Hello,

I'm trying to implement some funcionality in the quiz form. For do that I've change the textbox 'subnet' for a select where have an array of all subnet of my organitation.

One of the array options have 'Others ranges of ip' that means that the user have to type the ip manually in another textbox named 'other_ip'.

The problems is that cannot acces to data field submited to change the value of subnet for the other_ip when this option has selected. And when the forms load I need access to the data value to comprobe if the select has this option available and has to put into the textbox. The value of the 'other_ip' textbox is not writen into database, because I've to use the select for do that.

Any help would be "so much" apreciated.

Thank's and regards

Some captures to explain more this problem:

and Some code :

unset($option_subnet);
$option_subnet = array();
$options_subnet[''] = "All sites are allowed";
$options_subnet['172.17.1.0/24'] = "Room 22";
$options_subnet['172.17.2.0/24'] = "Floor 33";
$options_subnet['1'] = "Other IP Range";

$mform->addElement('select', 'subnet', get_string("requiresubnet", "quiz"), $options_subnet);
$mform->setType('subnet', PARAM_TEXT);
$mform->setHelpButton('subnet', array("requiresubnet", get_string("requiresubnet", "quiz"), "quiz"));

$mform->addElement('text', 'other_ip', get_string('other_ip', "quiz"));
$mform->setHelpButton('other_ip', array('other_ip', get_string('other_ip', "quiz"), "quiz"));
$mform->setType('other_ip', PARAM_TEXT);
$mform->disabledIf('other_ip', 'subnet', 'neq', 1);

¿How can initialize 'other_ip' textbox?
¿Can access field data there?

You need to add a set_data method to the form class. Or, possibly, you coudl use the data_preprocessing function. Yes. data_preprocessing is the way to go here, I think.

Hi I do it!!, Thanks

I add this code to mod_form.php

============================

$quizsubnet = get_field('quiz', 'subnet', 'id', $this->_instance);

if (!isset($options_subnet[$quizsubnet])) {
   $mform->setDefault('other_ip', $quizsubnet);
   $defaultValues['subnet'] = array('1');
  } else {
          $defaultValues['subnet'] = array($quizsubnet);}

$mform->setDefaults($defaultValues);

=============================

and this other in the lib.php (mod\quiz dir)

=============================

function quiz_process_options(&$quiz) {
    $quiz->timemodified = time();
    if ($quiz->subnet == 1)  { $quiz->subnet=$quiz->other_ip; }

=============================

this lines do the job very well,

Thank's and regards.
