# Modify an existing user

Create a new form and set `Post Management` as action.

You can select the user to be modified in two ways.

### Select the user from the new form modal

Choose All users in the List to populate from menu and select the User to edit, like in this example:

### Injecting uid in the shortcode

Add uid to the shortcode:

```php
[acpt_form id="e45b2639" uid="123"] // where 123 is the ID of the user  
```

This particular syntax can also be used in combination with `get_current_user_id()` function:

```php
$userId = get_current_user_id();
echo do_shortcode('[acpt_form id="e45b2639" uid="'.$userId.'"] ');

```

{% hint style="danger" %}
Be careful, if the user ID is wrong, the form will not be displayed.
{% endhint %}
