Question

是的，这应该是非常基本的PHP，但是我不能为我的生活弄清楚为什么这不起作用。

我有一个表单，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上有一个部分实际上从数据库中提取信息并且工作正常，所以我不能看到这是一个连接问题。

db_connection.php 我已将此处的信息删除为我的数据库，但一切正确

<?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");
}


?>

的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;
}
?>

的index.php 要注意这一点，函数find_reviews（）可以工作并从数据库中获取信息。以上＆＃34; db_connection.php＆＃34;和＆＃34; functions.php＆＃34;在index.php

中是必需的

<?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，所以任何人都可以看到我做错了吗？就像提交表单时一样，它只是不插入数据库。

修改::

当我尝试echo mysqli-＆gt;错误;我得到以下错误：

 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＆＃34;你好＆＃34;所以它表明我甚至没有进入它处理帖子字段的部分

自行决定:::::

我修好了，我改变了行动=＆＃34; index.php＆＃34;行动=＆＃34;＆＃34;

我不明白，它应该有效，但由于某种原因，行动空白有效。两者都应该可以接受！

Answer 1

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

Answer 2

设置为

的表单操作

 <form action="index.php" method="POST">

不起作用，但我不明白为什么不能引用当前页面。

然而，将其更改为可以解决问题。

 <form action="" method="POST">

Answer 3

嗯，你在相同的文件中得到了php，这也许就是为什么action =“”如果它默认为同一页面就行了.action =“index.php”应该在前面加上当前的网址。也许尝试将完整的网址放在action =“index.php的url”中，看看是否有效。如果是，则action =“index.php”不得转到正确的文件。
