I have a custom ACF field, the type is a jQuery. Its a rangeslider. The inner workings are that it over-rides a standard text input field and saves its values as either x;y (double handles) or x for single handle.
The field does everything except save its values. I’ve tried it on both posts and user profiles; backend and on a front-end form. It just won’t save its data.
No console errors.
Any help / ideas / things to try would be appreciated.
Could you give us some more information?
I take it you have created a new ACF Field type via building your own plugin?
Did you use the ‘acf-field-type-template’ ACF hosts on GitHub?
Could you log/var_dump some information about what is happening on the server at both load_value() and update_value()?
