#173087

The demo and quickstart of JA_Elastica have a twitter box with the last tweet, but it is in fact just a custom module using fixed text.

How can I recreate it to actually query twitter?

Also can the JA_Elastica forum be moved to public like the JA_Purity forum?

Thanks in advance.

#436276

Nearly solved it myself. The only thing left to do is figure out what to change to style the time of the tweet correctly. I ran out of time before figuring it out.

1. Install a plug in that allows you to post PHP code. I used sourcerer.
2. Create a module in “position-7” using Module Class Suffix “grid-double mod-contrast contrast-blue”
3. Insert the following PHP code. This is modified from code written by Jonathon Nicol that you can see documented here.
I cut this from sourcerer so the formatting is a little off. I basically changed the classes of some items to match Elastica, changed it from being a list, and reduced it to only grab 1 tweet.

Hope this helps.
