The folloing PHP will remove the Name, Email & Website and check Box from the comment form in wordpress.

Use this code to make your own plugin

You might need to edit it to add Boxes back in…

<?php
/*
Plugin Name: Get Rid of Name Email Website box

//This removes the Check box for save email address
add_filter( ‘comment_form_default_fields’, ‘tu_comment_form_hide_cookies_consent’ );
function tu_comment_form_hide_cookies_consent( $fields ) {
unset( $fields[‘cookies’] );
return $fields;
}
//This remove fields Website (url) – Name (author) – email
//Remove eg $fields[‘url’], to add the Website field back in
function remove_website_name_email_field( $fields ){
if(isset($fields[‘url’],$fields[‘author’],$fields[’email’]))
unset($fields[‘url’],$fields[‘author’],$fields[’email’]);
return $fields;
}

add_filter( ‘comment_form_default_fields’, ‘remove_website_name_email_field’ );

?>

Making a plugin is a good way to add PHP code in to your website as it will let you disabled it if needed.

It is easy to do but your must have access to your websites files using FTP or you can also use wp-file-manager Plugin to add the files.

Created a folder in wp-content/plugins/ give it a name and created a file inside it called “***.php” (replace the *** with the name you want to call the file, then go to plugins on your website and activated the plugin that shows up in the Plugins interface.

Start the plugin with…

<?php
/*
Plugin Name: This is the name of my Plugin
*/

Add the PHP code that you want to be in the plugin.

This checkbox was added in WP 4.9.6 and makes it so your comment forms are compatible with GDPR, which comes into effect on May 25th.

I definitely suggest you read up on it, as there are some pretty heavy fines if the rules aren’t followed.

If your site isn’t affected by GDPR, then you can removable adding this in to your theme’s functions.php file….  this is not recommend becouse doing this for a theme that could update can lose the code, so it is better to make a plugin.   See – How to Make a plugin

Add the following PHP ….

add_filter( ‘comment_form_default_fields’, ‘tu_comment_form_hide_cookies_consent’ );
function tu_comment_form_hide_cookies_consent( $fields ) {
unset( $fields[‘cookies’] );
return $fields;
}

If you don’t want to remove the checkbox but instead edited it use…

add_filter( ‘comment_form_default_fields’, ‘tu_comment_form_change_cookies_consent’ );
function tu_comment_form_change_cookies_consent( $fields ) {
$commenter = wp_get_current_commenter();

$consent = empty( $commenter[‘comment_author_email’] ) ? ” : ‘ checked=”checked”‘;

$fields[‘cookies’] = ‘<p class=”comment-form-cookies-consent”><input id=”wp-comment-cookies-consent” name=”wp-comment-cookies-consent” type=”checkbox” value=”yes”‘ . $consent . ‘ />’ .
‘<label for=”wp-comment-cookies-consent”>Your modified text here</label></p>’;
return $fields;
}
