How to create a custom button for a JIRA issue ?

[Komail Badami]

I want to be able to create a custom button for a JIRA issue and have it placed like a transition button.  How can I do this ?

After I create this button , on click I would want to be able to perform some checks on fields/subtasks/links of the issue and update certain fields. If  custom button creation is possible, how do I go about checking and updating the items I mentioned.

Thanks

Why don't you use a transition?  It could go back to the same status if you needed it too, and include a screen for the user, validators and post-functions.

If that won't work for you, then you'll need to find or write an add-on which can implement a simple web-fragment to provide the button and lead on to any forms and processes you code for.

Thanks . I think I'll just loopback to the same state using a transition. 

Will explore more about web-fragments sometime as well.
