PHPでMVS構造体を使用したフォーム検証

Question

valid（）およびinsert（）関数を作成しましたが、フォームの有効性を確認する方法がわかりません.i検証チェック後にのみinsert（）関数を呼び出します。 私は基本的なhtmlフォームコードを削除しました。
view.php

<?php 
include('../controller/control.php'); 
if(isset($_REQUEST['submit'])) 
{ 
    $u = $_REQUEST['fname']; 
    $p = $_REQUEST['lname']; 
    $i = $_FILES['pic']['name']; 
    $g = $_REQUEST['gender']; 
    $c = $_REQUEST['country']; 
    $s = $_REQUEST['state']; 
    $ci = $_REQUEST['city']; 
    $z = $_REQUEST['zipcode']; 
    $cno = $_REQUEST['cno'];  
    $h = $_REQUEST['hobby']; 
    $chk=""; 
    if($h) 
    { 
     foreach($h as $chk1) 
     { 
      $chk .= $chk1.","; 
     } 
    }  
    $a = $_REQUEST['address']; 
    $pdf = $_FILES['pdf']['name']; 
    move_uploaded_file($_FILES['pic']['tmp_name'],"upload/".$_FILES['pic']['name']); 
    move_uploaded_file($_FILES['pdf']['tmp_name'],"upload/".$_FILES['pdf']['name']);  
    $obj = new control(); 
    $obj->validate($u,$p,$i,$c,$s,$ci,$z,$cno,$a,$pdf); 
    $obj->insert($u,$p,$i,$g,$c,$s,$ci,$z,$cno,$chk,$a,$pdf); 
    header("location:form.php"); 
} 
?>
