准备了mysqli语句

Question

我最近从mysql转移到mysqli，现在试图将我的代码重新格式化为mysqli。

请指导我这些陈述最新错误。

代码：

<?php 
include_once 'dbconnect.php'; 
$sample ='sample123'; // these are dummy values 
$orecip='admin';  // these are dummy values 
$omessage='test';  // these are dummy values 
$date = date('Y-m-d'); // these are dummy values 
$read='yes';   // these are dummy values 
$read1='no';   // these are dummy values 
$otitle='test';  // these are dummy values 

$insert = $MySQLi_CON->query("INSERT INTO messages (user_from, user_to, title, message, date, user_from_read, user_to_read) 
    VALUES($sample, $orecip, $otitle ,$omessage,$date,$read,$read1)"); 

print '<h3>Insert Multiple records</h3>'; 
if($insert){ 
    //return total inserted records using mysqli_affected_rows 
    print 'Success! Total ' .$MySQLi_CON->affected_rows .' rows added.<br />'; 
}else{ 
    die('Error : ('. $MySQLi_CON->errno .') '. $MySQLi_CON->error); 
} 

    ?> 

错误：

错误：在VALUES部分（1054）在 '字段列表'

未知列 'sample123' 你忘了引号，它应该看起来像这样：

$MySQLi_CON->query("INSERT INTO messages (user_from, user_to, title, message, date, user_from_read, user_to_read) 
VALUES('$sample', '$orecip', '$otitle' ,'$omessage','$date','$read','$read1')");
