What are the strings for other fields from the K2 items?

Hi,
on Portfolio Grid option for NSP on roll over on the image it shows the Title, Date and Author.
In controller.php I learned that this code is for the author name:

Code: Select all

// Author
if($this->parent->config['portal_mode_portfolio_grid_author'] != 0) {
   echo '<span>'.$this->parent->content[$i]['author_username'].'</span>';
}
echo '</span>';

I guess that the same way I can get the other fields even the extra fields but I cannot find out how and where is this defined. Where do you assign 'author_username' for the authors name since in the K2 item the syntax for author data is: $this->item->params->get('itemAuthor').

It has to do something with the content[$i] but not sure where to search.

Thanks,
Gorast

Hi

This is not exactly like that. Naming of variables can be a lot different between extensions and it doesn't even have to be similar.

In Your example $this->parent->content[$i]['author_username'] is just one of the values from database (query for database is located in style's modal.php) and there the naming is decided. When You will see ".. AS author_username" it's the place. Also a full list of items pulled from database with their naming will be close to this one.

Or You can simply use a method I found extremely useful and right after the piece of the code You have copied above use a construction like:

Code: Select all

print '<pre>';
var_dump( $this->parent->content[$i] );
print '</pre>';


when You will look at site after adding this code, full list of elements in $this->parent->content[$i] will be revealed.
