php navigation list parent and child only WordPress

  • SOLVED

Hi,
I'd like to change my sidebar navigation which currently lists all ancestors to just parent and child without any siblings. I'd also like to deactivate the link on the current page in the navigation.
So for example my parent page is 'Animals' and underneath 'Animals' is 'Dog', 'Cat', 'Horse'. Under 'Dog' is 'Puppy' etc.
If I'm on 'Dog' the navigation should display the parent 'Animals' underneath 'Dog' (which is unlinked because I'm on that page) and not display 'Horse' and 'Cat'.
If I'm on 'Puppy' the navigation should display 'Animals' and 'Dog' and 'Puppy' should be unlinked.
I hope that's clear?!
The current code is:

<?php
global $post;

if ( $post->post_parent ) {
$ancestors = get_post_ancestors( $post->ID );
$parent = array_pop( $ancestors );
} else {
$parent = $post->ID;
}
?>
<ul class="g1-menu">
<?php wp_list_pages( 'title_li=&link_before=<span>&link_after=</span>&include=' . $parent ); ?>
<?php wp_list_pages( 'title_li=&link_before=<span>&link_after=</span>&child_of='. $parent ); ?>
</ul>

Hi, you can try this code:

<?php
$current = get_the_ID();
$ancestors = get_ancestors( $current, 'page' );
array_push($ancestors, $current);

$args_pages = array(
'title_li' => '',
'include' => $ancestors ,
'link_before' => '<span>',
'link_after' => '</span>',
'echo' => 0 ,
);
$list_pages = wp_list_pages( $args_pages );
$list_pages = preg_replace('/<li class="((.*)?current_page_item)"><a(.*)><span>(.*)<\/span><\/a><\/li>/i', '<li class="$1">$4</li>', $list_pages);
?>

<ul class="g1-menu">
<?php echo ($list_pages);?>
</ul>


If you want to show the children of the current page:

<?php
$current = get_the_ID();
$ancestors = get_ancestors( $current, 'page' );
array_push($ancestors, $current);

$args_pages = array(
'title_li' => '',
'include' => $ancestors ,
'link_before' => '<span>',
'link_after' => '</span>',
'echo' => 0 ,
);
$list_pages = wp_list_pages( $args_pages );
$list_pages = preg_replace('/<li class="((.*)?current_page_item)"><a(.*)><span>(.*)<\/span><\/a><\/li>/i', '<li class="$1">$4###</li>', $list_pages);


$args_childs = array(
'title_li' => '',
'child_of' => $current ,
'link_before' => '<span>',
'link_after' => '</span>',
'depth' => 1 ,
'echo' => 0 ,
);
$list_childs = wp_list_pages( $args_childs );

if(!empty($list_childs))
$list_childs = '<ul class="children">'.$list_childs.'</ul>';

$list_pages = str_replace('###', $list_childs, $list_pages);
?>

<ul class="g1-menu">
<?php echo ($list_pages);?>
</ul>

Can you try this one:


<?php $cats = get_categories('child_of='.get_query_var('cat'));

foreach ($cats as $cat) :

$args = array(
'posts_per_page' => 3, // max number of post per category
'category__in' => array($cat->term_id)
);
$my_query = new WP_Query($args);

if ($my_query->have_posts()) :
echo '<h3>'.$cat->name.'</h3>';

while ($my_query->have_posts()) : $my_query->the_post(); ?>
<?php /*general loop output; for instance: */ ?>
<a href="<?php the_permalink() ?>"><?php the_title(); ?></a> <br />

<?php endwhile; ?>

<?php else :
echo 'No Posts for '.$cat->name;
endif;

endforeach; ?>


Let me know if this worked.

Hi Ellah,
That doesn't work. This just lists my posts and categories. I have a listing of pages. Don't know if that makes a difference?

$current = '<a href="#">' .$page_title . '</a>';
if($post->post_parent) {

Hi Romel,
Thanks. I think we're getting there but not everything is showing up. If I click on say 'Animals' the children (horse, cat, dog) aren't showing up at all in the menu. The current page (unlinked) also isn't showing up in the menu. Would there be a way to display this?
Thanks.

Hi Romel,
It's definitely getting better! The children of a particular section still aren't appearing but the parents and grandparents are now. I wanted to disable the link completely if that's possible? not have the text look like a link (#).
Probably best if you see the website.

The sections I'm working on are the About section and Services.
Thanks.


Romel Apuya comments:

maybe you can replace this part

$current = '<a href="#">' .$page_title . '</a>';

to

$current = '<span">' .$page_title . '</span>';

"The children of a particular section still aren't appearing but the parents and grandparents are now."
ok ill work on it

Hi Jayaram,
It's not what I was looking for. In my scenario all the other links would disappear. But thanks anyway.
