Iam having
<?= $form->field($model, 'parentid')
->dropDownList(ArrayHelper::map(User::find()->asArray()->all(), 'id', 'firstName'),
['prompt'=>'-Select a Parent-'])
?>
When i submit the form,iam getting parentid value is empty.
I have disable the dropdown by jquery
$("#register-parentid").attr("readonly", "readonly");
Im getting empty value and i have referred, as said , we cannot get the value from disable field. Then how can i get the values from disable.
Iam using same form for two functions. One for disable field and another one for non disable .
I tried lot. but i didn't get the solutions for this one.
Finally, I have playing with jquery.
When i submit the form, i have disabling the readonly field
$('button[type=submit]').on('click', function (event, attribute) {
$("#register-parentid").prop("disabled", false);
});

I wrapped my gridview with Pjax widget like this
\yii\widgets\Pjax::begin();
gridview
\yii\widgets\Pjax::end();
in order to make the gridview make ajax request when I click on each pagination.
I also use ['class' => 'yii\grid\CheckboxColumn'], in column as well.
and I find that when I'm on first pagination I checked some rows and then go to second page and check some rows but when I go back to first page what I've checked is gone.
My question is how can I keep all checkedrow for all pagination
With current conditions (Pjax, multiple pages, yii\grid\CheckboxColumn) it's impossible because of the way it works.
When you click on the pagination links all GridView html content is replaced by new one that comes from the AJAX response.
So obviously all selected checkboxes on the previous page are gone.
Few possible ways to solve that:
1) Write custom javascript and server side logic.
As one of the options, you can send AJAX request to server with parameter meaning that user has chosen to select all data for the bulk delete operation (or use separate controller action for bulk deletion). In this case actually we don't need to get the selected data from user, because we can simply get them from database (credits - Seng).
2) Increase number of displayed rows per page.
3) Use infinite scroll extension, for example this.
4) Break desired action in several iterations:
select needed rows on first page, do action (for example, delete).
repeat this again for other pages.
You can get selected rows like that:
$('#your-grid-view').yiiGridView('getSelectedRows');
[infinite scroll] : http://kop.github.io/yii2-scroll-pager/ will work good if you do not have any pjax filters. If you have filters also in play, do not use this plugin as it does not support pjax filters with it. For rest of the applications it is perfect to use.
Update1 : it seems to be straight forward than expected, here is the how I accomplished it
Add following lines to the checkbox column
'checkboxOptions' => function($data){
return ['id' => $data->id, 'onClick' => 'selectedRow(this)'];
}
Now add following JS to the common js file you will have in your project of the page where this datagrid resides
var selectedItems=[]; //global variable
/**
* Store the value of the selected row or delete it if it is unselected
*
* #param {checkbox} ele
*/
function selectedRow(ele){
if($(ele).is(':checked')) {
//push the element
if(!selectedItems.includes($(ele).attr('id'))) {
selectedItems.push($(ele).attr('id'));
}
} else {
//pop the element
if(selectedItems.includes($(ele).attr('id'))) {
selectedItems.pop($(ele).attr('id'));
}
}
}
Above function will store the selected row ids in the global variable array
Now add following lines to pjax:end event handler
$(document).on('pjax:end', function () {
//Select the already selected items on the grid view
if(!empty(selectedItems)){
$.each(selectedItems, function (index,value) {
$("#"+value).attr('checked',true);
});
}
});
Hope it helps.
I just solved this problem and it works properly with Pjax.
You may use my CheckboxColumn. I hope this can help. The checked items are recorded with cookies.
You can read the part with //add by hezll to understand how to fix it, because I didn't provide a complete general one.
Hope it works for you.

In Yii, I listed my table which is fetch from database in grid view.
'value'=> 'CHtml::radioButton("set_default",false,array(
"value"=>"$data->id",
"set"=>"1",
"disable"=>"disable",
"uncheckValue"=>null
))',
the above code I entered in normal radio button view, how do I fetch from database? Anybody help me?
CGridView lets you write any value inside row's column instead of normal database values. For modify column values, you need to add a function for value attribute. Inside of this function, you can access each data's attributes. In your case, You need to echo a radio button like this:
//$data refres to each data row in the CGridView
'value' => function ($data, $row) {
echo
CHtml::radioButton("set_default",false,array(
"value"=>$data->id,
"set"=>"1",
"disable"=>"disable",
"uncheckValue"=>null
)),
},
How I do not display empty and null rows in yiiframework with listview.
Many rows in database are null.When I want to show data in view.php I see many null rows.I see a data on the other page.
can I see just rows with data.
The CListView widget uses a template to render each row of data.
In the skeleton generated by Gii, the index.php file has a CListView widget that uses the _view.php file to display row data.
You only have to check if a field is null and don't show it.
If you are aking for the autogenerated view.php file, the default is CDetailView
At this place, you can use the "visible" element of the attribute item:
<?php $this->widget('zii.widgets.CDetailView', array(
'data'=>$model,
'attributes'=>array(
array(
'name'=>'field1',
'visible'=>$model->field1!=null,
),
..............
See attributes property of CDetailView and CListView
in your model, put a condition to filter null/empty values before rendering the result to your view.
public function search() {
// Warning: Please modify the following code to remove attributes that
// should not be searched.
$criteria=new CDbCriteria;
$criteria->compare('table_column', $this->tableColumn, false );
$criteria->condition .= "another_table_column IS NOT NULL"; //this will filter null values
Use the afterFind() method in your Model to change the value displayed in the view so that a null value is shown as "NA" or some other value like that.
I have a view file add_rates.ctp and in that there is one select box . when i change the optiion, it will make a ajax call and fetch some values from the controller and load an element in that view.
but my problem is iam not getting the parameter values in the element.
i am getting params in rates.ctp
$params=$this->params['pass'];
it will return an array of parameters. but when i tried this in element i am not getting the value.
also i tried to set a value in the add_rates.ctp and try to access in element, that is also not working
$this->set('params',array($params));
what to do..if anybody have idea about this please reply.. i get stucked ...
If $params is the array you are trying to pass, then try this:
<?php $this->element('your-element-name', array('params' => $params)); ?>
I have a dropdown that I want to populate when an item in another dropdown is selected. Both the dropdown are tied to data/model passed on from controller. and the first dropdown is populated from DB by calling a function in the model. Heres' the form,
echo $form->dropDownListRow($modelunit,
'superunit',
$model->getSunits(),
array(
'ajax' => array(
'type'=>'POST',
'url'=>CController::createUrl('user/getunits'),
'update'=>'#unit_id',
)));
echo CHtml::dropDownList('unit_id','', array());
Here's the action user/getunits called by Ajax.
$data=Unit::model()->findAll('sid=:sid',
array(':sid'=>(int) $_POST['superunit']));
$data=CHtml::listData($data,'id','name');
foreach($data as $value=>$name)
{
echo CHtml::tag('option',
array('value'=>$value),CHtml::encode($name),true);
}
I keep getting an error "Undefined index: superunit" when first dropdown is selected. Also, you may notice I am using form->dropDownListRow for the first dropdown while using CHtml::dropDownList for the second. That's cause I am clueless on the syntax of how exactly to make sure the dropdown is populated correctly with ajax and at also properly bind to the model.
You use $form->dropDownListRow that's why you will get $_POST['MyModelName']['superunit'] on your server side
Change you code like
$data=Unit::model()->findAll('sid=:sid',
array(':sid'=>(int) $_POST['MyModelName']['superunit']));
Where MyModelName is a model that you use)
Or like
echo CHtml::dropDownList('superunit'.....
