i am using captcha on my custom form, it is showing properly, but i am using ajax to send data in wordpress theme, then how to include secureimage.php file to my custom class

below is my code
require_once ‘../../../plugins/securimage-wp/lib/securimage.php’; Not working showing error
Warning: require_once(../../../plugins/securimage-wp/lib/securimage.php): failed to open stream:
here is my post value, please verify the field name
print_r($securimage->check($data[‘siwp_captcha_value_0’], $data[‘input_siwp_captcha_id_0’]));

Can I use the shortcode [siwp_show_captcha] in a custom php form?

[securimage_wp] tags for contact form 7 is not working.

[securimage_wp] is only show the “[securimage_wp]”, but not captcha

First of all thank you for posting. The plugin I am looking for is the one you are having on your website. Could you please let me know what plugin are you using.???


I have problem with captcha image , its not showing

Is there a way to use the wordpress plugin and use the captcha on a custom form, not one of the wordpress forms but a form we wrote ourselves.

It seems like the instructions here has nothing to do with the wordpress plugin files.

Hi, yes it is possible to use the WordPress plugin for that. See this Github gist for using the shortcode and custom PHP to validate the captcha. Let me know if you have questions.

How to set up that error messages show on sampe page of comment ?
now after wrong code input on field wordpress take to another default page!!
I want to show messages on same page!

This is the default behavior of commenting in WordPress. Look for some Ajax comment plugins which should be able to achieve this. If the plugins are written properly, Securimage should work just fine with them as is.
