我正在尝试连接到数据库.html页面没有连接到addtodatabase.php，它有许多字段，如单选按钮，复选框，textarea，输入字段。一旦给定提交它不显示数据。< / p>
<form action="addtodatabase.php" method="post">
<div class="container">
<form class="form-inline">
<fieldset>
<legend>Security Department User Registration</legend>
<div class="form-group">
<label for="Firstname">First Name</label>
<input type="text" class="form-control" id="Firstname" name="Firstname" placeholder="Text input"><br/>
</div>
<div class="form-group">
<label for="Secondname">Second Name</label>
<input type="text" class="form-control" id="Secondname" name="Secondname" placeholder="Text input"><br/>
</div>
</form>
.....
...
<button type="submit" class="btn btn-default">Submit</button>
addtodatabase.php页面为phpmyadmin用户名为root，pasword为NULL
<?php
$connection = mysql_connect ('root','','');
mysql_select_db('form_db');
$Firstname = $_POST ['Firstname'];
$Secondname = $_POST ['Secondname'];
echo $_POST['Firstname'];
echo '<br />';
echo $_POST['Secondname'];
$query =
"INSERT INTO form_details
(Firstname,Secondname)
values
('$Firstname','$Secondname')";
$result = mysql_query($query);
Echo "Database Saved";
mysql_close($connection);
?>
我已将代码从mysql更改为mysqli
<?php
$connect=mysqli_connect('localhost','root','','form_db');
if(mysqli_connect_errno($connect))
{
echo 'Failed to connect';
}
$Firstname = $_POST ['Firstname'];
$Secondname =$_POST ['Secondname'];
echo $_POST['Firstname'];
echo '<br />';
echo $_POST['Secondname'];
$query =
"INSERT INTO form_details
(Firstname,Secondname)
values
('$Firstname','$Secondname')";
$result = mysqli_query($query);
if(mysqli_affected_rows($connect) > 0){
echo "<p>Employee Added</p>";
echo "<a href="index.html">Go Back</a>";
} else {
echo "Employee NOT Added<br />";
echo mysqli_error ($connect);
}
?>
即使更改为mysqli，它也无法正常工作.addtodatabase.php 我收到此错误不推荐使用：mysql_connect（）：不推荐使用mysql扩展，将来会删除：在第2行的C：\ wamp64 \ www \ Form \ addtodatabase.php中使用mysqli或PDO
我的整个表单都是这样的

我无法从form.html页面连接到addtodatabase.php。 注意：未定义的索引：第12行的C：\ wamp64 \ www \ Form \ addtodatabase.php中的firstname
答案 0 :(得分：1)
你需要传递2个参数！ $result = mysqli_query($connect, $query);
