[Resolved] cformsII php mysql help!
i’m not a database hard coder, but i love wordpress so i’d like to know more.
i’m using wordpress + cformsII for a school website.
i have a form for each lesson, so students can subscribe to single lessons, and i have to manage a maximum number of students registrations, different for each lesson.
so in the plug-in backend i’ve set a maximum number of submission different for each form resulting in a “Registrations are closed” sentence after the number of submission is reached.
but now i’d love to have a counter for the number of seats left, such as “There are 2 more seats left, hurry up!”
i didn’t find an automatic way to do this so i’m trying to do a query directly on the database and having a numerical result to show on the page.
i’ve found that the number of submissions is stored in the new table
and the maximum number of submission set is stored in the table
field_nameis “Set the maximum number of students” and
sub_idis the number of the lesson.
so now, math should be simple: (maximum number students) – (registrations) = (number of seats left)
but my poor knowledge of MySQL won’t help me in getting the query works…
i tried different ways starting from here http://codex.wordpress.org/Function_Reference/wpdb_Class but i’m stuck.
thank you in advance.
