Hi ,
I have a CHtml::dropDownList in my View and I want to catch the current selected value in my
controller , how can I do that ?
echo CHtml::dropDownList('country_id','', array(1=>'USA',2=>'France',3=>'Japan'),
array(
'ajax' => array(
'type'=>'POST', //request type
'url'=>Yii::app()->baseUrl.'/index.php?r=allownce/dynamiccities', //url to call
'update'=>'#city_id', //selector to update
//'data'=>'js:javascript statement'
//leave out the data key to pass all form values through
)));
//empty since it will be filled by the other dropdown
echo CHtml::dropDownList('city_id','', array());
What code do it need to put in my controller class action function ?
I am very sure that I made a success POST to the allownce/dynamiccities function but
I have tried $_POST[‘country_id’] but value was not captured.
Thanks for any sharing.
Hi ,
I managed to do it and this are some of the changes
I disable the filters in my controller for temporary testing
//‘accessControl’, // perform access control for CRUD operations
I code the controller action function as follow
public function actionDynamiccities()
{
if ($_POST['country_id'] == '1') {
echo CHtml::tag('option',
array('value'=>'1') , CHtml::encode($_POST['country_id']),true);
echo CHtml::tag('option',
array('value'=>1) , CHtml::encode('test11'),true);
}
else
if ($_POST['country_id'] == '2') {
echo CHtml::tag('option',
array('value'=>2) , CHtml::encode('test2'),true);
echo CHtml::tag('option',
array('value'=>2) , CHtml::encode('test22'),true);
}
else if ($_POST['country_id'] == '3') {
echo CHtml::tag('option',
array('value'=>3) , CHtml::encode('test3'),true);
}
}
Make sure your code is after the line
<?php echo CHtml::beginForm(); ?>
Hi ,
Now I have another question, if I have a dropdownlist and I wish to populate to more than one
dropdownlist , i.e. MULTIPLE form element , such as dropdownlist2 , input_text1, input_text2 …
how to code in the controller ?
and at the view , the js:‘success’:function(html){jQuery("#city_id ").html(html);}
seems that it only take ONE html and fills in its value , so how can I get all the other
form elements value depend on this drop down selection ?

create array for all elements: dropdownlist2 , input_text1, input_text2 …
in Controller:
public function publicarScript()
{
$jsUrl = Yii::app()->getAssetManager()->publish('protected/controllers/yourFolder/YourClassController.js');
$cs = Yii::app()->clientScript;
$cs->registerCoreScript('jquery');
$cs->registerScriptFile($jsUrl, CClientScript::POS_END);
}
/*
* Ajax request
*/
public function actionYourFunctionNameHere() {
...
$arrayDataList = your datalist...
$value_text1 = ; your text1...
$value_text2 = your text2...
...
$rs['dropdown2'] = $arrayDataList1...
$rs['input1'] = $text_value1;
$rs['input2'] = $text_value2;
echo json_encode($rs);
}
in "YourClassController.js" on the same "yourFolder/YourClassController":
$(document).ready(function() {
// start here
$('#dropDown1').change(function(){
$.post('index.php?r=yourFolder/YourClassController/YourFunctionNameHere', jQuery(this).parents("form").serialize(), function(arrData){
eval("var obj="+arrData);
// populate the dropdown 2
str = "<option value=''>Select name...</option>";
$.each(obj.dropdown2, function(i, item){
str += "<option value="+item.id+">"+item.name+"</option>";
});
$('#dropDown2').html(str);
$('#input1').attr('value',obj.input1);
//...
});
});
});

look for my code:
JAVASCRIPT
$(document).ready(function(){
// Popula a dropdown
$("#serie").change(function(){
var idSerie = this.value;
$.post("index.php?r=pedagogico/avaliacao/PreencheDadosForm",{
idSerie:idSerie
}, function(dados){
eval("var dados="+dados);
// TURMA // Monta a estrutura de um SELECT
str = "";
$.each(dados.turma, function(i, item){
str += "<option value="+item.id+">"+item.codigo+"</option>";
});
$("#turma").html(str);
// DISCIPLINA // Monta a estrutura de um SELECT
str = "";
$.each(dados.disciplina, function(i, item){
str += "<option value="+item.id+">"+item.codigo+"</option>";
});
$("#disciplina").html(str);
// ETAPA // Monta a estrutura de um SELECT
str = "";
$.each(dados.etapa, function(i, item){
str += "<option value="+item.id+">"+item.codigo+"</option>";
});
$("#etapa").html(str);
// SEGMENTO
$("#segmento").attr('value',dados.segmento);
});
});
});
CONTROLLER ACTION

$crit = new CDbCriteria();

$serie = serie::model()->with('segmento')->find($crit);
