[Fwd: [Fwd: Re: How to add "selected" attribute to select list <option>tag]]

28 Nov 2007

      Once again, I spoke too soon.  Once I shut down FF, and also tried IE and Opera, it looks like the form is working fine.  I 
cleared out the Drupal cache, but not the browser cache.  Looks like I'm good to go.

Thanks for the tip, Greg (you too, Sarah).

I guess I spoke too soon.  I did it as an array

#default_value => array(2,3)

and upon viewing the source, I discovered that it adds the selected="selected" attribute to my option tags like I want.  The
problem is, the items aren't being highlighted on the screen.

so this code:

*
  * Define the project permissions settings form
  */
function project_permissions_form($project_nid, $project_name) {
   $form['#base'] = 'project_permissions_form';

   $form[$project_nid] = array(
     '#type' => 'fieldset',
     '#title' => $project_name,
     '#collapsible' => TRUE,
     '#collapsed' => FALSE,
   );

   $form[$project_nid]['projects'] = array(
     '#type' => 'textfield',
     '#title' => t('Project name'),
     '#maxlength' => 30,
     '#size' => 30,
     '#default_value' => $project_name,
   );

   $form[$project_nid]['users'] = array(
     '#type' => 'select',
     '#title' => t('Users with access to project'),
     '#description' => t('Select users to be asssigned to the project'),
     '#options' => _get_user_list(),
     '#multiple' => TRUE,
     '#default_value' => array(2,3),
   );

   $form[$project_nid]['nid'] = array(
     '#type' => 'hidden',
     '#value'=> $project_nid,
   );

   $form[$project_nid]['submit'] = array(
     '#type' => 'submit',
     '#value' => 'Submit'
   );
   return $form;
}

gives me this HTML:

<div class="form-item">
  <label for="edit-users">Users with access to project: </label>
  <select name="users[]" multiple="multiple"  class="form-select" id="edit-users" ><option value="1">admin</option><option
value="2" selected="selected">bwald</option><option value="3" selected="selected">testuser</option><option
value="4">Brian</option><option value="5">NickH</option></select>

  <div class="description">Select users to be asssigned to the project</div>
</div>

So why wouldn't the items be highlighted on the screen?

Hmmm, getting closer, but I can't seem to get it to work.  No matter what I try, I can't get it to select anything.

Here is what my select list looks like (in HTML)

<option value="1">Name 1
<option value="2">Name 2
<option value="3">Name 3
<option value="4">Name 4
<option value="5">Name 5

The value is the user's uid. number That being the case, what would i use for #default_value?  I've tried things like

'#default_value' => array(1 => 'Name 1')
'#default_value' => 1
'#default_value' => 'Name 1'

but I can't get any of them to work.  Any ideas?

Thanks.

Make the #default_value an array of the keys of the options you want
selected.
$form['item'] = array(
'#type' => 'select',
...
'#options' => array of all options,
'#default_value' => array of keys from above options.

);
Check

/5#default_value for more info.

<option>tag
Well, I'm back again, and this time I have a question about attributes
for select options in a form.  I have a form that has a 
select element (multi-select) that lists users.  The form is for some
admin settings for a module.  When the form is displayed, I 
need to be able to highlight specific options in the list based on data
returned from a query.  I've been looking all day, and 
haven't been able to figure it out.  There is the #attribute key, but it
is for the field as whole (at least as far as I can 
determine), and doesn't work for each individual <option> tag.
If anybody could point me in the right direction, I would appreciate it.
Thanks.
Steve
