Share Prestashop + Wordpress users

[PrestashopTrackglobe]

Hello everyone: 

 

For different needs I need to have a blog with wordpress installed in the root of a website and a Prestashop site / store. "What I want is that the records are only enabled by the store and that this self-clone those users in Wordpress (taking both platforms installed in the same DB is easy). 

 

Doubt you see me now because I tried to do it in different ways and no I get it correctly would be: How could get through Prestashop do auto-login on Wordpress alone with PHP (no iframes, Jquery or like a once solved this I would disconnect both platforms at once, but managed to auto-login the latter should not be so complicated. 

 

Thank you very much to all.
