Customizing a random quote script

[AlterPoser]

Okay I need help with this script I found, I'm trying to customize it so members who sign in don't have to manually enter there name. I really don't know anything about javascript so any help would be great.

I didn't really want to mess around with it 'cause I know even one small mistake can just throw everything off.

What are you trying to do? You want to show a random message everytime your member visits your page?

This is better done with PHP using the rand() function.

How are you showing the member's name?

[Nile]

Yes, rangana is right, here this should do half of it:

<?php
$random = array('One','Two','Three');
if(!logged_in()){
  echo $random[rand(0,count($random))];
}
?>

Change the highlighted to the function/variable that says if the user is logged in or not.

o-O What? Well I wanted the greetings that flickr has when you log in, so I looked around and found THIS but you have to manually enter your name for it to work. I'm using Ning Networks and instead of having my members manually enter their names I want it to recognize their user account name when they log in. . .I think I just made this a whole lot more complicated.

Ughz

Does your host support PHP? And how are you logging in to your site? PHP? Free login script?

Does Ning allow you to enter your own code? I played around with Ning a while ago and don't remember that being an option. The most they let you do was edit the CSS.

Well they allow you to enter codes threw pages, content boxes, and the analytics section. I think that's pretty much it as for the PHP, I have no clue.

In a JS way

var say = ["Quote1", "Quote2", "Quote3"]
alert(say[Math.floor(Math.random() * say.length)]);
