表
我创建了一个表单，其中包含15个问题，答案将通过单选按钮提交。我的代码适用于5个问题，但当我增加数据库中问题字段的数量时，就不会进行插入。
不同的问题有不同的名称字段，我无法使所有单选按钮的名称相同：（
这是我的代码
<?php
//Start session
session_start();
//Include database connection details
require_once('connection/config.php');
//Array to store validation errors
//$errmsg_arr = array();
//Validation error flag
//$errflag = false;
//Connect to mysql server
$link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
if(!$link) {
echo"Not Connected";
die('Failed to connect to server: ' . mysql_error());
}
//Select database
$db = mysql_select_db(DB_DATABASE);
if(!$db) {
echo "Not Selected";
die("Unable to select database");
}
//Function to sanitize values received from the form. Prevents SQL injection
function clean($str) {
$str = @trim($str);
if(get_magic_quotes_gpc()) {
$str = stripslashes($str);
}
return mysql_real_escape_string($str);
}
//Sanitize the POST values
//$ans = clean($_POST['25rboption13']);
//If there are input validations, redirect back to the same form
/*if($errflag) {
$_SESSION['ERRMSG_ARR'] = $errmsg_arr;
session_write_close();
header("location: .php");
exit();
}
*/
//Check whether the query was successful or not
/*$ignorefield=array('submit');
$fields=array_intersect($_POST,array_flip($ignorefield));
$values=array();

最后，我发现我的答案问题是，如果我替换我的代码mysql_query（query）。。。而不是$result=mysql_query（$qry）我不知道为什么，但它工作
如下更改脚本：mysql连接：
$conn=mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_DATABASE);
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
然后
$result=mysqli_query($conn,$query);
