I want first and last record id form $dataprovider which is passed to gridview which i need to pass to this link.
array(
'name' => 'msg',
'value' => 'CHtml::link(substr(strip_tags($data->msg),0,30)." .....",Yii::app()->createUrl("Mail/view",array("id"=>$data->primaryKey,"flag"=>"inbox","tab"=>'.$tab.',"category"=>'.$category.')))',
'type' => 'raw',
'header' => 'Message',
),
Declare two attributes in your controller.
public $first=null;
public $last=null;
Define a function in controller to render your link
public function renderMailViewLink($data,$row){
// you can return anything you want here. whether a link or whatever
// access $this->first->id , $this->last->id
return CHtml::link($data->anyAttribute,array('someRoute','id'=>$data->id,'first'=>$this->first->id))
}
CActiveDataProvider has a method getData(), which return array of all active records.
in actionIndex
$dataProvider = $model->search()
$data = $dataProvider->getData();
$this->first = reset($data );
$this->last = end($data);
And finally in your view
array(
'name' => 'msg',
'value' => array($this,'renderMailViewLink'),
'type' => 'raw',
'header' => 'Message',
),
Please note this code is not tested. But thats how it can be achieved

Hi I have CRUD generated CGridView in yii. I need to add a new button to CGridView rows and hide it if appointment_status(one of CGridView column) value equals 0
This is my code of CGridView,
$this->widget('zii.widgets.grid.CGridView', array(
'id' => 'bookings-grid',
'dataProvider' => $model->search(),
'filter' => $model,
'columns' => array(
'id',
'name',
'email',
'telephone',
'time',
'employee',
'appointment_status',
'client_ip',
'link' => array(
'header' => 'Confirmation',
'type' => 'raw',
'value' => 'CHtml::button("$data->appointment_status",array("onclick"=>"document.location.href=\'".Yii::app()->controller->createUrl("controller/action",array("id"=>$data->id))."\'"))',
'visible'=>$data->appointment_status==1,
),
array(
'class' => 'CButtonColumn',
),
),
));
But all I'm getting is error stating,
Undefined variable: data
It would be great help if someone can look into it.
you can use like this:
$this->widget('zii.widgets.grid.CGridView', array(
'id' => 'bookings-grid',
'dataProvider' => $model->search(),
'filter' => $model,
'columns' => array(
'id',
'name',
'email',
'telephone',
'time',
'employee',
'appointment_status',
'client_ip',
'link' => array(
'header' => 'Confirmation',
'type' => 'raw',
'value' => function ($data) {
if ($data->appointment_status == 1) {
return CHtml::button("$data->appointment_status", array("onclick" => "document.location.href=\'" . Yii::app()->controller->createUrl("controller/action", array("id" => $data->id)) . "\'"));
} else {
return;
}
}
),
array(
'class' => 'CButtonColumn',
),
),
));
Your 'visible' handling the column visibility and not the button, you can use custom attribute on model to create and handle the button visibility.
add to your model:
public function getConfirmationButton()
{
if ($data->appointment_status == 1) {
return CHtml::button($this->appointment_status,array("onclick"=>"document.location.href=\'".Yii::app()->controller->createUrl("controller/action",array("id"=>$this->id))."\'"));
} else {
return '';
}
}
and call it in your view:
..........
'link' => array(
'header' => 'Confirmation',
'type' => 'raw',
'value' => '$data->confirmationButton',
),
...........
visible is a boolean or a PHP expression that will be evaluated to give a boolean. During the evaluation $data is assigned to the current item from the dataProvider used. $data doesn't exist outside of the evaluation function evaluateExpression(). As such the implementation should be:
`visible` => '$data->appointment_status == 1',
You need to quote value of visible key in link array. So instead of this:
'visible'=>$data->appointment_status==1
It should be:
'visible'=>'$data->appointment_status==1'
it should work now.
You will get undefined variable because visible not allow any callback.
Try this solution, it's yii2 code and i don't know much of Yii.
'delete' => function ($url, $model) {
return ($model->isVisible($model)) ?
Html::a('<span class="glyphicon glyphicon-trash"></span>',
$url,
['title' => Yii::t('app', 'Delete')]) : '';
public static function isVisible($data)
{
return ($data->appointment_status == 1) ? true : false;
}
This is follow up on this question:
Display related has_many data inside once cell in Yii TbExtendedGridView
I got that cell working, but now i have no idea how to make it sortable and filterable (filter field is hidden).
View:
$this->widget('bootstrap.widgets.TbExtendedGridView', array(
'id'=>'user-grid',
'dataProvider' => $model->search(),
'filter' => $model,
'columns' => array(
'user_name',
'favorite_color',
array(
'value'=>'$data->getAllDates()',
),
),
));
One user can have many Dates that can be single date or date range, so i have getAllDates function that fetches em all and put em all inside string so they can be represented inside single cell for that user.
Model:
public function relations()
{
return array(
'listofdates' => array(self::HAS_MANY, 'Dates', 'user_id'),
);
}
public function getAllDates()
{
$data = '';
foreach ($this->listofdates as $date) {
$data .= $date->start_date.'-'.$date->end_date;
}
return $data;
}
I have no idea how to enable filtering and search for dates column. There is no even title for it or filter field.
I can enable filter field for that column by adding 'name' => 'whatever', but of course there is no single column in database for that data so i get MYSQL error.
I'm guessing i need to create another custom function for filtering but i have no idea where to start.
you can create an additional field for filtering and sorting $datesFilter and filter like this:
in model:
public $datesFilter;
public function rules()
{
array(
array('datesFilter', 'safe', 'on'=>'search')
);
}
public function search()
{
$criteria=new CDbCriteria;
...
// filtering
if ($this->datesFilter!==null)
$criteria->addCondition('YOUR QUERY CONDITION');
...
// sorting
$sort = new CSort;
$sort->attributes =
array(
...
'datesFilter'=>=>array('asc'=>'YOUR SORT ASC', 'desc'=>'YOUR SORT DESC'),
);
}
in view:
$this->widget('bootstrap.widgets.TbExtendedGridView', array(
'id'=>'user-grid',
'dataProvider' => $model->search(),
'filter' => $model,
'columns' => array(
'user_name',
'favorite_color',
array(
'value'=>'$data->getAllDates()',
'name'=>'datesFilter',
),
),
));
Until now I have been binding input filters to the form in the module, in other words I have been creating elements in the form, adding input filters to the elements on the module side.
For example check this example
Right now im creating text field elements dynamically depending upon the requirements, like this in my form
//Form
public function addNamesTextFieldElement($names)
{
foreach($names as $name)
{
$nameTextField = new Element\Text($name->getName());
$nameTextField->setAttribute('type', "text");
$nameTextField->setLabel($name->getName());
$this->add($nameTextField );
}
}
What would be best approach where to add/attach input filters to such dynamically generated elements.
I probably wouldn't use this approach, but something like this would work, providing you have already assigned an InputFilter to the form:
public function addNamesTextFieldElement($names)
{
$factory = new InputFactory();
foreach($names as $name)
{
$nameTextField = new Element\Text($name->getName());
$nameTextField->setAttribute('type', "text");
$nameTextField->setLabel($name->getName());
$this->add($nameTextField );
$this->getInputFilter()->add(
$factory->createInput(array(
'name' => $name->getName(),
'required' => true,
'filters' => array(
array('name' => 'StripTags'),
array('name' => 'StringTrim'),
),
'validators' => array(
array(
'name' => 'StringLength',
'options' => array(
'encoding' => 'UTF-8',
'min' => 1,
'max' => 100,
),
),
),
))
);
}
}
I'm using Zend Framework 2 and I need a Dependent Dropdown. When user select an category (cat_id on my example) the system fills the subcategory (sca_id) with the correct elements.
I could do that by creating an application like this:
My form looks like:
$this->add(array(
'name' => 'cat_id',
'type' => 'Zend\Form\Element\Select',
'options' => array(
'label' => 'Categoria',
'value_options' => array(
'' => '',
),
),
));
$this->add(array(
'name' => 'sca_id',
'type' => 'Zend\Form\Element\Select',
'options' => array(
'label' => 'Sub Categoria',
'style' => 'display:none;', // Esse campo soh eh exibido qndo uma categoria for escolhida
'value_options' => array(
'' => '',
),
),
));
Note that I don't fill the value_options there, because I choose do that in my controller, where the Service Manager is avaliable:
$form = new ProdutoForm('frm');
$form->setAttribute('action', $this->url()->fromRoute('catalogo-admin', array( ... )));
// Alimenta as comboboxes...
$form->get('cat_id')->setValueOptions($this->getCategoriaService()->listarCategoriasSelect());
On the change event of cat_id I do an $.ajax to grab the elements from an Action and fill the sca_id.
That works fine!
The problem is on my validation:
$this->add(array(
'name' => 'cat_id',
'require' => true,
'filters' => array(
array('name' => 'Int'),
),
));
$this->add(array(
'name' => 'sca_id',
'require' => true,
'filters' => array(
array('name' => 'Int'),
),
));
When I submit my form it keeps saying : The input was not found in the haystack for both dropdowns...
What I'm doing wrong?
Extra questions : There's a better way to fill my dropdowns?
Ps.: I guess this question Disable notInArray Validator Zend Framework 2 asks something similar than me, but I wanted to detail more my problem.
Well, I realized that I should populate my select element before validate my form!
// SaveAction
$request = $this->getRequest();
if ($request->isPost())
{
$form = new ProdutoForm();
// Alimenta as comboboxes...
$form->get('cat_id')->setValueOptions($this->getCategoriaService()->listarCategoriasSelect());
$form->get('sca_id')->setValueOptions($this->getSubCategoriaService()->listarSubCategoriasSelect());
// If the form doesn't define an input filter by default, inject one.
$form->setInputFilter(new ProdutoFormFilter());
// Get the data.
$form->setData($request->getPost());
// Validate the form
if ($form->isValid())
{
// Valid!
}else{
// Invalid...
}
That code works nice. My form now validate perfectly!
I'm trying to use Lithiums list option with find() along with SQL's DISTINCT.
I should get an array populated with values, instead, I'm getting an empty array.
This does make sense since I'm passing in the distinct fields as one string instead of an array of elements but I don't know how else to use DISTINCT in Lithium.
Some direction would be greatly appreciated.
It may be valentines day but Lithium is not showing me too much love today :)
Model:
class ZipCodes extends \app\extensions\data\Model {
