Change your select box options value    lt select id  cmbMake  name  Make   gt        lt option value    gt Select Manufacturer lt  option gt        lt option value  Any  gt --Any-- lt  option gt        lt option value  Toyota  gt Toyota lt  option gt        lt option value  Nissan  gt Nissan lt  option gt     lt  select gt    You cann t get the text of selected option in php  it will give only the value of selected option   EDITED    lt select id  cmbMake  name  Make   gt        lt option value  0  gt Select Manufacturer lt  option gt        lt option value  1 Any  gt --Any-- lt  option gt        lt option value  2 Toyota  gt Toyota lt  option gt        lt option value  3 Nissan  gt Nissan lt  option gt     lt  select gt    ON php file    maker   mysql real escape string   POST  Make      maker   explode      maker   echo  maker 1     give the Toyota echo  maker 0     give the key 2

you can make a jQuery onChange event to get the text from the combobox when the user select one of them    lt script gt               select          change function           var str                select option selected    each function          str       this   text                            EvaluationName   val str                 change      lt  script gt    When you select an option  it will save the text in an Input hidde     lt input type  hidden  id  EvaluationName  name  EvaluationName  value   lt     Evaluation   gt     gt    After that  when you submit the form  just catch up the value of the input   Evaluation     REQUEST  EvaluationName      Then you can do wathever you want with the text  for instance save it in a session variable and send it to other page  etc

Try with this  You will get the select box value in   POST  Make   and name will get in    POST  selected text      lt form method  POST   gt   lt label for  Manufacturer  gt  Manufacturer    lt  label gt     lt select id  cmbMake  name  Make      onchange  document getElementById  selected text   value this options this selectedIndex  text  gt        lt option value  0  gt Select Manufacturer lt  option gt        lt option value  1  gt --Any-- lt  option gt        lt option value  2  gt Toyota lt  option gt        lt option value  3  gt Nissan lt  option gt   lt  select gt   lt input type  hidden  name  selected text  id  selected text  value      gt   lt input type  submit  name  search  value  Search   gt   lt  form gt      lt  php  if isset   POST  search             makerValue     POST  Make       make value       maker   mysql real escape string   POST  selected text        get the selected text     echo  maker       gt

I agree with Ajeesh  but there are simpler ways to do this     if   maker     2        or  if   maker    2        Why am I not returning a  Toyota  value  Because the  Toyota  choice in the Selection Box would have already returned  2   which  would indicate that the selected Manufacturer in the Selection Box would be Toyota  How would the user know if the value is equal to the Toyota selection in the Selection Box  In between my example code s brackets  you would put  maker    Toyota  then echo  maker  or create a new string  like so   maketwo    Toyota  then you can echo  makertwo  I much prefer creating a new string  rather than overwriting  maker s original value   If the user selects  Nissan   will the example code take care of that as well    Yes  and no  While  Toyota  would return value  2    Nissan  would instead return value  3   The current set value that the example code is looking for is  2   which means that if the user selects  Nissan   which represents value  3   then presses  Search   the example code would not be executed  You can easily change the code to check for value  3   or value  1   which represents  --Any--   What if the user clicks  Search  while the Selection Box is set to  Select Manufacturer   How can I prevent them from doing so  To prevent them from proceeding any further  change the set value of the example code to  0   and in between the brackets  you may place your code  then after that  add return   which terminates all execution of any further code within the function   statement

You can achive this with creating new array    lt  php  array   array 1   gt   Toyota   2   gt   Nissan   3   gt   BMW     if  isset    POST  search          maker   mysql real escape string   POST  Make       echo  array  maker       gt

Put whatever you want to send to PHP in the value attribute      lt select id  cmbMake  name  Make   gt        lt option value    gt Select Manufacturer lt  option gt        lt option value  --Any--  gt --Any-- lt  option gt        lt option value  Toyota  gt Toyota lt  option gt        lt option value  Nissan  gt Nissan lt  option gt     lt  select gt    You can also omit the value attribute  It defaults to using the text   If you don t want to change the HTML  you can put an array in your PHP to translate the values    makes   array 2   gt   Toyota                  3   gt   Nissan      maker    makes   POST  Make
