DispForm Button to Append People Picker with Current User

[Celeste Garcia]

I have a requirement to allow users to add their name to a multi people picker field by clicking a button in DispForm. Is this possible? I have tried several approaches and cannot find a way to update a record form DispForm….

Hi,
You can add this code to the Custom JS in your DispForm:

function addMeToPP(){
    var item, currPP, newPP, uItem;
    item = spjs.utility.getItemByID({"listName":_spPageContextInfo.pageListId,"id":spjs.dffs.data.thisItemID,"viewFields":["PeoplePicker2"]});
    currPP = item.PeoplePicker2;
    if(currPP.indexOf(_spPageContextInfo.userId+";#") === 0 || currPP.indexOf(";#"+_spPageContextInfo.userId+";#") > -1){
        alert("Your have already been added to this field.");
    }else{
        newPP = currPP+";#"+_spPageContextInfo.userId+";#";
        uItem = spjs.utility.updateItem({"listName":_spPageContextInfo.pageListId,"id":spjs.dffs.data.thisItemID,"data":{"PeoplePicker2":newPP}});
        if(uItem.success){
            location.reload();
        }else{
            alert(uItem.errorText);
        }
    }
}

You must change “PeoplePicker2” with the field internal name of your field.

Then add this code to a “HTML section” in one of your tabs:

<input type="button" value="Add me to the PP" onclick="addMeToPP()" />

Let me know how this works out.
