Allow to control permissions for index/dashboard widgets

It is possible.

In the php file of that particular widget (in controller/components folder)

Check

if(OW::getUser()->isAuthenticated()){
  return;
}

I have three custom text/HTML on my index page and I want to make visible the three widgets for guests and visible only two widgets for logged in users. I found "return self::ACCESS_ALL;" in /ow_system_plugins/base/components/custom_html_widget.php line 96, but this permission affects to all the widgets, so I want to know if there is a way to keep the widgets visibles and non visibles.

You can use this as you want.. using "return" will make the widget invisible.

What i am actually trying to do is to make an image [its my JOIN button] on the index page in the sidebar disappear when users signed in. Image code is in a 'custom html box' - Is this possible?

Purus: I did not know where to put the code. I put it in differents places into the file /ow_system_plugins/base/components/custom_html_widget.php without success.

Richard: That's exactly that I want. If you are using only one widget of the kind "custom text/HTML" you just need edit the file /ow_system_plugins/base/components/custom_html_widget.php and change line 96 to return self::ACCESS_GUEST. I repeat, this will work only if you have one widget, because if you have more widgets of the same kind, will be invisibles too (that's my case).

Richard: This is not elegant but you can put the code inside the join widget, instead the text put <img src="image" />.

You should put that in the widget file that you want.

For example if you want this done for the groups widget..
ow_plugins/group/component is the place

Thanks Purus for your support, but I think I'll wait for the next update :(

I tried this pablo - it worked but i cant change it back now for some reason or alter it at all, any ideas... I tried going into languages but when i try to save changes it leads me to 'Page not found'

Richard: You can go to language file in ../ow_pluginfiles/base/lang_x.php and edit it.

hii puru do you have idea about this matter!

in news feed '"puru joined our site" i want to make it puru joined(sitename)
how to do that??

edit the language string.. add {$site_name} to the string.

Solved with 1.5.2
