Hello again
I tryed different things and here my solution so far:
Basically the best info I found was after searching the web for something like "display tags on post page wordpress".
What I found was that some changes have to be made in the "function.php" file which can be found in WP->Appearance->Theme File Editor.
The changes where some code (probably java?) Here an example, which worked for me (after some modifications). What I did here was generate a list of "sub-categories" of a certain "main-category" to be shown on a project page itself.
function getWorkCatList() {
global $post;
$args = array('parent' => 1);
$categories = get_categories( $args );
$categoryOutput = [];
if (!empty($categories)) {
array_push($categoryOutput, '<ul class="_Default">');
foreach($categories as $category) {
array_push($categoryOutput, '<a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '>' . $category->name.'</a> </br> ');
}
array_push($categoryOutput, '</ul>');
}
return implode('', $categoryOutput);
}
add_shortcode('work_cats_pg', 'getWorkCatList');
Explaining:
$args = array('parent' => 1); <== Here manually input the id of the "main-category"
array_push($categoryOutput, '<ul class="_Default">'); <== Here manually indicate which Text Format to use
array_push($categoryOutput, '<a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '>' . <== Here generating a clickable link to the sub-category page itself.
add_shortcode('work_cats_pg', 'getWorkCatList'); <== Finally defining the Shortcode. The list of project-related categorys can be inserted on any page by using following shortcode: [work_cats_pg]
The aim of all this? Less repetitive work with every new project which is posted. And projects basically show up anywhere where the user clicks a link. ;P
If anybody sees a better solution to all this feel free to post it. I just arrived here through trial and error - probably there are more efficient solutions out there.
One last question: Are the changes made in the "functions.php" file permanent? Hope to not crash my site with the next update.
Best regards,
Amadeus
