Question

我是PHP的新手，我一直在创建一个webapp，允许我在我的数据库中创建一个所有者，然后允许我阅读所有者。

我一直收到以下错误：

注意：未定义的变量：第26行的C：\ xampp \ htdocs \ public \ create.php中的new_owner

警告：array_keys（）期望参数1为数组，在第26行的C：\ xampp \ htdocs \ public \ create.php中给出null

警告：implode（）：在第26行的C：\ xampp \ htdocs \ public \ create.php中传递的参数无效

注意：未定义的变量：第27行的C：\ xampp \ htdocs \ public \ create.php中的new_owner

警告：array_keys（）期望参数1为数组，在第27行的C：\ xampp \ htdocs \ public \ create.php中给出null

警告：implode（）：在第27行的C：\ xampp \ htdocs \ public \ create.php中传递的参数无效

致命错误：未捕获错误：在C：\ xampp \ htdocs \ public \ create.php中调用boolean上的成员函数execute（）：31堆栈跟踪：在C：\ xampp \ htdocs中抛出＃0 {main}第31行\ public \ create.php

我的代码如下：

<?php


if (isset($_POST['submit']))
{

require "config.php";
require "common.php";

try 
{
$connection = new mysqli($host, $user, $password, $dbname, $port, $socket);

$new_user = array(
"OwnerNum" => $_POST['OwnerNum'],
"LastName"  => $_POST['LastName'],
"Address"     => $_POST['Address'],
"City"       => $_POST['City'],
"State"  => $_POST['State'],
"PostalCode"  => $_POST['PostalCode']
);

$sql = sprintf(
"INSERT INTO %s (%s) values (%s)",
"owners",
implode(", ", array_keys($new_owner)),
":" . implode(", :", array_keys($new_owner))
);

$statement = $connection->prepare($sql);
$statement->execute($new_owner);
}

catch(PDOException $error) 
{
echo $sql . "<br>" . $error->getMessage();
}

}
?>

<?php require "templates/header.php"; ?>

<?php 
if (isset($_POST['submit']) && $statement) 
{ ?>
<blockquote><?php echo $_POST['OwnerNum']; ?> successfully added.
</blockquote>
<?php 
} ?>

<h2>Add an Owner</h2>

<form method="post">
<label for="OwnerNum">OwnerNum</label>
<input type="text" name="OwnerNum" id="OwnerNum">
<label for="LastName">Last Name</label>
<input type="text" name="LastName" id="LastName">
<label for="FirstName">First Name</label>
<input type="text" name="FirstName" id="FirstName">
<label for="Address">Address</label>
<input type="text" name="Address" id="Address">
<label for="City">City</label>
<input type="text" name="City" id="City">
<label for="State">State</label>
<input type="text" name="State" id="State">
<label for="PostalCode">PostalCode</label>
<input type="PostalCode" name="PostalCode" id="PostalCode">
<input type="submit" name="submit" value="Submit">
</form>

<a href="index.php">Back to home</a>

<?php require "templates/footer.php"; ?>

PHP，创建和阅读用户
