DEEEMM AUTO MEMBER LEVEL

in profile_activate.php

Find

//Promotional membership
if ( getParam('enable_promotion_membership') == 'on' )
{
$memership_days = getParam('promotion_membership_days');
setMembership( $p_arr['Couple'], MEMBERSHIP_ID_PROMOTION, $memership_days, true );
}
}

add underneath

setMembership( $p_arr['ID'], MEMBERSHIP_GROUP_ID, 0, true );

Change MEMBERSHIP_GROUP_ID to the ID of the group you want members to automatically become a member of.

I have set it as below but it doesnt seem to work for me on Dolphin 7.1.5

 setMembership( $p_arr['ID'], 6, 0, true ); 

is this set right to give all new members access to this membership level (gold)

Yes, it should work, but make sure that the following setting is enabled:

Admin panel > Membership Levels > Settings > Enable Promotional Membership
