how to insert additional data in the database when creating an item was created by doberk

Hello, I would like to load a php script right after save a new item. What I want to do is to insert additional data in the database at the same time the backend save the item information in database. I mean, save button should save the item and also run my script in order to save other data in other table in joomla database.

I was taking a look the the k2 files, but I don't know what file I have to override? Could you help me?

Thanks in advance.

You can do this with a K2 plugin.
Find here an example plugin: github.com/getk2/k2-example-plugin/blob/master/example.php

You can hook your additional actions on the

onAfterK2Save

method.

function onAfterK2Save($row, $isNew)
	{
		// Do something here
	}

Hello, I was trying to create a plugin, but it doesn't work for me. This is my plugin code:

file blogNotifyPlugin.php:

<?php

// no direct access
defined('_JEXEC') or die ;

// Load the K2 Plugin API
JLoader::register('K2Plugin', JPATH_ADMINISTRATOR.'/components/com_k2/lib/k2plugin.php');

// Initiate class to hold plugin events
class blogNotifyPlugin extends K2Plugin {
    
    public $pluginName = 'blogNotifyPlugin';
    public $pluginNameHumanReadable = 'Blog Notify Plugin';

    public function __construct(&$subject, $params){
        parent::__construct($subject, $params);
    }

    public function onAfterK2Save(&$row, $isNew){
        echo '<script>alert("onAfterK2Save event");</script>';
		die();
		return true;
    }
	
}

and file blogNotifyPlugin.xml:

<?xml version="1.0" encoding="utf-8"?>
<extension version="2.5" type="plugin" group="k2" method="upgrade">
	<name>Blog Notify Plugin</name>
	<author>Doberk</author>
	<creationDate>18/09/2018</creationDate>
	<copyright></copyright>
	<authorEmail></authorEmail>
	<authorUrl></authorUrl>
	<version>1.0</version>
	<description>test plugin</description>
	<files>
		<filename plugin="blogNotifyPlugin">blogNotifyPlugin.php</filename>
	</files>
</extension>

The plugin was installed from the backend using joomla installer, and installation worked good. The files was uploaded to /plugins/k2/blogNotifyPlugin folder. I have published the plugin with public access after installation. It should show a popup after creating new items, but nothing happens. Where am I wrong? I create new items from backend.

Thanks.

You don't see anything because a redirect (POST to GET) is performed when you save the item.

If you want to show a message after saving, then use the Joomla message API (docs.joomla.org/Display_error_messages_and_notices) for that.

That event is great when building a K2 plugin with its own DB table(s) and you want e.g. to grab the input from the K2 item form and process/save data in the database.

Thank you both. The popup was only a way to test the plugin. The real target of the plugin is to send a notification mail after a new item is published.

I have change the code according your recomendations, now the method should insert a row in a table, but still does't work, no new rows are inserted after creating items. I have checked k2 settings and I have ensured k2 plugins are enabled. I keep looking for the problem, this is the updated code of my plugin:

<?php

// no direct access
defined('_JEXEC') or die ;

// Load the K2 Plugin API
JLoader::register('K2Plugin', JPATH_ADMINISTRATOR.'/components/com_k2/lib/k2plugin.php');

// Initiate class to hold plugin events
class plgblogNotifyPlugin extends K2Plugin {
    
    public $pluginName = 'blogNotifyPlugin';
    public $pluginNameHumanReadable = 'Blog Notify Plugin';

    public function __construct(&$subject, $params){
        parent::__construct($subject, $params);
    }

    public function onAfterK2Save(&$row, $isNew){
        $query = "insert into jos_f1ld_suscripciones_blog values (null,'18/09/2018','[email protected]','0','12345')";
        $db->setQuery($query);
        $result = $db->execute();
    }
	
}

That query works good in phpmyadmin, I have checked it.

sorry, there was a mistake in the method code, no $db defined. The right code is this, now it works good.

    public function onAfterK2Save(&$row, $isNew){
        $query = "insert into `jos_f1ld_suscripciones_blog` values (null,'18/09/2018','[email protected]','0','12345')";
        $db = JFactory::getDbo();
        $db->setQuery($query);
        $result = $db->execute();
    }

Many thanks for help :)

This is an important matter, but is inexact. Following the example plugin , the class name must be PlgK2 + plugin_name. In my case, my plugin name is blogNotifyPlugin and it didn't work until the class name was PlgK2blogNotifyPlugin. I comment it in case anybody with the same problem find this thread in the future.
