Maq

It's shorthand for an if/else block. Basically, it checks to see if the last character is a '-', if it is, concatenate nothing, if not, it will add a '-' on the end of the string. Read this - http://us3.php.net/ternary

Can you post the relevant code for this error?

thread ------------- name id replies ------------- text id t_id You would know that all replies with a specific t_id are linked to a specific thread.

Not sure, I don't use PHPMyAdmin.

In the future, please use tags around your code.

For what?

I know I sound redundant but, I agree with everyone else. As long as you're polite, know why and how to fix it, you should correct 'false info'.

Google and read some articles: http://www.mikebernat.com/blog/Setting-Up_a_Relational_Database_in_MySQL http://dev.mysql.com/tech-resources/articles/intro-to-normalization.html Yes, but I already told you, I don't think you want to do that. Have a table with replies that links each reply to each article/form/blog w/e it is.

Let's back up. I don't think you want to create a new column every time someone makes a reply. Your tables should be relational, meaning, you can relate each table in such a way to extract the specific information needed.

'to' is a MySQL reserved word: http://dev.mysql.com/doc/refman/5.1/en/reserved-words.html If you can, change your column names, otherwise, you must put backtics around `to` every time it's used.

You haven't tried what I suggested, please turn on error reporting.

In the future, please use tags around your code.

Temporarily turn on error reporting. Put these 2 lines directly following your opening <?php tag: ini_set ("display_errors", "1"); error_reporting(E_ALL);

I'm not downloading your code, post the relevant part(s).

You can use trim. If you want to do something else, then provide a more detailed explanation and/or examples.
