dropDownList: How to the selected on page refresh?

Archives Yii 1.0.x Discussions
1

I have a large form that I have split into two:

I strugged with this for longs hours already - looking for a solution :)

Form-1: with three drop downs States, Counties, and Cities; with a textbox, say Guest Estimates. All four fields are required. This form is in site/index using renderPartial(_form1)

Form 1 looks like



...


                <tr>


                    <td><?php echo CHtml::activeLabelEx($submission,'ansi'); ?></td>


                    <td><?php echo CHtml::dropDownList('ansi', isset($_GET['ansi'])?(int)$_GET['ansi']:0


                                      ,CHtml::listData($states,'ansi','name'),


                                       array('prompt'=>'Select State'


                                            ,'ajax'  => array('type'=>'POST' //request type


                                                ,'url'=>Yii::app()->baseUrl.'/county/counties_in_state' //url to call


                                                ,'update'=>'#county_num' //selector to update


                                                ,'success'=>'js:function(html){jQuery("#county_num").html(html);


                                                             $("#feature_id").attr("disabled","disabled");}',


                                        ))); ?>


                    </td>


                </tr>


                <tr>


                    <td><?php echo CHtml::activeLabelEx($submission,'county_num'); ?></td>


                    <td><?php echo CHtml::dropDownList('county_num', '', array()


                                      ,array('empty'=>'Select State First'


                                            ,'ajax'  => array('type'=>'POST' //request type


                                                             ,'url'=>Yii::app()->baseUrl.'/city/cities_in_county' //url to call


                                                             ,'update'=>'#county_num' //selector to update


                                                             ,'success'=>'js:function(html){jQuery("#feature_id").html(html);$("#feature_id").removeAttr("disabled");}',


                                        ))); ?>


                    </td>


                </tr>


                <tr>


                    <td><?php echo CHtml::activeLabelEx($submission,'feature_id'); ?></td>


                    <td><?php echo CHtml::dropDownList('feature_id','', array()


                                      ,array('empty'=>'Select County First'


                                      ,'disabled'=>'true'


                                                 ,'update'=>'#feature_id' //selector to update


                                    )); ?>


                    </td>


                </tr>


                <tr>


                    <td><?php echo CHtml::activeLabelEx($submission,'guest_estm'); ?></td>


                    <td><?php echo CHtml::activeTextField($submission,'guest_estm'); ?></td>


                </tr>


...

When Form-1 is submitted, I want to retain all the selections as-is for the drop downs. Although I fork to different view that does render partial to the same _form1 as in Site/index.



<?php


          if(isset($_POST['SubmissionForm'])) {


            $submission->attributes = $_POST['SubmissionForm'];


            $submission->type       = $_POST['type'];


            $submission->ansi       = $_POST['ansi'];


            $submission->county_num = $_POST['county_num'];


            $submission->feature_id = $_POST['feature_id'];


            //echo "<pre>";print_r($submission);


            if($submission->validate()) {


                $this->render('submission2', array('submission' => $submission


                    , 'etypes' => $etypes


                    , 'states' => $states


                )); die;


            }


            else {


                $this->render('submission1', array('submission' => $submission


                    , 'etypes' => $etypes


                    , 'states' => $states)); die;


            }


        }


        $this->render('index', array('submission' => $submission


                    , 'etypes' => $etypes


                    , 'states' => $states));


?>

In the SiteController I intercept them as :

            $submission->attributes = $_POST['SubmissionForm'];

            $submission->type      = $_POST['type'];

            $submission->ansi      = $_POST['ansi'];

            $submission->county_num = $_POST['county_num'];

            $submission->feature_id = $_POST['feature_id'];

This is one of the ajax action that returns Counties. How can I use selected =selected. I looked the forum thread and could not find anything.



<?php


    public function actionCounties_in_state()


    {   


        $data = County::model()->CountiesInState($ansi=$_POST['ansi']);


        $data = CHtml::listData($data, 'num', 'feature_name');





        // Determine user action based on data


        if (empty($data)) $data[0] = 'Select State First'; 


        else              $data[0] = 'Select County Now'; 


        ksort($data);





        foreach($data as $value => $name)    {


            echo CHtml::tag('option', array('value'=>$value),$name,true);


        }


    }


?>

Why not use activeDropDownList? It will help you remember the selections made previously. You also don't need to write those assignments one by one.

3

I ran into one problem with activeDropDownList.

How do I pass the data returned by the ajax call to the dependent drop down. I read pages of forum and the documents but I am not able to figure it out.

Thanks qiang, I tried again this time with trail and error, reuslt is the same :(

4

I already needed this too in other project in other frameworks.

And i think you must do it manual job here.

You'll need place some logic to reaload some dropdownlist which were previously filled.

5

This is a very promising framework. I wish all the data collections (Forms) were hashed out. It is easier to work around Data processing, Controllers and Models

I build a similar multl-dropdown dependent list (for countries and wine regions). Here is my code:

This is the javascript in the form/view:



var oCountry = document.getElementById( 'InventoryItem_wine_country_code' );


var oRegion = document.getElementById( 'InventoryItem_wine_region_code' );


var oSubregion = document.getElementById( 'InventoryItem_wine_subregion_code' );


var oVineyard = document.getElementById( 'InventoryItem_wine_vineyard_code' );





//	Hide them


$('#PIF_InventoryItem_wine_region_code,#PIF_InventoryItem_wine_subregion_code,#PIF_InventoryItem_wine_vineyard_code').hide();





$.ajaxSetup( { 'async' : false } );





function changeCountry()


{


	$('#PIF_InventoryItem_wine_subregion_code,#PIF_InventoryItem_wine_vineyard_code').hide();


	$('#InventoryItem_wine_region_code').load( '/Code/GetOptionData/parent/' + oCountry.value );


	if ( $('#InventoryItem_wine_region_code').attr('options').length != 0 )


		$('#PIF_InventoryItem_wine_region_code').show();


	else


		$('#PIF_InventoryItem_wine_region_code').hide();


	oRegion.focus();


}





function changeRegion()


{


	$('#PIF_InventoryItem_wine_vineyard_code').hide();


	$('#InventoryItem_wine_subregion_code').load( '/Code/GetOptionData/parent/' + oRegion.value );


	if ( $('#InventoryItem_wine_subregion_code').attr('options').length != 0 )


		$('#PIF_InventoryItem_wine_subregion_code').show();


	else


		$('#PIF_InventoryItem_wine_subregion_code').hide();


	oSubregion.focus();


}





function changeSubregion()


{


	$('#InventoryItem_wine_vineyard_code').load( '/Code/GetOptionData/parent/' + oSubregion.value );


	if ( $('#InventoryItem_wine_vineyard_code').attr('options').length != 0  )


		$('#PIF_InventoryItem_wine_vineyard_code').show();


	else


		$('#PIF_InventoryItem_wine_vineyard_code').hide();


	oVineyard.focus();


}





function buildLabelName()


{


	_year = document.getElementById( 'InventoryItem_year_nbr' ).value;


	_varietal = document.getElementById( 'InventoryItem_wine_varietal_code' );


	_varietal = _varietal.options[ _varietal.selectedIndex ].text;


	_subRegion = document.getElementById( 'InventoryItem_wine_subregion_code' );


	_subRegion = _subRegion.options[ _subRegion.selectedIndex ].text;


	_vineyard = document.getElementById( 'InventoryItem_wine_vineyard_code' );


	_vineyard = _vineyard.options[ _vineyard.selectedIndex ].text;


	


	_out = _year + ' ' + _varietal + ', ' + _vineyard + ' Vineyard, ' + _subRegion;


	document.getElementById( 'InventoryItem_label_name_text' ).value = _out;


	_sName = document.getElementById( 'InventoryItem_name_text' );


	if ( '' == _sName.value )


		_sName.value = _out;


}

And my form definition:



					echo CPSActiveWidgets::simpleActiveBlock( CPSActiveWidgets::CODEDD, $_oItem, 'wine_country_code', array( 'onchange' => 'changeCountry()' ), 'Country', null, 'country' );


					echo CPSActiveWidgets::simpleActiveBlock( CPSActiveWidgets::CODEDD, $_oItem, 'wine_region_code', array( 'onchange' => 'changeRegion()' ), 'Region' );


					echo CPSActiveWidgets::simpleActiveBlock( CPSActiveWidgets::CODEDD, $_oItem, 'wine_subregion_code', array( 'onchange' => 'changeSubregion()' ), 'Subregion' );


					echo CPSActiveWidgets::simpleActiveBlock( CPSActiveWidgets::CODEDD, $_oItem, 'wine_vineyard_code', array( 'onchange' => 'buildLabelName()' ), 'Vineyard' );

CPSActiveWidgets is an extension of CHtml which I wrote. It builds the entire <div class="simple"> block and outputs the form field. It's part of my psYiiExtensions Yii extension (in the extensions portion of this site). Here's the code:

The CODEDD type is what I use. It's a "code" dropdown. In every web site I set up, I have a "code" table with code names and values. The definition is attached. I've also attached my model and controller.

Here is what I did to work around this situation.

Say I have 3 drop downs for

  1. States

  2. Counties (Sate has Many counties)

  3. Cities (County has Mas Cities)

Step1: Initial Page load, as usual

a. Paint Drop-Down States

b. Counties Empty, gets data from 'a', Ajax when State change

c. Cities Empty, gets data from 'b', Ajax when County change

Step2:

Problem: Submit the form, form remembers Drop-Down Sate only

Solution: Use the Model or ModelForm to make the data

Example:



<?php


<div class="simple">


    <?php echo CHtml::activeLabelEx($event,'ansi'); ?>


    <?php echo CHtml::activeDropDownList($event, 'ansi', CHtml::listData($states,'ansi','name'),


                   array('prompt'=>'Select State 1st'


                        ,'ajax'  => array('type'=>'POST' //request type


                        ,'url'=>Yii::app()->baseUrl.'/county/counties_in_state' //url to call


                        ,'update'  => '#EventForm_county_num' //selector to update


                        ,'success' => 'js:function(html){jQuery("#EventForm_county_num").html(html);


                        $("#EventForm_city").attr("disabled","disabled");}',


            ))); ?>


</div>





<div class="simple">


    <? $counties = ($event->ansi) ? County::model()->CountiesInState($event->ansi) : array();?>


    <?php echo CHtml::activeLabelEx($event,'county_num'); ?>


    <?php echo CHtml::activeDropDownList($event,'county_num', $counties


                  ,array('empty'=>'Select County 2nd'


                      ,'ajax'  => array('type'=>'POST' //request type


                     ,'url'=>Yii::app()->baseUrl.'/city/cities_in_county' //url to call


                     ,'update'=>'#EventForm_city' //selector to update


                     ,'success'=>'js:function(html){jQuery("#EventForm_city").html(html);$("#EventForm_city").removeAttr("disabled");}',


            ))); ?>


</div>





<div class="simple">


    <? $cities = (($event->ansi)&&($event->county_num)) ? City::model()->CitiesInCounty($event->ansi, $event->county_num) : array();?>


    <?php echo CHtml::activeLabelEx($event,'city'); ?>


    <?php echo CHtml::activeDropDownList($event,'city', $cities


                                      ,array('empty'=>'Select City 3rd'


                                            ,'class'=>'select200'


                                                 ,'update'=>'#city' //selector to update


                                    )); ?>


</div>

It is UGLY because Model is in View BUT it works!

Hope it help you :)

Could you give me some insight on how you did it? I’m trying to duplicate what you did by creating a simple dropdown and making the second dependent. I have this for my code…


<div class="simple">


<?php echo CHtml::dropDownList($boycott,'isCap', array(true =>'Cap', false=>'No'),

array( 'prompt'=>'Upper or Lower',

'ajax' => array(

'type' => 'POST', //request type

'url' => Yii::app()->baseUrl.'/isCap', //url to call

'update' => '#letter', //selector to update

'success' => 'js:function(html){jQuery("#letter").html(html); $("#letter").removeAttr("disabled");}',

//'data'=>'js:javascript statement' 

//leave out the data key to pass all form values through

))); 

?>

</div>

<div class="simple">

<? $letter = ($event->isCap) ? Letter::model()->LetterCapped($event->isCap) : array();?>

<?php echo CHtml::DropDownList($boycott, 'letter', $letter, array('empty' => 'Char', 'update'=>'#letter', 'class' => 'select200' )); ?>

What am I doing wrong?
