SharePoint Json If statement for visibility based on Other Colums being empty/ filled

[Stanislawo]

I've been trying to create a SharePoint list in which a button is visible when two of the columns of that row have a value entered. I've tried looking for answers but can't find anything that has worked.

I'm trying to check that the column name Approvers for that item is not empty (for which I'm trying to check that it is not equal to null). Ideally I would like to check that Sender is not null but any help would be appreciated. Here's what my JSON file looks like:

{

"$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",

"elmType": "button",

"txtContent": "Send",

"customRowAction": {

"action": "executeFlow",

"actionParams": "{\"id\": \"9de29813-f1b8-4ebc-870e-fe3a7a4472af\"}"

},

"style": {

"background-color": "purple",

"color": "white",

"visibility": "=if([$Approvers] == \"\" ,'hidden','visible')"

}

}

As you can see the approvers field doesn't change the visibility. Any help would be much appreciated!!

@Stanislawo "visibility": "=if([$Approvers] == '' ,'hidden','visible')" where the =='' uses single quotes.

Thank you so much!! I'm a bit gutted that I didn't try that, do you know how I could incoroporate an and statement into the if statement? Exact same thing but for another column called senders.

@Stanislawo just add && [$Senders]=='' for and or use pipes || for or

@RobElliott Thanks a lot, I've this but unfortunately it looks like the date column always has a value, I tried finding what default value that may be but couldn't find anything. Here's a visual representation of the issue I've got:

Here's the code too:

{

"$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",

"elmType": "button",

"txtContent": "Send",

"customRowAction": {

"action": "executeFlow",

"actionParams": "{\"id\": \"9de29813-f1b8-4ebc-870e-fe3a7a4472af\"}"

},

"style": {

"padding": "0px 25px",

"cursor": "pointer",

"border": "none",

"color": "white",

"font-weight": "550",

"background-color": "#0078d4",

"text-decoration": "none",

"font-size": "14px",

"text-align": "center",

"width": "85px",

"visibility": "=if([$Approver] == '' || [$Sender] == '' || [$Deadline] == '','hidden','visible')"

}

}

I only want the button to show when all 3 values have been set but, SP seems to think that there's always a value under the date column. But maybe I've just coded it wrong. Any advice would be much appreciated!!

@Stanislawo 

"visibility": "=if([$Approver] == '' && [$Sender]=='' && Number([$Deadline]) == 0 ,'hidden','visible')"

@Stanislawo There are couple of ways to check if date column is empty or not. 

One way suggested by @RobElliott using Number() function works well (+1).

Other ways are to use the toString() function OR directly refer to column name like ![$Deadline].

Check: SharePoint JSON formatting: Check if date & time column is blank/empty
