推荐答案
存在多个问题.其中一些:
There are multiple problems. Some of them:
- 您的查询字符串有误.你有
VALUE而不是VALUES - 您将查询字符串分配给
$query执行后 - 停止使用已弃用的
mysql_*扩展并切换到 <代码>mysqli_* 或PDO - 验证和清理用户输入
- 学习和使用准备好的语句而不是插入查询字符串.后者是 sql 注入的大门.
- Your query string is wrong. You have
VALUEinstead ofVALUES - You assign a query string to
$queryafter you execute it - Stop using deprecated
mysql_*extension and switch to eithermysqli_*orPDO - Validate and sanitize user input
- Learn and use prepared statements instead of interpolating query strings. The latter is a wide open door to sql injections.
现在回到你眼前的问题.尝试改变这部分
Now back to your immediate problem. Try to change this part
if($query_run = mysql_query($query)){
$query="insert into mylibrary value('$isbn','$title')";
mysql_query($query);
echo "Successfully store in DATABASE";
}
像这样
$query = "INSERT INTO mylibrary (isbn, title) VALUES('$isbn', '$title')";
$result = mysql_query($query);
if($result) {
echo "Successfully stored in DATABASE";
} else {
echo "Something went wrong: " . mysql_error();
}
