Query fine but something I don't understand

Recommended Posts

I made a php form to edit articles in my MySQL database, with a $_GET passthrough of variable $id, which represents the primary key for the table.

At the end of the form, after the hidden "submitted" input, I have a line[code]echo '<input type="hidden" name="id" value="' . $id . '" />[/code]

The query won't perform the update without this line, and I just wondered what it does, theoretically.  I was having a terrible time until I started looking for scripts and saw this somewhere.

Apparently, your script is using this FORM input value to figure out which database record to edit -- if you don't submit this field with the form, it won't "work".
