php, logic

hi guys,
I have 3 form fields, i need away to find out which field isset, i don't want to be using several if statements to find out which of the 3 fields have text inputted in. Note, that all 3 may have text in them. After i find out which ones have been set i can add the data to a database after following certain security phases.

             $email =  $_POST['email'];
              $firstname = $_POST['firstname'];
             $surname = $_POST['surname'];

Open in new window

e.g. of what i am trying to avoid

if((isset($email)) && (isset($firstname))&&(isset($surname))){
                     echo 'here';
              }
              if((isset($email)) && (isset($firstname))){
                     echo 'here';
              }
              
              if((isset($email)) && (isset($surname))){
                     echo 'here';
              }
..........................

You can iterate the $_POST array BEFORE assigning it to local variables, like this:

foreach($_POST as $field){
      if($field!=''){
             // do your stuff
      }else{
             // do other stuff
      }
}
