[CB] Prevent certain members PMing each other

[Peter]

Was a code request which may be useful for others.

If you want to stop user A PMing user B, then you would add both usernames into the array (bit in bold), so when one of them goes to PMing the other, the form will be disabled.

<script type="text/javascript">
<!--

// Array of the members who cannot PM each other
var iMembers = ["username", "username", "username", "username"];

function preventPM(){
    var gotUser = false;

    for(m = 0; m < iMembers.length; m ++){
        if(iMembers[m] == document.cookie.match(/\buser=(\w+)/)[1]){
            gotUser = true;
            break;
        }
    }

    for(m = 0; m < iMembers.length; m ++){
        if(iMembers[m] == document.postForm.to.value.replace(/\s/g, "") && gotUser){
            for(e = 0; e < document.postForm.elements.length; e ++){
                if(document.postForm.elements.item(e).name == "to"){
                    continue;
                }
                document.postForm.elements.item(e).disabled = true;
            }
            break;
        } else {
            for(e = 0; e < document.postForm.elements.length; e ++){
                document.postForm.elements.item(e).disabled = false;
            }
        }
    }
}

if(document.postForm && location.href.match(/=pmsend/i)){
    document.onkeypress = preventPM;
    document.onkeyup = preventPM;
    window.onload = preventPM;
}
