wordpress get the current category id name and slug
This gets and displays the current category id in a wordpress blog post if you have the current id, if not you can leave the $post_id blank and it should see if there is a category loaded to the current post if there is one.
This should return an array.
Also i had to switch the the_ID(); for get_the_id(); or it just echos the post id in the middle of the page
PHP
$category_array = get_the_category( $post_id );
var_dump($category_array ); // this should show you an array of the category details
// get the primary category by grabbing the 1st bit of the array, not tested if the 1st part is actually the primary category.
$category_id = $category_array[0]['term_id'];
$category_name = $category_array[0]['name'];
$category_slug = $category_array[0]['slug'];
// ^^ this actually gives the error -- Uncaught Error: Cannot use object of type WP_Term as array
// so we need to access the array using -> rather than brackets as its an object i think.
// here is the working code:
$post_id = the_ID();
$category_array = get_the_category( $post_id );
$category_id = $category_array[0]->term_id;
$category_name = $category_array[0]->name;
$category_slug = $category_array[0]->slug;
var_dump($category_id);
echo "<pre>";
var_dump($category_array);
echo "</pre>";View Statistics

"Olivia, my eldest daughter, caught measles when she was seven years old. As the illness took its usual course I can remember reading to her often in bed and not feeling particularly alarmed about it. Then one morning, when she was well on the road to recovery, I was sitting on her bed showing her how to fashion little animals out of coloured pipe-cleaners, and when it came to her turn to make one herself, I noticed that her fingers and her mind were not working together and she couldn’t do anything. 'Are you feeling all right?' I asked her. 'I feel all sleepy,' she said. In an hour, she was unconscious. In twelve hours she was dead. The measles had turned into a terrible thing called measles encephalitis and there was nothing the doctors could do to save her. That was...in 1962, but even now, if a child with measles happens to develop the same deadly reaction from measles as Olivia did, there would still be nothing the doctors could do to help her. On the other hand, there is today something that parents can do to make sure that this sort of tragedy does not happen to a child of theirs. They can insist that their child is immunised against measles. ...I dedicated two of my books to Olivia, the first was ‘James and the Giant Peach’. That was when she was still alive. The second was ‘The BFG’, dedicated to her memory after she had died from measles. You will see her name at the beginning of each of these books. And I know how happy she would be if only she could know that her death had helped to save a good deal of illness and death among other children."
I just checked google books for BFG, and the dedication is there.
