Question

我正在尝试将数据插入到我的数据库中，但输入不会存储在 mysqli 中。

如果我将它插入数据库，它会显示输出正常，但是当我使用我的表单时，没有任何内容存储。一双新眼睛可以看到我做错了吗？

这是我的代码：

<?php
error_reporting(0);
require 'db/connect.php';
require 'functions/security.php';

$records = array();

if(!empty($_POST)) {
if(isset($_POST['first_name'], $_POST['last_name'], $_POST['bio'])) {

$first_name = trim($_POST['first_name']);
$last_name = trim($_POST['last_name']);
$bio = trim($_POST['bio']);

if(!empty($first_name) && !empty($last_name) && !empty($bio)) {
    $insert = $db->prepare("INSERT INTO people (first_name, last_name, bio, created) VALUES (?, ?, ?, NOW())");
    $insert->bind_param('sss', $first_name, $last_name, $bio);

    if($insert->execute()) {
        header('Location: index.php');
        die();

    }

}

}
}

if($results = $db->query("SELECT * FROM people")) {
if($results->num_rows) {
while($row = $results->fetch_object()) {
    $records[] = $row;
}
$results->free();
}
}
?>

<!DOCTYPE html>
<html>
<head>
<title>People</title>
</head>
<body>
<h3>People</h3>

<?php
if(!count($records)) {
    echo 'No records';
} else {
?>
    <table>
        <thead>
            <tr>
                <th>First name</th>
                <th>Last name</th>
                <th>Bio</th>
                <th>Created</th>
            </tr>
        </thead>
        <tbody>
        <?php
        foreach($records as $r) {
        ?>
            <tr>
                <td><?php echo escape($r->first_name); ?></td>
                <td><?php echo escape($r->last_name); ?></td>
                <td><?php echo escape($r->bio); ?></td>
                <td><?php echo escape($r->created); ?></td>
            </tr>
        <?php
        }
        ?>
        </tbody>
    </table>
   <?php
 }
 ?>

Answer 1

将name="Last_name"更改为name="last_name"，因为您的帖子$_POST['last_name']已将其设为小写
