我正在尝试使用我的MySQLi插入数据，但我总是收到错误“没有记录”。我测试了它检索数据的查询，我之前有过，但我认为问题出在prepare语句中！
我感谢任何帮助！
<?php
require 'connect.php';
require '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)) {
echo $first_name;
echo $last_name;
echo $bio;
$insert = $db-> prepare("INSERT INTO people(first_name, last_name, bio, created)
VALUES(?, ?, ?, NOW() ) ");
$insert->bind_param('sss', $first_name, $lastname, $bio);
if ($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;
}
$results->free();
}
}
//echo '<pre>', print_r($records);
?>
