Hi folks,

I'm currently developing a template with many options for Joomla 1.6 and created some custom formfields for it.

Now I would like to access the values of other formfields of the templates parameters form from within the getInput() function of my custom formfield "savecolorpreset".

Is this possible? - I took a look at the sources of formfield.php and form.php and then thought,
Code:
$this->form->getValue('left_column_background_color');
should do the trick but it doesn't return any value.

Any hints?

Many thanks in advance for every reply,
yours Henri

Hi again folks,

I tried a lot of things, read the JForm API but could not get back a formfield-value with getValue(...).

But what now worked for me ist the following:
Code:
foreach($this->form->getFieldset() as $field) {
   if ( $field->name == $this->form->getFormControl() . '[params][body_background_color]' ) {
      $arrayColorFormfields[$field->name] = $field->value;
   }
}

I can get my things to work now but it would be nice if someone could even point me to the right direction to get back formfield values directly with getValue(...).

Yours Henri

Hi Byteconcepts,

Try putting this class above your JFormField extender class.

Code:
class Params {

   private $fields;
       
   public function __construct($fields) {
      $this->fields = $fields;
   }
   
   public function get($param) {
         
      foreach($this->fields as $field) {
         if ( $field->name == 'jform[params]['.$param.']' || $field->name == 'jform[params]['.$param.'][]' ) {
            return $field->value;
         }
      }
      
   }
   
}


With the above class added add the following to the beginning of your getInput() function.

Code:
$params = new Params($this->form->getFieldset());


Now all you need to get the value of a param in your getInput() function is something like the following.

Code:
echo $params->get('backgroundColor');



Oh and thanks for posting your initial code it helped send me in a functional direction. ;)

Also, I imagine, haven't tested, the above will work in other extended JFormField class functions just add

Code:
$params = new Params($this->form->getFieldset());


to them as well.
