Preventing editing of pages with certain IDs - wordpress

Question

I have created this plugin to prevent certain posts being deleted.
This plugin removes the TRASH option from the page list.
register_activation_hook( __FILE__, 'prevent_page_delete_activate' );
function prevent_page_delete_activate() {
add_action('admin_menu', 'prevent_page_delete');
}
add_filter ('user_has_cap', 'prevent_default_theme_deletion', 10, 3);
function prevent_default_theme_deletion($allcaps, $caps, $args) {
$ids = [2000,2333,4444];
// trash will ve removed for this page IDs
$numElementos = count($ids);
for ($i=0; $i < $numElementos; $i++) {
$post_id = $ids[$i];
if ( isset( $args[0] ) && isset( $args[2] ) && $args[2] == $post_id && $args[0] == 'delete_post' ) {
$allcaps[ $caps[0] ] = false;
}
}
return $allcaps;
}
What would be the equivalent to remove the EDIT link from certain page ids?

Answer 1

As per your last comment, there is a few thing to consider:
Visually hiding any hints to edit/delete ... etc.
Removing any default link styling.
Preventing direct access.
Preventing database update.
You can intercept the post edit via the pre_post_update action hook which fires immediately before an existing post is updated in the database..
We can use post_row_actions which filters the array of row action links on the Posts list table to prevent edits actions.
Finally we use the admin_head-{$hook_suffix} hook to remove any visual style and prevent the direct access through URL.
Everything is wrapped up in a single class to make it easier.

By the way, deleting a post is considered an edit.
You don't need your prevent_default_theme_deletion() function.
You could be tempted to use the edit_post action hook tho this wouldn't work because:
edit_post: Fires once an existing post has been updated.
The "once" statement is why we need to use pre_post_update.
pre_post_update: Fires immediately before an existing post is updated in the database.
