Hi

I'm creating <select> lists fine in QuickForm2 but can't work out how to set one of the items as selected.

Am creating thus:
Code:
   $specialism =    $fsText->addElement(
    'select', 'specialism', null , array('options' => $specialism_options, 'label' => 'Specialism' )
      );
      


populating the data with an array:
Code:
$specialism_options = array(
      'acc' => 'Accountancy', 'off' => 'Office services',  'exec' => 'Executive search'
      );   
      


I'm assuming the selected values is something to do with the $attributes array which I've tried creating in place on the NULL

Code:
 $specialism_att = array('selected' => 'exec');


but this has no affect...

Any ideas? As I can't believe doing something so essential should be so difficult!

Thanks

In HTML_QuickForm a method setSelected() exists, but it is recommended to use $form->setDefaultValues().

According to the phpdoc comment in the HTML_QuickForm2_Element_Select_OptionContainer class, you can use the addOption() method to mark an item as selected:
Code:

   /**
    * Adds a new option 
    *
    * Please note that if you pass 'selected' attribute in the $attributes
    * parameter then this option's value will be added to <select>'s values.
    *
    * @param    string  Option text
    * @param    string  'value' attribute for <option> tag
    * @param    mixed   Additional attributes for <option> tag (either as a
    *                   string or as an associative array)
    */
    public function addOption($text, $value, $attributes = null)


I haven't checked it, but according to what happens in this method, setDefaultValues() should still work in QF2. (This method might have another name in QF2, though.)

thank you...

I'd been looking at this from the wrong angle. I think the QF2 version is addDataSource and I was using that for other inputs - simply not clicking that I need this for <selects> as well!

Cheers - all working now!

I am also looking for a solution but addoption is not a good one as it add a new option instead of just marking as selected an existing one and for adddatasource i havent foud how it could solve the problem.

Does anyone have a solution to put a selected value on QF2?

You can find an example of using addDataSource() here:
http://www.joomlaportal.de/geloeste-themen-komponenten/126178-submit-und-ausgabe-einer-quickform2-formular-komponente.html
(it's a German forum, but you should get the idea from the example code there)

Thanks for the answer but i still dont see why and how to use adddatasource for this job, i found a workaround but its unelegant :

Code:
function selected($object, $array, $selected) {
   foreach ($array as $id => $name) {
      if ($id == $selected) {
       $object->addoption($name, $id, selected);
      } else {
       $object->addoption($name, $id);
   }}
}



And i call it this way :

Code:
$usercountry  = & $fsinfos->addelement('select', 'country', null, array('label' => 'Country:')); selected($usercountry, $countrieslistar, $userar[0][usercountry]);

Do you have experience with HTML_QuickForm 3.x? Setting default values (including selected values of select boxes) was done via setDefaultValues(). In QF2 this concept was made more flexible by data sources. And therefore, addDataSource() is the way to pass default values to forms with QF2.

I never user QF 3.x and for the adddatasource can you give me an example to elect an item on a select because documentation isn't really clear on that.

Thanks by advance.
