向所有人致意,尤其是向CodeIgniter开发人员的高级人员致敬。
我对使用CodeIgniter构建的网站有问题(我不是以前的雇主所继承的开发人员 )。该网站无法正常工作,尤其是在上传图片并显示有关
的警告时错误号:1048'article_image'列不能为空
我确实尝试在脚本和数据库上找到问题,但是没有任何变化,因为没有人更改代码和内容。今天,我再次尝试将“ Null变成yes”(以前是“ No”),并尝试上传文章。它正在运行是一个奇迹,但是下一个问题是图像消失了(损坏)。我在寻找其他与我有相同问题的人时说,我需要升级CodeIgniter。我的是3.0.0,而最新的是3.1.10。我将内容复制粘贴到/ System和/ views / error / cli内,虽然效果不佳,但更糟的是,网页上的图像不见了(丢失)。
这是我的Article_model

我应该怎么做?我做了备份,但升级后仍然一样。谢谢。网络网址(http://www.hidupseimbangku.com/)
答案 0 :(得分:0)
首先。如果要升级CI版本,则必须一一遵循升级指南。可能会有中断更改,您需要更正它们,您可以在这里找到本指南:
https://www.codeigniter.com/userguide3/installation/upgrading.html
我建议您回滚升级更改,然后再次开始一个接一个地做。这并不难,只是在浪费时间。
您收到的错误可能与上载过程中的错误有关。什么是file_upload
?
我还建议您阅读this,以正确上传文件。
