[Solved] why i have this Some of field value is invalid

@highlander926,

Please edit the "Email" filed and set not-required using the according option, then delete all caches and check again. 

More info here: https://wpdiscuz.com/docs/wpdiscuz-7/getting-started/manage-comment-forms/comment-form-builder/#comment_form_fields

thank you for this guide

but I have the same error after doing your settings

I tried to disable ReCaptcha and set not required for email and name field

and try in cache disabled mode

but same error still exists

@highlander926,

You should find some way to insert random email addresses for registered users, otherwise wpDiscuz will not work. Please note wpDiscuz gets the email address from WordPress wp_users table. As far as in your case the filed's value (email) is missing you see that error. 

@asti  TnX for help, I am not a technical person to solve this by code

nowadays many sites are switching to SMS and OTP login/registration

so can you please help me with generating random email for all users?any script or code guide?

and fix the problem with OTP sites in your next releases if possible because we love to use your plugin

thank you

@highlander926,

Please try this code. Put the code in your current active WordPress theme functions.php file. 

add_action("user_register", function ($user_id) {
    $user = get_userdata($user_id);
    if (empty($user->data->user_email)) {
        $args = array(
            "ID"         => $user->id,
            "user_email" => uniqid() . "@example.com",
        );
        wp_update_user( $args );
    }
});

How to Easily Add Custom Code in WordPress (without Breaking Your Site).

The code above will work only for the new users. For old users you should edit the users and add some random email address. 

@asti that work, tnx
