How to make a post open a specific link

In my wordpress blog, I want to make a specific post open a specific link, that is when someone clicks on this post, I don't want the post to open, instead I want to redirect the visitor to a new link that I already know.

Ca开发者_开发技巧n you please tell me how to do it ?

In other words you want to use one posts teaserview as a teaser for another post... I would recommend not doing it that way even though it is possible. I would rather write a different text in the Excerpt.

"The WordPress Excerpt is an optional summary or description of a post; in short, a post summary.

"The Excerpt has two main uses:

1. It replaces the full content in RSS feeds when the option to display summaries is selected in Dashboard › Settings › Reading.

   Depending on the WordPress theme, it can be displayed in places where quick summaries are preferable to full content: Search results Tag archives Category archives Monthly archives Author archives "

To also show a different image when in teasermode I would use Custom Fields:
