We solve the equations associated with the Lax pair of the nonlinear Schrödinger equation using a modified procedure of the squared wavefunction method. This solution, with the aid of the Darboux transformation, is used to study the soliton dynamics moving in phase-modulated lattices. It generalizes results from Sym's solution, and it can describe solitons on lattices with phase-modulated profiles as well as with flat-phase ones. We identify new effects of the phase-modulated lattices on soliton steering in comparison with the flat-phase lattices.
