Hi,

i have a list with persons, every person is a k2 element and has own extrafield for email adress. In this k2 template i created in item.php a small contact form with ajax, this form has also in the same folder ajax_form_send.php file, my question is, how can i get in this file email adress from this user because if someone do a request then he/she should receive email message?

Ok you can do this two ways.

One way is to get the email from the regular Joomla! user.
Or you can use an extrafield to be filled alongside with the item.

Which way can you recommend? How can i get right email in ajax file?

If the AJAX file is within the K2 template and you are using Joomla!'s API to include it I recommend getting the Joomla! user's email.

Ma ajax file is in my k2 template for this section (in overrides), can you tell me please how can i load here joomla framework and k2 settings? I mean what's of code needed?

Thanke you in advance.

You can use this to load the contact form:

Sorry, but my last question, i need only to add this in my ajax file and i will can get normaly extrafield data?

I see now after inserting this rows error message:
Fatal error: Using $this when not in object context in PATH\form_ajax.php on line 11

This is a bad practice. Do not add custom files inside the CMS. A custom file is not aware of the Joomla! framework. This means that you will have implement most things from scratch. This also means that you need to pay more attention on the security part. Instead doing that you can write a very basic, simple component to handle the ajax task of sending an email. You can take a read at docs.joomla.org/J3.x:Developing_a_MVC_Component/Developing_a_Basic_Component to see how you can create a really simple component.

yes, but i can not implement any other component in my k2 page, right? Can you please if possible give me reply for above question?

You can also implement a K2 plugin, or you can search for an extension at the JED or getk2.org/extend
