I\'m Trying to make a function, my code works but i wonder is there any way to simplify my code? with loop maybe?

Background:

I try to show data from usermeta (the usermeta from plugin)

• child_name
• child_name_1
• child_name_2
• child_name_3

and so on.. based on how much user input their children in database.

example, if user only input 2 children, meta key will be:

• child_name
• child_name_1

temporary, i limit only 3 children to input, because i can\'t simplify it.

function get_child_name(){
$user = wp_get_current_user();
$count_extra_field = $user->wppb_repeater_field_15_extra_groups_count;
$count_child = $count_extra_field + 1;
$child_name_0 = $user->child_name;
$child_name_1 = $user->child_name_1;
$child_name_2 = $user->child_name_2;
$child_names = array($child_name_0,$child_name_1,$child_name_2);
$n=0;
foreach($child_names as $child_name) {
if($n==$count_child) break;
$n++;
echo $child_name;
}
}
add_shortcode(\'child_names\', \'get_child_name\');

Above code is works, as I use it now.

but is it possible to simplify it / automate the process?

So, user can input as many children as possible.

function get_child_name(){
$user = wp_get_current_user();
$count_extra_field = $user->wppb_repeater_field_15_extra_groups_count;
$names = array();
for ( $i = 0; $i < $count_extra_field; $i++ ) {
$meta_key = \'child_name\';
$key_suffix = ( 0 === $i ) ? \'\' : \'_\' . $i ;
$meta_key .= $key_suffix;
if ( $user->$meta_key ) {
$names[] = $user->$meta_key;
}
}
if ( ! empty( $names ) ) {
foreach ( $names as $name ) {
echo $name;
}
}
}
