How to create global category sort ?

Sorry, your question is hard to understand. Do you need a sort (IE showing categories in the proper order) or categorized content (showing only entries belonging to a specific category)?

Sorry for my English. I need to categorized content

To show categorized content, you need templates that get loaded at category URL’s. The channel entries tags on those templates will self-filter when loaded at a category url.

See this tutorial for working with one template that is loaded with and without category urls.

Ok. Thanks

Can I create a hook on call {exp:channel:entries}? And then modify the contents of the tag {exp:channel:entries} If yes - tell me, please, as it is being implemented.

For example - I intercept call of {exp:channel:entries channel="channel1"} and modify it to {exp:channel:entries channel="channel2"} ?

Thanks a lot.

Why?

Good day. I try get tagdata from {exp:channel:entries ….} and modify it. For example - in template I call {exp:channel:entries channel="channel1" limit="5"}, but in extension I modify call to {exp:channel:entries channel="channel1" limit="10"} I try to use http://eeclub.ru/docs2/development/extension_hooks/module/channel/index.html#channel_entries_tagdata For test I create extension which write to file tagdata, like

function activate_extension()
{    
    $data = array(
        'class'        => __CLASS__,
        'method'    => 'modifyExpChannelTag',
        'hook'        => 'channel_entries_tagdata',
        'settings'    => serialize($this->settings),
        'priority'    => 10,
        'version'    => $this->version,
        'enabled'    => 'y'
    );
        
    $this->EE->db->insert('extensions', $data);
}
    
function disable_extension()
{
    $this->EE->db->where('class', __CLASS__);
    $this->EE->db->delete('extensions');
}

function modifyExpChannelTag($param1, $param2)
{
    $fh = fopen("c:\\test.txt", "a+");  // I'm use windows
    fwrite($fh, var_export($param1,true)); 
    fclose($fh);
    return $param1;
}

In file I expect to see - {exp:channel:entries channel="channel1" limit="5"}, but I see another information (like as parsed page) Where is my mistake ?

You’ve totally lost me, sorry.

What’s your goal here? What content are you trying to display? What’s the purpose of the extension? Why are you not using a category-related EE tag to show categorize content?
