How to manipulate final output?

Question

Hi, I need to manipulate the final output before it goes out to browser.  I manage to hack the core to do it, but is there a plugin/more elegant way to do this.

Side note: I am doing this for adsense plugin.  I found that the plugin loads before the logic of the page is fully executed.  So based on page's logic, I need to turn adsense blocks on/off.

Comments

alternatively, how do "late execute" a plugin - i.e. after the page has completed its full logic.

@Leo, adsense used to hand out medals. Now they only ban you :)

What exactly do you need to do?

hi @pupi1985, I need to get control of the output stream. So I can turn adsense blocks on/off depending on certain conditions (e.g. don't show adsense on user banned page).

I already got it working using 'shutdown', please see my answer.  For adsense, I could also hook it to shutdown which is a much more elegant solution.

@Leo, let's say a person has a very bad name.  The user page still shows (at least I believe..).  So I had to post-process it.

Answer 1

I think I figured it out actually, and thanks to @Leo for hints.   The way to do it is to use the shutdown($reason) process module http://www.question2answer.org/modules.php?module=process and use ob_start to manipulate the output stream.  I am not good with writing plugins yet, but that is the correct direction, I believe.

I want to check just in case. Is your "adsense plugin" "qa-plugin/basic-adsense" in Q2A?

yes, basic-adsense

Do you know "Widget Anywhere"?

Feature is different, but this plugin has know-how related to widget control. This plugin is simple. However, very powerful. Analysis will not be difficult.

Thanks, @sama55.  Interesting plugin.  I will check it out.
