Question

我最近从mysql转移到mysqli，现在尝试将我的代码重新格式化为mysqli。

请指导我这些陈述的错误。

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：（1054）“字段列表”
中的未知列'sample123'

你在VALUES部分忘记了引用，它应该是这样的：

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

准备好的mysqli声明
