I have written a custom module where i need to sanitize (replace) filed value of a node being displayed [replacing filed value only while displaying it, and not its original content].
To accomplish this, I thought to implement hook_field ($op = 'sanitize') in my custom module but unfortunately it is not being called by drupal system. I verified it by placing drupal_set_message() at very first line of code withing hook_field(), but no luck. Again when one of module in my project (link-6.x) has hook_field() has been implemented and gets call from drupal system with no issues.
Can any one explain me, either this is a bug or I am missing someting?
Thank you.
