Single Category Title Outside The Loop

This is from the codex for another template tag:

Use OUTSIDE The Loop

Normally, this tag must be used inside The Loop because it depends on a WordPress PHP variable ($post) that is assigned a value only when The Loop runs. However, you can manually assign this variable and then use the tag just fine.

I wonder if it works for get_the_category() as well. I can’t see why it shuldn’t. Let me know =)

See the Replace With examples here:

http://codex.ww.wp.xz.cn/Template_Tags/the_category_head

To get the categor(y|ies) outside The Loop on a single post page, use something like the following when certain of a single category:

<?php
global $post;
$category = get_the_category($post->ID);
echo $category[0]->name; // first category name
?>

or when the possibility of two or more categories exists:

<?php
global $post;
foreach(get_the_category($post->ID) as $category) {
    echo $category->name . ' ';
}
?>

Kafkaesqui,

Thank you for this code;

<?php
global $post;
foreach(get_the_category($post->ID) as $category) {
    echo $category->name . ',';
}
?>

How would you assign “echo $category->name . ‘ ‘;” to another variable so it could be used in another PHP function?

For example:
-If I have two cateogories: Stocks and Funds
-And the echo outputs: Stocks,Funds
-Can I assign this to antoher field like: $myWordpressCategory so $myWordpressCategory=”Stocks,Funds” and I can use this in another PHP function.

I’ve tried: $myWordpressCategory = $category->cat_name . ‘,’; but it only returns the last category.

Thank you,
Steve
