Unique photo for each parent category

  • I have a layout for https://www.theesperanzacenter.org that I’m working on. Based upon reading in the Codex and other forum posts, I came up with the following function that I had hoped would allow me to have a unique photo for each parent category. However, when I visit the archives of a sub-category, I get the following error:

    Catchable fatal error: Object of class WP_Error could not be converted to string in /home/esperanz/public_html/wp-content/themes/thesis/custom/custom_functions.php on line 66

    Line 66 of my code refers to creating the photo name plus the category_nicename (ie photo-category-nice-name.jpg).

    This is the function that I’m using:

    function image_header () {
	if (is_home() || is_front_page()) {
		$header_photo = "photo-home";
	}
	elseif (is_search()) {
		$header_photo = "photo-search";
	}
	elseif (is_category() || is_archive() || is_single()) {
			$cat = get_the_category();
			$category = get_category_parents($cat[0]->category_parent, false, '', true);
			$header_photo = "photo-".$category."";
	} else {
		$cat = get_the_category();
		$category = get_category_parents($cat[0]->category_parent, false, '', true);
		$header_photo = "photo-".$category."";
	}

	$header_photo_url = "".get_bloginfo('template_url')."/custom/images/category-headers/".$header_photo.".jpg";

echo ("<img src='."$header_photo_url".'>");

    I believe that the function that I’ve written is only pulling the current (child) category, and not the top level category.

    Can anyone offer me some advice?

    I’m answering as many noob questions as I can in hopes of someone taking a look!

    Hi!
    I’m having a similar problem, I think it’s get_category_parents(), its output is an object instead a string, I’m looking for a solution too.
    Do you find anything about?
    If not, when I’ll find the answer I’ll write you here.

    I have read again your code and I don’t think we have the same problem.
    Try var_dump($category), to see what is it, or var_dump(any other var), so you can find where is the problem.

    @manitfestcreative, you figure it out yet?

    oh I found it, insert this
    $category = get_the_category();
    $cat = $category[0]->cat_ID;
