所以我试着用这个2-3，但我没能成功。我有这个主题：Aruna和他有前端帖子，当我发布图片时，我需要写标题并从我的电脑上传图片，你可以在图片上看到：
好的，在我完成这项工作后，他将我上传的图像按主题放入一个自定义字段：
诀窍是，当我想从前端上传图像时，我想将其自动放在特色图像上。如果我使用用户提交的帖子插件，并且我从他那里发帖，那么它会起作用。。但我想在自己的前端进行修改。这对我来说很重要，因为我在facebook和其他社交媒体上分享了很多信息，功能图片可以做到这一点：）我不知道在这里放什么代码，但我试着向你展示：功能。php

前端HTML代码

<input type="file" name="image_imagepost" />
<input type="file" name="image_imagepost" /> this do the trick for upload on custom field ...
