Like this    lt  php    option     POST  taskOption      gt    The index of the   POST array is always based on the value of the name attribute of any HTML input

Depends on if the form that the select is contained in has the method set to  get  or  post    If  lt form method  get  gt  then the value of the select will be located in the super global array   GET  taskOption     If  lt form method  post  gt  then the value of the select will be located in the super global array   POST  taskOption     To store it into a variable you would     option     POST  taskOption     A good place for more information would be the PHP manual  http   php net manual en tutorial forms php

Use this way    selectOption     POST  taskOption      But it is always better to give values to your  lt option gt  tags    lt select name  taskOption  gt     lt option value  1  gt First lt  option gt     lt option value  2  gt Second lt  option gt     lt option value  3  gt Third lt  option gt   lt  select gt
