无法使用php将数据插入数据库

Question

I have a problem posting data in my database with a form. 我在使用表单将数据发布到数据库中时遇到问题。 Very basic stuff I'm sure but Im quite stuck :/ 我敢肯定，这是非常基本的东西，但我还是很困：/

I am able to get stuff out of my database using the select from database routine. 我可以使用select from database例程从数据库中获取内容。 So I know that the connection with the databse is probably not the problem. 因此，我知道与数据库的连接可能不是问题。

This is my 'upload.php': 这是我的“ upload.php”：

<html>
<head>
<title>Upload</title>
</head>
<body>

    <form action="action.php" method="post">

        <fieldset class="first">
             Name: 
        <input type="text" name="author" />
        Heading:
          <input type="text" name="heading" />

        Text:
        <textarea type="text" name="thecontent"> </textarea>
        </fieldset>


        <fieldset>
        <input type="submit"/> 
            </fieldset>
    </form>



</body>
</html>

And this is my 'action.php': 这是我的“ action.php”：

<html>
<head>

<title>Send!</title>
</head>

<body>

<?php

 ini_set('display_errors', 1); error_reporting(E_ALL); 

$link = mysql_connect('localhost','name','pasword')
or die ("Unable to connect"); 

$mydb = mysql_select_db('the_database',$link)
or die ("No database found"); 

$author = $_POST['author']; 
$heading = $_POST['heading'];
$thecontent = $_POST['thecontent'];

$mysql_query="INSERT INTO articles ('heading', 'author', 'content')
 VALUES ('$heading','$author','$thecontent')" or die(mysql_error());   

echo "This was send: $author $heading $thecontent <br> ";


 mysql_close()

?> 

</body>
</html>

All help would be much appreciated!! 所有帮助将不胜感激！

Thanks for all the help guys! 感谢所有的帮助！ I'm trying to use mysqli to insert the data however it's not yet working this is my new code in action.php: 我正在尝试使用mysqli插入数据，但仍无法正常工作，这是我在action.php中的新代码：

<html>
<head>

<title>Send!</title>
</head>

<body>

<?php

 ini_set('display_errors', 1); error_reporting(E_ALL); 
$DB_HOST = 'localhost';
$DB_USER = '**';
$DB_PASS = '***';
$DB_NAME = '***';
@ $db = new mysqli($DB_HOST, $DB_USER, $DB_PASS, $DB_NAME);
if (mysqli_connect_errno()) {
echo 'Error.';
exit();
}

$author = $_POST['author']; 
$heading = $_POST['heading'];
$thecontent = $_POST['thecontent'];

$query = 'INSERT INTO articles ('heading', 'author', 'content')
 VALUES ('$heading','$author','$thecontent')';   

$result = $db->query($query);
    if ($result) {
    echo $db->affected_rows."This was added.";
    } 
    else {
    echo "somethings gone very wrong.";
    }

$db->close();




?> 

</body>
</html>

Answer 1

You build the INSERT string, but you never call a method to realy INSERT the DB with it. 您构建了INSERT字符串，但从未调用过使用它真正实现对数据库的插入的方法。

Moreover, old mysql_* methods are deprecated, use PDO or mysqli API instead, see http://www.php.net/manual/en/mysqlinfo.api.choosing.php 此外，不建议使用旧的mysql_*方法，而应使用PDO或mysqli API，请参见http://www.php.net/manual/zh/mysqlinfo.api.choosing.php

See also stackoverflow post about this : mysqli or PDO - what are the pros and cons? 另请参阅关于此的stackoverflow帖子： mysqli或PDO-优缺点是什么？

Some PDO prepared statements examples with PDO : http://www.php.net/manual/en/pdo.prepare.php 有些PDO准备语句的例子与PDO ： http://www.php.net/manual/en/pdo.prepare.php

Answer 2

$mysql_query="INSERT INTO articles    ('heading', 'author', 'content')
 VALUES ('$heading','$author','$thecontent')";
mysql_query($mysql_query);
//required to run the query..

And mysql_close(); // missing :p
