WooCommerce add Delete Account button to My Account page This is very dangerous functionality and can cause your whole WordPress installation to break

functions.php

<?php
// Delete Account Functionality
add_action( 'woocommerce_after_my_account', 'woo_delete_account_button' );
function woo_delete_account_button() {
  ?>
	<a href="<?php echo add_query_arg( 'wc-api', 'wc-delete-account', home_url( '/' ) ) ?>" class="button">Delete Account</a>
	<?php
}

add_action( 'woocommerce_api_' . strtolower( 'wc-delete-account' ), 'woo_handle_account_delete' );
function woo_handle_account_delete() {
	// we do not want the admin to delete their account
	// advised to add more checks here to ensure you delete the correct account.
	if ( ! is_admin() ) {
		require('./wp-admin/includes/user.php');
		wp_delete_user(get_current_user_id());
	}
}
?>

There are a couple of issues with this.

1. The check to see if a user is an admin is wrong. Your check is_admin() is to see we are currently in the back end of the site.
   This is a poorly named function, and a very common mistake.

2. More importantly, this is very open to cross-site forgery attacks. Users can easily be sent a link that will delete their account once clicked.
   The solution to this to add a nonce.

Here is an example fix:
<?php // Delete Account Functionality add_action( 'woocommerce_after_my_account', 'woo_delete_account_button' ); function woo_delete_account_button() { $delete_url = add_query_arg( 'wc-api', 'wc-delete-account', home_url( '/' ) ); $delete_url = wp_nonce_url( $delete_url, 'wc_delete_user' ); ?> <a href="<?php echo $delete_url; ?>" class="button">Delete Account</a> <?php } add_action( 'woocommerce_api_' . strtolower( 'wc-delete-account' ), 'woo_handle_account_delete' ); function woo_handle_account_delete() { if ( ! current_user_can( 'manage_options' ) ) { $security_check_result = check_admin_referer( 'wc_delete_user' ); if ( $security_check_result ) { wp_delete_user( get_current_user_id() ); wp_redirect( home_url() ); die(); } } } ?>

@icreatesolutions does not work. when I click it. giving critical error

@WOLKYDJ I'd recommend adding a plugin if you need this feature.

https://wordpress.org/plugins/wp-delete-user-accounts/

https://wordpress.org/plugins/delete-me/

I don't know what happens to the orders of deleted users, so you'd want to test that.

@icreatesolutions
the error because of this code line "require('./wp-admin/includes/user.php');" If you remove it, it will fix it

@WOLKYDJ Thanks I have edited my comment.

I further added a condition for the button to not appear if the user is admin:

add_action( 'woocommerce_after_my_account', 'woo_delete_account_button' ); 
function woo_delete_account_button() { 
	$delete_url = add_query_arg( 'wc-api', 'wc-delete-account', home_url( '/' ) ); 
	$delete_url = wp_nonce_url( $delete_url, 'wc_delete_user' ); 
	?> 
	<?php if (! current_user_can( 'manage_options' )):?>
			<a href="<?php echo $delete_url; ?>" class="button">Delete Account</a> 
	<?php endif; ?>
	<?php 
} 
add_action( 'woocommerce_api_' . strtolower( 'wc-delete-account' ), 'woo_handle_account_delete' ); 

function woo_handle_account_delete() { 
	if ( ! current_user_can( 'manage_options' ) ) {
		$security_check_result = check_admin_referer( 'wc_delete_user' ); 
		if ( $security_check_result ) { 
			wp_delete_user( get_current_user_id() ); 
			wp_redirect( home_url() ); die(); 
		} 
	} 
}

Hello, how are you? How do I add this button to Edit Account only? (/account/edit-account)

How, before delete user, cancel all orders???
