如何在MODx Revo主页上添加帖子缩略图？

Question

I'm new to MODx. Adding in the post thumbnail creates a visual association for each post or page. How to add post thumbnail on homepage? How to show first image in the post as thumbnail on home page?

As a to WordPress:

Answer 1

If you are trying to use modx as a blogging platform you should look int installing Articles, Archivist & phpthumbof - these packages will provide all the tools & snippets you need to get that done. [If not Vasis's solution will be far easier]

Answer 2

Here are two solutions

1. Create image tv, and manually set image every time when creating a resource.

2. Create an input filter and apply it to the content field -

snippet get_first_image :

<?php
preg_match('/<img[^<>]+src=[\'"](?P<src>.+)[\'"][^<>]*>/i', $input, $image);
return $image['src'];

and to get image in main page template:

<img src="[[+content:get_first_image]]">
