As the title says, I'm considering about how to call a specific function of a plugin in a view.
For example, I have a view whose name is myView. And in this view, I import 2 plugins, they are 'plgx' and 'plgy'. Both of them have a function named myFunction.
Now I want to call myFunction function of these plugins but I don't know how to call them specifically.
Besides using different names, are there any other solutions for my problem?
Try this,
Suppose your two plugins are loaded within the view then simply access with its class name like below.
if (!class_exists('vmPSPlugin')) require(JPATH_VM_PLUGINS . DS . 'vmpsplugin.php');
JPluginHelper::importPlugin('vmshipment');
ShipmentPluginClassName :: myFunction();
second Plugin like
if (!class_exists('vmPSPlugin')) require(JPATH_VM_PLUGINS . DS . 'vmpsplugin.php');
JPluginHelper::importPlugin('vmpayment');
PaymentPlugnClassName :: myFunction();
Hope this helps..

I want to check if a livewire component exists before rendering. My program has modules and each client has some of those modules enabled. I can get the list of modules a client has with $client->getModules().
Each module can implement livewire components to enhance functions of the program. I want to render those components if they exist in the correct section of the program. For example in the user creation view, I would have this:
#foreach($client->getModules() as $module)
if( component_exists( $module . '::users.create' ) )
#livewire( $module . '::users.create' )
endif;
#endforeach
If the module implements something related to the user creation, it will have the livewire component users.create, but not all modules will enhance user creation. I need to assert the existence of the component before rendering it. I was wondering if there is something like component_exists( Component::class ), otherwise, I would love to see if someone could give me a hint in how to create it as a helper function.
You can take advantage of LivewireComponentsFinder class to check if component is in manifest :
app(LivewireComponentsFinder::class)->getManifest();
If you want to create a helper, I created laravel-helpers. So, you can create a helper like this:
function component_exists($class)
{
$manifest = app(\Livewire\LivewireComponentsFinder::class)->getManifest();
return (bool) array_search($class, $manifest);
}
Been struggling with how to do this the most optimized way possible...
I have two models: Catalog and Application.
Catalog has a field called name.
Application has a field called name.
Both have a relationship with each other.
I am struggling to find a way to create a function i could use across my Laravel application which i would pass application.id to it and it would return a $app->name value based on the following logic:
if $application->name exists, use this value as the $app->name for the $application object
otherwise, get the $catalog->name value and use it as the $app->name
Note that I would like to create a component #application() where i can simply pass the $application->id and build the display logic (theming/styling) into it.
Since i display this $app->name in many places, i would like to make it as lightweight as possible to avoid unnecessary queries.
I hope this makes sense! There are probably so many ways to go with it, i am lost at figuring out the way way to do this :(
I'm not completely sure to understand your model/DB design, but you could use a custom Helper to use that function through the whole app.
For that, you can create a simple PHP class Helper.php file in app/Http/Helpers folder or whatever location you want. Something like:
<?php
use App\Catalog;
use App\Application;
if (! function_exists('getAppName')) {
function getAppName($id){
// Do your logic here to return the name
$catalog = Catalog::find($id);
return $catalog->name;
}
}
?>
Then in any controller or view, you just do
getAppName($application->id)
Do no forget to add your helpers file to the composer autoload. So in composer.json in Laravel's root folder, add the helper path to the autoload array:
"files": [
"app/Http/Helpers/helpers.php"
],
Last but not least, run the following command:
composer dump-autoload
Please note that function logic is just for sample purposes since I don't know your model structure.
In my opinion, I care about the database cost.
Use ternary expression will be elegant. But it took two times IO costs from database if application name is empty.
$app_name = Application::find($id)->name;
$app_name = empty($app_name) ? Catalog::where('application_id', $id)->first()->name;
And this will more complicated, but the catalog_query only execute when application.name is empty, it execute in database and the result is taken out only once;
And Database will only find the name from one table or two table.
Something like this:
$catalog_query = Catalog::where('catalogs.application_id', $id)->select('catalogs.name')->groupBy('catalogs.name');
// if catalogs and applications relationship is 1:1, use ->limit(1) or remove groupBy('name') is better.
Application::where("applications.id", $id)
->selectRaw("IF(application.name IS NULL OR application.name = '', (" . $catalog_query->toSql() ."), applications.name ) AS app_name")
->mergeBindings($catalog_query->getQuery())
->first()
->app_name;
Hope this will help you.
I have baked a File model and controller with default actions. Now I am trying to add an display function which can be used to show images in controlled manner.
I want to protect images so that display function can check does the user have an permissions to view image (image directory is not in a webroot).
I haven't been able to make it work, but when I started from the scratch I managed to find out that really minimal function did work.
Working function looks like this:
public function display($id) {
$this->response->file(ROOT.DS.'img'.DS.'noimage.jpg');
return $this->response;
}
When I add example:
$test=$this->File->findById($id);
to the starting of the function everything breaks.
--> http://www.example.com/files/display/1
The requested file /var/www/example.com/www/img/image.jpg was not found or not readable
Error: The requested address '/files/display/1' was not found on this server.
I have tried with debug zero, file can be found and is readable, obviously because the function without findById works.
Any ideas?

You path is totally wrong.
Did you debug() what ROOT.DS.'img'.DS.'noimage.jpg' actually holds?
I bet all the money of the world that you would probably find the solution yourself if you did
The img folder is most likely in webroot
WWW_ROOT . 'img' . DS . 'noimage.jpg'
Note that paths usually end with a DS so no need to add it again.
So if it really is an image folder in ROOT:
ROOT . 'img' . DS . 'noimage.jpg'
Also note that you can easily check if a path is valid using
file_exists()
If the file has the correct file permissions this should return true.
EDIT:
$this->File->...: File is not a good choice for a model name as it collides with the existing core class in Utility. You need to be a little bit more creative with your model naming scheme.
I am developing an Application in Bonfire.
They have extended the form helper.
Is there a way to call the original form helper from Codigniter without removing the extended one from Bonfire?
"Helpers" are just files with PHP functions in them. They aren't actually "extended", Codeigniter loads it's default helpers after loading yours, and checks if you "overwrote" a function like so:
if ( ! function_exists('form_open'))
{
function form_open() {/* default code */}
}
So unfortunately, no - there's no way to call the original function if you already declared your own.
HOWEVER: It appears that Bonfire does the exact same thing, checking with function_exists, so if you want to - you should be able to load your own form helper before it, but you still cannot simply load the original one without hacking Bonfire and removing the functions (which could have terrible side effects).
Faced the same prob, user742736's comment is the only answer that solved the prob.
Explained in detail, may be this can help some one
You can create your own helper function with out the divs surrounding the drop down here
bonfire/application/helpers/MY_form_helper.php
make a copy of the function form_dropdown, name it like form_dropdown_plain
modify the last few lines of the function to output with out divs
call form_dropdown_plain instead of form_dropdown
I had previously added Joomla modules from within Joomla articles this way : {loadmodule mod_name} but this time I need to pass parameters from it.
How can I pass parameters from within the article to a Joomla module?
You'll need to modify or clone the Joomla plugin loadmodule because it doesn't handle parameters other than just a module name. It's not particularly difficult to do if you're proficient in PHP (assuming you don't mind getting your hands dirty with a little bit of Regex work) but I'd suggest cloning it and using it this way:
Copy folder \plugins\content\loadmodule to \plugins\content\Myloadmodule (and all it's files)
Within the new folder, rename loadmodule.php and loadmodule.xml to myloadmodule.php and myloadmodule.xml. These are the files you'll do all the work on.
In both files, replace occurrences of loadmodule with myloadmodule, (Case sensitive)
In myloadmodule.php, start at around line 36 with the Regex that strips out what is in the {loadposition xxx} being processed. You'll need to tinker with this Regex to get the parameters that you want to supply when using {myloadmoduel blah-blah-blah} in your article.
Find the database entry in your table '_extensions' for loadposition and create and identical record for myloadposition. (Unless you want to write and installer)
Finally, you'll need to render the modules with your new parameters - I can't begin to help there because I don't know what modules, or parameter work you'll be doing, but this renderModule documentation will be of assistance.

I think I've covered it all, but this should be enough to get most of it done for you. When you're done, use {myloadposition ...} instead of {loadposition ...}.
I will give more details about the previous answer, to be able to pass parameters to a module with a tag as {loadmodule mod_name,param}
The solution given by GDP works fine: it's easy and quick to rewrite a content plugin (e.g. myloadmodule), following the steps 1 to 5 in the previous answer.
The problem, for me, comes with the steps 6: how to put parameters into the module, and ohow to retrieve de parameters within the module.
Step 7 : how to give parameters to the "render" of a module
In the plugin created (base on the loadmodule), you have to find the lines with the following code :
echo $renderer->render($module, $params);
Before this line, you can put parameters into the $params parameter, but "render" of the module retrieves only params with the key 'params', using a json format.
So, to pass parameters to the render function, you can do something like that :
$param = array('param_name' => 'value'); // param_name = value
$params = array('params' => json_encode($param)); // 'params' (String) should be decoded by the render of the module
echo $renderer->render($module, $params);
Step 8 : How to retrieve the parameter within the module
In the helper of your module, you can retrieve the parameter with $params variable :
$value = $params->get('param_name');
To understand a helper, read this tutorial : http://docs.joomla.org/J3.3:Creating_a_simple_module/Developing_a_Basic_Module
I googled the same issue and found your question. I know its old but my find may help someone else. There are now plugins that allow embedding modules and allowing you to pass parameters to it. My choice is Module Plant.
