Using 'jr:choice-name' for multiple selections

[KerryKang]

Hello all, 

Is there any syntax using 'jr:choice-name' for all/ any selections in multiple choices? I hope to get labels in the attributes no matter how many answers are selected. I am aware that 'at' can be used to pull out the value in the specific order, but not sure how I can apply it to the entire answers.

Hi Kerry,

Unfortunately this isn't possible using jr:choice-name(), which will only use the label to populate the attribute if one selection is made. Did you come up with a workaround or alternative to this workflow? If so, please share it on the forum.

Thanks,

Brett

Hi Brett/Kerry,

I am totally new to GIS domain. So happens I came across this website with the extensive methods to invoke within XLS for Survey123 Connect. Within the PDF there is a section describing the jr:choice() for multiple choice questions. Below is the example used to select exactly three colors:

Table 1: Survey

type	name	label	hint	constraint	constraint_message
select_ multiple colors	color_prefs	What colors do you like?	Select three	count-selected(.)=3	Select exactly three.

Table 2: Choices

list_name	name	label
colors	red	Red
colors	blue	Blue
colors	yellow	Yellow
colors	green	Green
colors	orange	Orange
colors	purple	Purple

Table 3: Survey with jr:choice()

type	name	label	hint	calculation
select_multiple colors	color_prefs	What colors do you like?	Select three.
calculate	color_0			jr:choice-name( selected-at(${ color_prefs}, 0), ’${color_prefs}’)
calculate	color_1			jr:choice-name( selected-at(${ color_prefs}, 1), ’${color_prefs}’)
calculate	color_2			jr:choice-name( selected-at(${ color_prefs}, 2), ’${color_prefs}’)
note	color_note	Selected colors:	${color_0} <br> ${color_1} <br> ${color_2}

Snapshots from the PDF are attached here for your reference. Pardon for the resolution, it is snipped based on the PDF. For more information you can visit this link and download the PDF for its full information: https://docs.getodk.org/

I was able to use such concept on my form to produce the expected output.

Hopefully it helps!

I revived this only to provide a more simple solution for this.

You only need one hidden field using concat formula parameterized like this:

concat(jr:choice-name(selected-at(${your_question},0), '${your_question}'), ', ', jr:choice-name(selected-at(${your_question},1), '${your_question}'),', ', jr:choice-name(selected-at(${your_question},n), '${your_question}'))

You will have to increase n as many times as answers you want to capture.

This expression will generate a list like this

selection 1, selection 2, selection n, ....

Of course you can replace ', ' with any character you want to use for separate the choices, you could use ' | ', or ' - ', etc

The XLSForm will look  like this

type	name	label	calculation
hidden	your_field_name	The label you want to use	concat(jr:choice-name(selected-at(${your_field_name},0), '${your_field_name}'), ', ', jr:choice-name(selected-at(${your_field_name},1), '${your_field_name}'),', ',jr:choice-name(selected-at(${your_field_name},2), '${your_field_name}'))

The column bind::esri:fieldType will be esriFieldTypeString and bind::esri:fieldLength can be 1000 length.

Later you can filter this on a dashboard with a filter applied to your hidden field using the contains parameter with the choice you want to show.

Hope this helps.
