I think this may help. It has not been tested, but should be close.
The code below should be added to functions.php. Add the keywords and category names that you need to match.
// Add a categories to a post based on keywords in the title.
// Modify the $title_keywords array. Use one keyword => one category name
// Categories MUST exist first. The Post title keywords will match regardless of case.
function mam_add_category ($post_id = 0) {
if (!$post_id) return;
$title_keywords = array ( // The keywords and the corresponding category name to add
'Germany' => 'Germany',
'Phd' => 'PHD',
);
$title = get_the_title($post_id);
foreach ( $title_keywords as $keyword => $cat ) {
if ( stripos($title, $keyword) !== false ) {
$cat_id = get_cat_ID($cat);
}
if ($cat_id) {
$result = wp_set_post_terms( $post_id, $tags = $cat_id, $taxonomy = 'category', $append = true );
}
}
}
add_action('publish_post','mam_add_category');
It’s working for me, thank you for your help. i did a little modification on you code. I removed the last “,” after PHD
‘Phd’ => ‘PHD’, –> ‘Phd’ => ‘PHD’
So the right code for me is :
// Add a categories to a post based on keywords in the title.
// Modify the $title_keywords array. Use one keyword => one category name
// Categories MUST exist first. The Post title keywords will match regardless of case.
function mam_add_category ($post_id = 0) {
if (!$post_id) return;
$title_keywords = array ( // The keywords and the corresponding category name to add
'Germany' => 'Germany',
'Phd' => 'PHD'
);
$title = get_the_title($post_id);
foreach ( $title_keywords as $keyword => $cat ) {
if ( stripos($title, $keyword) !== false ) {
$cat_id = get_cat_ID($cat);
}
if ($cat_id) {
$result = wp_set_post_terms( $post_id, $tags = $cat_id, $taxonomy = 'category', $append = true );
}
}
}
add_action('publish_post','mam_add_category');

Next step is create a page in the back office to add keywords in the backoffice. 🙂
