if заявление сброс формы данных переменная

Question

Если пользователь загружает неправильный файл, то если оператор сбросит $name на пустой. В чем проблема в следующем коде?

if(isset($_POST['submit'])){ 
     $conn= new mysqli('localhost','root','','dilip'); 
     if(!$conn){ 
       die("Not connect".mysqli_error); 
     } 
     $stm = $conn->prepare("Insert into comment (Name, email, Message, Image) values (?, ?, ?, ?)"); 
     $stm->bind_param('ssss',$name,$email,$message,$image); 


     $name = $_POST['name']; 
     $message = $_POST['readerInput']; 
     $email = $_POST['email']; 
     $image='upload/comment/default.jpg'; 
     $time = date("s"); 


     //if(isset($_FILES['image'])){ 
     if(is_uploaded_file($_FILES['image']['tmp_name'])){ 
       $tmp_image = $_FILES['image']['size']; 
       $finfo = new finfo(FILEINFO_MIME_TYPE); 
       $file = $finfo->file($_FILES['image']['tmp_name']); //This line checks MIME Type of uploaded image 

       if($file!=='image/jpeg' && $file !=='image/gif' || $tmp_image > 1024*1024*2){ //1024*1024*2 = 2MB 
        echo "Upload your Profile Image in jpg/gif format and lower than 2mb. Otherwise continue without Image."; 
       } 

       else{ 

        $photo = move_uploaded_file($_FILES['image']['tmp_name'],'upload/comment/'.$name.$time.'.jpg'); 
        $image = 'upload/comment/'.$name.$time.'.jpg'; 
        echo '<script> alert("Your file is accepted.")</script>'; 
        $stm->execute(); 

        $message = 'Your Comment'; 
        $name = 'Your Name'; 
        $email = 'Your eMail'; 

       } 
    }else{ 
       $stm->execute(); 
       $message = 'Your Comment'; 
       $name = 'Your Name'; 
       $email = 'Your eMail'; 
    } 
}

Попробуйте нижеследующий фрагмент. Вы готовите инструкцию insert перед инициализацией переменной и кодом загрузки изображения. Я переместил код ниже кода загрузки файла.

if(isset($_POST['submit'])){ 
     $flag = 0; 
     $conn= new mysqli('localhost','root','','dilip'); 
     if(!$conn){ 
       die("Not connect".mysqli_error); 
     } 

     $name = $_POST['name']; 
     $message = $_POST['readerInput']; 
     $email = $_POST['email']; 
     $image='upload/comment/default.jpg'; 
     $time = date("s"); 


     //if(isset($_FILES['image'])){ 
     if(is_uploaded_file($_FILES['image']['tmp_name'])){ 
       $tmp_image = $_FILES['image']['size']; 
       $finfo = new finfo(FILEINFO_MIME_TYPE); 
       $file = $finfo->file($_FILES['image']['tmp_name']); //This line checks MIME Type of uploaded image 

       if($file!=='image/jpeg' && $file !=='image/gif' || $tmp_image > 1024*1024*2){ //1024*1024*2 = 2MB 
        echo "Upload your Profile Image in jpg/gif format and lower than 2mb. Otherwise continue without Image."; 
        $flag = 1; 
       }else{ 
        $photo = move_uploaded_file($_FILES['image']['tmp_name'],'upload/comment/'.$name.$time.'.jpg'); 
        $image = 'upload/comment/'.$name.$time.'.jpg'; 
        echo '<script> alert("Your file is accepted.")</script>'; 
       } 
    } 

    $stm = $conn->prepare("Insert into comment (Name, email, Message, Image) values (?, ?, ?, ?)"); 
    $stm->bind_param($name,$email,$message,$image); 
    if($flag==0){ 
     $stm->execute(); 
    }  
}
