Drupal 7.x

Hello All,

I am starting on Drupal 7 and the Forms API, and I'm making my first form.

What I want is to have a textfield that is #required => true and visible only if a checkbox is checked. If the checkbox is unchecked, the textfield must be invisible and not required.

It seems like a pretty basic case. Is there a way to do that without having to do it manually in the _validate function ?

Right now, I have a checkbox and a textfield with the #states parameter set to be visible only when the checkbox is checked. By itself, this is working fine.

My trouble comes when I try to set the #required parameter for the textfield. If I set it to true, then I cannot submit the form, even if the field is invisible.
So, I set the #required parameter of the textfield to a condition on the checkbox value, but checking or unchecking the checkbox does not make the red '*' appear, since the form is not rebuilt just by checking a checkbox.
I figured I needed to make an AJAX call to reload the field, so I added a #prefix and #suffix with a div on the textfield, and set an ajax call on the checkbox, returning the $form["mytextfield"] element to replace the div.

I had made numerous changes to files. I changed the host file. I changed http file and the vhost files. I also made the change to sites.php and I made a folder for site1 and site2. I copied the default.settings.php in both locations and changed the name to settings.php. I also added the appreicate alias's in apache.

Where can I found in database, some list of javascript files weights? I want to add my javascript file but I don't know which weight I have to add to it. My js file needs that another js files are loaded first so it can use its functions and commands.

Thanks for any advice

I need to make taxonomy term pages that have multiple views (giving them a layout that's more like a front page). I want to do this for some vocabularies and not others.

I'm stuck on doing this. It seems like there's many approaches but I can't figure them out. For instance, I'm trying to use a node display (views) for the page and attach blocks to that with Context. But I can't figure out how to pass the taxonomy argument to the blocks.

What are my options for developing an e-commerce site, starting within the next couple of weeks? Is D7 ready or should I stick with D6 and ubercart?

Any views welcome

Thanks
Terry
