Recursion help

[Anon]

Hello,

I am migrating from ASP to php and I am trying to convert old ASP threaded message board script to a php script.

I know that there are already custom forum scripts available for download and a couple of visitors to this forum have kindly sent me the web addresses.

However, my message board is quite simple and all I need is away to get a list of replies to a post (parent id) and format them out with the necessary indentations (reply ids).

I would like to be able to try and get my head around php recursion so if anybody has any references for a simple recursion function for a threaded message board I would greeatly appreciate any help.

Thank you,

Brian MacCoilin

How did you do it in ASP? It should be feasible to translate that, at least as a first cut. Certainly, it would put more meat on the question (there are so many ways a threaded discussion board could be implemented).

Hello Hayley,

Thanks for taking in the time to reply. I later was able to get the recursion working to format out the replies with correct indentation based on a translation from the ASP script.

Initially,I had declared the variable used to store the results returned by "mysql_query" function as "global", and this was the reason why my recursion function was exiting the "while" loop when it reached the end of 1st branch of the tree,instead of continuing with the required iteration. Removing the global declaration produced the desired formating.

All the best,

Brian.
