htmlspecialchars() expects parameter 1 - Yii (echmultiselect)
htmlspecialchars() expects parameter 1 to be string, array given C:\xampp\htdocs\yii\framework\web\helpers\CHtml.php(98)The error only occurred when trying to apply the echmultiselect filter to the filter above the gridview.
Here's what I did to fix:
1. Went to the Yii framework folder and found the following file: yii\framework\web\helpers\CHtml.php
2. Modifed line 98 from "return htmlspecialchars($text,ENT_QUOTES,Yii::app()->charset);" to:
"return htmlspecialchars(print_r($text, true),ENT_QUOTES,Yii::app()->charset);"
Then you need to implement the echmultiselect extension in the view (my example shows adding it for site_status):
3. Added this php code to the view: $data= CHtml::listData(Nvdaily::model()->findAll(), 'blahblahblah', 'blahblahblah');
(but it should probably be in the model)
4. Made my 'columns' array look like this:
'columns'=>array(
'id',
'blah',
'blahblah',
array (
'name'=>'blahblahblah',
'filter'=> $this->widget('ext.EchMultiselect.EchMultiselect',
array(
'model' => $model,
'dropDownAttribute' => 'blahblahblah',
'data' => $data,
'options' => array('buttonWidth' => 80, 'ajaxRefresh' => true),
),
true // capture output; needed so the widget displays inside the grid
),
),
array(
'class'=>'bootstrap.widgets.TbButtonColumn',
),
),
