Using hooks in EE3 calling methods in extensions from modules

Question

I'm new to hooks, so pardon any ignorance in the questions...

So in my extension, (ext.staree.php), I have the following specifying the hook:

class Staree_ext
{
    public $hooks = array('channel_entries_row');
    ...

Then in the activation method, I have this:

public function activate_extension()
{
    foreach ($this->hooks as $hook)
    {
        $data = array(
            'class'     =>  __CLASS__,
            'method'    =>  'get_current_entry_id',
            'hook'      =>  $hook,
            'settings'  =>  serialize($this->settings),
            'priority'  =>  10,
            'version'   =>  $this->version,
            'enabled'   =>  'y'
        );

        // insert in database
        ee()->db->insert('extensions', $data);
    }
}

The get_current_entry_id is as follows: (Just to test right now)

public function get_current_entry_id($obj, $row)
{
    echo "<pre>";
    print_r($row);
    echo "</pre>";
    exit;
}

This gives me the following:

Array
(
    [entry_id] => 30
    [channel_id] => 5
    [forum_topic_id] => 
    [author_id] => 1
    [ip_address] => ::1
    ...

I need to get the current entry_id from my module mod.staree.php.

So inside my Staree class, I have the following method:

public function star()
{
    $testID = // (THIS is where I need the current id from the ext)    

    $test = "Static return: 1, Passed Entry Id: ".ee()->TMPL->fetch_param('entry_id').", Dynamically Pulled Entry Id: ".$testID;

    return $test;
}

I know if I pass the {entry_id} like this: {exp:staree:star entry_id="{entry_id}"}, it will work by fetching the params, but I would like to just get it from the template wherever it is.

I'm close, but not used to working with hooks. Any help would be GREAT!

Thanks.

It's not going to work how you're wanting. The template parser is first going to parse {exp:channel:entries} and output all the entries, and THEN parse your staree module. So by the time your module parses, the channel entries parser is already finished outputting all the entries it's going to output and is out of the picture, so current entry ID isn't available to the module tag. But it is available to the extension as you see there, but you're not going to be able to get it at parse time within the module.
