The Warsash talent recently told The News about his hunger to return to the Football League.
Smith is now poised to join Eastleigh, which will see him ply his trade just one division below League Two.
Bognor first-team coach Robbie Blake said: ‘Players who come to Bognor should know that they can continue to develop their football education in a team that plays an expansive game on a fantastic pitch with brilliant amenities.
‘The players who will look at Dan's progression will see how much they can add to their game by joining us.
‘They might have been released by a league cub or feel they haven't had the chance to prove their worth yet coming up through the levels.
‘One way or another I am confident that we can help them make progress and this is evident with Dan looking like he is moving to Eastleigh.’
