How do I access GET/POST from a view helper? - typo3

I have a custom content element which uses a view-helper that inherits from link action. I want to use specific CSS when this link is "active". One way to do this would be to read _GET and check for link variables. Can I access _GET in a sane way from a view-helper? Or is there a better way?
Maybe this is impossible because the output of the view-helper will be cached...
I could of course access $_GET directly, but will this work with RealUrl?

Of course you can, the same way as you would do it within controller:
$fooInGet = \TYPO3\CMS\Core\Utility\GeneralUtility::_GET('foo');
$barInPost = \TYPO3\CMS\Core\Utility\GeneralUtility::_POST('bar');
$zeeAnywhere = \TYPO3\CMS\Core\Utility\GeneralUtility::_GP('zee');

silverstripe shortcode return dynamic template

I followed this instruction to be able to include a variable in the Content Field (HTMLEditor) of a Page - so that the variable can be replaced with other content:
http://www.balbuss.com/mini-introduction-to-shortcodes/
I want to display a list of dataobjects within the $Content.
Sadly the DummyHandler in the instruction is static. So I canĀ“t access the Controller in it, to let him do something (generate the list.)
Is there a solution to access the controller in a static function or maybe is there another better way to put a variable in the $Content.
Thx,
Florian
Controller::curr() is probably what you are after?
To use in conjunction with Controller::hasCurr(), as no controller would mean an error when using Controller::curr()

Zend creating forms based on requests within one controller/action

I don't really know how to word the title well, but here's my issue. I decided instead of having 25 controllers to handle pages, I have one PageController with a viewAction that takes in a :page parameter - for example, http://localhost/website/page/about-us would direct to PageController::viewAction() with a parameter of page = about-us. All of the pages are stored in a templates folder, so the viewrenderer is set to render application\templates\default\about-us.phtml.
I did this so I can consolidate and it seemed like a better approach. My question is the following: lets say when the page request is contact-us, I would need a Zend_Form to be used within the contact page. So, I would need a way within PageController::viewAction() to recognize that the page needs to have a form built, build the form, and also upon submission the need to process it (maybe this should be handled in an abstract process method - not sure).
I have no idea how to implement this. I thought maybe I can store a column with the name of a form and a connecting page identifier. Even better, create a one-to-many page to forms, and then in the submission loop through the forms and check if submitted and if so then process it (maybe there is a isSubmitted() method within zend_form. I really don't know how to handle this, and am looking for any help i can get.
Thanks!
Here is something that came to mind that may work or help point you in a direction that works for you.
This may only work well assuming you were to have no more than one form per page, if you need more than one form on a page, you would have to do something beyond this automatic form handling.
Create a standard location for forms that are attached to pages (e.g. application/forms/page). This is where the automatic forms associated with pages will be kept.
In your viewAction, you could take advantage of the autoloader to see if a form for that page exists. For example:
$page = $this->getParam('page');
$page = ucfirst(preg_replace('/-(\w)/ie', "strtoupper('$1')", $page)); // contact-us -> ContactUs
$class = 'Application_Form_Page_' . $page;
// class_exists will invoke the autoloader to map a class to a file
if (class_exists($class)) {
// a form is defined for this page
$form = new $class();
// check if form was posted
if ($this->getRequest()->isPost()) {
if ($form->isValid($this->getRequest()->getPost()) {
// form is valid - determine how to process it
}
}
// assign the form to the view
$this->view->pageForm = $form;
}
All this really leaves out is the action you take to process a specific form. Since the contact form will likely generate an email, and another form may insert data into a database, you will need some sort of callback system or perhaps another class that can be mapped automatically which contains the form processor code.
Anyway something along those lines is what came to mind first, I hope that helps give you some more ideas.

Drupal, overriding add/edit form forms for custom content type

I have created a new content type called protocol. The problem is that when you define a content type that means you also say how in the form the content is to be added and edited, like which form elements there will be.
A protocol is a content type that stores a title, an abstract and instructions. I want to add the title/instructions/abstract through one textarea where you tag the parts of the text like this:
[title]This is a title[/title] [abstract]This is an abstract. [/abstract][instructions]And these are my instructions.[/instructions]
That text is then processed and the content between each tag can be picked out and stored in a variable which should then be stored for the content type just like it had been added through a seperate field/textarea in a add/edit content form.
Is this possible to do? What kind of things should I read up on? Where in the drupal code are the function/functions that describes what happens when you push "Save" for a new content type for the standard add content form?(I just want to read it, not change anything)
Not sure this exactly matches what you're trying to do, but in a basic sense it should get you towards your goal. I wrote a module called endorse for Drupal 6 that provides a custom form feeding the submitted values into a new node:
http://drupal.org/project/endorse
Here's the form definition:
http://drupalcode.org/project/endorse.git/blob/refs/heads/master:/endorse.module#l136
Some basic validation follows and then the actual node save occurs at the top of the submit function, here up to line 231:
http://drupalcode.org/project/endorse.git/blob/refs/heads/master:/endorse.module#l206
The rest in that function is irrelevant except for the thank you and redirect at the very end of the submit function. If you're doing this in D7, it'll change a bit (see api.drupal.org for function definitions and whatnot), but it should look more or les the same.
Steps to solve your problem.
Create a module. Implement hook_menu with your custom add page.
Create a custom form using FORM API that it's gonna be displayed in your new page.
In your hook_form_submit get your values from the variable form state.
Parse the text and create and save a new node (snippet here).
$newNode = (object) NULL;
$newNode->type = 'protocol';
$newNode->title = $parsed_title;
$newNode->uid = 1;
$newNode->created = strtotime("now");
$newNode->changed = strtotime("now");
$newNode->status = 1;
$newNode->comment = 0;
$newNode->promote = 0;
$newNode->moderate = 0;
$newNode->sticky = 0;
// add CCK field data
$newNode->field_{YOUR_CUSTOM_FIELD_1}[0]['value'] = $parsed_data1;
$newNode->field_{YOUR_CUSTOM_FIELD_2}[0]['value'] = $parsed_data2;
// save node
node_save($newNode);
Those are the basic steps. If you have any more questions please ask.
TIP: Install the Devel module and use the function dpm() when you need to know the contents of some variable. You are probably gonna need it when you are implementing hook_form_validate or hook_form_submit for knowing the contents in the variable $form_state.
So just do:
dpm($form_state); //this will give you the variables inside the array with a krumo view.

Zend Form Element with Javascript - Decorator, View Helper or View Script?

I want to add some javacsript to a Zend_Form_Element_Text .
At first I thought a decorator would be the best way to do it, but since it is just a script (the markup doesn't change) then maybe a view helper is better? or a view script?
It seems like they are all for the same purpose (regarding a form element).
The javascript I want to add is not an event (e.g. change, click, etc.). I can add it easily with headScript() but I want to make it re-usable , that's why I thought about a decorator/view helper. I'm just not clear about the difference between them.
What is the best practice in this case? advantages?
UPDATE: Seems like the best practice is to use view helpers from view scripts , so decorators would be a better fit?
Thanks.
You could create your own decorator by extending Zend_From_Decorator_Abstract and generate your snippet in it's render() method :
class My_Decorator_FieldInitializer extends Zend_Form_Decorator_Abstract {
public function render($content){
$separator = $this->getSeparator();
$element = $this->getElement();
$output = '<script>'.
//you write your js snippet here, using
//the data you have in $element if you need
.'</script>';
return $content . $separator . $output;
}
}
If you need more details, ask for it in a comment, i'll edit this answer. And I didn't test this code.
Use setAttrib function.
eg:-
$element = new Zend_Form_Element_Text('test');
$element->setAttrib('onclick', 'alert("Test")');
I'm not actually seeing where this needs to be a decorator or a view-helper or a view-script.
If I wanted to attach some client-side behavior to a form element, I'd probably set an attribute with $elt->setAttrib('class', 'someClass') or $elt->setAttrib('id', 'someId'), some hook onto which my script can attach. Then I'd add listeners/handlers to those targeted elements.
For example, for a click handler using jQuery , it would be something like:
(function($){
$(document).ready(function(){
$('.someClass').click(function(e){
// handle the event here
});
});
})(jQuery);
The benefit is that it is unobtrusive, so the markup remains clean. Hopefully, the javascript is an enhancement- not a critical part of the functionality - so it degrades gracefully.
Perhaps you mean that this javascript segment itself needs to be reusable across different element identifiers - someClass, in this example. In this case, you could simply write a view-helper that accepts the CSS class name as the parameter.
"the markup doesn't change", Yap,
but I like to add some javascript function throw ZendForm Element:
$text_f = new Zend_Form_Element_Text("text_id");
$text_f->setAttrib('OnChange', 'someFunction($(this));');
The best way is if you are working with a team, where all of you should use same code standard. For me and my team this is the code above.

Line breaks in Zend Navigation Menu labels

I have a need to create a <br/> tag in the display label for a menu item generated using Zend_navigation, but don't seem to be able to find a way to do so.
My navigation item is defined in the XML config as:
<registermachine>
<label>Register your Slitter Rewinder</label>
<controller>service</controller>
<action>register</action>
<route>default</route>
</registermachine>
I want to force a tag in the output HTML between 'your' and 'slitter', such that it appears on two line as below:
Register your
Slitter Rewinder
However, I can't seem to do it. obviously using in the XML breaks parsing, and using html entities means that the lable is displayed as:
Register your <br/>Slitter Rewinder
Has anyone had experience of this that can offer advice?
Thanks in advance!
there is no such option built-in you have to use a partial
$partial = array('menu.phtml', 'default');
$this->navigation()->menu()->setPartial($partial);
echo $this->navigation()->menu()->render();
http://framework.zend.com/manual/en/zend.view.helpers.html#zend.view.helpers.initial.navigation.menu
you may also try a hack with <label><![CDATA[Menu label<br/>Second line]]></label>
I found a (hacky) solution:
I updated my navigation.xml to use {br} tokens wherever a <br/> tag is required, and then amended the base Zend/View/Helper/Navigation/Menu.php file as follows:
within htmlify function, changed
$this->view->escape($label)
to
str_replace("{br}", "<br/>", $label)
I could (and probably will) override the Zend Library Menu View Helper with my own at some point, but this at least cover it for now.
there is a escapeLabels boolean used to convert html tags and it's true by default.
You can set your navigation like this
$this->navigation()
->menu()
->escapeLabels(false)
->...
