Fatal error: Call to undefined function ik_add_to_cart() in /Applications/MAMP/htdocs/333/wp-content/themes/my-shop/includes/forms/step3.php on line 51

On line 51 I have the following line of code:

ik_cart_error = ik_add_to_cart($post_id, $advals['cp_sys_total_ad_cost'], $advals['cat']);

The function does exist inside a plugin. This line is written inside the theme to add items to a shopping cart before continuing with purchase. The plugin was not written by myself, but the original author has gone awol, so no way of getting them to fix it for me and I have no idea how to fix it myself.

Working in Wordpress 3.8.2 - there was no error, but since the upgrade to 4.0 I am getting this error.

Can anyone help? Maybe an if (function_exists... or if (isset... somehow?

Thank you for your help.

Any one have any clues how to fix this line of code?

if (function_exists....?

I suspect you're more likely to get a fast/good response on a WordPress-specific forum or by contacting the plugin author. From a general viewpoint, you need to include (require) whatever file defines that function. If your error reporting is only showing fatal errors, you may want to have it also display notices/warnings in case there's any useful info there (e.g. about an include file not loading).

Yes,

if (function_exsts('ik_add_to_cart')) {
  // &#8230;
}

will help you determine, whether the function is defined and available in the scope you're in.

Warnings and notices are on.

if (function_exsts('ik_add_to_cart')) {
  // …
}

Thanks, I did try that already, but to no avail 🙁

I didn't know why I wasn't informed that you two had posted in here. I did request to be notified. Oh well...

I have to second that it feels like notifications here have been a little funky lately …
