mysql_query（INSERT ...）函数在我的代码中不工作 [英] mysql_query(INSERT ...) function not working in my code

问题描述

我创建数据库，它基本上接受
长度47的名称和回应字符串，我的PHP代码将根据我提供的答案密钥对传入结果进行评分，并且包含正确答案计数的数字存储在数据库中。这是我的数据库的信息。
数据库名称标记为
，表名为answer，其中有以下5个字段：

I've create database, which basically accept name and Id and answer string of length 47,and my php code will grade the incoming results against the answer key I provided and number containing the count of correct answers will stored in database. this is information of my database. database name is marking and table called 'answer', which has 5 fields as follow

1) answer_id :int , not null, auto increament.
2) name: text
3)id : text
4)answers : text
5)correct : int

我的问题和问题是函数是否正在工作

my question and problem is the function is working

// setup query
$q = mysql_query("INSERT INTO `answer` VALUES 
 (NULL,'$name', '$id','$answers','$correct')");
// run query
$result = mysql_query($q);

或者换句话说，没有什么存储在我的数据库中

or in another way , nothing storing in my database ???

提前感谢。

这是整个程序。

<?php
error_reporting(E_ALL ^ E_STRICT);
// to turn error reporting off 
error_reporting(0);

$name  =$_POST['name']; 
$id = $_POST['id']; 
$answers = $_POST['answers'];

// check the length of string
if(strlen($answers) !=10) 
{
print'your answer string must be 10';

return;

} 
mysql_connect("localhost","root",""); 
mysql_select_db("marking"); 
$name = addslashes($name); 
$id = addslashes($id); 
$answers =  addslashes($answers); 
$answer_key =  "abcfdbbjca"; 
$correct =  0; 
for($i=0;$i<strlen($answer_key);$i++) 
{

if($answer_key[$i]  == $answers[$i])

$correct++;

} 
 //  Setup query
$q = mysql_query("INSERT INTO `answer` VALUES ('$name', '$id','$answers','$correct')");
$result = mysql_query($q);
print 'Thnak you. You got' + $correct + 'of 10 answers correct'; 
?>

推荐答案

尝试：

// setup query
$q = "INSERT INTO `answer` (`name`, `id`, `answers`, `correct`) VALUES 
 ('$name', '$id','$answers','$correct')";

//Run Query
$result = mysql_query($q) or die(mysql_error());

此外，您应避免使用 mysql _ 函数因为他们在被废弃的过程中。相反，我建议您熟悉 PDO 。

Also, you should avoid using mysql_ functions as they are in the process of being deprecated. Instead, I recommend you familiarize yourself with PDO.

此外，注意，或die（mysql_error（））部分不应在生产代码中使用，仅用于调试目的。

Also, note, the or die(mysql_error()) portion should not be used in production code, only for debugging purposes.
