How to hook into "view" links on tree and page edit

[steveooo]

Ahoy captain!

I need to hook into 2 areas of ProcessWire:

- "view" page link on page tree

- "view" page link on page edit

(Are there more areas with these "view" links for pages or did I get everyone?)

How can I hook into that in order to change the "view" link url?

Arrr! It would be great if someone would help me with that!

Are you just wanting to add a _blank target? If so, then the easiest option might be this:

https://processwire.com/talk/topic/7588-admin-custom-files/?p=89331

which of course uses Martijn's AdminCustomFiles.

Here's where the link and it's url is defined: https://github.com/ryancramerdesign/ProcessWire/blob/master/wire/modules/Process/ProcessPageList/ProcessPageListActions.php#L38-L93

Hi. No, I want to change the url to something different.

@LostKobrakai: This is only for the "view" link on the page tree actions, right?

How can I hook into the "view" link when I edit a page.

Any examples? I am not that great in "hooking"

A module is needed doing this.

Get informed about hooks here: https://processwire.com/api/hooks/

This one should do the job
