[TYPO3-project-formidable] Multiple values from LISTBOX

[Manuel Rego Casasnovas]

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
