I have an accounts table containing the account username and password and a separate contacts table which is liked to the accounts table by the username. 我有一个包含帐户用户名和密码的帐户表,以及一个单独的联系人表,用户名对帐户表很喜欢。 I need to insert in to both of these.
我需要插入这两个。 here is what I have so far.
这是我到目前为止所拥有的。
Thanks 谢谢

...and I think your problem will disappear. ...而且我认为您的问题将消失。
It would be worth you re-reading this and this . 值得您重新阅读本和本本 。
Note also that you should be using the POST/Redirect/GET design pattern for handling form submissions of this nature. 还要注意,您应该使用POST / Redirect / GET设计模式来处理这种性质的表单提交。
This code block doesn't do what you think it does 此代码块无法完成您认为的工作
What this does is sends query sql1 and then if that query failed does sql2. 这样做是发送查询sql1,然后如果该查询失败,则发送sql2。
$result = mysql_query($sql);
if(!$result)
$result = mysql_query($sql2);
if(!$result)
If you want to insert into both of them then you should do 如果您想同时插入两者,则应该
$result = mysql_query($sql);
if(!$result) {
echo "first query failed";
}
else { $result = mysql_query($sql2); }
if(!$result) {
echo "second query failed";
}
