Show Tweets
Three different settings:
- User Timeline
- User + Friends Timeline
- Search
User Timeline shows the latest tweets from a specific Twitter User.
User + Friends Timeline shows the latest tweets from the Twitter User + his/her friends.
Search shows results from a Twitter search. See below.
Twitter Username / Password
Needed when you show Tweets from User Timeline or User + Friends Timeline.
Search String
Specify this when you want to show Tweets from a Search. You can configure the search criteria to return tweets from specific users, certain hashtags etc etc. The full Twitter Search Syntax can be used.
Number of Tweets
Controls how many Tweets to show in the module.
Link to
Controls where the Twitter User icon link goes. You can link it to the Twitter User's home page or to the current tweet itself.
Tweet Area Rows
How many rows in the textarea where the user enters the new tweet.
Tweet Form
Whether to show the tweet form or not below the tweets.
Shorten URL's
The URL's can be shortened automatically when you tweet using tinyurl.com.
Cache Time
A Twitter account is limited to 100 calls per hour for the API. If your website is busy then it's easy to exceed this limit. Use caching to reduce the number of calls to the Twitter API. Set Cache Time=0 to use no caching. (Time in minutes)
Note! If you do change search criteria etc in the module configuration - use the clean cache link below to empty the cache to see the change.
Module ID
The module ID is needed when you have more than one module instance on your website. Set the Module ID to a unique setting for each Module instance.
Password Map
You can map a fake password to a real password if you want. Useful when you want to let users post tweets using a common Twitter account, but you don't want to give out the real password.
Syntax:
fakepassword||realpassword
If you have more than one password that you wish to map, use comma delimiter between the passwords, like this
fakepassword1||realpassword1,fakepassword2||realpassword2
