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

[anderj39]

I have very little JS knowledge.  I can follow some, but am lost with most.  So I've read a similar question, only rather than a checkbox, the example shows attachments being required based on the value in a dropdown list.

If the "Are there existing Map(s)?" box is checked, I need at least one attachment to be required.  Please help! Thanks!

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...

[emha]

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

[anderj39]

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
