This is an example for setting up a comment form for posting comments for logged in users only, using Fox and AuthUser


Prerequisites: install AuthUser, Fox and FoxDelete.

Add following to config.php, $FoxPagePermissions should be set for the group or page in which comments should be posted (in this example it is for all pages in group Test):

if ($AuthId) {
  $Author = $AuthId;

$Conditions['authuser'] = '\$GLOBALS["AuthId"]==\$condparm';

$FoxPagePermissions['Test.*'] = 'add,delete';



Page Site.AuthUser should be configured with user ids and their passwords, or users and passwords set up in a different way.

Add to Site.FoxForms this Fox comment form code:

(:fox cbox put=below mark=!!Comments template=Site.FoxTemplates#comment:)
Subject: (:input text heading size=60:)
'''Your Comment:'''
(:input textarea comment cols=60 rows=6:)
(:input hidden author value='{$AuthId}' :) (:input submit post "Add Comment":)
(:foxend cbox:)

Add to Site.FoxTemplates this comment template:

(:div1 class=messagehead:)
[-{$$(date d.m.Y - H:i)}-] &nbsp; (:if expr auth admin or authuser {$$author}:){[foxdelrange]}(:if:)

Add to each page or the GroupHeader (or GroupFooter) this markup for the comment form:

(:if authid:)Logged in as '''{$AuthId}''' - [-[[{*$FullName}?action=logout| (log out)]]-]
(:foxform Site.FoxForms#commentform :)
(:else:)Please [[{*$FullName}?action=login|log in]] to add comment!

Add to pub/css/local.css some styles (taken from CommentBoxPlus styles css):

/* styling of commentbox entries */
#message { clear:both; }
.messagehead, .journalhead {
            margin:1em 0 0 0;
            padding:0 0 0 3px;
            border:1px solid #ccc;
.messageitem, .journalitem {
            border-left:1px solid #ccc;
            border-right:1px solid #ccc;
            border-bottom:1px solid #ccc;
.messagehead { background:#f0f0f0; }
/*use the following if message head should be same as message item */
/* .messagehead { background:#eef; border-bottom:none; } */
.messageitem { background:#f7f7f7; }


  • The comment box form is set up for use with AuthUser.
  • It has no author field, as author is set via login with the AuthId of

the user.

  • You need to log in to see the comment form.
  • The delete link will only show for the logged in user's posts, and

for the admin (logged in as admin).

  • You may wish to tighten security by making sure only logged in users are allowed to post, but not allowed to fully edit pages. Follow instructions for AddingAuthLevels
