select2

[4ng3lp]

Hi,

congrats by this great extension. Its really cool.

btw i have a problem with select2. When i have $model and attribute and, at same time, the 'asDropDownList' => false i get this error "htmlspecialchars() expects parameter 1 to be string, array given"

here is my config:

    $pluginOptions =array(
        'multiple' => 'multiple',
        'placeholder'=>GxHtml::encode($model->getRelationLabel('nMunicipioses')),
        'minimumInputLength'=>2,
        'ajax'=>array(
            'url'=> Yii::app()->controller->createUrl('/municipios/ajaxSearch'),
            'dataType'=>'json',
            'data'=>'js:function(term,page){
                                  return {
                                    q: term,
                                    page_limit: 10,
                                  };
                                }',
            'results'=>'js:function(data,page){
                                  return {results: data};
                                }',
        ),
        'formatResult'       => 'js:function(data){
                 return data.name;
             }',
        'formatSelection'    => 'js: function(data) {
                 return data.name;
             }'

    );

$this->widget('yiiwheels.widgets.select2.WhSelect2', array( 'asDropDownList' => false, 'model'=>$model, 'attribute'=>'nMunicipioses', //'name' => 'Areas[nMunicipioses]', 'pluginOptions' => $pluginOptions ));

And if i set 'name' and unset 'model' the response is a string (csv) with the id's not and array.

i really stuck with these.

thanks

To me looks fine, I am not sure why is happening to you, maybe is due to the model attribute itself? Can you point me to the Line error? I need more debug information than just that line.

Hi Tony,

thanks for your time!

when try with this configuration:

        $this->widget('yiiwheels.widgets.select2.WhSelect2', array(
            'asDropDownList' => false,
            //'model'=>$model,
            //'attribute'=>'nMunicipioses',
            'name' => 'Areas[nMunicipioses]',
            'pluginOptions' => $pluginOptions
        ));

the problem come in the format of postback looks something like these -with the developer tools-

Areas[name]:Nom1
Areas[n_dealer_id]:1
Areas[price_add]:0
Areas[nMunicipioses]:11576,56490
yt0:Guardar

and then GxActiveRecord crash because Areas[nMunicipioses] isn't a array.

if try with this configuration:

<div class="form">

<?php $form = $this->beginWidget('GxActiveForm', array(
    'id' => 'areas-form',
    'enableAjaxValidation' => false,
));
?>

    <p class="note">
        <?php echo Yii::t('app', 'Fields with'); ?> <span class="required">*</span> <?php echo Yii::t('app', 'are required'); ?>.
    </p>

    <?php echo $form->errorSummary($model); ?>

        <div class="row">
        <?php echo $form->labelEx($model,'name'); ?>
        <?php echo $form->textField($model, 'name', array('maxlength' => 45)); ?>
        <?php echo $form->error($model,'name'); ?>
        </div><!-- row -->
        <div class="row">
        <?php echo $form->labelEx($model,'n_dealer_id'); ?>
        <?php echo $form->dropDownList($model, 'n_dealer_id', GxHtml::listDataEx(Dealer::model()->findAllAttributes(null, true))); ?>
        <?php echo $form->error($model,'n_dealer_id'); ?>
        </div><!-- row -->
        <div class="row">
        <?php echo $form->labelEx($model,'price_add'); ?>
        <?php echo $form->textField($model, 'price_add'); ?>
        <?php echo $form->error($model,'price_add'); ?>
        </div><!-- row -->

        <label><?php echo GxHtml::encode($model->getRelationLabel('nMunicipioses')); ?></label>
        <?php

        //echo $form->checkBoxList($model, 'nMunicipioses', GxHtml::encodeEx(GxHtml::listDataEx(Municipios::model()->findAllAttributes(null, true)), false, true));

        $pluginOptions =array(
            'multiple' => 'multiple',
            'placeholder'=>GxHtml::encode($model->getRelationLabel('nMunicipioses')),
            'minimumInputLength'=>2,
            'ajax'=>array(
                'url'=> Yii::app()->controller->createUrl('/municipios/ajaxSearch'),
                'dataType'=>'json',
                'data'=>'js:function(term,page){
                                      return {
                                        q: term,
                                        page_limit: 10,
                                      };
                                    }',
                'results'=>'js:function(data,page){
                                      return {results: data};
                                    }',
            ),
            'formatResult'       => 'js:function(data){
                     return data.name;
                 }',
            'formatSelection'    => 'js: function(data) {
                     return data.name;
                 }'

        );

        $this->widget('yiiwheels.widgets.select2.WhSelect2', array(
            'asDropDownList' => false,
            'model'=>$model,
            'attribute'=>'nMunicipioses',
            //'name' => 'Areas[nMunicipioses]',
            'pluginOptions' => $pluginOptions
        ));

        ?>

<?php
echo GxHtml::submitButton(Yii::t('app', 'Save'));
$this->endWidget();
?>
</div><!-- form -->

then this is the output:

[tonydspaniard]

Will have a closer look when i have time... apologies for the delay

[zwollander]

I have exactly the same problem !!!!

[4ng3lp]

hi @zwollander,

there's an easy workaround...

in the action at XXXXcontroller.php:

$relatedData = array(   'nCodigoPostals' => $_POST['Areas']['nCodigoPostals'] === '' ? null : $_POST['Areas']['nCodigoPostals'],);
if (is_array($relatedData['nCodigoPostals'])==false){
                $relatedData['nCodigoPostals']= explode(',',$relatedData['nCodigoPostals']);
}

I hope this will help

[tonydspaniard]

Solutions offered by @4ng3lp is actually the solution
