PHP - 插入记录到SQL数据库

Question

您好我用下面的PHP代码中插入一条记录到一个SQL数据库...但代码亘古不工作..

<?php 
include_once("config.php"); 

$academicDate = $_POST['aDate']; 
$academicDescription = $_POST['aDescription']; 
$academicTitle = $_POST['aTitle']; 

$sql = "INSERT INTO academicnews (id, newsDate, newsDescription, newsTitle) VALUES ('', $academicDate, $academicDescription, $academicTitle)"; 

if (mysql_query($sql)) { 

echo "Record Aded to Database. Hit OK to add more"; 

}else{ 
    echo "Failed to add record to database"; 
} 

?> 

注意标识符是AUTO_INCREMENT号.....和config.php文件代码..

<?php 
########## MySql details (Replace with yours) ############# 
$username = "root"; //mysql username 
$password = "s1j55b123456789"; //mysql password 
$hostname = "localhost"; //hostname 
$databasename = 'dominie'; //databasename 

$connecDB = mysql_connect($hostname, $username, $password)or die('could not connect to database'); 
mysql_select_db($databasename,$connecDB) or die(mysql_error()); 

?> 

我如何解决这个问题（它回声无法添加记录）问题...任何帮助，将不胜感激..感谢前进...... :)

Answer 1

试试吧，请：

$sql = "INSERT INTO academicnews (newsDate, newsDescription, newsTitle) VALUES ('$academicDate', '$academicDescription', '$academicTitle')"; 

Answer 2

我什么e是当你的值不是数字值时，你不使用引号。

尝试：

$sql = "INSERT INTO academicnews (id, newsDate, newsDescription, newsTitle) VALUES ('%', '$academicDate', '$academicDescription', '$academicTitle')"; 

Answer 3

试试这个

$sql = "INSERT INTO academicnews (newsDate, newsDescription, newsTitle) VALUES ($academicDate, $academicDescription, $academicTitle)" ;
