我试图将我拥有的数据保存到mysql数据库中，但我很难做到这一点。首先，我在实践数据中成功地做到了这一点。问题是，当我向查询中添加所需的其他信息时，我的查询不再有效

代码是这样的。假设所有变量都有正确的对应值

<body>

<?php 


$username = "formtemplate";
$password = "admin123";
$hostname = "localhost";
$db = "practice";
$dbhandle = mysqli_connect($hostname, $username, $password, $db);

$sql = "INSERT INTO transactions (id_num, emp_name, branch, work_sched, dayoff, transaction, date_from, date_to, time_from, time_to, total, replacement, reason, pending, approve, decline, consume, paid) VALUES ( '$employeeNum', '$name', '$branch', '$workSched', '$dayoff', '$temptable', '$tempdatefrom', '$tempdateto', '$tempTimeFrom', '$tempTimeTo', '$tempTotal', '$tempReplacement', '$tempReason', 'yes', 'no', 'no', 'no', 'no')";

mysqli_query($dbhandle, $sql)

or die ( mysql_error() );

echo "success";

?>

</body>

<?php

mysql_connect("username","password","") or die("databse connected");
mysql_select_db("dbname") or die("databse not found");

$username=$_post['username'];
$password=$_post['password'];

mysqli`enter code here`_query("INSERT INTO `tablename` (`username`,`password`) VALUES ('$username','$password')");

?>

批准的varchar5

<?php

mysql_connect("username","password","") or die("databse connected");
mysql_select_db("dbname") or die("databse not found");

$username=$_post['username'];
$password=$_post['password'];

mysqli`enter code here`_query("INSERT INTO `tablename` (`username`,`password`) VALUES ('$username','$password')");

返回的错误是什么？为什么mysql\u错误与mysqli扩展？您应该将mysql\u错误更改为mysqli\u错误$dbhandle，这样您就不会混合使用mysql和mysqli。您将mysqli\u*与mysqli\u*。您不会看到任何错误，因为您调用了错误的API。谢谢大家。我还没有意识到我混合了mysqli和myslq。我也找到了我遇到错误的原因。我只是在批准栏中缺少字母d。

<?php

mysql_connect("username","password","") or die("databse connected");
mysql_select_db("dbname") or die("databse not found");

$username=$_post['username'];
$password=$_post['password'];

mysqli`enter code here`_query("INSERT INTO `tablename` (`username`,`password`) VALUES ('$username','$password')");
echo "successfully insert record";
