【问题描述】：
对，这应该是非常基本的 php，但是我一生都无法弄清楚为什么这不起作用。
我有一个表单，它在提交时应该抓取字段然后将数据插入数据库。我在我的 index.php 中有一个部分，它实际上从数据库中提取信息并且工作正常，所以我看不出这是一个连接问题。
db_connection.php 我已将此处的信息散列为我的数据库，但一切都是正确的
<?php
define("DB_SERVER","**********");
define("DB_USER","*************");
define("DB_PASS","*********");
define("DB_NAME","reviews");
$connection = mysqli_connect(DB_SERVER,DB_USER,DB_PASS,DB_NAME);
if(mysqli_connect_errno()){
die("database connection failed");
}
?>
functions.php
<?php
function redirect_to($new_location) {
header("Location: " . $new_location);
exit;
}
function confirm_query($result){
if(!$result){
die("database query failed");
}
}
function find_reviews($connection){
$query = "SELECT * ";
$query .= "FROM reviews";
$result = mysqli_query($connection,$query);
confirm_query($result);
while($reviews = mysqli_fetch_assoc($result)){
$output = "<li class=\"first\">";
$output .= $reviews["name"];
$output .= "</li>";
$output .= "<li class=\"second\">";
$output .= $reviews["company"];
$output .= "</li>";
$output .= "<li class=\"third\">";
$output .= $reviews["comment"];
$output .= "</li>";
$output .= "<li class=\"line\"></li>";
echo $output;
}
mysqli_free_result($result);
return $reviews;
}
?>
index.php 需要注意的是，函数 find_reviews() 有效并且确实从数据库中获取信息。 index.php中还需要上述“db_connection.php”和“functions.php”
<?php
require("includes/header.php");
$page_title = "All County Road Markings";
$description = "Specialising in Road Marking & Car Park Lining. We are a professional established road marking service with over 20 years experience";?>
<?php require("includes/db_connection.php"); ?>
<?php require("includes/functions.php"); ?>
<?php if(isset($_POST["submit"])){
$name = $_POST["name"];
$company = $_POST["company"];
$comment = $_POST["comment"];
$query = "INSERT INTO `reviews` (name,company,comment) VALUES ('$name','$company','$comment')";
$result=mysqli_query($connection,$query);
confirm_query($result);
redirect_to("index.php");
}
?>

好的，任何人都可以看到我做错了什么吗？就像提交表单一样，它只是没有插入到数据库中。
编辑::
当我尝试回显mysqli->错误时；我收到以下错误：
Parse error: syntax error, unexpected T_OBJECT_OPERATOR, expecting ',' or ';' in /hermes/bosoraweb140/b484/ipg.allcountyroadmarking/index.php on line 17
所以我把它改成了
if(!results){
echo "hello";
}
我没有看到“你好”，所以这表明我什至没有进入它处理帖子字段的部分
自行解决:::::
我已经修复了，我将 action="index.php" 更改为 action=""
我不明白，它应该可以工作，但由于某种原因让动作空白有效。两者都应该可以接受！
【问题讨论】：
-
您需要使用错误消息来集中您的故障排除。查询后可以
if (!$result) echo mysqli->error;并将错误添加到您的帖子中吗？ -
我的错误，应该是
(!$result) echo $connection->error;来匹配您的代码。我认为这不是问题所在，但仍然是将来调试的有用工具。
