WordPress Custom Fields

[realph]

Hey there,

I’m not too familiar with PHP and the Custom Fields in WordPress but I wanted to give something a go.

I write a few articles on my site and sometimes use other sites as a source for stories, I always link back to them (as you do) at the bottom of the article (below).

What I’d love to do is add a custom field called "source" and throw the source link in the value (below).

Doing this I’d like it to create a button at the top of the article like this (below).

With it linking to the article I threw in the Custom Field value earlier.

Now I’ve managed to make this work to an extent, check it out here: http://bitthirsty.com/battlefield-bad-c … wwii-level

The problem is that it appears on every article, even the ones that don’t have a source attached to it. I’d like it to only appear on the articles where I’ve set a source in the Custom Field, could anyone help me solve this.

This is the PHP I’m using for the button, like I said I don’t know much about PHP so sorry if it makes no sense whatsoever.
