prompt empty not showing up clistdata - yii

When the list is empty it's not showing up. It'll show up when I remove the array in 3rd parameter of dropdownlist, but my class won't work if that happens. What am I missing here?
array('name'=>'response',
type'=>'raw',
'header'=>'Send a Note',
'value'=>function($data,$row){
if ($data->response_id ===null ||$data->response_id ==11)
return CHtml::dropDownList('Response','',
CHtml::listData(table::model()->findAll(),
'response_id','response','',array('prompt'=>'Select a message')),
array('class'=>'changeStatus','id' => $data->response,'url'=>Yii::app()->createURL('url')));
else return $data->response->response;
}
),

How to delete items from an array in Vue

I have a function called updateAnswer with multiple dynamic parameters.
updateAnswer(key, answer, array = false) {
if (array) {
if(this.answers.contains.find(element => element === answer)) {
//Delete item from array if already element already exists in this.answers.contains array.
} else {
Vue.set(this.answers, key, [...this.answers.contains, answer]);
}
} else {
Vue.set(this.answers, key, answer);
}
},
I'd like to know how delete an item in the array if the value already exists in the array.
You can use method called splice:
Just reference on your array and set values in the brackets the first is referenced on the position, the second is how many datas you want to splice/delete.
The function looks like this:
this.array.splice(value, value)
Lets see on an example - you have array food= [apple, banana, strawberry] than I'm using this.food.splice(1,1)..
my array looks now like this food = [apple, strawberry] - first value in my brackets are the position, the second one is the amount of "numbers" you want to delete.
Hopefully this helps you out!
I suppose each value in this.answers.contains is unique?
Anyways, if you just want to delete the item if already exists, I suggest filter(). It should look like below:
if(this.answers.contains.find(element => element === answer)) {
this.answers.contains = this.answers.contains.filter(c => c !== answer)
}
Also, the if condition if(this.answers.contains.find(element => element === answer)) could also be replaced by if(this.answers.contains.includes(answer))
Hope that could help you.

Checkboxlist in YII AJAX filter deselecting items

I have an ajaxfilter on a YII listview. When I select an item in the checkboxlist everything works properly: ajax calls vacature/index and gives 'vacature' the right ID which I handle in my controller, so this works fine. (vacature/index?vacature=13)
Now when I uncheck the same item it does exactly the same call, so it passes the id of the changed item. I only need it to not pass the id of the de-selected item and the string to be empty.
Thanks in advance!
echo CHtml::beginForm(CHtml::normalizeUrl(array('vacature/index')), 'get', array('id'=>'filter-vacature'))
echo CHtml::checkBoxList('niveau', (isset($_GET['niveau'])) ? $_GET['niveau'] : '',
CHtml::listData(Lov::model()->findAllByAttributes(array('wat'=>'opleiding')), 'id', 'item'),
array('class'=>'niveau','template'=>'<span class="checkbox-columns">{input} {label}</span>', 'separator'=>''))
$('.niveau').change(function(){
niveau = $('.niveau').serialize();
$.fn.yiiListView.update(
'ajaxListView',
{data: niveau}
);
});
I added a comparison to check if the string is empty, and pass the working empty value:
$('.niveau').change(function(){
niveau = $('.niveau').serialize();
if(empty(niveau))
{
niveau = 'niveau%5B%5D=0';
}
$.fn.yiiListView.update(
'ajaxListView',
{data: niveau}
);
});

How to put contrasting information into a CGridView column based on a condition?

I'm looking into showing/hiding specific column data on a CGridView widget for the Wii Framework.
I have a CButtonColumn which contains 3 buttons. However, on certain conditions, I want to display something different for a particular row.
I have 3 different conditions which determin what gets displayed for particular row.
The following illustrates what I want to do:
| 1 | Title A | [hide][view][update] <-- if (condition == 'a')
| 2 | Title B | [hide][view][update] <-- if (condition == 'a')
| 3 | Title C | display text or link or button <-- if (condition == 'b')
| 4 | Title D | display alternative buttons <-- if (condition == 'c')
What is my best approach to take here?
I can't use 'visible'=> $model->processingStatus != "processed" on the column because this will remove the whole column. I need to target each row insatead.
Should I use the 'visible' parameter on each individual button? I have tried this using the commented out code below but it breaks the page.
FYI: I have successfully tried the 'visible' parameter on the CButtonColumn itself, but its not what I need. Plus not sure which row's status it is reading.
Or should I add a function to the controller? Have it do the if/else statements and return back what is to be displayed. How would this work?
Here is my code:
<?php $this->widget('zii.widgets.grid.CGridView', array(
'id'=>'my-grid',
'dataProvider'=>$model->search(),
'filter'=>$model,
'columns'=>array(
array(
'name'=>'myid',
'header'=>'ID',
),
'Title',
array(
'class'=>'CButtonColumn',
'visible'=> $model->status != "done",
'template'=>'{hide}{view}{update}',
'buttons'=>array(
'hide'=>array(
'label'=>'Hide', //Text label of the button.
'imageUrl'=>Yii::app()->request->baseUrl . '/img/icons/bulb-off.png' //Image URL of the button.
//'click'=>'function(){alert("Toggle Hide!");}', //A JS function to be invoked when the button is clicked.
//'options'=>array(), //HTML options for the button tag.
//'url'=>'javascript:void(0)', //A PHP expression for generating the URL of the button.
//'visible'=> $model->status == "done", //A PHP expression for determining whether the button is visible.
),
'view'=>array(
//Text label of the button.
'label'=>'View',
//Image URL of the button.
'imageUrl'=>Yii::app()->request->baseUrl . '/img/icons/view-record.png'
),
'update'=>array(
'label'=>'Update/Edit',
'imageUrl'=>Yii::app()->request->baseUrl . '/img/icons/edit-pencil.png',
'url'=>'Yii::app()->createUrl("metadataandchapters/create?bookid=" . $data->bookid)',
)
)
)
)
)); ?>
Hope I am making good enough sense here!
You should use visible button option, but it should be a PHP expression string, e.g. :
'visible'=> '$data->status == "done"',
http://www.yiiframework.com/doc/api/1.1/CButtonColumn#buttons-detail
Extend CButtonColumn with your own class, then you should be able to change this function to whatever you need to render or hide buttons or do any changes you want.
/**
* Renders a link button.
* #param string $id the ID of the button
* #param array $button the button configuration which may contain 'label', 'url', 'data-icon', 'imageUrl' and 'options' elements.
* #param integer $row the row number (zero-based)
* #param mixed $data the data object associated with the row
*/
protected function renderButton($id, $button, $row, $data)

using listdata only and get from another model in Yii

can i just have listdata by itself? The list doesn't list anything, all I keep getting is "Array" as the return.
I have:
$awards= $model->findAll('uid='.$uid);
return CHtml::listData($awards, 'award_id', '$data->award->name');
try this code:
$awards= $model->findAll(array('condition'=>'uid ='.$uid)); // get records from table
return CHtml::listData($awards, 'award_id', 'award_name'); // third parameter should the array value. Most of the case we use to display in combo box option text.
If you are getting from another table, then declare a variable in your award model.
public $awrd_name;
Then you have to get records using relation in criteria.
Output will be :
array("1" => "award1", "2" => "award2", "3" => "award3");

Yii Pagination Variables from DataProvider

I need certain pagination variables in my controller action.
such as:
1.Current Page Number
2.Current Page offset
3.total records displayed
i.e. 31 to 40 of 2005 records displayed
I tried the following:
$dataProvider = NodesTerms::getNodesDataFromTerms($nodeId) ;
$pagination = $dataProvider->getPagination();
var_dump($pagination->getPageCount());
//var_dump($pagination->currentPage);
I can get the Pagination Object, but zero (0) in $pagination->currentPage or $pagination->offset etc....
I need this information to dynamically generate meta page title and description on actions with page listings such as pagetitle: page 3 of 10 for American Recipes...
Appreciate any help with this.
Try setting the itemCount explicitly in your dataProvider:
'pagination'=>array(
'pageSize'=>10,
'itemCount'=>$count
)
Or use a new CPagination object:
$pagination = new CPagination($count);
$dataProvider = new CSqlDataProvider($sql, array(
// ... other config
'pagination' => $pagination
));
How this works:
The pagination's itemCount is set during creation of the data-provider and again in CSqlDataProvider's fetchData function:
$pagination->setItemCount($this->getTotalItemCount());
During creation of data-provider only the values passed to the pagination property are used, and if we don't pass itemCount value, then the default of 0 is used.
So if we want to access offset or pageCount or currentPage or itemCount before the call to fetchData we have to set the itemCount explicitly.
However if we want those values after the call to fetchData then the values are already correctly populated due to the call to setItemCount within fetchData.
An example for clarity (without passing itemCount during data-provider creation):
$dataProvider = NodesTerms::getNodesDataFromTerms($nodeId);
$pagination = $dataProvider->getPagination();
var_dump($pagination->getPageCount()); // this will be zero
$data=$dataProvider->getData(); // getData calls fetchData()
var_dump($pagination->getPageCount()); // now this will be correct value
getCurrentPage returns "the zero-based index of the current page"
http://www.yiiframework.com/doc/api/1.1/CPagination#getCurrentPage-detail
so if you're on the first page, it should be returning 0.
And as you know the page size and the total number of records that will be enough for you to generate your page title.
