An array of sanitized variables POSTed from the previous request.

In certain forms – for example, {{ user:login_form }} – you may encounter validation errors that will require you to resubmit your the form.

Instead of making your users re-type everything, you may use {{ old:[field_name] }} tag to display their previously-entered input values.

When using the {{ user:login_form }} to login, upon entering incorrect credentials, you will be shown the same page. You can use the {{ old:[field_name] }} tags to maintain the values like so:

{{ user:login_form }}

    {{ if errors }}
    {{ /if }}

    <input type="text" name="username" value="{{ old:username }}" />

    <input type="password" name="password" value="{{ old:password }}" />

    <button>Log in</button>

{{ /user:login_form }}
