  It is shown here that the zero mode of any form field can be trapped to the
brane using the model proposed by Ghoroku and Nakamura. We start proven that
the equations of motion can be obtained without splitting the field in even and
odd parts. The massive and tachyonic cases are studied revealing that this
mechanism only traps the zero mode. The result is then generalized to thick
branes. In this scenario, the use of a delta like interaction of the quadratic
term is necessary leading to a "mixed" potential with singular and smooth
contributions. It is also shown that all forms produces an effective theory in
the brane without gauge fixing. The existence of resonances with the transfer
matrix method is then discussed. With this we analyze the resonances and look
for peaks indicating the existence of unstable modes. Curiously no resonances
are found in opposition of other models in the literature. Finally we find
analytical solutions for arbitrary $p-$forms when a specific kind of smooth
scenario is considered.
