[TW5] how to get the list of fields of tiddler with value "yes"

[Siniy-Kit]

hi! I have a tiddler $:/_allvendors   with several fields sony="yes" Nikon="yes" dell="yes"  and so on.

how can I  collect all fields with "yes" value and render this tiddler into DOM and get macros <<allvendors>> to use it in filter [vendor[sony]][vendor[dell]][vendor[Nikon]]

I have been trying to find a way to do that directly for a while and haven't been able to come up with anything. You can use how I made the options checkboxes work on this site. Each checkbox puts the filter part associated with that box in a field when checked, and makes the field blank when unchecked, then to make the final filter you concatenate all of the filter strings together.

It is a roundabout way to do it, but I am starting to doubt that there is a direct way with what is currently available.

In the proud tradition of engineers everywhere: if you are given an impossible problem to solve, cheat.

Thank you Jeremy. Your macros is working, but I don't know how to modify it to my proposes  (I try many variants)

my idea was to make a list of checkboxes,

<$list filter="[is[current]tagging[]tag[$:/Note]each[vendor]get[vendor]]" variable="vendor">
<$checkbox tiddler="$:/_allvendors" field= <<vendor>>   checked="yes" > ''<<vendor>>''  </$checkbox><br>
</$list>

the position of checkboxes I save in $:/_allvendors tiddler in its fields. so, If  the checkbox of vendor Dell is checked (unchecked), I want o remove from list all tiddlers with  field vendor="Dell'

<$list filter="[is[current]tagging[]tag[$:/Note]!vendor[Dell]sort[stoimost]]"/>  if I check (uncheck) "Nikon" the list must look like <$list filter="[is[current]tagging[]tag[$:/Note]!vendor[Dell]!vendor[Nikon]sort[stoimost]]"/>

so I want to create filter modifying by the lists of checkboxes .

but I can't understand, how to put many $fieldname$ into my list.

This was a fun little problem to solve. The solution I've come up with isn't pretty, but it seems to work:

\define inner(fieldName)

<$set name="v" value={{!!$fieldName$}}>

<$list filter="[<v>regexp[^yes$]]" variable="x">

<$text text="""$fieldName$"""/>

</$list>

</$set>

\end

<$list filter="[<currentTiddler>fields[]sort[]]" variable="fieldName">

<$macrocall $name="inner" fieldName=<<fieldName>>/>

</$list>

The regexp is particularly egregious; it's needed because we don't have a straightforward way to test a title for equality.

Best wishes

Jeremy.

It's very difficult (for me) to follow what you're trying to achive. Do you have someting online where we can take a look anf maybe experiment?

[sini-Kit]

you can see my experiments here http://novye-podarki.ru/heeg203_vk2.html 

I try to make a simple selection by vendor in my tiddlywiki Shop http://novye-podarki.ru/

But I this variant it is not possible to add sort  or to add another field to include (country for example)
