I'd like to get the module's title inside of a function in the helper.php.
$module->title
doesn't work.
I can read $module->title in the mod_xxx.php but I need this in the helper file. How to read the module title?
thanks

Long ago I used approx. 1 year it will work, try this:
$module = JModuleHelper::getModule('mod_countdown');
$moduleParams = new JRegistry($module->params);
print_r($module->title);

I need to update Task labels.
I get the task, I can step through the PodioCollection of labels ($task->labels)
I remove a label
$this->labels->remove($labelToRemove->label_id);
I add a label
$newLabel = new PodioTaskLabel();
$newLabel->text = $labelText;
$task->labels[] = $newLabel;
I then save the $task
$task->save();
The $task is saved, but the updated Task Labels are not.
The documentation here makes no sense:
https://developers.podio.com/doc/tasks/update-task-labels-151769
It says "Updates the task with new labels" at the top.
It also says you call it with:
/task/{task_id}/label/
But you call it with:
PodioTaskLabel::update( $label_id, $attributes = array() );
Huh? Why does it say in one place it is called with {task_id} but then down below, say it is called with $label_id.
In the PHP code it links to, it has this:
return Podio::put("/task/label/{$label_id}", $attributes);
Which causes me to believe the documentation is wrong.
Where in that ::update() call do I pass the task_id of the Task I want to update?
Or is there some other way to update task labels that is just undocumented?

It seems to be a bug in php client. Same code for Ruby works just great:
Podio::Task.update_labels(task_id, ['test label'])
Feel free to fix php client and submit pull request with fix.
The main goal that I want to achieve is to add a voucher code if the user has clicked on a specific external link that point to my shop.
So the (javascript?) script will analyze the url and if it contains any selected keyword will add the voucher.
Anyone knows how to do that?
Thanks
I found a pretty simple solution.
I made a module.
You can find it here: GITHUB
Was pretty easy:
Generated a basic module HERE
Selected Header Hook for my new module
Modified the header hook function in the modulename.php file in root with this one:
public function hookHeader()
{
$this->context->controller->addJS($this->_path.'/views/js/front.js');
$this->context->controller->addCSS($this->_path.'/views/css/front.css');
if (Tools::getValue('voucher')){
$cartVoucher = Tools::getValue('voucher');
$idDiscount = Discount::getIdByName($cartVoucher);
Context::getContext()->cart->addDiscount($idDiscount);
}
}
Hope will help someone.
Thanks to all.
I'm pretty new to Elixir and functional programming-languages in general.
In Elixir, I want to call one specific function on Modules, given the Module name as String.
I've got the following (very bad) code working, which pretty much does what I want to:
module_name = elem(elem(Code.eval_file("module.ex", __DIR__), 0), 1)
apply(module_name, :helloWorld, [])
This (at least as I understand it) compiles the (already compiled) module of module.ex in the current directory. I'm extracting the modules name (not as a String, don't know what data-type it actually is) out of the two tuples and run the method helloWorld on it.
There are two problems with this code:
It prints a warning like redefining module Balance. I certainly don't want that to happen in production.
AFAIK this code compiles module.ex. But as module.ex is already compiled and loaded, it don't want that to happen.
I don't need to call methods on these modules by filename, the module-name would be ok too. But it does have to by dynamic, eg. entering "Book" at the command line should, after a check whether the module exists, call the function Book.helloWorld.
Thanks.
Well, thats where asking helps: You'll figure it out yourself the minute you ask. ;)
Just using apply(String.to_existing_atom("Elixir.Module"), :helloWorld, []) now. (maybe the name "Module" isn't allowed, don't know)
Note that you always need to prefix your modules with "Elixir."
defmodule Test do
def test(text) do
IO.puts("#{text}")
end
end
apply(String.to_existing_atom("Elixir.Test"), :test, ["test"])
prints "test"
and returns {:ok}
Here is a simple explanation:
Assuming that you have a module like this:
defmodule MyNamespace.Printer do
def print_hello(name) do
IO.puts("Hello, #{name}!")
end
end
Then you have a string that hold the module name that you can pass around in your application like this:
module_name = "Elixir.MyNamespace.Printer"
Whenever you receive the string module_name, you can instantiate a module and call functions on the module like this:
module = String.to_existing_atom(module_name)
module.print_hello("John")
It will print:
Hello, John!
Another way to dynamically call the function MyNamespace.Printer.print_hello/1 is:
print_hello_func = &module.print_hello/1
print_hello_func.("Jane")
It will print:
Hello, Jane!
Or if you want to have both module_name as atom and function_name as atom, and pass them around to be executed somewhere, you can write something like this:
a_module_name = :"Elixir.MyNamespace.Printer"
a_function_name = :print_hello
Then whenever you have a_module_name and a_function_name as atoms, you can call like this:
apply(a_module_name, a_function_name, ["Jackie"])
It will print
Hello, Jackie!
Of course you can pass module_name and function_name as strings and convert them to atoms later. Or you can pass module name as atom and function as a reference to function.
Also note that the name of a module is an atom so doing String.to_existing_atom isn't usually needed. Consider this code:
defmodule T do
def first([]), do: nil
def first([h|t]), do: h
end
In this case you can simply do the apply in this fashion:
apply(T,:first,[[1,2,3]])
#=> 1
Or this example (List below is the Elixir List module):
apply(List,:first,[[1,2,3]])
#=> 1
I mean to say that if you know the name of the module, it's not necessary to pass it as a string and then convert the string to an existing atom. Simply use the name without quotation marks.
In version 18 of TextControl (http://www.textcontrol.com) there is supposed to be the ability to add background images/watermarks to the document, however I find that the behavior of the various overloads, etc is not working correctly and that the documentation is rather scarce on examples. Does any one have a working example of adding watermarks to a Word document through the ServerTextControl object?
This functionality didn't exist in previous versions, so I recognize it's still rather new, I just find it weird that doing something like
tx.Images.Add(draftImage, pageNumber, location, ImageInsertionMode.BelowTheText);
doesn't actually add the images to the document, but if I use another overload beforehand, it adds both?
I just need a loop along the lines of
foreach (TXTextControl.Page page in pages){
page.Select();
var location = tx.InputPosition.Location;
var pageNumber = page.Number;
tx.Images.Add(draftImage, pageNumber, location, ImageInsertionMode.BelowTheText);
}
where location is supposed to be the beginning of the page.
Any help would be appreciated, this should be simple!
Thank you
Finally got a response to this on their forum, it's not a complete solution, but it works for the most part. Figured I would follow up here, so that anyone who ends up on this page would get the help I wanted.

Using the HTML5 File API, I wonder if I can process the content of a file on the fly.
I know I can get the content of the file when onload is called:
function fileLoaded(e)
{
alert("content is "+e.target.result);
}
but can I get the current content when onprogress is called ?
Thanks.
Seems like yes, according to the spec. The onprogress event will fill the result property of your FileReader as more data is read in. However, as Matt pointed out, if you're only interested in a portion of the file in the first place, only read that section:
var blob = file.webkitSlice|mozSlice(startByte, stopByte, contentType);
reader.readAsBinaryString(blob);
I don't think so, but look at this example which shows you how to read slices of files.
