我有2个数据库，一个是backup_list和磁带。 backup_id是backup_list的PK和磁带的FK。如何将数据从一个查询插入到两个表中。有tapecode，备注，验证的动态文本字段。请帮我。
<script type="text/javascript">
var i = 0;
$(document).ready(function() {
$('.addNewTape').on( "click", function() {
$(this).parent().siblings(".Tape_Code").append('<input type="text" name="inputTapeCode[1]['+ i +']" value="'+ i +'" /><br>');
$(this).parent().siblings(".Operator_Verify_Status").append('<SELECT name="Operator_Verify_Status"><OPTION value="verify">Verify</OPTION><OPTION value="NotVerify">Not Verify</OPTION><OPTION value="Failed">Failed</OPTION></SELECT><br>');
$(this).parent().siblings(".Operator_Remark").append('<input type="text" name="inputTapeRemark[1]['+ i +']" value="" /><br>');
i++;
});
});
</script>

答案 0 :(得分：0)
使用LAST_INSERT_ID()获取您在插入backup_id时分配的backup_list。
if(mysqli_query($MySQLiconn , "INSERT INTO backup_list(Backup_Name, No_Of_Backup) VALUES('" . $Backup_Name . "', '" . $No_Of_Backup . "')")) {
mysqli_query($MySQLiconn, "INSERT INTO tapes(backup_id, Tape_Code, Operator_Verify_Status, Operator_Remark)
VALUES (LAST_INSERT_ID(), '$Tape_Code', '$Operator_Verify_Status', '$Operator_Remark')";
$successmsg = "Successfully registered";
}
顺便说一下，您应该了解准备好的查询，而不是使用mysqli_real_escape_string和变量替换到查询中。见How can I prevent SQL injection in PHP?
