I have created a list of keywords that can be used throughout the site by adding an Advanced list to whatever page requires it and then adding to the pool of keywords as needed.
What I am having trouble with is when I want to separate these keywords to display them in a "Tag" Section. Each one is displayed in a CSS tag.
What I am getting is one tag displayed but with all the keywords in comma separated format.
I believe that I need to use an "explode" instead of a "join" (Correct me if I'm wrong...) But I am unclear on how that looks and if there is more coding to it. The example above works great for the page code meta tag "keywords" as it even has the comma separation in the echo. But not for what I am attempting elsewhere in the page display.
Thanks in advance for your help

Hi Michael,
Using 'join' creates a string from a list using the character(s) selected to attach them (in this case a comma).
Using Explode does the reverse, with the arguments otherwise the same.
What I think you're aiming to do is this:
This will create a link for each tag from each record.
Let me know if this helps,
Tom

Thanks Tom,
Im hoping this was a typo problem:
I am thinking the /endforeach; is actually a ?endforeach .... Not sure at all about the ; ....
I tried to fix it and got verified code with and without the ; But returned an error message: PHP Notice: Array to string conversion
So I see its close to a fix but I need a little more help [laugh]
Thanks Michael

Hi Michael,
You're right about the typo, it should be a "?" instead of a "/". The semi-colon at the end of the "endforeach" statement isn't technically necessary, but it won't cause any errors either. The semi colon is just used to end a statement, but in this case the ?> would end the statement anyway. It's a more a matter of style than anything.
The reason you're receiving the error is that explode() expects a string for it's second argument, but getListLabels() returns an array. If the "keywords" field is a multi value list (either drop down or checkbox) you can actually access all the labels using the :labels pseudo field like this:
Hope this helps
