用mysql_bind_parameters语句在php中准备好的语句

Question

我正在尝试使准备好的语句起作用，但出现相同的错误。它说我正在尝试在需要mysql_stmt的地方使用布尔值。

if ($_SERVER['REQUEST_METHOD']=='POST') 
{
 {
   require('zzzx.php') ;
   $quer = 'insert into bloggert (message,email,date) values  (?,?,now()) ';
   $stmt=  mysqli_prepare($conn,$quer);
   mysqli_stmt_bind_param($stmt,'ss',$email,$message);
   //  this is where the errors start.  It always ways says it is getting a 
   // boolean rather than a mysql statement which is required
   $message= nl2br(strip_tags  ($_POST['message']));
   $auathor = strip_tags($_POST['email']);

   mysqli_stmt_execute($stmt);

   if (mysqli_stmt_affected_rows($stmt)==1)
   {
      echo '<p> the review made it to posting</p>';
   }
   else
   {
      echo '<p style = "font-weight:bold; color:#c00;"> It failed utterly.</p>';
      //this, needless to say is what I got with ever reiteration
      echo '<p>'.mysqli_stmt_error($stmt).'   </p>' ;
   }
   mysqli_stmt_close($stmt);
   mysqli_close($conn);
 }
}

问题是，我将其复制到另一个可以正常工作的文件，没问题。

此外，我注意到其他人正在使用不同的分配方式。那会成为我问题的根源吗？
