    Hello, good day

    Please can you give me a code to make this “EDIT” button/link to be a “DELETE” button

    Look at pic to see the “edit” button : https://postimg.cc/R30zwG4D

    …

    There are some moderator users that i want them to be able to only DELETE comments.. And not be able to change the comments… To avoid them changing or tampering with peoples comments

    I just want them to be able to see and delete the comment thats all.. Nothing else

    Moderator is just a user role i created… Pay no attention to it.. Its just the user role i created and gave it the “cap.ability” to edit posts.. So normally that edit link would show to anyone with that role

    ..

    My problem is:-

    If the moderator should click this “edit” link: https://postimg.cc/q6k0PbGf

    they would be taking here : https://postimg.cc/5HqRhxK0 .. To edit the comment. (OF WHICH THEY CAN CHEAT BY CHANGING THE COMMENTS)

    ….

    I only want them to be able to delete the comment: https://postimg.cc/k2YbZssB

    and not to edit it.

    Imagine if you host a riddle or quiz and ask : what is the capital of india

    And you want the moderators to only delete wrong answers and leave right answers

    -with the way it is..some moderators cld cheat for some people by changing their comments ..

    Thats what im trying to avoid

    (if there is another way around this problem, im open to it.)

    .
    …
    …

    Also: an alert before the moderator deletes comment would be nice.. Like maybe something like “ARE YOU SURE YOU WANT TO DELETE THIS COMMENT?” to avoid “mistake-deleting”

    Because i use this code in wp-config.php

    define('EMPTY_TRASH_DAYS', 0);

    …

    To stop the comments from moving to “BIN”

    Hello,

    For delete comment use the following code.

    
function buddydev_delete_comment() {

	if ( ! isset( $_GET['action'] ) || ! isset( $_GET['id'] ) || 'delete_comment' != $_GET['action'] ) {
		return;
	}

	if ( ! isset( $_GET['nonce'] ) || ! wp_verify_nonce( $_GET['nonce'], 'delete-comment' ) ) {
		return;
	}

	$comment = get_comment( $_GET['id'] );

	if ( empty( $comment ) || $comment->user_id != get_current_user_id() ) {
		return;
	}

	wp_delete_comment( $comment->comment_ID );

	wp_safe_redirect( get_permalink( $comment->comment_post_ID ) );
	exit;
}

add_action( 'template_redirect', 'buddydev_delete_comment' );

function buddydev_add_delete_comment_button() {

	if ( ! is_user_logged_in() ) {
		return;
	}

	$comment = get_comment();

	if ( $comment->user_id != get_current_user_id() ) {
		return;
	}

	$delete_url = add_query_arg( array(
		'id' => $comment->comment_ID,
		'action' => 'delete_comment',
		'nonce' => wp_create_nonce( 'delete-comment' ),
	), get_permalink( $comment->comment_post_ID ) );

	echo sprintf( '<a href=%s>%s</a>', $delete_url, __( 'Delete' ) );
}

add_filter( 'wp_list_comments_args', function( $r ) {
	$r['end-callback'] = 'buddydev_add_delete_comment_button';
	return $r;
} );

    Please check

    Regards
    Ravi

    Yes like that.. But that code gives EVERY USER the capability to DELETE THEIR OWN COMMENTS..

    1: (i don’t want all the users to be able to delete their own comments.. I want ONLY jst a specific user-role to be able to delete anyones & everyones comments.. Just like you did for the “REPLY” button on this post: https://buddydev.com/support/forums/topic/enable-thread-nested-comments-or-comment-reply-button-for-specific-user-role/#post-22177

    You used the contributor & author roles for example… Please apply the same in this case, Just Write the code so it be only the “CONTRIBUTOR” user-role that is able to delete EVERYONE’S comment that way.. and no one else apart from users with “contributor-roles” should be able to see that delete button/link..

    ….

    …
    2:

    And please can there be a confirmation message before the comment is deleted, Something like : “ARE YOU SURE YOU WANT TO DELETE THIS COMMENT” ?

    This might help with it: https://wordpress.stackexchange.com/questions/271686/add-confirmation-popup-on-move-to-trash

    Hello,

    I have modified the code now you can allow certain roles who can delete comments. I am sorry but due to lack of time, I am unable to assist you with confirm message.

    
function buddydev_delete_comment() {

	if ( ! isset( $_GET['action'] ) || ! isset( $_GET['id'] ) || 'delete_comment' != $_GET['action'] ) {
		return;
	}

	if ( ! isset( $_GET['nonce'] ) || ! wp_verify_nonce( $_GET['nonce'], 'delete-comment' ) ) {
		return;
	}

	$comment = get_comment( $_GET['id'] );

	if ( empty( $comment ) || ! buddydev_user_can_delete( get_current_user_id() ) ) {
		return;
	}

	wp_delete_comment( $comment->comment_ID );

	wp_safe_redirect( get_permalink( $comment->comment_post_ID ) );
	exit;
}

add_action( 'template_redirect', 'buddydev_delete_comment' );

function buddydev_add_delete_comment_button() {

	if ( ! is_user_logged_in() || ! buddydev_user_can_delete( get_current_user_id() ) ) {
		return;
	}

	$comment = get_comment();

	$delete_url = add_query_arg( array(
		'id' => $comment->comment_ID,
		'action' => 'delete_comment',
		'nonce' => wp_create_nonce( 'delete-comment' ),
	), get_permalink( $comment->comment_post_ID ) );

	echo sprintf( '<a href=%s>%s</a>', $delete_url, __( 'Delete' ) );
}

add_filter( 'wp_list_comments_args', function( $r ) {
	$r['end-callback'] = 'buddydev_add_delete_comment_button';
	return $r;
} );

function buddydev_user_can_delete( $user_id ) {

	if ( ! is_user_logged_in() || empty( $user_id ) ) {
		return false;
	}

	// Add roles who can delete comments
	$allowed_roles = array( 'administrator', 'editor' );

	$user_id = $user_id ? $user_id : get_current_user_id();

	$user = get_user_by( 'id', $user_id );

	$common_roles = array_intersect( $allowed_roles, $user->roles );

	if ( empty( $common_roles ) ) {
		return false;
	}

	return true;
}

    Regards
    Ravi
