I was trying to look up why my while loop wasn't working in a template, so I came looking for the 'template logic' documentation page. Turns out it does not exist anymore, even though it's still linked from the 'template tags' page. Here is the URL where the 'template logic' documentation is supposed to be: link

 

You mean this: https://community.invisionpower.com/4guides/themes-and-customizations/template-syntax/ ?

ah, very good, although there is no info on while loops. One liners work:

 {{while ($statement->fetch()) {  var_dump($exactMatchQuery);  } }}
