javascript - Documents not being stored in full in MongoDB -

-

i working on project client. project consists of multiple pages of form inputs used online application. using nodejs , mongodb server communication , storage. online applications submitted stored in mongodb individual documents.

the problem having around 8% of these applications not being stored completely. there 162 inputs in application. reason 8% of applications storing initial input value email address. rest of inputs blank. if there problem in javascript, not affect of entries , not 8% or so?

my initial thinking user error , applicants aren't getting passed initial page, client has informed me receiving mailed paperwork accessible print if applicant completes online application in full. leads me believe mongodb culprit. don't know how can prove this. insufficient processing power on server cause kind of intermittent issue? using amazon aws m1 small instance project, inexpensive , less powerful, there on 1,200 documents in database on 3 month span, server isn't being hit hard @ all.

has else ran such problem? suggestions may have on topic appreciated. stands, don't know go here correct problem.

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
