How to retrieve parent page's $node variable in a block using module_invoke()?

I'm using module_invoke() to include a block and I need in this block to read a value contained in my parent content type page. So how can I get the $node variable in my block from the view?

Code I'm using:

<?php
    $block = module_invoke('my_blocks', 'block', 'view', 7);
    print $block['content'];
?>

Now I need to access $node in "my_blocks" and the variable is empty. What can I do to get it?

Thanks a lot for any help!

Regards

Solution

  • little fix to drupal way:

    
    function InMODULE_or_InTHEME_get_current_node() {
      if ((arg(0) == 'node') && (is_numeric(arg(1))) && (!arg(2))) return node_load(arg(1));
      return null;
    }

    Comments: node_load cache nodes, so don't worry about perfomance.
    "!arg(2)" is checking for just you don't in node edit mode (or something like).
