You can do it like this  too    lt  php if isset   POST  select1           select1     POST  select1        switch   select1            case  value1               echo  this is value1 lt br  gt                break          case  value2               echo  value2 lt br  gt                break          default                code                break            gt     lt form action    method  post  gt       lt select name  select1  gt           lt option value  value1  gt Value 1 lt  option gt           lt option value  value2  gt Value 2 lt  option gt       lt  select gt       lt input type  submit  name  submit  value  Go   gt   lt  form gt

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

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

You can access values in the   POST array by their key    POST is an associative array  so to access taskOption you would use   POST  taskOption      Make sure to check if it exists in the   POST array before proceeding though    lt form method  post  action  process php  gt     lt select name  taskOption  gt       lt option value  first  gt First lt  option gt       lt option value  second  gt Second lt  option gt       lt option value  third  gt Third lt  option gt     lt  select gt     lt input type  submit  value  Submit the form   gt   lt  form gt    process php   lt  php     option   isset   POST  taskOption        POST  taskOption     false     if   option          echo htmlentities   POST  taskOption    ENT QUOTES   UTF-8         else        echo  task option is required        exit
