I'm using standard Yii dependent dropDownMenu (something similar to this). The logic is that current dropDown will define which element (next dropDown) will be updated with controller action.
echo CHtml::dropDownList('level_1', '', $arrayWithValues, aaray(
'ajax'=>array(
'type'=>'POST',
'url'=>Ccontroller::createUrl('myActionName'),
'update'=>'#level_2'
)));
My question is how can I change the update value after the action is executed? i.e the action find out that we need to populate DropDown Level_3 instead of Level_2.
echo CHtml::dropDownList('level_1', '', $arrayWithValues, aaray(
'ajax'=>array(
'type'=>'POST',
'dataType' => 'json',
'data'=>array('selected'=>'js:this.value'),,
'url'=>Ccontroller::createUrl('myActionName'),
'success'=>'js:function(data){
if (data.update==2){
$("#level_2").empty();
$("#level_2").append(data.items);
}
if (data.update==3){
$("#level_3").empty();
$("#level_3").append(data.items);
}
}'
)));
In your controller you'll have selected value as $_POST['selected'].
public function actionmyaActionName()
{
....
do what you need here
$items.=CHtml::tag('option', array('value'=>$value),CHtml::encode($state),true);
....
echo CJSON::encode(array(
'update'=>$update,
'items'=>$items
));
Yii::app()->end();
}
Form your options, define what to update.

I've inherited a piece of code from an old developer and currently trying to figure out the method behind how it submits.
I'm currently trying to get a quick fix in place where I hide one of his fields to get the form submitting, the issue I'm having is that I can't seem to set the dropdownlist to a default value, which should be United Kingdom, with the id 826 in the database.
echo CHtml::ActiveDropDownList($address, 'country_id', CHtml::listData(Country::model()->findAll(), 'id', 'name', 'continent'), array(
'class' => 'col-md-5 hidden',
'prompt' => 'Select Country',
'label' => 'something here',
'ajax' => array(
'type' => 'POST',
'url' => CController::createUrl('/user/UpdateRegions'),
'dataType' => 'json',
'data' => array('country_id' => 'js:this.value', 'YII_CSRF_TOKEN' => Yii::app()->request->csrfToken),
'success' => 'function(data) {
$("#Address_country_region_id").html(data.country_id);
$("#Address_country_region_id").removeClass(\'hidden\');
if($("#venue_id").val() === "") {
$("#Address_country_region_id").addClass(\'hidden\');
}
}',
)));
$path = CController::createUrl('/admin/user/UpdateRegions');
$id = $address->id;
// On Load
Yii::app()->clientScript->registerScript('ready', '
$.ajax({
type: \'POST\',
dataType : \'json\',
data: {\'country_id\': $(\'#Address_country_id\').val(), \'update_id\' : "' . $id . '"},
url: "' . $path . '",
success: function(data){
$(\'#Address_country_region_id\').html(data.country_id);
}
})
');
How do I get this dropdownlist pointing towards the country_id of 826 as the page loads so I can hide the field and pass the validation of the form.
regards.
this code you pasted does this:
the first part renders a dropdown which does an ajax request on change to /user/UpdateRegions to fill the dependent dropdown for the regions.
the second part does also an ajax request when the page is "ready". So that the region select is filled when the page is ready.
Your script should output the id 826 if you printout the current set id.
If not the value isn't correctly set to the address model.
echo $address->country_id;
If you want to set the default value you can do this at multiple places. e.g. in the controller 'before' the actual submitted value is set or in the model code itself (depends on your code e.g. if you have an additional form model which is extended from your activerecord model).
The correct line in your controller could be before something like this:
$address->country_id= 826;
before one of these lines in your controller
$address->attributes=Yii::app()->request->getQuery(get_class($address));
or
$address->attributes=Yii::app()->request->getPost(get_class($address));
or
$address->attributes=$_POST['address']; // or $_GET
If you have difficulties to find the correct position post some controller code.
I guess you could find some help also here

How can i get selected value of a drop down list in _form page to my controller page.
_form page
<?php echo $form->dropDownList($model,'prd_id',CHtml::listData(Category::model()->findAll(),
'cat_id','category')) ?>
I want to get the value of selected item in drop down in my Categorycontroller page.
Try like
<?php echo CHtml::activeDropDownList($model,'prd_id',CHtml::listData(Category::model()- >findAll(),array(
'prompt'=>'Select',
'ajax' => array(
'type'=>'POST',
'url'=>Categorycontroller::createUrl('action'),
)
)); ?>
Sounds like you need AJAX here:
If it is for a dependent dropdown then try this
http://www.yiiframework.com/wiki/24/
Even if it's not for a dependent dropdown the same principals apply with passing the selection to a controller.
echo CHtml::dropDownList('country_id','', array(1=>'USA',2=>'France',3=>'Japan'),
array(
'ajax' => array(
'type'=>'POST', //request type
'url'=>CController::createUrl('currentController/dynamiccities'), //url to call.
//Style: CController::createUrl('currentController/methodToCall')
'update'=>'#city_id', //selector to update
//'data'=>'js:javascript statement'
//leave out the data key to pass all form values through
)));
You can use this in controller:
First use var_dump after $_POST[MODELNAME]
then use
$rs = isset($_POST[MODELNAME]['prd_id']) ? $_POST[MODELNAME]['prd_id'] : array();
$value = (!is_array($rs)) ? explode(',', $rs) : $rs;
Assume I'm in my items controller.
Ok say I am in my view action (the url would be something like /items/view/10012?date=2013-09-30) which lists a list of items that belongs to a client on a given date.
I want to link to add a new item. I would use the htmlhelper like so:
echo $this->Html('action'=>'add');
In my add action I have a form which has fields like client_id and item_date.
When I'm in my view action I know these values as I am viewing the items for a specific client on a specific date. I want to pass these variables to my add action so it will prefill those fields on the form.
If I add a query string in my link ('?' => array('client_id'=>$client_id)) it breaks the add action as it will give an error if the request is not POST. If I use a form->postLink I get another error as the add action's POST data must only be used for adding the record, not passing data to prefill the form.
I basically want to make my link on the view page pass those 2 variables to the add action in the controller so I can define some variables to prefill the form. Is there a way to do this?
Here is my add controller code. It may differ in content a bit from my question above as I have tried to simplify the question a bit but the concept should still apply.
public function add(){
if ($this->request->is('post')) {
$this->Holding->create();
if ($this->Holding->save($this->request->data)) {
$this->Session->setFlash(__('Holding has been saved.'), 'default', array('class' => 'alert alert-success'));
return $this->redirect(array('action' => 'index'));
}
$this->Session->setFlash(__('Unable to add your holding.'), 'default', array('class' => 'alert alert-danger'));
}
$this->set('accounts', $this->Holding->Account->find('list'));
$sedol_list = $this->Holding->Sedol->find('all', array(
'fields' => array(
'id', 'sedol_description'
),
'recursive' => 0,
'order' => 'description'
)
);
$this->set('sedols', Hash::combine($sedol_list, '{n}.Sedol.id', '{n}.Sedol.sedol_description') );
}
Why not use proper Cake URL parameters?
echo $this->Html->link('Add Item', array(
'action' => 'add',
$client_id,
$item_date
));
This will give you a much nicer URL like:
http://www.example.com/items/add/10012/2013-09-30
And then in your controller, you modify the function to receive those parameters:
public function add($client_id, $item_date) {
// Prefill the form on this page by manually setting the values
// in the request data array. This is what Cake uses to populate
// the form inputs on your page.
if (empty($this->request->data)) {
$this->request->data['Item']['client_id'] = $client_id;
$this->request->data['Item']['item_date'] = $item_date;
} else {
// In here process the form data normally from when the
// user has submitted it themselves...
}
}
I am having a problem with the form select helper. On my page I have two forms.
One is a quick search form. This one uses state_id.
Upon searching in URL: state_id:CO
This will auto select the correct value in the drop down.
However, when I search with the advanced form. The Field is trail_state_id and
in URL: trail_state_id:CO
For some reason it will not default it to the correct value. It just resets the form to no selections. The values are searhed properly, just the form helper is not recognizing that a field with the same name in the url is set. Any thoughts?
<?php
class Trail extends AppModel {
public $filterArgs = array(
array('name' => 'state_id','field'=>'Area.state_id', 'type' => 'value'),
array('name'=>'trail_state_id','field'=>'Area.state_id','type'=> 'value'),
);
}
?>
in URL: trail_state_id:CO
<?php
echo '<h4>State*:</h4><div>'.$this->Form->select('trail_state_id', $stateSelectList, null, array('style'=>'width:200px;','escape' => false,'class'=> 'enhanced required','empty'=> false));
?>
Using the 3rd argument in the helper you can set a default. I did it the following way;
echo '<h4>State*:</h4><div>'.$this->Form->select('trail_state_id', $stateSelectList, (empty($this->params['named']['trail_state_id']) ? null: $this->params['named']['trail_state_id']), array('style'=>'width:200px;','escape' => false,'class'=> 'enhanced required','empty'=> false));
Previously I've created a question where I was wondering how to set selected value for dependent dropdown. That was easy, man adviced me just set second parameter.
echo CHtml::dropDownList('OpenLessons[Building]', $buildingClassID, $buildingList,array(
'ajax' => array(
'type'=>'POST',
'url'=>CController::createUrl('ajax/floorList'),
'update'=>'#OpenLessons_Floor',
)));
echo CHtml::dropDownList('OpenLessons[Floor]',$model->Class_ID, array(),array(
'ajax' => array(
'type'=>'POST', //request type
'url'=>CController::createUrl('ajax/roomList'),
'update'=>'#OpenLessons_Class_ID',
)));
echo CHtml::dropDownList('OpenLessons[Class_ID]',$model->Class_ID, array());
where $buildingClassId is value of select. So that works fine for first select. But how can I set the same for dependent ones? When I look at it's code it looks like this:
<select name="OpenLessons[Floor]" id="OpenLessons_Floor">
</select>
I expected it to have some options, because I set default value for first one. So even if I put as second parameter of seconddropdown some value it wouln't be selected.
Any advices/suggestions?
UPDATE I'd mention that I don't see at XHR console call of floorlist. How can I make it?
UPDATE
$(document).ready(function()
{
$('#OpenLessons_Building').trigger('change');
$('#OpenLessons_Building option').trigger('click');
}).on('change','#OpenLessons_Building',function()
{
console.log('changed');
}).on('click','#OpenLessons_Building option',function()
{
console.log('clicked');
});
Tried like this. Both actions - change and click has happened because I can see output in console, but the dependent arrays are still empty.
You should use $("#OpenLessions_Building").on("change", function() { your code here });
The trigger function was actually does is execute the action (change or click in your case) of the dropdown as soon as the page loads.
