Make Multi-row variable set mandatory and limit number of entries

Eash1 · ‎12-10-2018

Hello Experts,

I am using Multi row variable set in my catalog item and it works perfect but i am stuck on below 2 requirements.

Does anyone have any insights to it ?

How to make sure at-least one entry is selected as part of Multi row variable set. I tried to do a on-submit and later read through docs that it is not supported
How to limit number of entries ? like just 10

Thank you,

Easwar

Hi Easwar,

I was looking to make a sure at least one entry exist in the multi row variable set. I don't know if you found a way to it.

I came with the solution of a on submit client script (I think what the doc refers to is for on submit that would run after each entry being added). Here is a code snippet that I was able to use to make sure there is at least one row:

function onSubmit() {
	if(g_form.getValue('internal_name_of_variable_set') == '[]'){
		g_form.addErrorMessage('You must enter at least 1');
		return false;
	}
}

g_form.getValue returns a JSON of the variable set, so simply by checking if it is an empty array, I was able to block submission in that case.

I think you could solve your second requirement with this (parsing the JSON and doing a length validation: array.length < 11). However this is not the best User experience as you are checking this on submit while the user already entered more than 10 entries.

Hi,

For the first one, Add a UI Policy on the Variable Set and make it Mandatory.
For the second one, set "Variable Set attributes" in the variable set to "max_rows=10"
