Hi,
do i need to create the google map custom fields or are they already there?
You need to create it.
can i simply do a new import?
Yes but you need to import also latitude and longitude, otherwise users will not show on map module.
or will i then lose the other field data by clicking overwrite existing users - ie if i do a new import should i have all the original fields in there too?
When user already exists all imported data will be overwritten. If you import only some field then others fields will not be modified when user already exists.
what is the fieldalias please?
See screenshot, for example if your Google Map field have alias "gaddress" then you need to import these columns "gaddress", "gaddress_lat", "gaddress_lng". gaddress_lat is latitude, gaddress_lng is longitude.
also where do i download the google maps module please?
User Map Module is already included in Easy Profile Pro package, you can manage this as all Joomla Modules
also is the group id the id of the group i create in joomla for the two sets of users i want to display?
You can see ID of usergroups from Administration->Users->Groups, in usergroups table there is a column ID
ie i create two modules and one show group id1 and the other shows groupid2
You need to create 2 modules, one for each your usergroup.
ive never worked with sql so im hopign you mean that i do all this within the module itself not working in the db?
You need to put in SQL Custom Where this code:
in map module 1, I assumed group1 have id equal to 10
group_id IN ( 10 )
in map module 2, I assumed group2 have id equal to 11
group_id IN ( 11 )
