why does edit type and add node have same form_id

ooops.. typos

should have read:

why does this:

node/add/content_my_type

have the same $form_id as:

admin/node/types/content_my_type/fields

i have a type called content_product

i do form_alter when adding a node of this type but the code is trying to run on the manage fields page as well since it seems they both have same form_id.. work around is easy; just thought it was odd they would have same id..

i do this in my module:

function example_form_alter (....) {
switch ($form_id) { 

        case 'content_product_node_form':
            if (arg(0) == 'admin') break;   // need to add this to skip admin pages like manage fields
            
           [ do the code here that i want for form_alter when adding node ]
        break;
}
}
