admin panel - How to remove "delete" button from category editing page

Question

i want to disable, hide or remove delete buttons from category page

I tried editing functions.php with no luck:

add_action('admin_head', 'hide_category_buttons');

function hide_category_buttons() {
  echo '<style>
    .taxonomy-category tr:hover .row-actions {
        visibility: hidden;
    }
  </style>';
}

Answer 1

Wordpress has a filter for action links.

apply_filters( "{$taxonomy}_row_actions", $actions, $tag );

For product_cat taxonomy:

add_filter('product_cat_row_actions', function($actions, $term) {
    unset($actions['delete']);
    return $actions;
});

There is some modification in your code, insted of this class .taxonomy-category tr:hover .row-actions apply css on this class .taxonomy-category .row-actions span.delete, it willl work.

Here is whole code.

add_action('admin_head', 'hide_category_buttons');

function hide_category_buttons() {
   echo '<style>
     .taxonomy-category .row-actions span.delete {
        visibility: hidden;
     }
   </style>';
}

Answer 3

Probably your CSS selector is wrong. You can filter the admin pages where your function runs and you can use an universal selector.

global $pagenow;   
 
if (( $pagenow == 'edit-tags.php' ) && ($_GET['taxonomy'] == 'product_cat') && 
($_GET['post_type'] == 'product') ) {
    add_action('admin_head', 'hide_category_buttons'); 
}

function hide_category_buttons() {
  echo '<style> .row-actions > .delete { display: none; }  </style>';
}
