Creating a blog post with predefined content
Unfortunately Confluence doesn't support templates for blog posts. You can use a link with predefined content though, to automatically set up blog posts in a certain space and add a predefined title and content:
Step-by-step guide
Define the link to create a blog post:
https://your.path/pages/createblogpost.action?spaceKey=BVPROJ
add parameters like title, label
https://your.path/pages/createblogpost.action?spaceKey=BVPROJ&title=2014-MM-DD%20Teammeeting&labelsString=teammeeting
add HTML content by using an URL encoder tool, like http://meyerweb.com/eric/tools/dencoder/ and encode the HTML. Add it to your URL with the prefix "&wysiwygContent="
your result should look similar to this:
https://your.path/pages/createblogpost.action?spaceKey=BVPROJ&title=2014-MM-DD%20Teammeeting&labelsString=teammeeting&wysiwygContent=%3Ch2%3ETwitter%3C%2Fh2%3E%0A%3Cul%3E%0A%20%20%3Cli%3EIdee%3F%3C%2Fli%3E%0A%3C%2Ful%3E%0A%3Cp%3E%20%3C%2Fp%3E%0A%3Ch2%3EThemen%3C%2Fh2%3E%0A%3Cul%3E%0A%20%20%3Cli%3E%20%3C%2Fli%3E%0A%3C%2Ful%3E%0A%3Cp%3E%20%3C%2Fp%3E%0A%3Ch2%3EAnfragen%3C%2Fh2%3E%0A%3Cul%3E%0A%20%20%3Cli%3E%20%3C%2Fli%3E%0A%3C%2Ful%3E%0A%3Cp%3E%20%3C%2Fp%3E%0A%3Ch2%3EDiverses%3C%2Fh2%3E%0A%3Cul%3E%0A%20%20%3Cli%3E%20%3C%2Fli%3E%0A%3C%2Ful%3E
You may want to add this link as a button on a page with the Enterprise theme button macro.
