please tell me where the actions in a joomla 2.5 controller written. in joomla 1.5 i remember we use to write the actions like add, edit, remove, cancel etc in the only controller. but i am puzzled in joomla 2.5 because i find three controller even for helloworld component. and i also don't find the functions for actions defined in the controller. i saw only display function in the main controller.
then i also wanna know how each JToolbar button is mapped to an action in the controller.
First of all those methods are not shows in the controller that means its in library section.
For your requirement you can create new or same methods in any of the controller If you use same methods like save(), delete() cancel() etc its will override the Joomla's default functions.
In your toolbar section you can have mention the function name as well.
JToolBarHelper::title('Yor custom component', 'head vmicon48'); //set title
JToolBarHelper::apply('saveConfig'); //when the apply button click its will call the saveConfig function the controller.
JToolBarHelper::cancel();
For some toolbar button argument order may different you can find here.
Also if you have more than one controller from your form you can mention the controller like as follows.
<input type="hidden" name="option" value="com_helloworld" />
<input type="hidden" name="view" value="yourview" />
<input type="hidden" name="task" value="my_controller_fun" />
<input type="hidden" value="your_controller_file_name" name="controller">
Hope you will get some idea !

I need to create a form that by clicking on it will redirect to another website with special 'inputs' tags values.
something like:
<form action="http://example.com" method="post">
<input type="hidden" name="val1" value="something">
<input type="hidden" name="val2" value="else">
<input type="submit" name="submit" value="Go">
</form>
The custom HTML feature that I find will put it inside an iframe, and it looks bad. Is there a way to do it that will look 'normal'?
If you utilize Wix Code you can develop that inside your Wix page without the need of any html forms.
Simple solution:
- Add the form input elements you need on your page
- Add a button to click on
- Add av event handler to the button and grab the values from the input fields
- Send that data to any site or redirect the user to the site you want using wixLocation.to("url") with the query parameters you might need from the form.
I'm trying to cover my project with test and faced with problem.
The "press" method of TestCase fails with 'InvalidArgumentException: Unreachable field ""'
However the "see" method sees the needed button
Besides another form on another page tests fine
Hours of debug show me that the issue might be in the fact that the problem form has multiple (with this brackets []) inputs
Test code that fails
$this->type($params['from'], 'from[]');
$this->type($params['event'], 'event[]');
$this->type($params['class'], 'class[]');
$this->type($params['method'], 'method[]');
$this->press('save_handlers');
With form and button everythings is okey
Button:
<button type="submit" class="btn btn-primary btn-block" name="save_handlers">Save</button>
And of course button is in the form tag
Indeed, the problem is linked with the fact that there are attributes with brackets[].
I just had the same problem. I'm using a form with multiple checkboxes, and all of them have the same name (but different id) : codes[]. I'm doing this in order to retrieve them later (in a controller) simply as an array of values.
<input id="perm-0" type="checkbox" name="codes[]" value="perm-0" />
<input id="perm-1" type="checkbox" name="codes[]" value="perm-1" />
<input id="perm-2" type="checkbox" name="codes[]" value="perm-2" />
My friend var_dump() told me that the Symfony component which parses the form inputs doesn't like it when I'm using codes[] with nothing inside the brackets. It is seen as two fields : "codes" and "" instead of codes[]. That's causing the Unreachable field "" error.
A simple solution I found is to simply add an explicit index for the codes[] array :
<input id="perm-0" type="checkbox" name="codes[0]" value="perm-0" />
<input id="perm-1" type="checkbox" name="codes[1]" value="perm-1" />
<input id="perm-2" type="checkbox" name="codes[2]" value="perm-2" />
This way each checkbox is distinct from others, and the method press() does not cause the error any more.
It seems that this doesn't affect the processing of the resulting array in my controller.
This seems rather confusing seeing as the docs state this:
"Press" a button with the given text or name.
While the docblock above the actual press method states the following:
Submit a form using the button with the given text value.
So instead of using the value of the name attribute (save_handler) use the actual text (Save).
$this->press('Save');
I am very new to cs cart. I have read their documentation about calling Ajax with form micrformats. I am able to create a Ajax request. But I would like to call a controller inside my add-on controllers/frondend/ directory names as mycheckout.php. I am using the a hidden file dispatch with the valu mycheckout.mymode. Can any one help me. I actually want to perform some action in my controller. But their documentation did not help me. Thanks in advance.
You can do something like this (use extra "cm-ajax-force" or "cm-ajax-full-render" classes if needed):
<form class="cm-ajax" name="your_name" action="{""|fn_url}" method="post">
<input type="hidden" name="result_ids" value="div_id_to_be_updated" />
{include file="buttons/go.tpl" but_name="mycheckout.mymode" alt=__("Ajax button")}
</form>
Or you can use any button you want (even <input type="submit" name="mychechkout.mymode" value="Ajax!">)
Note that the Ajax request can be also done via simple link:
<a class="cm-ajax cm-post" href="{"mycheckout.mymode?param1=value1¶m2=value2"|fn_url}" data-ca-target-id="div_id_to_be_updated">Ajax!</a>
I have an issue with my portlet and I don't know exactly how to solve it.
My portlet adds or retrieves info from liferay's DB by inserting a name in 2 text fields.
After pressing the submit button, I see the response from the server, a JSON response like this:
{"id":301,"name":"Pepo"}
If a user correctly inserted or if the search throws a good result. I have to go back in the browser to see the portal again.
How can I use AJAX to pass the following URL dynamically from the portlet to the server without refreshing the page afterwards?
http://localhost:8080/c/portal/json_service?serviceClassName=com.liferay.test.service.TrabajadorServiceUtil&serviceMethodName=findByName&servletContextName=TrabajadorPlugin-portlet&serviceParameters=[param1]¶m1=NameInsertedByUser
Now I'm using the <form> tag like this:
<%
//Shows "New Employee" in the text field when portlet is rendered, or gets the user input and pass it as a param to the URL
PortletPreferences prefs = renderRequest.getPreferences();
String employee = (String)prefs.getValue("name", "New Employee");
%>
<form id="postForm" method="post" action="http://localhost:8080/c/portal/json_service">
<input name="serviceClassName" type="hidden" value="com.liferay.test.service.TrabajadorServiceUtil" />
<input name="serviceMethodName" type="hidden" value="create" />
<input name="servletContextName" type="hidden" value="TrabajadorPlugin-portlet" />
<input name="serviceParameters" type="hidden" value="[param]" />
<input name="param" type="text" value="<%=employee%>" />
<input type="submit" value="Submit"/>
</form>
I understand how AJAX works, but I need some help to create my function in order to achieve the URL to be correctly sent to the server for both GET and POST requests. This is my first try with AJAX.
Thank you very much, hope somebody understands my problem and could help me.
First of all, I see no point at all to use JSON services here. Just write ordinary portlet with MVC Controller, and in controller write action handling for corresponding actions (storing data, searching etc).
In controller you can directly call static methods like create or findByName from java class com.liferay.test.service.TrabajadorServiceUtil (or TrabajadorLocalServiceUtil) - that's how people usually do it.
If for some reason you really must use JSON, you should of course do these actions with AJAX calls - and render results using JavaScript.
Updating after question update:
The easiest and most correct way to send AJAX requests in Liferay would be to use AlloyUI JS framework that's a part of Liferay. You can read more on how to send AJAX requests with it here: http://www.liferay.com/web/nathan.cavanaugh/blog/-/blogs/4733559
In order to accomplish your goal I'd suggest implementing processAction(ActionRequest actRequest, ActionResponse actResponse) method in your controller/portlet.
In order to actually send data to it you'll have to have actionURL, which you can create using for example portlet:actionURL tag:
<portlet:actionURL /> or with Java code PortletURL actionUrl = portletResponse.createActionURL();
Then just submit your form using POST to this URL, and in actionRequest you'll have your parameters.
i have a form with 2 buttons let say A & B.
The required fields are depending on the button pressed.
Im using actually a DataBinder allowing me to specify requiredFields but for all actions.
How can i customize the required fields that will be depending on the button pressed ?
Thanks in advance
If you use <input type="submit" name="button1" value="Click me!" /> you can check for that button1 value in your form and then use different validation rules within your validator. You just have to extend your binding model according to these button names and to give your two buttons different names. Note that this doesn't work with <button type="submit"> in most IE versions and therefor input[type=submit] is the better choice here :-)
