php - Two issues while trying to update wordpress user meta -

i have form submitting data php script. here of code in script.

foreach ($newuser_values $key => $value) {         echo $key;         echo $value;             switch ($key) {                 case "show_name":                     echo "1";                     switch ($value) {                                                case "first":                         $update_val = $current_user->user_firstname;                         break;                         case "first_initial":                         echo "hi";                         $update_val = $current_user->user_firstname . " " . substr($current_user->user_lastname,0,0) . ".";                         break;                         case "first_last":                         $update_val = $current_user->user_firstname . " " . $current_user->user_lastname;                         break;                         default:                         echo "hello";                         $update_val = $user_identity;                     }                     echo $update_val;                     update_user_meta($user_id, $show_name, $update_val);                     echo get_user_meta($user_id, $show_name);                     ...              }         } 

$newuser_values array of form info. this:

$newuser_values = $_post['edit-profile']; 

i have 2 issues here. can both seen beginning of script output (from echo statements). script output is:

show_namefirst_intital1hellotestuser1array

problem 1: can see, script prints 1 means entering case titled "show_name" of switch on $key. however, not enter case entitled "first_intial" of switch on $value. why this?

problem 2: anyway script enters default case of switch on $value , prints hello. then, prints $update_val testuser1. however, value not getting assigned user_meta because printing "array". why this?

thanks in advance. apologize if these questions simplistic. pretty new wordpress , web development.

it seems cause of first issue typo. wrote script prints

show_namefirst_intital1hellotestuser1array

so seems there typo value of $value "first_intital" instead of "first_initial" check in switch case.
