php表单提交没有插入到数据库中

Question

是的，这应该是非常基本的 php，但我终究无法弄清楚为什么它不起作用。

我有一个表单，在提交时它应该抓取字段然后将数据插入数据库。我在我的 index.php 上有一个部分，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 我已经将这里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");
}


?>

函数.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() 起作用并确实从数据库中获取信息。 index.php 中还需要上面的“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，所以有人能看出我做错了什么吗？因为当提交表单时，它只是没有插入到数据库中。

编辑::

当我尝试 echo mysqli->error;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 

所以我改成了

if(!results){
     echo "hello";
}

而且我没有看到“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:::::

我修复了它，我将 action="index.php"更改为 action=""

我不明白，它应该有效，但由于某种原因，空白操作有效。两者都应该是可以接受的!

$_POST['submint'] 的 if 语句在每次提交时都可能为假。也许试试 !empty($_POST)
