Hi Popolvuh,
I see the other post in French. As stated earlier, only one is necessary.
To use the Function Plugin on a field example:
member_validation_id.
Step 1: define the function in the Script (JS) section which is found below the Storage section and by clicking on the orange chevron in the lower right hand corner. So you need to define your logic and message but here is the basic idea:
myvalidation = function(){
var text = $(this).attr("member_validation_id").value;
var msg;
if(text!=2){
msg="NO";
}
return msg;
}
Step 2: Set the Validation (#3) option in the Content Type Manager to Function and give the name of the function that you defined the Step 1.
Validation: Function
Function Name: myvalidation
Hope that helps,
Randy
