I have two omeka sites installed on two subdomains (with two different databases but the entries match) :
I would like to add a button on every item show page of my omeka installed on subdomain1, to link towards the same item on subdomain2.
For example, on the page subdomain1.domain.org/items/show/153, I would like to add a button that links to the page subdomain2.domain.org/items/show/153
I use the seasons theme, I guess I need to add something in the themes/seasons/items/show.php file, but I don't know how to do it.
Could anyone provide me guidance?
