHPNuke
function match($url) {
$result_url = parent::match($url);
if($result_url!= false) {
$newurl = function_to_generate_custom_query()."&cakePHP=".$result_url;
return $newurl;
} else {
return $result_url;
}
}
}
And then simple configuration in routes php
App::import('Lib', 'CustomParserRoute');
App::import('Lib', 'CustomMatcherRoute');
// entry point to custom routing, if route starts with modules.php it matches
// the url and CustomParserRoute::parse class is called
// and route from query string is processed
Router::connect('/modules.php', array('controller' => 'my_controller'), array('routeClass' => 'CustomParserRoute'));
// actual routes used by cakephp app, usual routes that need to use
// CustomMatcherRoute classe, so when new url is generated, it is modified
// to be handled later by route defined above.
Router::connect('/my_controller/:action/*', array('controller' => 'my_controller'), array('routeClass' => 'CustomMatcherRoute'));
