Custom Page Navigation

Might look at Displaying Child pages of the current page in post format

Thanks, that’s what i was looking for, although i will need to change the format! For the case i need further help I leave this topic on “not resolved” for now, so I do not have to explain the situation again!

The code you gave me worked fine by itself in the sidebar file of my template but now that I created a plugin/widget and use the code in there the variable $content stays empty, does any other code has to be executed first before this function returns values?

Full error description:

When I include that Code snippet into my Plugin / widget the variable $post->ID stays empty / does not return any values!

Error Message

Notice: Undefined variable: post
Notice: Trying to get property of non-object

At wich point can I start using the variable post and how can I get it working in the Plugin?

How about using global $post;

and how can I make $post global at the right position without hacking the wp code?

I wont use global and until I find a way I will put my code in the Sidebar directly!

These work just fine in sidebar.php (using WordPress Default theme)

echo 'this is the current post id ' . $post->ID;
echo 'this is current page id ' . get_query_var('page_id');

I have my Code snippet in my sidebar now, it works fine as long as I am viewing a 1st level page, but it can not display the pages when I am in a child level, because then it wants to display the childs of the current child page:

$pages = get_pages('child_of='.$post->ID.'&sort_column=post_date&sort_order=desc');

How can I either display “brother_of” pages or find out the ID of the parent?

I found following as approach, how can I include the parent line

<?php $args = array(
‘child_of’ => 0,
‘sort_order’ => ‘ASC’,
‘sort_column’ => ‘post_title’,
‘hierarchical’ => 1,
‘exclude’ => ,
‘include’ => ,
‘meta_key’ => ,
‘meta_value’ => ,
‘authors’ => ,
‘parent’ => -1,
‘exclude_tree’ => ,
‘number’ => ,
‘offset’ => 0 ); ?>

Thread already moved to page 3. How can I find out the post ID of the parent page? Tried many versions of the code out of my last two posts.

<?php
$pages = get_pages('sort_column=post_date&sort_order=desc');
foreach($pages as $page) {
//echo "<pre>"; print_r($page); echo "</pre>";
echo 'page parent id ' . $page->post_parent;
}
?>

If you are doing a multi-level heirarchy and going several pages deep I’ve got a short tutorial that might help as well: https://www.vsellis.com/wordpress-how-to/wordpress-page-navigation-context-sensitive/
