Please add info for admins regarding Google analytics
{syntax type="tiki" editor="plain"}
Tiki has the option to interact with Google Analytics.

Now the first court rulings are there: Google Analytics directly violate the GDPR, therefore they are illegal throughout the EU. Fines are VERY heavy, so this must not be taken lightly. The fines range up to 20 million Euro or 4 percent of a year's turnover (sic! Not profit!), whichever is HIGHER.

Yes, Analytics is optional, and it's the decision of an admin, correct.

But IMHO Tiki should inform the admin when he/she activates this, that compliance with current law must be observed, and that Analytics can be (very) problematic in this regard. And to be on the very safe side, IMHO there should be a checkbox that spells out as confirmation "Yes, I am aware of the compliance issues imposed by this".

Please Note: Dogfood notice Enough already please
Noob here enjoying the site, enjoying the software and finding my way around. Thank you.

It means spending a *lot* of time at the Tiki sites.

I get the message already about the dogfood. Cool.

But every day, every page load, I must dismiss this notice to uncover what is underneath. Or scroll the viewport out from under it.

It is located on top of the navigation.

Can we not have it fixed in the page above the navigation, or permanently dismissable once logged in, or ...?

Can we just use the site now, and stop swatting at the javascript? :)

I'm just setting up svn etc now. And wouldn't have the balls to make such a visible change right off the hop anyway. It's not real important obviously. But if somebody is there and knows and can do, it would make surfing the sites more pleasant...

Cheers!!

Please rename the start button in the wizards
{syntax type="tiki" editor="plain"}
Please rename the start button of the wizards.

The reason is that the translation function tra() is completely ignorant of context. And at least in German the problem arises that the imperative of starting, that "start" means, is different from the noun that marks the beginning of a calendar event. In English both are "start", but not in German.

In German that is "Beginn" (as with all nouns with upper case 'b'), while the imperative of starting would be "beginne" (as with all verbs with lower case 'b'), or in the preferred more professional looking passive construction "beginnen". The verb "starten" also exists, with that it would either be "starten" or "starte", but this arises the problem that if I rename one, I must as a consequence also rename the other. It is not possible to correctly translate both!

Because tra() is igorant of context... So I have to make a decision which wrong translation does lesser damage... So please find a different string for "Start". Preferrably, since it might take aeons before tra() becomes context sensitive, one that carries the context inside the string itself, like "start wizard". This should be a recommendation FOR ALL STRINGS throughout Tiki...

Plugin Add to Cart to use existing data from tracker item
Plugin Add to Cart is used in conjunction with a tracker item (the product).

Plugin List and ListExecute displays code when field is a tracker item title (link)
Once a tracker field is set as title, it turns to be a link to the tracker item.

In certain (but several) condition when using a plugin List, ListExecute or the plugin Map this field(link) will be inserted into another link and then the display will be broken and it will show code instead of item link. (a link within a link is bad)
Check the instance.

First problem: There is nothing that can tells you from where come the issue and only after several experience and Jonny’s help we found out what it was. Anyone else (and new comers) won't have any idea why the display is broken.

Second problem: __It is a pain !__

Workaround are messy; you have to duplicate fields (Name and Title), title has to be set to a different field (like Id) and start confusion or worst, previous setting that were ok turn to be broken.

Would it be possible to have some kind of strip there ?
(if the value is already a link, strip <a ...). There is a smarty function for that "Strip" couldn't it be easily set ?

Plugin ListExecute with email sending garbage if tracker field type is file
It is not possible to use the plugin ListExecute to send an email that contain a tracker field type file. If you do so it will send different kind of un-useable code.

There is a debate about inserting a file in an email and maybe this will be fixed/changed one day. In the meantime it will be cleaner to display proper error or warning something like "it is not possible..."

Plugin TrackerStat: allow showing the description of tracker fields in the display of results.
Plugin TrackerStat has no easy replacement with Plugin List, as far as a I know.

When trackers are used to fill in questionaires, there are sometimes long phrases that are written in full in the description of the field, and the field name is just some short name to refer to it.

When the user fills in the form, the field descriptions can be shown below the field.

But when results are shown through PluginTrackerStat, no field description is shown, and in some cases, it's hard to understand the answers without the full text shown in the description of the field.

This could be solved with a param to optionally display the field descriptions in the Plugin TrackerStat.

Plugin TrackerStat: natural case sorting on the answers (text strings)
Plugin TrackerStat has no easy replacement with Plugin List, as far as a I know.

We need to have the answers to a question (tracker field) sorted with natural case sorting. For instance, if you ask in the question a radio button showing options from 1 to 24, you will get the answers sorted as something like (copied from a production site):

{CODE(ln="1")}
1 10 %3.12 <->
1 11 %3.12 <->
2 12 %6.25 <->
1 13 %3.12 <->

Plugins broken in Blog inn 1.9.2
When putting a plugin onto a blog post which requires parameters, the parameters are not passed in or are passed in as an &. This happens when the => syntax is used, or quotes are used around the parameter. These are otherwise fine when in a wiki page.

Most plugins appear to be affected on my installation - which was an upgrade from 1.8.4 to 1.9.2.

They render okay when viewing individual posts, or previewing, which leads me to beleive it is in tiki-blog_view.php somewhere.

After diffing the files, the largest visible change was the addition of categories into the blog, this is however not affected by turning off the feature in admin.

I am putting this high on my own priority list as I cannot upgrade my live site to 1.9.2 (although it has had some secuirty fixes put on it) until this is solved as I do not want to break my history of blog posts using plugins.

Perhaps it is worth a shot on this site or tikiwiki.org to see if plugins are affected here as well with that.

Possible bug at creating base Tiki DB tables
The basic Tiki DB initalization IMHO contains an error. Maybe this is due to a change introduced later that made the INSERT incompatible to the CREATE. /db/tiki.sql contains this at lines 2867-2878:
{CODE(Colors="Tiki")}
DROP TABLE IF EXISTS `users_usergroups`;
CREATE TABLE `users_usergroups` (
`userId` int(8) NOT NULL default '0',
`groupName` varchar(255) NOT NULL default '',
`created` int(14) default NULL,
`expire` int(14) default NULL,
PRIMARY KEY (`userId`,`groupName`(225))
) ENGINE=MyISAM;

INSERT INTO users_groups (`groupName`,`groupDesc`) VALUES ('Anonymous','Public users not logged');
INSERT INTO users_groups (`groupName`,`groupDesc`) VALUES ('Registered','Users logged into the system');
INSERT INTO users_groups (`groupName`,`groupDesc`) VALUES ('Admins','Administrator and accounts managers.');

This should not work. Maybe the resulting error is just ignored? Values are entered into the non-existent column "groupDesc"...

Possibly wrong help text for facets
(or, alternatively, wrong user input method) The admin UI for the facet feature describes, that the user shall enter a comma-separated list of categories, yet a multiselection window is presented.

Interestingly, in /lib/prefs/category, where this help string comes from, is text input specified ?! If that would be presented, the text would be right, but somehow it is not...

{CODE(Colors="Tiki")}
'category_custom_facets' => [
'name' => tr('Generate custom facets from categories'),
'description' => tr('Comma-separated list of category IDs.'),
'type' => 'text',

Profile 'Dynamic items list' doesn't load in the admin panel & error shown through 'profile tester'
After an issue reported by a user in dev.t.o, and an example produced in the corresponding show.t.o site, I decided to create the corresponding profile to be able to test dynamic items list easily from now onwards in different tiki versions, etc. That's the rationale of this profile:
https://profiles.tiki.org/Dynamic+items+list

After I added the sections with data ("Objects in Products Tracker" and "Objects in Service Tracker"), the profile doesn't load any more in the Tiki admin panel for profiles.

And when I added that yaml code in tiki-admin.php?page=profiles&cookietab=3 > "Profile Tester", then I got this error message:

{CODE()}

Any tips?

When you edit a banning rule, that rule gets deleted (at least, from the list at the Banning interface in Tiki).

To reproduce:
* go to tiki-admin_banning.php
* add a rule for this ip "91.201.66.6" (real ip of spammers, btw) with the title "91.201.66.6_regular_spammers"
* Check all features
* Check the setting to activate the rule by dates
* Select the maximum possible time frame (btyw, this only allows selecting within the same year: reported by somebody else already in another bug report; see [bug3643])
* add some custom message
* save
* click at the title of your rule in order to have it open for edition again for you
* the rule is deleted from the list of rules, and the edit interface is empty

15.x: Improvements needed for mobile view of many *.t.o sites (dev, themes, doc, ...)

(1) No way to login at dev.t.o or doc.t.o, for instance, when browsing the page in the smartphone
(tested with Chrome on Android, but it seems to be reproduced with a browser on a desktop and making it narrow enough as a smartphone)

(2) There is no logo nor site name displayed in the top header of most *.t.o sites. OTher (non-tiki) bootstrap websites do display their logo and name when shown through smartphone. IS tehre anything that can be done in the Tiki side to fix this?

(3) Fullscreen button is shown on top of the button at the top layer to display the logo and site name. Therefore, clicking there, fires the fullscreen in some cases. And when in full screen, in a smartphone, I couldn't come back to normal display mode clicking at that button in the smartphone for some reason, I had to fix the param in the url to get back to normal.

(4) The submenu is not shown in dev.t.o and doc.t.o but it is shown in themes.t.o Why? How shall we edit the submenus so that they are shown in the smartphone display?
