Calling plugin method inside custom component

[Antanas Vipartas]

Hi, I'm developing with Joomla 1.7

I created my custom component and a content plugin. How should I call my plugin's method onContentBeforeDisplay() inside components view?

this doesn't work...
$plugin =& JPluginHelper::getPlugin('content', 'kokteiliai');
$plugin::onContentBeforeDisplay();

I think you need to trigger the event. Something like this:

$dispatcher = JDispatcher::getInstance();
$results = $dispatcher->trigger('onContentBeforeDisplay', array('com_content.article', &$item, &$this->params, $offset));

I copied that from com_content. The array are the arguments for the plugin method. You might also want to set a context in your custom component so you can easily check this in your plugin, to make sure you only execute the plugin when you are in your custom component. Hope that helps. Mark

Thanks for the solution. I have already tried that and it works.

But this method calls all content plugins which is not very good for performance optimization. I would like to execute only my custom plugin.

It should be other way to call exactly that plugin...

As I understand it, the whole idea behind plugins is that the calling event doesn't have to know what if any plugins might get called. If you just want to call a fixed method at a fixed point in the program, why use a plugin? Why not just call a method? Good luck. Mark

You're right. It's better to include that piece of code into separate function/library.

Do you know any way to include library/externa file (containing my own functions) without changing the core code?

Here is how I use custom plugins:

Typically in the view....

// Plugin params
$data = array('param1' => $items, 'param1' => $location, ....);

// Load plugin       
JPluginHelper::importPlugin('exps', 'plugin_name');
       
$dispatcher = JDispatcher::getInstance();
       
$result = $dispatcher->trigger('getMyFunction', $data);
       
$this->items = $result[0];

My custom plugins are installed in plugin folder "exps"

Typically, I use plugins to build abstract connectors (e.g. payment and shipping API's, or provide utility functions) that allow any component or module to use the API / utility without having to implement it. All the component needs to do is invoke the plugin, pass data and handle response.

I think you just put the require statements or JLoader::register statements in your code. You can also override the standard includes files if you like. If it were me, I think I would just create a single file that loads my custom stuff (using JLoader::register) and then include that file where I need it. There could be an easier way as well. Good luck. Mark
