php检索插入的最后一条记录的id并将其插入到另一个表中

我正在尝试检索插入到“authors”表中的最后一条记录的 id，并将检索到的 id 插入到“articles”表中；这是我的代码：

$title = mysql_real_escape_string($_POST[title]);
$body = mysql_real_escape_string($_POST[body]);
$category = mysql_real_escape_string($_POST[category]);

$insert_author="INSERT INTO authors (name) VALUES ('$title')";
$select_author= mysql_query("SELECT LAST_INSERT_ID()");

$authId = mysql_fetch_array($select_author);
$query="INSERT INTO articles (body, date, category, auth_id) VALUES ('$body', '$date_now', '$category', '$authId')";

这不起作用...

有什么想法吗？

预先感谢

I'm trying to retrieve the id of the last record inserted in the table 'authors' and insert the retrieved id in the 'articles' table; here's my code:

$title = mysql_real_escape_string($_POST[title]);
$body = mysql_real_escape_string($_POST[body]);
$category = mysql_real_escape_string($_POST[category]);

$insert_author="INSERT INTO authors (name) VALUES ('$title')";
$select_author= mysql_query("SELECT LAST_INSERT_ID()");

$authId = mysql_fetch_array($select_author);
$query="INSERT INTO articles (body, date, category, auth_id) VALUES ('$body', '$date_now', '$category', '$authId')";

this doesn't work...

Any idea please?

Thanks in Advance

您可以使用 mysql_insert_id( )

$insert_author="INSERT INTO authors (name) VALUES ('$title')";
mysql_query($insert_author) or die(mysql_error());

$authId = mysql_insert_id();

$query="INSERT INTO articles (body, date, category, auth_id) VALUES
('$body', '$date_now', '$category', '$authId')";

注意，您缺少用于插入查询的 mysql_query 函数，我也在上面的代码中添加了该函数。

You can get the last insert id with mysql_insert_id()

$insert_author="INSERT INTO authors (name) VALUES ('$title')";
mysql_query($insert_author) or die(mysql_error());

$authId = mysql_insert_id();

$query="INSERT INTO articles (body, date, category, auth_id) VALUES
('$body', '$date_now', '$category', '$authId')";

Note that you were missing mysql_query function for insert query, i have added that also in code above.
