1: listbuilder - pre-checking some checkboxes?

Posted by Cathy Sarisky on 03/19/04 08:07 PM

Hello all,

First: listbuilder rules, thank you. Being able to produce really NICE looking tables with so little typing is wonderful. :)

Second: A question. Is there some straightforward way to pre-check some of listbuilder's checkboxes? I'm pulling rows out of the database and would like to check some of them based on a value pulled from the db. Feel free to point me at a package that does this already if one exists. I've looked at the docs (thanks Jade) and api-doc but am not seeing anything that seems to do what I want.

Thanks!

/Cathy

I know this post is 2 years old, but I just had the same question and found 1 way to do it, so thought I'd post it here for the next wanderer...

First, set -has_checkboxes which tells the listbuilder that you will create your own checkboxes.

Then, in the -elements section, create an element like this:

-elements {

  checkbox {

    display_template {<input type="checkbox" name="yourlistkey" value="@yourmultirow.yourlistkey@" @yourmultirow.checkbox@ />}

  }

...

}

Then, extend your multirow with the 'checkbox' variable.

db_multirow -extend {checkbox} yourmultirow .... {

  if { $my_criteria } {

    set checkbox "checked"

  } else {

    set checkbox ""

  }

}

Replace yourmultirow with the name of your multirow.
Replace yourlistkey with the listkey column of your list
