WHERE id=:id 

<php 
ini_set('display_startup_errors',1); 
ini_set('display_errors',1); 
error_reporting(-1); 

    require_once 'db.php'; 
    if(isset($_POST['submit'])) 
    { 
     $get_id=$_REQUEST['id']; 
     $name=$_POST['name']; 
     $surname=$_POST['surname']; 
     $pic = $_FILES['pic']['name']; 

     try{   
      move_uploaded_file($pic,"uploads/$pic"); 
      $stmt = $db_con->prepare("UPDATE posts SET 
      name=:name,surname=:surname,pic=:pic WHERE id=:GET_id"); 

      $stmt->bindParam(":id", $id); 
      $stmt->bindParam(":name", $name); 
      $stmt->bindParam(":surname", $surname); 
      $stmt->bindParam(":pic", $pic); 

       if($pic=="") {

     if($stmt->execute()) 
     { 
      echo "<script>alert('Successfully Updated!!!'); window.location='index.php'</script>"; 
     } 
     else{ 
      echo "Query Problem";

变化GET_id到id和这里在下面的代码

$id = $_REQUEST['id'];
