[TYPO3-project-formidable] Multiple values from LISTBOX

[Luc Muller]

Hi Manuel.

Thanks for this small addition to formidable.
It's great to see that peoples are involved in the project :)

The multiple choice listbox is something that should have been implemented 
inside formidable sometimes ago, but, for now, it was just a missing 
feature.

We just forgot to put it in :p

I think jerome is going to get that inside Formidable Core.

For Now I'm think of something else.

You allow people to select multiple option in listbox.

Did you think about adding the possibility to display <optgroup> ?

This is not really used inside a lot of project, but it can be useful when 
listboxes are really big.

As you were modifying the listbox renderlet, may you have a look at this 
point and see what's possible with this.

By our side, we are working on totaly other aspect on formidable at the 
moment, but it's gonna be a next feature, I'll Add it right now in the todo.

Thanks a lot :)

Hi,

I have modified the tx_rdtlistbox class to add this new feature, now I
can create a LISTBOX renderlet that allow me to do multiple choice.  The
renderlet code is the next:
<renderlet:LISTBOX name="my_field">
  <multiple>true</multiple>
    <data>
      <items>
        <item caption="" value="" />
        <item caption="A" value="0" />
        <item caption="B" value="1" />
      </items>
    </data>
  <custom>size="10"</custom>
</renderlet:LISTBOX>

To do this, I've copied the source code from renderonly tag and I've
added the next function to the class tx_rdtlistbox:
function _isMultiple() {
  return ($this->oForm->_isTrue("/multiple/", $this->aElement));
}

And I've modified the _render method in this class:
  if($this->_isMultiple()) {
    $sInput = "<select name=\"" . $this->_getElementHtmlName() . "[]\"
multiple ";
  } else {
    $sInput = "<select name=\"" . $this->_getElementHtmlName() . "\" ";
  }
    $sInput.= "id=\"" . $this->_getElementHtmlId() . "\"" .
$this->_getAddInputParams() . ">" . $sOptionsList . "</select>";


I attach the file for this new class in this mail.


Jerome, if you want you can add this change to your classes. I think
that is a new feature that can be interesting for more people.


Best regards,
   Rego
