Dumb Question? How to combine Tags?

[Juri]

Is there a default way to select a combination of tags so that only the tiddlers with said combination are shown? Or how can I get a list with Checkboxes to do this?

Right now all I have is this:

<$list filter="[tag[ExampleA]tag[ExampleB]sort[title]]">

<<currentTiddler>>

{{||$:/core/ui/ViewTemplate/tags}}

</$list>

ButI have way to many tags to use this effectively...

This doesn't use checkboxes but select menu's and generates a filter that can be copied to a list of your design-- or you can grab the select code from it and alter it for checkboxes if you're confident with digging into code.  It's only 2 stage but does AND, OR & NOT

Here's a little experiment I just cooked up:

\define maketagfilter() tag[$(currentTiddler)$]

<style>

.columns8 { display:block; -moz-column-count:8; -moz-column-gap:1em; -webkit-column-count:8; -webkit-column-gap:1em; font-size:60%; line-height:1em; }

.columns4 { display:block; -moz-column-count:4; -moz-column-gap:1em; -webkit-column-count:4; -webkit-column-gap:1em; font-size:80%; line-height:1.4em; }

</style>

__''SELECT TAGS:''__<br>

@@.columns8

<$list filter="[all[tiddlers+shadows]tags[]sort[]]">

   <$checkbox tiddler="selectedTags" index=<<currentTiddler>> checked=<<maketagfilter>>

      uncheckactions="""<$action-setfield $tiddler="selectedTags" $index=<<currentTiddler>> />""">

         <$text text=<<currentTiddler>>/>

   </$checkbox><br>

</$list>

<$reveal text=<<filter>> type="nomatch" default="[all[tiddlers+shadows]]">

</$reveal>

</$wikify>

Copy the above into a tiddler and see what you get...

Update: FilterGenerator now supports both AND and OR searches

Here's the new code:

<style>
.columns8 { display:block; -moz-column-count:8; -moz-column-gap:1em; -webkit-column-count:8; -webkit-column-gap:1em; }

.columns4 { display:block; -moz-column-count:4; -moz-column-gap:1em; -webkit-column-count:4; -webkit-column-gap:1em; }

.tiny   { font-size:60%; line-height:1em; }
.small { font-size:80%; line-height:1.3em; }
</style>

I've also attached a TiddlyWiki file, based on empty.html, with the FilterGenerator already added

Big thanks. I've changed Glooms code according to my needs and it works all right. One suggestion would be to alter the code for the drop down fields to

<$list filter='[all[tiddlers]tags[]sort[title]]'>

so the Tags are listed alphabetically. In the far away future I'll try to implement the check boxes but that was too complicated for me right now. But I'll definitely put Eric code to good use then.

The Tiddler now looks like this.

<$select field='filter-field1'>
<$list filter='[all[tiddlers]tags[]sort[title]]'>
<option value=<<currentTiddler>>><$view field='title'/></option>
</$list>
</$select>
<$select field='filter-field2'>
<$list filter='[all[tiddlers]tags[]sort[title]]'>
<option value=<<currentTiddler>>><$view field='title'/></option>
</$list>
</$select>
<$select field='filter-field3'>
<$list filter='[all[tiddlers]tags[]sort[title]]'>
<option value=<<currentTiddler>>><$view field='title'/></option>
</$list>
</$select>



<$list filter="[tag{!!filter-field1}] +[tag{!!filter-field2}] +[tag{!!filter-field3}]">
<$link><$view field=title/></$link>
<br/>

{{||$:/core/ui/ViewTemplate/tags}}

</$list>
Enter code here...

The nice thing is that it shows the tag pills of the search results.

Juri,

Is there a default way to select a combination of tags so that only the tiddlers with said combination are shown? Or how can I get a list with Checkboxes to do this?

Search for tags by name, filter tiddlers by custom tag intersections

 

You can use the search box to search for tags by name in the Tags tab. For example, you remember a sauce recipe that could be used for chicken dishes, so you search for "sauce" and click on the tag icon next to sauces in the list because you are sure you added this tag to the tiddler (so it's a direct tag) and then search for "chicken", and you click the chain icon next to chicken in the list because you only know that it is related to the chicken topic somewhere, but you do not know the depth (ancestor tag).

[TiddlyTweeter]

Gloom that is very neat and interesting. Having a FILTER CONSTRUCTOR, even if it can't do everything, is really useful! 

I'm sure it could be a great learning tool too. I'll be interested to see if you go further with the idea.

Best wishes
