Thanks, Rob.

Does that answer your question or have I misunderstood?

Hm, I am not sure. I have a category, in which I have some pages that have tags, and some that don't. The pages that have tags, they do not have all the same tag, but many different tags. I want to list ALL of those pages, no matter the tag they have. For example, let's say I have 100 pages of a category, in which, 40 don't have tags, and 60 have many different tags. I want to list those 60 pages. Those 60 pages have many different tags that may or may not coincide, some have only one, ans some have up to three or four tags… Therefore, I cannot have "tag=the name of the tag". I was thinking that maybe there is some sign, as there is for "pages with no tags" (which is "-") that will list "pages with tags", i.e. pages with ANY visible tag.

On the other hand, I don't understand the purpose of + in front of a "google" word. I mean, if you want to list all the pages that have tag "google", you can do it without putting + in front… (Maybe I am missing something here, I don't know…)

Yes, the + is optional when you are only asking for one tag. But, look at these three examples:

Does that make sense? :)

• + means that the tag must be on the page for it to appear in ListPages results
• — means that the tag must not be on the page for it to appear in ListPages results
• If you don't have any "+" or "-", then as long as one of the tags you've written is on the page, it will appear in the results and the other tags will be ignored.

Ah, ok. Thanks, Shane. Now I understand.

As far as my first question, I suppose there is no sign that would list only the pages that have ANY tag…? It does not matter which tag, as long as the page has it… I hope you understand me… :(

Yes, I understand what you want to do. I don't think it's possible :|

I'm thinking that I should add it to the design for ListPages improvements here: http://projects.wikidot.com/thread:120, but am not sure what symbol to use to represent "something", i.e. "has a tag, but we don't know what it is".

Perhaps tags="+" could mean pages with any tag, visible or invisible? I'll use that…

Tags selector:

• "-" means pages with no tags, visible or invisible
• "=" means pages with any of the same visible tags as this page
• "==" means pages with the exact same visible tags as this page
• else, a list of space/comma delimited tags
• tags are by default additive (tag OR tag OR tag)
• "-tag" means pages without the tag (AND NOT)
• "+tag" means pages with the tag (AND)

"+" will be fine. Could we expect this improvement soon? I really need it…

I have no idea…

…though as it's probably a simple thing to do, chances are it will be added relatively soon as opposed to some of the other feature requests.

OK, thanks for the quick answer.

Perhaps tags="+" could mean pages with any tag, visible or invisible? I'll use that…

While I can't think of a real use case at the moment, to me it would make sense that the + and - options were somehow set up to handle all combinations:

pages with no visible tags
pages with no invisible tags
pages with no tags, visible or invisible
pages with any visible tags
pages with any invisible tags
pages with any tags, visible or invisible

And similar possibilities for the = parameter:

pages with any of the same invisible tags as this page
pages with exactly the same invisible tags as this page
pages with any of the same tags as this page, visible or invisible
pages with exactly the same tags as this page, visible or invisible
(you've already got visible tags covered)

I don't have a clue what the best way to indicate that would be.
And then, would/could we allow something like tags="+-" meaning pages with invisible tags only. My head is starting to spin thinking about this. Time to leave it alone… :D

Hahaha, yeah, that's a lot of combinations ;-)
Perhaps just adding them as they are needed will be good enough.

Don't you mean tags="+_" not tags="+-" ? :P

You were also confused :-P ha ha

Well, yes… :) Maybe I should explain why I need this:

I need this because I have just installed the random picture in my sidebar which shows pictures that are uploaded at the site. Since I am still uploading the pictures (each picture has its own page which all belong to the same category), all pages with already uploaded picture have tags, and those that don't have uploaded picture, don't have any tag. Therefore, if I want this module to work already and to show all the pictures that I have uploaded so far (I have some 140 uploaded but some 200 more that are still waiting to be uploaded), I need the parameter that determines "all the pages with the tag", since all the pages that have tag, also have uploaded picture.

Uh, I hope I explained it well…

But I made a list of all the pages, just showing their linked title, so that if you click on it you go straight to the page, and their tags….

So you could easely see wich page had tags and wich did not.

[[module ListPages category="howto" separate="no"]]
||%%title_linked%%||%%tags%% %%_tags%%||
[[/module]]

Have a look at this list

No, you did not understand me. I don't need to know what pages don't have tags¹. I need them to be skipped in my random picture module, since they don't have uploaded picture and therefore, the picture will not show. Here's my code:

[[module ListPages category="slika" tag="историја_уметности" order="random" limit="1" separate="no"]]
[[=image http://istorijska-biblioteka.wikidot.com/local--files/%%full_page_name%%/%%name%%.jpg link="http://istorijska-biblioteka.wikidot.com/%%full_page_name%%" width="120px"]]
[[/module]]

Therefore, I had to limit myself to the pictures with a tag историја_уметности, but there are a lot more pictures that have other tags, and I would like them to be shown in a random picture module as well. Another option is to put all the tags I put so far to all pages in a category "slika", but I think this is too boring job so I'll pass it…² I need this "page with any tag" parameter, because I still have 200 pictures to upload, so I don't think it will be very soon, so I can exclude tag parameter completely…

The code gives the random picture in the top of the side bar…

I came across somebody who wanted to do something with pictures… and somebody said something on the forum… use first picture or first file… That would do the trick I think… no hassle with tags… Of course I don't find the thread where it is discussed

This rings the bell to me to… I recall of something like that… But of course, I have no idea where I should look for it… :(

Is it something like that the module picks the first picture attached to the page, and if there is no picture, it does not show?

If there is no image, I'm pretty sure it just shows the type of thing that means "no image found at that URL" … which is different for each browser. A small red "X", for example.

Would need to test it though… as I'm not sure on that one.

I'm pretty sure it just shows the type of thing that means "no image found at that URL"

This is precisely what I want to avoid…

Actually, I wonder if there is a way to specify the image that will be shown when no others are found, using CSS… Rob, Ed, James, or any other CSS guru around here — can you provide some input on this? :)

Not directly as you can't have conditional statements in CSS (although there are javascript workarounds). Perhaps what you could do is to use one of the header-extra-divs to show a default picture in exactly the same place as the "real" image. Some clever work with z-indexes might then put the correct image in front of the default one. I haven't tried it but it might work.

In that case, the "no image found at that URL" icon would still appear over the top of the default picture, correct?

Normally if you just use the [[image..]] tag to dispolay an image and it isn't there, it just displays the name of the file. This can easily be hidden by setting the color property in the .img class to the background color, white for example. However, If it's a wikidot generated error you might be able to put this in your CSS to suppress the error message:

.error-block {
    display:none;
}

But this will have knock-on effects with other error messages.

Sorry I just can't see a way of doing what Brunni wants other than adding a specific "photo" tag to the pages that have been created already.

That's where we need bulk tagging of pages.

Oh wow. The answer has been there all along and I only just thought of it? :(

Brunhilda, this should show nothing at all if no image was found… :P

Well done, there's so often a simple solution that we never think of until the complicated answers are exhausted.

[[image :first]]

should do the trick

The image is being accessed from a different page to the one it is attached to, so that will not work.
