    1. COGeneral tip: if you post a wall of code and just throw a line number at is, INDICATE WHERE THAT LINE IS. Don't force us to count lines manually. As well, don't use regexes for parsing html. You end up with hideous monstrosities like this. Use DOM instead.

    2. CO"Only variables should be passed by reference in get_id.php on line 27" - I guess it doesn't have to do with wampserver. I guess it would be the php-version that matters.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
