Uncaught Nette\InvalidStateException: Invalid value in $_POST/$_COOKIE in key ‘_acf_nonce’, expected string, b

Dear Sir/Madam,

I'm using Nette Forms as setup form for a other form that will show up after the first submit of the Nette form.

Uncaught Nette\InvalidStateException: Invalid value in $_POST/$_COOKIE in key ‘_acf_nonce’, expected string, boolean given.

I have same error, any solution for this?

David Grudl

It seems that some library is modifying $_COOKIE. Try to call Nette\Forms\Form::initialize() at the beginning of the script.

What is the reason you require strings in the cookie? I have a problem with a third-party plugin that writes an integer directly to the $_COOKIE.

Marek Bartoš

$_COOKIE values are supposed to come from http request cookie headers and are always string. $_COOKIE should be read-only for userland code.

janpot

I agree but found only a little evidence for that in PHP documentation – So is it possible to say never assign directly, use setcookie?

mystik

Assign cookie to $_COOKIES will not set cookie because it is array of received cookies. If you want to set cookie you must use setcookie.

Marek Bartoš

Currently not, imho it should be handled by a RFC for php-src
In the meanwhile it should be fixed on the plugin side, expectation of Nette is correct
