/* show tooltip

function stooltip( x, y, html ) {
if ( html == null ){
html = '<?php
if ( empty( $user_ID ) ) {
printf( __('You can NOT perform this function.

<a href="%s" style="color:red">Login</a> if you have an account. Do NOT have an

account? <a href="%s" style="color:blue">Create One</a>.', 'fbe' ),
$fbe_utilities->get_login_link(),

$fbe_utilities->get_user_register_link() );
} else {
printf( __('You can NOT perform this function.

<a href="%s" style="color:red">Sign in</a> with another account ', 'fbe' ),
$fbe_utilities->get_login_link(),

$fbe_utilities->get_user_register_link() );
}?>';
}

var winW = 630, winH = 460;

if ( parseInt( navigator.appVersion ) > 3 ) {
if ( navigator.appName=="Netscape" ) {
winW = window.innerWidth;
winH = window.innerHeight;
}
if ( navigator.appName.indexOf("Microsoft") != -1 ) {
winW = document.body.offsetWidth;
winH = document.body.offsetHeight;
}
}

// aligh x
if( x + 250 > winW ) {
var leftAligh = 250 - ( winW - x ) + 17;
x = winW - 250;
jQuery('.stooltip-pointer').attr( 'style', 'left: ' + leftAligh +

'px;');
} else {
jQuery('.stooltip-pointer').attr( 'style', '');
}
jQuery('#scontent').html(html);
jQuery('.stooltip').attr( 'style', 'position: absolute; top: ' + y + 'px;

left: ' + x + 'px');
jQuery('.stooltip').show();
return false;
}
</script>
<div class="stooltip" style="display:none;" >
<div class="stooltip-pointer">
</div>
<a class="sclose-it stooltip-dismiss">

I'm confused... what?

Do you want to disable the login function, as you said in the thread title, or do you want logged-out users (guests?) to be able to comment?

Either way, the code you posted is probably irrelevant.

 

I want logged-out users (guests?) to be able to comment Nico.

 

Comment means suggestion.

change the if statements that check if empty on the user id, then give them anonymous or default info, and post the comment

 

Can you write a sample code. I don't know writing php. You mean this field?
if ( empty( $user_ID ) )

 

if ( empty( $user_ID ) ){
$user_ID = "Anonymous"

if i can see the rest of your code, everything, i can do it for you. pm me.
