[SOLVED] basic syntax help

[teknojunkey]

hi , can anyone advise me on how to get this right, i want to add an if statement.

 

print_r ($_SESSION['submitted'][30]['other'] ); //if this has a value  echo "choice 1";

print_r ($_SESSION['submitted'][31]['other'] ); //if this has a value  echo "choice 2";

 

print_r($session); this is what i get with one form filled in:

[30] => Array ( [other] => )

[31] => Array ( [other] => 70MM )

 

thanks

 

any book / pdf recomendations on php basics?

if(strlen($_SESSION['submitted'][30]['other'])) {
   echo "choice 1";
}
if(strlen($_SESSION['submitted'][31]['other'])) {
   echo "choice 2";
}

 

If you have many array keys i.e. 30,31,32,33, etc then you may want to run through a loop
