How can I make attachments required if a particular box is checked?

Hi,

Have you seen this post?

number of attachments based on calculated field value  

I would add the GetNumberOfAttachments function to the forms Custom Javascript section, change the CSS Class as shown on the Attachments control and then add a validation rule that checks if the "Existing Maps" checkbox is checked or not in combination with the outcome of the GetNumberOfAttachments function, alerting as appropriate.

Cheers,

Mark

I saw that post, however, I am still completely lost with how to factor in my titles and the checkbox. My JS knowledge is very minimal.

for yes/no checkbox validation formula should simply be

cbMapsExists && GetNumberOfAttachments("AttachmentControlClass") < 1‍

cbMapsExists is Named Control reference for the checkbox

AttachmentControlClass is CSS class assigned to attachment control

Thank you for the reply!

I set the CSS name on the Attachments as AttachmentControlClass.  And I have the checkbox name as "ArethereexistinsMaps."  Below is the validation formula I added to the Yes/No checkbox.

When I check the box and submit the form with no attachments, I do not get an error.  I am still able to submit without attachments.

Anything I am missing?

as mentioned above, you have to add checkbox to the formula as Named Control reference, not just simple type it in

it has to get red in formula builder.

I do not see a Named Controls tab...

Am I inputing this formula in the wrong area?  I have put this under the validation on the yes/no checkbox...

you have to create validation rule assigned to (the best) attachment control

Thank you for your continued help and patience...

I think I have it set now.  However, it's still allowing me to submit the form without an attachment.  No error message.  Anything else I need to do?  Does it not automatically activate?

- can you post configuration of "ArethereexistinsMaps" control

- can you post configuration of attachment control?

- have you added script for GetNumberOfAttacments() function into from settins >> Custom javascript?

- open developer console (F12) and run/reload the from. check the developer console whether there are not reported any errors

ArethereexistingMaps config:

Attachments config:

I added this Custom JS:

F!2: No reported errors

- remove validation function content from ArethereexistinsMaps' control settings and set its 'use custom validation' to no

- you likely do not call validateAttachements() function anymore, so remove this function from custom javascript.

- copy&paste function GetNumberOfAttacments() from following link into custom javascript

Thank you for your continued help!

I've pasted that formula in my JS. Though, I'm sure I did it wrong (as it's still not working). 

Below is a screenshot of the JS and the Validation rule:

with removing validateAttachements() function from custom javascript I meant to remeve it including its body, not just its name.

do it once again: clear whole custom javascript content and paste there just GetNumberOfAttacments() function from the link provided.

Still not working:

can you post screenshot of attachments control configuration dialog with formatting section expanded?

where did you come to this syntax of CSS class definition???

put there simply:

nf-form-input AttachmentControlClass

validate‌ attachment‌   ‌ ‌ ‌ ‌

Yes!!!  It works!  Thank you for all of your help!
