前言

在评论时,我们往往需要附上图片以更明确地表达自己的想法,Typecho中虽然没有原生的评论区图片上传功能,但是也可以通过HTML的img标签在评论中附加图片。不过,这其中有一个大麻烦:图片需要上传到图床,才能获得图片链接,进而插入img标签。这是一个很麻烦的过程,也正因为如此,除非迫不得已,没有人愿意选择在评论中添加图片。
现在,我们就来解决这个问题。先附上效果图,如下,你也可以在下方的评论区中验证效果。([font color="#FFFF00"]注意:部分图床会被qq、微信内置浏览器拦截,想要获得完整的演示,请在系统浏览器中打开网页。[/font])

效果图

之前写了一篇文章,关于怎么在评论区将图片上传到图床实现图片评论,并且不占用服务器空间。

文章是在对功能实现的方法一步步摸索中逐渐构建出来的,现在看起来真是杂乱不堪。

总的来说,现在功能已经能够实现了,也能很好的支持PJAX加载,就以此篇文章,为这个项目划上句号吧。

实现图片评论

此方案不兼容手机应用内置的浏览器,如QQ、微信等自带的浏览器。因为实现上传操作需要同时打开两个窗口,而内置浏览器往往没有多窗口支持。

放行HTML标签和属性

后台-设置-评论-允许使用的HTML标签和属性中添加下列内容,并保存,否则会评论失败。

<img src="">

修改handsome源码以适配chevereto

文件路径:/usr/themes/handsome/libs/Content.php第2324行

echo '<textarea id="handsome_md_text" class="hide" >' . htmlspecialchars($content) . '</textarea>';

修改为

echo '<div id="handsome_md_text" class="hide" >' . htmlspecialchars($content) . '</div>';

添加自定义js代码

主题后台-开发者设置-自定义 JavaScript中加入下列代码:

chevereto();
function chevereto(){
(function() {
    for (var t = {
            defaultSettings: {
                    url: "https://pic.6zs.cn/upload",
