How can I display all categories added under my custom taxonomy

I think it’s related to the way you are writing the urls.

The links of the topics should be somethink like this:
https://client.ocularconcepts.us/welead/topic/personal-leadership/

Thank you so much for help me sir

Great Sir!

But can we set this type of url
I used code for display theses

wp_list_categories( ‘taxonomy=topic&hide_empty=0&title_li=&orderby=id’ );

my permalinks setting checked Post name:

https://client.ocularconcepts.us/welead/sample-post/

if I checked custom structure and save it, it will again select Post name.

and I added a taxonomy.php in my theme

Can I redirect it to this format (https://client.ocularconcepts.us/welead/topic/personal-leadership/)
in 404.php using those term name i geeting in url?

Is it the right way?, i think its not, but can I do this?

No, that’s a wrong approach.

Where did you define the function wp_list_categories? In what file?

Sir I defined in resourcesidebar.php, in theme twentyten

using

Filter By Topic
<ul class=”search-category”>
<?php
wp_list_categories( ‘taxonomy=topic&hide_empty=0&title_li=&orderby=id’ );
?>

resourcesidebar.php is included in my category.php that displaying articles

it seems the problem is that wp_list_categories is writing the taxonomy name with the first letter capitalized. If it’s not capitalized it works ok:

https://client.ocularconcepts.us/welead/?taxonomy=topic&term=employee-motivation

But I don’t understand why it’s happening.

Try to remove the the query_var parameter when you are registering the topic taxonomy.

The possible values of query_var should be false or a string.
If you don’t define query var it defaults to taxonomy’s name.

Ok Sir, I am trying,

But I am very thanks full to you for help me,
You are such a nice person,

Thanks a lot.
I am leaving office, meet tomorrow thanks ??

Hi Sir, Good Morning,

$args=array(
  'orderby' => 'name',
  'order' => 'ASC',
  'taxonomy' => 'topic',
  'hide_empty' => 0
  );

$categories=get_categories($args);

foreach($categories as $category) {
echo '<li><a href="'.get_bloginfo('url').'/topic/'.$category->slug.'">'.$category->name.'</a></li>
';
}

I am using this code for display taxonomy.

If I want to display articles post those also associated with Topics (from custom taxonomy)

can we give the custom url for that using above code method and redirect to category page with term ID and display articles of that term ID.
(Means pass the term id in url and display articles of that topics)

Is it correct way to doing this, or any other method?

yes, you could do like that. it should work.
but did you try also to remove the query_var parameter?

Yes sir, I tried this
I removed the query_var from register_taxonomy
and I also tried to make query_var false but didn’t work, and its showing the same result as previous with first letter Caps of taxonomy etc

Thanks Sir:)

Sir,

but when we clicked on any topic its display that topic as heading
and did not activate the main navigation
like article

I wrote this for navigation

$cat = get_the_category();
$curr_cat = $cat[0]->cat_ID;

$args = array(
			'child_of' => '21',
			'hide_empty' => 0,
			'title_li'   => __( '' ),
			'current_category' => $curr_cat,
		);

wp_list_categories($args);

but i want when we are on article page and click on any topic, the article remain highlighted and display post of that article which have also selected that topic(that clicked)
