How this error message looks like

Error message similar on screenshot below and will occur when you submit a form

Hidden field in your form

You need to make sure that hidden field is included in every form. That is because Laravel checks for this field’s value to make form sending secure.

You can do it in two ways, create this field manually inside your form element:

<!-- File: login.blade.php -->
<form method="POST" action="/login">
    
    <input type="text" name="username">
    <input type="password" name="password">
    {{ csrf_field() }}
    
</form>

or either by doing creating this field yourself:

<!-- File: login.blade.php -->
<form method="POST" action="/login">
    
    <input type="text" name="username">
    <input type="password" name="password">
    <input type="hidden" value="{{ csrf_token() }}">
    
</form>

Session and cookies management

You also need to make sure that your session works and cookies are saved correctly. This is needed to pass the token between the pages of your application.
