Don’t forget nested functions in CFWheels

Posted on by

Occasionally I forget clever little things, like using functions as argument values.

Here’s a small snippet which I ended up using when doing a blog front page, where I wanted to strip the tags out of the blog body, truncate it to 300 characters, and then add a ‘read more’ link at the end of the paragraph with an ellipsis.

There’s a load of nice little functions in CFWheels for this – stripTags(), truncate() and linkTo().

Here’s what the helper in the loop ended up as:

#truncate(
  text=stripTags(body), 
  length=300, 
  truncateString="#linkTo(
      text='... Read More »', 
      route='blog', 
      action='view', 
      key=id)#"
)#

    Agreed this is very nice and tidy. You can also remove the quotes and hashes from around the call to linkTo.

    Ah yes of course – good call :)
