PHP Enhancing a Simple PHP Application Cleaning URLs with Rewrite Rules Adding A Trailing Slash

Trailing slash rewrite rule

I am stumped. I have tried every combination I can think of, based on the pattern from the "shirts/#/" example but also taking into account that there are no query string ID numbers in this code challenge. The syntax for this was not exactly covered in the lesson. I have searched the web for ideas on how to solve, and have not come up with a satisfactory result. I'm sure I'll be all like "D'oh" when I see the answer, but it's presently beyond my reach.

I think this is what you're looking for. You want to match "flavors" and add a "/", so you put flavors (everything between the start "^" and end "$" of what you're looking for) in parentheses as a back reference. You then want to add a "/" to what you have back referenced. You do this with "/$1/". "$1" is your back reference and you add a "/" after it. I hope that makes sense. I passed with the code below.

RewriteEngine  On   
RewriteRule ^flavors/$ /all_flavors.php
RewriteRule ^(flavors)$ /$1/ [R=301]

Thanks, Wade. It makes perfect sense, and I must have had a typo in mine.
