PHP和MySQL的语法错误

我register.php不会查询的查询简单：PHP和MySQL的语法错误

<?php 
session_start(); 

/* Connect and Query database "accounts", then close connection */ 
$connection=mysql_connect("localhost","root",""); 
if (!$connection) 
{ 
    die('Cannot connect to MySQL. Error: ' . mysql_error()); 
} 

$check_database = mysql_select_db("accounts", $connection); 
if (!$check_database) 
{ 
    die('Cannot connect to database. Error: ' . mysql_error()); 
} 

/* Query database to save user's post */ 
/* If field "repostid=0", then the post is not a repost; if the field "repostid>0", then the post is a repost with the field linking to the id of the post to be reposted */ 
$result = mysql_query("INSERT INTO posts2 (from) VALUES ('h1')"); 
if (!$result) 
{ 
    die('Cannot query. Error: ' . mysql_error()); 
} 

/* Close Connection */ 
mysql_close($connection); 

/* Redirect to user's page */ 
header("Location: /website/index.php", 404); 
exit(); 

?>

下面是回显的错误消息：

Cannot query. Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'from) VALUES ('h1')' at line 1

它从一种叫做在post.php中：

<form name="postForm" action="userpost.php" method="post" enctype="multipart/form-data" onsubmit="validatePostForm()"> 
     <div id="posttext"><p>Enter the text you wish to post, then press "Post":</p></div> 
     <div id="posttextarea"><textarea rows="10" cols="80" name="postinfo" onkeydown="characterTyping('postbuttoncharactersleft')"></textarea></div> 
     <div id="postbutton"><input type="submit" value="Post"/></div><p id="postbuttoncharactersleft">250</p><p id="postbuttoncharacterslefttext"> characters left.</p> 
    </form>

下面是数据库中的表，所以你可以确认它是查询该表正确的语法：

你需要逃避reserved words in MySQL像from与反引号

INSERT INTO posts2 (`from`) VALUES ('h1')

我其实打了一个保留字？有什么机会......我觉得很愚蠢。谢谢！ –

@shawna以供参考：http：//dev.mysql.com/doc/refman/5.6/en/reserved-words.html –

添加;在SQL语句的结束以及PHP的线的末端，这样

$result = mysql_query("INSERT INTO posts2 (`from`) VALUES ('h1');");

这里是SQL插入的例子：

INSERT INTO客户（客户名称，城市，国家）VALUES（ '红衣主教'，'斯塔万格'，'挪威'）;

你也不必把分号放在查询那样，它没有它的工作 –
