    1. COWhat are you trying to do with those string concatinators within a string? As I don't see anything sanitizing your data: Sanitize your data to prevent mysql injection. Does `$_POST[$product_name]` contain the value that has to be put into the product_name field of your row? In that case you can do that in a double-quotes string like so: `"some string {$_POST[$product_name]} some more string"`

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.
