Question

我是PHP的新手，我有兴趣在这些表中插入值之后立即从名为sub_credits的链接表（插入submit_id和credits_id）中的两个表中添加主键ID作为外键。任何帮助都会很棒！这是我的代码：

                    //write the data to the database
                    $query1 = "INSERT INTO submissions (user_id, date, " . 
                             "submission_type, title, zipfile, " . 
                             "copyright, review)" . 
                             "VALUES ('" . $_SESSION['user_id']. "', NOW(), " . 
                             "'$submission_type', '$title', " . 
                             "'$zipfile', '$copyright', '$review' )";
                    $query2 = "INSERT INTO credits (credits) VALUES ('$credits')";
                    mysqli_query($dbc, $query1)
                            or die ('Data not inserted.');
                    mysqli_query($dbc, $query2)
                            or die ('Data not inserted.');

您可以使用 mysql_insert_id();

获取ID

$query1 = "INSERT INTO submissions (user_id, date, " . 
                         "submission_type, title, zipfile, " . 
                         "copyright, review)" . 
                         "VALUES ('" . $_SESSION['user_id']. "', NOW(), " . 
                         "'$submission_type', '$title', " . 
                         "'$zipfile', '$copyright', '$review' )";
mysqli_query($dbc, $query1) or die ('Data not inserted.');
$id1 = mysql_insert_id();

$query2 = "INSERT INTO credits (credits) VALUES ('$credits')";

mysqli_query($dbc, $query2) or die ('Data not inserted.');
$id2 = mysql_insert_id();

您可以使用$id1＆amp; $id2使用新的插入查询插入新表。

$query3 = "INSERT INTO new_table(submissions_id,credits_id) VALUES ('$id1','$id2')";
mysqli_query($dbc, $query3) or die ('Data not inserted.');

其中submissions_id,credits_id是新表的外键

PHP将值插入到两个表中，并将这些表中的键插入到链接表中
