In the front end it already working fine, it return the url link with the taxonomy slug.
And in Cred I also have the shortcode for this taxonomy field like this :
[cred_field field='merek-mesin' display='checkboxes' urlparam='merek-mesin' output='bootstrap']
But in the front-end form I don't have any taxonomy field already pre selected at all
Is it something that I miss in the shortcode?
Fyi, the custom taxonomy slug that I am using is called "merek-mesin"
Sorry, I think I must have got my wires crossed when I replied to your earlier thread, mixing preselecting a custom field value vs preselecting a taxonomy value.
Pre-selecting a taxonomy value is not possible.
The value or urlparam attributes of the cred_field shortcode only work for custom fields, not for taxonomies.
That is an unfortunate limitation, and we have a feature request to make those attributes work the same for taxonomies as for custom fields.
Thanks for your response, so the only way is to add it using Forms API, do you mind to provide me the code for this one, because I am not very familiar with php code in the link you give me
