playa in a matrix inside a playa

Question

so I am trying to call a Playa (m_p_discipline) inside a Matrix (discipline_3rd_order) inside Playa (thirdorder) inside of channel:entry. I am using var=prefix to get this far. The results of my code is it lists all available playa list entries not just the ones I am trying to get. I must be close but something is off.

Thanks for looking hope you can help!

        <li>
            {thirdorder:discipline_3rd_order}
                {thirdorder:exp:playa:children field="m_p_discipline" var_prefix="matrix_disipline"}
                   {matrix_disipline:title}
                {/thirdorder:exp:playa:children}
            {/thirdorder:discipline_3rd_order}
        </li>

Answer 1

The answer according to Brandon at Pixal tonic:

You don't actually need to use {exp:playa:children} if you already have an entry or Matrix row, and you want to just loop through the Playa field's related entries. In that case you can just reference your actual Playa field's short name.

Also, Matrix supports the var_prefix= parameter as well, which is helpful when looping through Playa-within-Matrix-within-Playa.

{3rd_order_under var_prefix="thirdorder_playa"}
        {thirdorder_playa:discipline_3rd_order var_prefix="discipline_matrix"}
            {discipline_matrix:m_p_discipline var_prefix="mx_disipline_playa"}
                {mx_disipline_playa:title}         
            {/discipline_matrix:m_p_discipline}        
        {/thirdorder_playa:discipline_3rd_order}
{/3rd_order_under}

Make sense?
