typecho博客主题美化总结篇—php单文件相册管理

看过我前面两期博客的都知道,最近lz在专心建设自己的博客。因为是基于typecho,用的朴素简洁的博客主题,就注定了各个模块都需要自己亲力亲为的去设计,开发。不过这种经由自己手从无到有,从朴素空白到唯美充实的过程确实也很值得期待。

1.前言总结

流情的博客总共涉及了相册,微语,留言等几大独立模块页面。至于归档,友链,关于改动并不大。归档主题自带的,友链用的插件,关于引入的正是lz之前博客说的轻量js聊天框架botui.

轻量型js聊天框架Botui(附示例源码)-CSDN博客

留言板块引入的是lz上次说的拖拽式便签留言。

微语其实就是一个阉割版的将留言当做发说说进行展示,这个模块不多加叙述。

最后,说到的就是相册,相册是一个比较麻烦且耗时最长的一个模块。经常搭博客的应该都知道,主题自带相册的不能说没有,只能说很少,要么就是纯粹的相册主题博客。而且还涉及到多个相册,相册加密,图片附带文字描述,图片预览,图片懒加载等等这些一系列的或不可缺的东西,如此看来,你觉得相册还简单吗?

2.效果展示

在线地址: 流情的博客

博客框架:typecho

博客主题:jasmine

流情的博客从主题,博客框架选定,到搭建,美化,模块开发和调试,到现在差不多可以告一段落了。先来看下效果。

3.相册模块

相册目前可以实现多相册,相册加密,懒加载,图片预览。瑕疵肯定还是有的。因为图片的上传和相册图片展示还涉及到半手动,并不能达到全部后台控制。关于相册的一些前期说明,可以参考lz博客里的这篇文章:typecho自定义相册模块 - 流情的博客

因为都是二次开发或者引用插件调试出来的,因此也没法提供独立的插件或者全部的说明,毕竟这个相册是针对这个主题打造的,有一定针对性,lz只能简要说下思路以及关键代码。

3.1 相册展示效果

首先是做出相册的展示效果,这里是基于light这个主题来的,通过html+js+css打造出来类似的图片展示效果。然后创建对应的模板页面。总所周知,博客的模板页面,除了一些导航侧边啥的,有一个核心的div内容,里面就是你自定义要展示的东西。

所以,只要提取出效果的html页面,要引入进去就不难了。

3.2 动态相册

lz针对相册效果一共创建了两个模板页面,一个展示相册,一个是展示相册图片。相册一般改动不多,但是相册的图片是动态,所以这里投机取巧了一下,一个相册对应一个独立页面,并应用相册图片的模板页面,让相册图片以富文本的方式插入来实现动态的展示相册图片效果。

3.3 相册图片管理

这么说一般人可能看不懂,毕竟是针对typecho有一定了解的人而言,lz也是捣鼓了一段时间才搞清楚的,独立页面和模板页面,插件等等这些的关联。不懂就不懂吧,下面这段代码功能是自动扫面目录列表及目录下的图片,并实现对图片的上传和删除。这里是用来做相册图片的管理插件的,但是用做普通的目录图片管理也行。

4.小结

人生的意义就在于不断的折腾,本来就是看重这个主题很简洁才选中的,结果在美化的道路上一骑绝尘,不断的丰富和加模块,加单页。好在现在还符合预期。但是人的欲望又是无穷尽的,lz又想搞事情了,弄个实验室页面,展示一些自己的self-host如何?
