Refining a custom responsive template for Joomla 2.5 + VirtueMart 3
Good afternoon!
There is a somewhat unfinished responsive template for a small store on
Joomla 2.5 + VirtueMart 3.0.12
With the plugins
Custom_Fields_For_All_3.0.1
SJ_Quickview_for_Virtuemart_2-3
Stockable Customfields
1. While creating the template and reworking the product output logic, the developer debugged only "Custom Fields For All".
As a result, custom fields of the types "General child view" and "Multi Variant" turned out to work incorrectly in the new template.
For example, the quickview window does not show the field choices, and from the product page, choosing an option redirects back to the category listing page. And from the listing, the other way round: choosing an option redirects to the product page.
2. I am also interested in some minor visual tweaks to the template. But this could be a separate project.
Budget 3,000 rubles in total, stated for both parts of the work.
Payment through Safe Deal
or on completion
(possible before migration, but after a demonstration on your host)
Knowledge of VirtueMart is a must.
Please be sure to give examples of completed projects.
