ViewHelper that outputs a CSRF token which is required for "unsafe" requests (e.g. POST, PUT, DELETE, ...).

Note: You won't need this ViewHelper if you use the Form ViewHelper, because that creates a hidden field with the CSRF token for unsafe requests automatically. This ViewHelper is mainly useful in conjunction with AJAX.

Now, the CSRF token can be extracted via JavaScript to be appended to requests, for example with jQuery: jQuery (exemplary): $.ajax({ url: '', type: 'POST', data: {

__csrfToken: $('#someDiv').attr('data-csrf-token')

} });
