just to make it more clear

i am getting a dbmulirow result

and before i print them out onto the page i have to modify the string via a regexp - i have a proc that does it but how can i call this from the adp page directly ?

hope ive been clear

thanks

Is there a reason why you do not want to do it in the .tcl page?

<%= [my_proc params] %>  and
<% [my_proc params] %>

print results or don't

might be 'old school' :) but it works for me.

Lots of %this_stuff% these days. Guess that's when the flow is reversed - tcl runs then you ns_adp_parse ..

Hi,

Expounding on Malte's suggestion, you can do this:

db_multirow users fetch_users {
    select email from parties
} {
    regsub (.*)@(.*) $email {\1 at \2} email
}

This changes the value of the email variable in the multirow and you would not need to run any Tcl in your adp.

In other words, @users.email@ would contain "ache9829 at mail.usyd.edu.au" in your case.  No Tcl needed.

Hope this helps.

thanks for that

the reason why i need it from the adp page is because

i have my adp setting up a grid for my results from db_multirow already and thought if i can call the function from within the adp page itll just be easier

thanks guys

I've been missing a warning here :)

Don't call tcl procs from your adp page. It's a leftover from old days and somehow defies the whole sense of a templating sense. Code goes into the tcl file, markup into the adp file. (Well, that's a rule of thumb at least!)
