RE: inserting checkboxes into a db
this worked well. thank you very much
No. Fields with the same name name return a comma-delimited list when more
than 1 is checked. Also, a checkbox is not True or False, it is Undefined or
Value (of value=#checkbox_value#).
In your case, the hidden field should be present on forms with checkboxes
and provide, as you surmised, a defualt value of 0.
Use IsDefined('FORM.checkbox_name') in the UPDATE to determine whether to
updaytre the field.

Subject: RE: inserting checkboxes into a db
input type=hidden name=c1 value=0
input type=checkbox name=c1 value=a
input type=checkbox name=c1 value=b
So the hidden sets the default value, right? Here's what I did.
on the page:
input type=hidden name=#checkbox_name# value=0
input name=#checkbox_name# #checked# type=checkbox id=#checkbox_name#
value=#checkbox_value#
and on the UPDATE page, I left it as is:
cfif structKeyExists(form,'mandate')
cfset session.mandate = form.mandate
mandate = cfqueryparam value=#session.mandate#
cfsqltype=CF_SQL_NUMERIC,
/cfif
So, whenever the checkbox exists, it'll either input this the checkbox value
or it's hidden field, because the checkbox won't overwrite it. right?
oh, I just checked that and it sorta works. If it's not checked, it works
fine. If it's checked, then it puts out 38352 in the value, rather than the
1 it's supposed to be. I suppose it's having problems with two fields being
named the same.
While I don't know if this is how you meant for me to implement it, it
seemed intriguing.

RE: inserting checkboxes into a db
I have a single file that's supposed to enter form data from several pages into a database. It checks to see if a form exists and if it does, then it enters it's value into the database. The problem that I'm running into is that when checkboxes aren't checked, they don't exist with structKeyExists(form,'the_checkbox'). If I'm on a page that has a checkbox and it's not checked, I want to set the value to 0, but if I'm on a form without any checkboxes, I want to leave the value in the database alone. I'm trying to use this UPDATE page for the several pages that make up a section because I'd rather not make a UPDATE page for each screen. You will have to have some way of tracking within your form data whether there was originally a checkbox in the page. One easy way to do this is to simply add a hidden form field within that page.

You will have to have some way of tracking within your form data whether there was originally a checkbox in the page. One easy way to do this is to simply add a hidden form field within that page. So, I guess the hidden field has to have a value that indicates the page, rather than just true and false. Because if I have one page with checkboxes and it just sets the hidden field to true then it'd be true for other checkboxes on the update page. ~| Logware (www.logware.us): a new and convenient web-based time tracking application.
