We want to add Support Helpdesk to Product Description pages, which can be possible only if we can insert Support Helpdesk code in custom block and include that custom block in product description pages.
 
Can someone help in this regards, on how can we include Support Helpdesk code in CUSTOM BLOCK ?
 
What is the code that should be included ?

Allow the php code in custom blocks via global admin and then copy the code from block_support.php into a custom block and then paste that into a custom block. You will then be able to put that block on any page.
 
Remember, the helpdesk block is wide, so wouldn't work on a side block if that's what you're looking to do, however I think this should be able to assist you...
 
Why don't you just put a link or an image saying, contact support or something in a block on the side of your pages. Would probably look cleaner to the customer.

Dear Dan,
 
1) We did added block_support.php code to a custom block and included that block on Product Details Page, but it showed a blank block.
 
2) We have also activated "Allow to run PHP code" from global setting.
 
As of now, it is showing a blank block on front end website.
 
Can you Please throw some light on it, or try it out & let us know.

I will try it out and get back with you by day's end (hopefully)

Okay, I gave you bad information in my email. You need to get it from the templates folder, and will have to modify it a little bit to format your needs:

Dan,
you simply posted block_support.html code, which won't work
I already tried that, it shows broken tables
 
Can someone post fully working code ?
