I am developing a site to sell some beverages to retail customers and wholesale customers.

I want to keep a log in form in landing page which help both customers to access site according their customer type (retail or wholesale)

I used member:log in_form and check my member_group.  It is “1” because I already log in into my system.

Is this possible in EE:  Create a Button for retail and button for wholesale.  Then when a customer click a button system pick customer choice and give access to relevant member group using code snippet below.

{if member_group == 7}
  Access to Retail group
{/if: elseif member_group == 8} 
  Access to wholesale group
{if:else}
  Welcome to our site.
{/if}

If it is not possible can you please guide me to the right track. I am new to EE and I love it .
