How to use

If you want to use this parameters, you need to add them on your view:

add parameter

You can add only parameter you need:

After it you need to set this parameters on page when you insert a view on it:

You can set different parameters on different pages, if you use several captcha forms.

If you want to use the same parameters on all pages and all captchas on your site, you can set this parameters like Custom fields (in Site Settings) instead of to set them in view:

About some parameters

You must set all parameters without quotes.

1) Captcha_Type

Values: 1 or 2

Type 1 -   Type 2 -

2) Captcha_WarpFactor - distortion factor of captcha code (only type 1).

3) Captcha_IncludeUserInfo. Only on feedback-form. If true, user information (IP, Agent) will be include into letter.

4) Captcha_FieldsForValidation and Captcha_ValidationMessage. This parameters work only on feedback-form.

For validation your form you can use default validation in kooboo (for example: data-val-required="Title is required" data-val="true"). But in IE6-8 it's not working. You can use parameters - Captcha_FieldsForValidation and Captcha_ValidationMessage.

If you use "Captcha_FieldsForValidation" and "Captcha_ValidationMessage", plugin will validate fields you write ("required validation") and return to you message that you write in "Captcha_ValidationMessage".
For example, you want to validate field "name". You must write it in  "Captcha_FieldsForValidation" parameter. Also you set the "Captcha_ValidationMessage" parameter like "{0} is required". And then you can insert this message (@ViewData["name"]) into your view:

<input type="text" id="name" name="name" /> @ViewData["name"]

If user submit empty data, he'll see:
